搭建spring+mybatis+struts2环境的配置文件

1、web.xml配置

<?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>mgr</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>

   <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
   classpath:config/spring_config.xml<!-- spring整合配置 -->
   classpath:config/spring_quartz.xml<!-- 配置定时任务时使用 -->
  </param-value>
 </context-param>
 <!-- 设置由Sprng载入的Log4j配置文件位置，默认为src下，如果修改配置文件路径则需要修改 -->
<!--  <context-param>
  <param-name>log4jConfigLocation</param-name>
  <param-value>classpath:config/log4j.properties</param-value>
 </context-param>
 Spring刷新Log4j配置文件变动的间隔,单位为毫秒
 <context-param>
  <param-name>log4jRefreshInterval</param-name>
  <param-value>10000</param-value>
 </context-param>
 <listener>
  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
 </listener> -->

 <!-- Spring监听器 -->
 <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>
 <listener>
  <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
 </listener>

 <!-- Struts2 -->
 <filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  <!-- 默认strut.xml放在src目录下，如需修改，需要增加init配置 -->
 </filter>
 <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>

 <session-config>
  <session-timeout>30</session-timeout>
 </session-config>

</web-app>

2、spring_config.xml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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 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

        <!-- 在每次空闲连接回收器线程(如果有)运行时检查的连接数量-->
        <property name="numTestsPerEvictionRun" value="3" />

        <!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->
        <property name="poolPreparedStatements" value="true" />

        <!-- 用来检测连接是否有效的sql，要求是一个查询语句。如果validationQuery为null，testOnBorrow、testOnReturn、testWhileIdle都不会其作用 -->
        <property name="validationQuery" value="SELECT 1" />

        <!-- 申请连接的时候检测，如果空闲时间大于timeBetweenEvictionRunsMillis，执行validationQuery检测连接是否有效 -->
        <property name="testWhileIdle" value="true" />

        <!-- 申请连接时执行validationQuery检测连接是否有效，设置为false，默认是true，value值为true时候配置会降低性能7-10倍 -->
        <property name="testOnBorrow" value="false" />

        <!-- 归还连接时执行validationQuery检测连接是否有效，做了这个配置会降低性能 -->
        <property name="testOnReturn" value="false" />

        <!-- 连接泄漏回收参数，当可用连接数少于3个时才执行 -->
        <property name="removeAbandoned" value="true" />

        <!-- 连接泄漏回收参数，180秒，泄露的连接可以被删除的超时值 -->
        <property name="removeAbandonedTimeout" value="180" />

        <!-- 配置监控统计拦截的filters -->
<!--         <property name="filters" value="slf4j" /> -->
    </bean>

    <!-- 2、配置sqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" scope="prototype" >
        <!-- 加载数据源 -->
        <property name="dataSource" ref="dataSource"></property>

    <!-- 4、采用自动扫描方式创建mapper(dao) bean -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.develop.*.*.dao" />
        <property name="sqlSessionTemplateBeanName" value="sqlSessionTemplate" />

    <!-- 5、加载Service组件 ,需要在Service的实现类Impl上方添加注解@Service，否则会报异常-->
    <context:component-scan  base-package="com.develop.*.*.service.impl"></context:component-scan>

    <!-- 6、配置事务管理器 -->
    <!-- MyBatis默认使用Spring JDBC的事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>

3、mybatis_config.xml配置

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE configuration

PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

"
http://mybatis.org/dtd/mybatis-3-config.dtd
">

<configuration>        

    <!-- 全局的参数配置，如开启二级缓存等 -->    

    <settings>

        <!-- 配置延迟加载,按需加载对象属性 -->

        <setting name="lazyLoadingEnabled" value="true"/>  

        <setting name="aggressiveLazyLoading" value="false"/> 

    </settings>

    <!-- 使用别名 -->

    <typeAliases>

        <!-- 为包下的所有文件设置别名，别名为类名，不分大小写 -->

        <package name="com.develop.**.model"/>

    </typeAliases>

</configuration>

4、struts.xml配置，默认放在src下，如果修改需要修改web.xml中配置

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
 "http://struts.apache.org/dtds/struts-2.3.dtd">

 <constant name="struts.multipart.maxSize" value="52428800" />
 <constant name="struts.enable.SlashesInActionNames" value="true" />
 <constant name="struts.enable.DynamicMethodInvocation" value="false" />
 <constant name="struts.custom.i18n.resources" value="resource/message_zh_CN" /> -->

 <!-- 请求格式：namespace/action
  package：包
   * name：包名，唯一的，必选项
   * namespace：命名空间，唯一的，相当于房间号。可选项，省略情况下是"/"。页面中请求连接的前半部分
   * extends：继承
   * extends="struts-default"：struts2框架底层提供的核心包struts2-core-2.3.3.jar下的struts-default.xml文件
   * 为什么要继承这个struts-default.xml文件？
   * 因为struts2框架底层提供的struts-default.xml声明了所有的拦截器和拦截器栈，
    知道在struts2框架运行时执行struts-default.xml文件中的拦截器栈。
   * 如果不继承struts-default.xml文件，就没有办法使用struts2框架提供的所有拦截器
  -->
