写在前面：

小伙伴儿们，大家好！今天给大家分享一个SSM项目实战系列——cms系统；

第一篇是SSM框架搭建，后续会持续更新，敬请期待！

思维导图：

1，配置文件引入

1.1，创建Maven项目，添加依赖；

pom.xml文件：

<dependencies>     <!-- 添加Servlet支持 -->     <dependency>       <groupId>javax.servlet</groupId>       <artifactId>javax.servlet-api</artifactId>       <version>3.1.0</version>     </dependency>     <dependency>       <groupId>javax.servlet.jsp</groupId>       <artifactId>javax.servlet.jsp-api</artifactId>       <version>2.3.1</version>     </dependency>     <!-- 添加jtl支持 -->     <dependency>       <groupId>javax.servlet</groupId>       <artifactId>jstl</artifactId>       <version>1.2</version>     </dependency>     <!-- 添加Spring支持 -->     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-core</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-beans</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-tx</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-context</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-context-support</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-web</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-webmvc</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-aop</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-aspects</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-jdbc</artifactId>       <version>4.1.7.RELEASE</version>     </dependency>     <dependency>       <groupId>org.mybatis</groupId>       <artifactId>mybatis-spring</artifactId>       <version>1.2.3</version>     </dependency>     <!-- 添加日志支持 -->     <dependency>       <groupId>log4j</groupId>       <artifactId>log4j</artifactId>       <version>1.2.17</version>     </dependency>     <dependency>       <groupId>org.slf4j</groupId>       <artifactId>slf4j-log4j12</artifactId>       <version>1.7.12</version>     </dependency>     <!-- 添加mybatis支持 -->     <dependency>       <groupId>org.mybatis</groupId>       <artifactId>mybatis</artifactId>       <version>3.3.0</version>     </dependency>     <!-- jdbc驱动包  -->     <dependency>       <groupId>mysql</groupId>       <artifactId>mysql-connector-java</artifactId>       <version>5.1.37</version>     </dependency>     <!-- 添加shiro支持 -->     <dependency>       <groupId>org.apache.shiro</groupId>       <artifactId>shiro-core</artifactId>       <version>1.2.4</version>     </dependency>     <dependency>       <groupId>org.apache.shiro</groupId>       <artifactId>shiro-web</artifactId>       <version>1.2.4</version>     </dependency>     <dependency>       <groupId>org.apache.shiro</groupId>       <artifactId>shiro-spring</artifactId>       <version>1.2.4</version>     </dependency>     <!-- 添加百度编辑器ueditor支持 -->     <dependency>       <groupId>commons-fileupload</groupId>       <artifactId>commons-fileupload</artifactId>       <version>1.3.1</version>     </dependency>     <!-- apache公共包 -->     <dependency>       <groupId>commons-codec</groupId>       <artifactId>commons-codec</artifactId>       <version>1.10</version>     </dependency>     <dependency>       <groupId>commons-lang</groupId>       <artifactId>commons-lang</artifactId>       <version>2.5</version>     </dependency>     <dependency>       <groupId>commons-beanutils</groupId>       <artifactId>commons-beanutils</artifactId>       <version>1.8.0</version>     </dependency>     <dependency>       <groupId>commons-collections</groupId>       <artifactId>commons-collections</artifactId>       <version>3.2.1</version>     </dependency>     <dependency>       <groupId>commons-logging</groupId>       <artifactId>commons-logging</artifactId>       <version>1.1.1</version>     </dependency>     <dependency>       <groupId>net.sf.ezmorph</groupId>       <artifactId>ezmorph</artifactId>       <version>1.0.6</version>     </dependency>     <!-- 添加连接池druid支持 -->     <dependency>       <groupId>com.alibaba</groupId>       <artifactId>druid</artifactId>       <version>1.0.16</version>     </dependency>   </dependencies>

这里有的jar包还需要我们手动导入：

导入之后记得添加jar包：

1.2，Resources资源文件；

我们在main目录下新建两个文件夹，分别是java和resources，并把cms标记为Sources目录，resources标记为Resources目录；

导入5个配置文件：分别是Spring，SpringMVC，MyBatis和日志相关的配置文件；

ManagerMapper.xml（注意文件路径）：

<?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.cms.dao.ManagerDao">  <resultMap type="Manager" id="ManagerResult">   <result property="id" column="id"/>   <result property="userName" column="userName"/>   <result property="password" column="password"/>  </resultMap> </mapper>

log4j.properties：

log4j.rootLogger=DEBUG, Console #Console log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.layout=org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n log4j.logger.java.sql.ResultSet=INFO log4j.logger.org.apache=INFO log4j.logger.java.sql.Connection=DEBUG log4j.logger.java.sql.Statement=DEBUG log4j.logger.java.sql.PreparedStatement=DEBUG

mybatis-config.xml：

2，创建数据库；

创建数据库db_cms，并加上一张表t_manager：

我们添加一条数据进去即可；

3，项目结构搭建；

dao数据访问层：ManagerDao接口：

package com.cms.dao; /**  * 管理员Dao接口  * @author user  *  */ public interface ManagerDao { }

这里要对应上文的ManagerMapper.xml文件，形成映射，这是MyBatis核心文件；

entity实体层：Manager实体类：

package com.cms.entity; /**  * 管理员实体  * @author user  *  */ public class Manager {     private Integer id; // 编号     private String userName; // 用户名     private String password; // 密码     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;     }     public String getPassword() {         return password;     }     public void setPassword(String password) {         this.password = password;     } }

这里就是一个与数据库表t_manager相对应的实体类；还有与mybatis-config.xml相对应，里面的别名就是实体层；

service事务层：ManagerService接口：

package com.cms.service; /**  * 管理员Service接口  * @author user  *  */ public interface ManagerService { }

ManagerServiceImpl实现类：

package com.cms.service.impl; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.cms.dao.ManagerDao; import com.cms.service.ManagerService; /**  * 管理员Service实现类  * @author user  *  */ @Service("managerService") public class ManagerServiceImpl implements ManagerService{  @Resource  private ManagerDao managerDao; }

这属于事务层，通过继承具体实现该类；

controller控制层：ManagerController类：

package com.cms.controller; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.cms.service.ManagerService; /**  * 管理员Controller层  * @author user  *  */ @Controller @RequestMapping("/manager2") public class ManagerController {     @Resource     private ManagerService managerService; }

具体的控制层，先搭个框架；

Shiro认证层：自定义MyRealm类：

package com.cms.realm; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.AuthenticationInfo; import org.apache.shiro.authc.AuthenticationToken; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.subject.PrincipalCollection; /**  * 自定义Reaml  * @author user  *  */ public class MyRealm extends AuthorizingRealm{     @Override     protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {         // TODO Auto-generated method stub         return null;     }     @Override     protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {         // TODO Auto-generated method stub         return null;     } }

4，框架测试；

我们在配置完tomcat环境之后，将cms项目导入进去，运行即可；

当运行出现index.jsp文件的内容时，表示SSM框架已经搭建成功了！
