spring+springMVC+mybatis____一个ssm项目的整合

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"

	<!-- 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">

	</bean>

	<!-- 开启基于注解的事务 -->
	<tx:annotation-driven transaction-manager="dataSourceTransactionManager"/>
	
	<!--

			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>

	</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"?>

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

		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">

	<mvc:default-servlet-handler/>
</beans>
