配置web.xml

• 配置编码过滤器

        
          <filter>
              <filter-name>encodingFilterfilter-name>
              <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
              
              <init-param>
                  <param-name>encodingparam-name>
                  <param-value>utf-8param-value>
              init-param>
              
              <init-param>
                  <param-name>forceEncodingparam-name>
                  <param-value>trueparam-value>
              init-param>
      
          filter>
          <filter-mapping>
              <filter-name>encodingFilterfilter-name>
              <url-pattern>/url-pattern>
          filter-mapping>

• 配置MVC 核心控制器 DispatcherServlet

          
          <servlet>
              <servlet-name>springmvcservlet-name>
              <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
              
              <init-param>
                  <param-name>contextConfigLocationparam-name>
                  <param-value>classpath:spring-conf/SpringMvc.xmlparam-value>
              init-param>
              
              <load-on-startup>1load-on-startup>
          servlet>
          <servlet-mapping>
              <servlet-name>springmvcservlet-name>
              <url-pattern>/url-pattern>
          servlet-mapping>
      

• 初始化Spring容器 配置监听 ContextLoaderListener

        
          <context-param>
              <param-name>contextConfigLocationparam-name>
              <param-value>classpath:spring-conf/SpringContext.xmlparam-value>
          context-param>
      
          <listener>
              <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
          listener>

配置SpringContext.xml

该配置文件用于初始化Sprng容器 和 整合mybatis

• 配置全局数据源

  <context:property-placeholder location="classpath:jdbc.properties"/>
  
      <bean id="myDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
          <property name="driverClass" value="${driver}"/>
          <property name="jdbcUrl" value="${url}"/>
          <property name="user" value="${user}"/>
          <property name="password" value="${pwd}"/>
      bean>
  

• 整合Mybatis

  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
          <property name="dataSource" ref="myDataSource"/>
          <property name="configLocation" value="classpath:mybatis-conf/mybatis-config.xml"/>
          <property name="typeAliasesPackage" value="edu.lsl.domain"/>
          <property name="mapperLocations" value="classpath:edu/lsl/mapper/**/*.xml"/>
      bean>
  
      <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
          <property name="basePackage" value="edu.lsl.mapper"/>
      bean>
  

配置springmvc.xml

<beans
        xmlns="http://www.springframework.org/schema/beans"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:context="http://www.springframework.org/schema/context"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
">
    <context:component-scan base-package="edu.lsl.controller,edu.lsl.mapper,edu.lsl.service"/>
    <mvc:annotation-driven/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    bean>
    <mvc:default-servlet-handler/>
beans>

注意：

• 记得将tomcat的servlet-API.jar 添加到工程
