mybatis准备

bean,dao,mybatis全局配置文件,映射文件,什么乱七八糟的基本配置准备好

SpringMVC准备

在web.xml里面配置

<!-- 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.xml的同级目录的spring-servlet.xml文件配置

<?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"

    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

  <!-- SpringMVC控制网站跳转逻辑 -->
  <!-- 只扫描控制器 -->
  <context:component-scan base-package="bean" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
  </context:component-scan>

  <context:component-scan base-package="dao" 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>

spring准备

配置springIOC容器随web一起启动,在web.xml里面配置

<!--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>

spring的配置文件applicationContext.xml的配置

<?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"
  xsi:schemaLocation="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">
  
  <!-- Spring管理所有的业务逻辑组件 -->  
  <context:component-scan base-package="com">
    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
  </context:component-scan>
  
  <!-- 引入数据库配置文件 -->
  <context:property-placeholder location="classpath:jdbcconfig.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="${jdbc.usename}"></property>
    <property name="password" value="${jdbc.password}"></property>
  </bean>
  
  <!-- spring的事务管理 -->
  <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
    作用目的:1.spring来管理所有组件,比如那些mapper实现类
          这样就不用在代码里面写getmapper了
          比如service层调用Dao层的时候,就直接@Auto wired:自动注入mapper就行
        2.spring来管理事务,比如spring的声明式事务
   -->
   <!-- 配置出一个SqlSessionFactory对象 -->
   <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <!-- configLocation指定mybatis的全局配置文件的位置 -->
    <property name="configLocation" value="classpath:mybatis.xml"></property>
    <!-- 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  -->
  <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,让这些mapper能够自动注入 -->
   <mybatis-spring:scan base-package="dao"/>
   <!--也可以这样写 
   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="dao"></property>
   </bean>
   -->
</beans>
