    构造所需要的jar包

    eclipse中先生成就一个web项目,在web.xml中配置spring+springmvc位置

    <?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_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>MyBatis_06_ssm</display-name> <!--Spring配置: needed for ContextLoaderListener --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- Bootstraps the root web application context before servlet initialization --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- SpringMVC配置 --> <!-- The front controller of this Spring Web application, responsible for handling all application requests --> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- Map all requests to the DispatcherServlet for handling --> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>

    spring的applicationContext.xml中配置

    <?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:context="http://www.springframework.org/schema/context" xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!-- Spring希望管理所有的业务逻辑组件,等。。。 --> <context:component-scan base-package="com.atguigu.mybatis"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <!-- 引入数据库的配置文件 --> <context:property-placeholder location="classpath:dbconfig.properties" /> <!-- Spring用来控制业务逻辑。数据源、事务控制、aop --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value="${jdbc.url}"></property> <property name="driverClass" value="${jdbc.driver}"></property> <property name="user" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!-- spring事务管理 --> <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 开启基于注解的事务 --> <tx:annotation-driven transaction-manager="dataSourceTransactionManager"/> <!-- 整合mybatis 目的:1、spring管理所有组件。mapper的实现类。 service==>Dao @Autowired:自动注入mapper; 2、spring用来管理事务,spring声明式事务 --> <!--创建出SqlSessionFactory对象 --> <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <!-- configLocation指定全局配置文件的位置 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <!--mapperLocations: 指定mapper文件的位置--> <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"></property> </bean> <!--配置一个可以进行批量执行的sqlSession,做批量操作的时候才需要 --> <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactoryBean"></constructor-arg> <constructor-arg name="executorType" value="BATCH"></constructor-arg> </bean> <!-- 扫描所有的mapper接口的实现,让这些mapper能够自动注入; base-package:指定mapper接口的包名 --> <mybatis-spring:scan base-package="com.atguigu.mybatis.dao"/> <!-- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.atguigu.mybatis.dao"></property> </bean> --> </beans>

    还有springMVC对应的spring-servlet.xml文件

    在这里插入代码片<?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!--SpringMVC只是控制网站跳转逻辑 --> <!-- 只扫描控制器 --> <context:component-scan base-package="com.atguigu.mybatis" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/"></property> <property name="suffix" value=".jsp"></property> </bean> <mvc:annotation-driven></mvc:annotation-driven> <mvc:default-servlet-handler/> </beans>
