最新SSM框架搭建详细教程

前言

使用框架的版本： Spring 4.0.2 RELEASE Spring MVC 4.0.2 RELEASE MyBatis 3.2.6

新建maven java web项目

使用eclipse创建maven项目，项目的最终结构以及文件如下：

pom文件内容如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.ssm.edu</groupId> <artifactId>ssm</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>ssm Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- spring版本号 --> <spring.version>4.0.2.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.2.6</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.7.7</slf4j.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <!-- 表示开发的时候引入，发布的时候不会加载此包 --> <scope>test</scope> </dependency> <!-- <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> --> <!-- spring核心包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- 导入java ee jar 包 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> </dependency> <!-- 导入Mysql数据库链接jar包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.11</version> </dependency> <!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <!-- JSTL标签类 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <!-- 格式化对象，方便输出日志 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!-- 映入JSON --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 上传组件包 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.9</version> </dependency> </dependencies> <build> <finalName>maven01</finalName> <plugins> <plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>9.2.8.v20150217</version> <configuration> <httpConnector> <port>80</port> </httpConnector> <stopKey>shutdown</stopKey> <stopPort>9966</stopPort> </configuration> </plugin> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <configuration> <verbose>true</verbose> <overwrite>true</overwrite> </configuration> </plugin> </plugins> </build> </project>

在resource文件夹新建spring-mvc.xml文件

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 --> <context:component-scan base-package="com.ssm.controller" /> <!-- 扩充了注解驱动，可以将请求参数绑定到控制器参数 --> <mvc:annotation-driven/> <!-- 静态资源处理 css js imgs --> <mvc:resources location="/resources/**" mapping="/resources"/> <!--避免IE执行AJAX时，返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 --> </list> </property> </bean> <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960" /> <!-- 启用是为了推迟文件解析，以便捕获文件大小异常 --> <property name="resolveLazily" value="true"/> </bean> <!-- 配置ViewResolver 。可用多个ViewResolver 。使用order属性排序。 InternalResourceViewResolver 放在最后--> <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="order" value="1"></property> <property name="mediaTypes"> <map> <!-- 告诉视图解析器，返回的类型为json格式 --> <entry key="json" value="application/json" /> <entry key="xml" value="application/xml" /> <entry key="htm" value="text/htm" /> </map> </property> <property name="defaultViews"> <list> <!-- ModelAndView里的数据变成JSON --> <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" /> </list> </property> <property name="ignoreAcceptHeader" value="true"></property> </bean> <!-- 定义跳转的文件的前后缀 ，视图模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 --> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>

修改web.xml文件

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- Spring和mybatis的配置文件 --> <!-- <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> --> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring监听器 --> <!-- <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> --> <!-- 防止Spring内存溢出监听器 --> <!-- <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> --> <!-- Spring MVC servlet --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>

新建model类和控制层

user类如下：

package com.ssm.model; public class User { private Integer id; private String userName; private String password; private Integer age; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName == null ? null : userName.trim(); } public String getPassword() { return password; } public void setPassword(String password) { this.password = password == null ? null : password.trim(); } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } @Override public String toString() { return "User [id=" + id + ", userName=" + userName + ", password=" + password + ", age=" + age + "]"; } }

控制层类

package com.ssm.controller; import javax.servlet.http.HttpServletRequest; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import com.ssm.model.User; @Controller @RequestMapping("/user") // /user/** public class UserController { private static Logger log=LoggerFactory.getLogger(UserController.class); // /user/test?id=1 @RequestMapping(value="/test",method=RequestMethod.GET) public String test(HttpServletRequest request,Model model){ int userId = Integer.parseInt(request.getParameter("id")); System.out.println("userId:"+userId); User user=null; if (userId==1) { user = new User(); user.setAge(11); user.setId(1); user.setPassword("123"); user.setUserName("javen"); } log.debug(user.toString()); model.addAttribute("user", user); return "index"; } }

在WEB-INF目录下新建jsp文件件

再新建index.jsp页面 index.jsp

<html> <body> <h2>Hello World!</h2> </body> </html>

使用Jetty测试

在浏览器中输入：http://localhost/user/test?id=1

Spring与MyBatis的整合

在resource文件夹新建datasource.properties文件

db.driverLocation=D:\apache-maven-3.5.3-bin\apache-maven-3.5.3\repository\mysql\mysql-connector-java\8.0.11\mysql-connector-java-8.0.11.jar db.driverClassName=com.mysql.cj.jdbc.Driver db.url=jdbc:mysql://localhost:3306/task?useSSL=false&serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8 db.username=root db.password=root #定义初始连接数 initialSize=0 #定义最大连接数 maxActive=20 #定义最大空闲 maxIdle=20 #定义最小空闲 minIdle=1 #定义最长等待时间 maxWait=60000

在resource文件夹新建spring-mybatis.xml文件

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描 --> <context:component-scan base-package="com.ssm" /> <!-- 引入配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:datasource.properties" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${db.driverClassName}" /> <property name="url" value="${db.url}" /> <property name="username" value="${db.username}" /> <property name="password" value="${db.password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="${initialSize}"></property> <!-- 连接池最大数量 --> <property name="maxActive" value="${maxActive}"></property> <!-- 连接池最大空闲 --> <property name="maxIdle" value="${maxIdle}"></property> <!-- 连接池最小空闲 --> <property name="minIdle" value="${minIdle}"></property> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="${maxWait}"></property> </bean> <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:com/ssm/mappers/*.xml"></property> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.ssm.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> </beans>

创建测试用表

-- ---------------------------- -- Table structure for `user_t` -- ---------------------------- DROP TABLE IF EXISTS `user_t`; CREATE TABLE `user_t` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_name` varchar(40) NOT NULL, `password` varchar(255) NOT NULL, `age` int(4) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; -- ---------------------------- -- Records of user_t -- ---------------------------- INSERT INTO `user_t` VALUES ('1', '测试', '345', '24'); INSERT INTO `user_t` VALUES ('2', 'javen', '123', '10');

利用MyBatis Generator自动创建代码, 在resource文件夹新建generatorConfig.xml文件

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!--导入属性配置--> <properties resource="datasource.properties"></properties> <!-- 指定数据库驱动的jdbc驱动jar包的位置 --> <classPathEntry location="D:\apache-maven-3.5.3-bin\apache-maven-3.5.3\repository\mysql\mysql-connector-java\8.0.11\mysql-connector-java-8.0.11.jar" /> <!-- context 是逆向工程的主要配置信息 --> <!-- id：起个名字 --> <!-- targetRuntime：设置生成的文件适用于那个 mybatis 版本 --> <context id="default" targetRuntime="MyBatis3"> <!--optional,旨在创建class时，对注释进行控制--> <commentGenerator> <property name="suppressDate" value="true" /> <!-- 是否去除自动生成的注释 true：是 ： false:否 --> <property name="suppressAllComments" value="true" /> </commentGenerator> <!--jdbc的数据库连接--> <jdbcConnection driverClass="${db.driverClassName}" connectionURL="${db.url}" userId="${db.username}" password="${db.password}"> </jdbcConnection> <!--非必须，类型处理器，在数据库类型和java类型之间的转换控制--> <javaTypeResolver> <!-- 默认情况下数据库中的 decimal，bigInt 在 Java 对应是 sql 下的 BigDecimal 类 --> <!-- 不是 double 和 long 类型 --> <!-- 使用常用的基本类型代替 sql 包下的引用类型 --> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- targetPackage：生成的实体类所在的包 --> <!-- targetProject：生成的实体类所在的硬盘位置 --> <javaModelGenerator targetPackage="com.ssm.pojo" targetProject=".\src\main\java"> <!-- 是否允许子包 --> <property name="enableSubPackages" value="false" /> <!-- 是否对modal添加构造函数 --> <property name="constructorBased" value="true" /> <!-- 是否清理从数据库中查询出的字符串左右两边的空白字符 --> <property name="trimStrings" value="true" /> <!-- 建立modal对象是否不可改变 即生成的modal对象不会有setter方法，只有构造方法 --> <property name="immutable" value="false" /> </javaModelGenerator> <!-- targetPackage 和 targetProject：生成的 mapper 文件的包和位置 --> <sqlMapGenerator targetPackage="com.ssm.mappers" targetProject=".\src\main\java"> <!-- 针对数据库的一个配置，是否把 schema 作为字包名 --> <property name="enableSubPackages" value="false" /> </sqlMapGenerator> <!-- targetPackage 和 targetProject：生成的 interface 文件的包和位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.ssm.dao" targetProject=".\src\main\java"> <!-- 针对 oracle 数据库的一个配置，是否把 schema 作为字包名 --> <property name="enableSubPackages" value="false" /> </javaClientGenerator> <table tableName="user_t" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> </table> </context> </generatorConfiguration>

邮件pom文件，如下图选项 自动生成的mapp类和映射xml文件如下： UserMapper接口：

package com.ssm.dao; import org.springframework.stereotype.Service; import com.ssm.pojo.User; /** * @author ASUS * */ @Service("userService") public interface UserMapper { int insert(User record); int insertSelective(User record); }

UserMapper.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="com.ssm.dao.UserMapper" > <resultMap id="BaseResultMap" type="com.ssm.pojo.User" > <constructor > <arg column="id" jdbcType="INTEGER" javaType="java.lang.Integer" /> <arg column="user_name" jdbcType="VARCHAR" javaType="java.lang.String" /> <arg column="password" jdbcType="VARCHAR" javaType="java.lang.String" /> <arg column="age" jdbcType="INTEGER" javaType="java.lang.Integer" /> </constructor> </resultMap> <insert id="insert" parameterType="com.ssm.pojo.User" > insert into user_t (id, user_name, password, age) values (#{id,jdbcType=INTEGER}, #{userName,jdbcType=VARCHAR}, #{password,jdbcType=VARCHAR}, #{age,jdbcType=INTEGER}) </insert> <insert id="insertSelective" parameterType="com.ssm.pojo.User" > insert into user_t <trim prefix="(" suffix=")" suffixOverrides="," > <if test="id != null" > id, </if> <if test="userName != null" > user_name, </if> <if test="password != null" > password, </if> <if test="age != null" > age, </if> </trim> <trim prefix="values (" suffix=")" suffixOverrides="," > <if test="id != null" > #{id,jdbcType=INTEGER}, </if> <if test="userName != null" > #{userName,jdbcType=VARCHAR}, </if> <if test="password != null" > #{password,jdbcType=VARCHAR}, </if> <if test="age != null" > #{age,jdbcType=INTEGER}, </if> </trim> </insert> </mapper>

User

package com.ssm.model; public class User { private Integer id; private String userName; private String password; private Integer age; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName == null ? null : userName.trim(); } public String getPassword() { return password; } public void setPassword(String password) { this.password = password == null ? null : password.trim(); } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } @Override public String toString() { return "User [id=" + id + ", userName=" + userName + ", password=" + password + ", age=" + age + "]"; } }

测试插入数据

创建一个测试类

package com.ssm.test; import javax.annotation.Resource; import org.apache.log4j.Logger; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.ssm.dao.UserMapper; import com.ssm.pojo.User; @RunWith(SpringJUnit4ClassRunner.class) //表示继承了SpringJUnit4ClassRunner类 @ContextConfiguration(locations = {"classpath:spring-mybatis.xml"}) public class TestMyBatis { private static Logger logger = Logger.getLogger(TestMyBatis.class); // private ApplicationContext ac = null; @Resource private UserMapper userMapper = null; // @Before // public void before() { // ac = new ClassPathXmlApplicationContext("applicationContext.xml"); // userService = (IUserService) ac.getBean("userService"); // } @Test public void test1() { User record =new User(); record.setUserName("哈哈"); record.setPassword("1"); record.setAge(1); int i = userMapper.insert(record); // System.out.println(user.getUserName()); // logger.info("值："+user.getUserName()); } }

执行main方法可以插入到数据库中的数据
