从零开始学习SSH框架笔记之四 几个关键配置文件备忘(模板)

不多说，直接上代码。关于注释我尽量写详细点。

1、web.xml

 <?xml version="1.0" encoding="UTF-8"?>
  <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
      <!-- ********************struts2******************** -->
      <!-- struts2的过滤器 -->
      <filter>
          <filter-name>struts2</filter-name>
          <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
          <!-- 配置struts2的配置文件路径
          <init-param>
              <param-name>config</param-name>
              <param-value>
                  struts.xml
              </param-value>
          </init-param>
          -->
      </filter>

      <filter-mapping>
          <filter-name>struts2</filter-name>
          <url-pattern>/*</url-pattern>
      </filter-mapping>

      <!-- ********************spring******************** -->
      <!-- 配置spring的监听器，用以实现依赖注射 -->
      <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>

      <!-- 配置spring的配置文件的读取路径 -->
      <context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
      </context-param>

      <!-- 配置spring的缓存清除监听器，可选 -->
      <listener>
          <listener-class>
              org.springframework.web.util.IntrospectorCleanupListener</listener-class>
      </listener>

      <!-- 配置设置spring框架编码的过滤器，可选 -->
      <filter>
          <filter-name>encodingFilter</filter-name>
          <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
          <init-param>
              <param-name>encoding</param-name>
              <param-value>UTF-8</param-value>
          </init-param>
      </filter>

      <!-- ********************hibernate******************** -->
      <!-- 配置hibernate的过滤器
      <filter>
          <filter-name>hibernateFilter</filter-name>
          <filter-class>
              org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
      </filter>
      -->

      <!-- 配置映射路径
      <filter-mapping>
          <filter-name>hibernateFilter</filter-name>
          <url-pattern>*.do</url-pattern>
      </filter-mapping>
      -->

      <!-- ********************other******************** -->
      <!-- 配置session超时的时间 -->
      <session-config>
          <session-timeout>40</session-timeout>
      </session-config>

      <!-- 配置欢迎页面 -->
      <display-name>AGUI</display-name>
      <welcome-file-list>
          <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
  </web-app>

2、applicationContext.xml（放置spring的配置文件，包括hibernate的配置文件）

 <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE beans PUBLIC
      "-//SPRING//DTD BEAN//EN"
      "http://www.springframework.org/dtd/spring-beans.dtd">
  <beans>
      <import resource="classpath:database.xml" />

      <bean id="userDao" class="com.ssh.daoimpl.UserDaoImpl">
          <property name="sessionFactory">
              <ref bean="sessionFactory"/>
          </property>
      </bean>

      <bean id="userService" class="com.ssh.serviceimpl.UserServiceImpl">
          <property name="userDao" ref="userDao"></property>
      </bean>

      <bean id="regAction" class="com.ssh.action.RegAction">
          <property name="userService" ref="userService"></property>
      </bean>

       <bean id="listUserAction" class="com.ssh.action.ListUserAction">
           <property name="userService" ref="userService"></property>
       </bean>

       <bean id="deleteUserAction" class="com.ssh.action.DeleteUserAction">
           <property name="userService" ref="userService"></property>
       </bean>
  </beans>    

3、database.xml（放置spring的配置文件，包括hibernate的配置文件）

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE beans PUBLIC
     "-//SPRING//DTD BEAN//EN"
     "http://www.springframework.org/dtd/spring-beans.dtd">
 <beans>
     <bean id="configBean"
         class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
         <property name="location">
             <value>classpath:dataSource.properties</value>
         </property>
     </bean>

     <!--C3P0 数据源-->
     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
         <!-- 指定连接数据库的驱动 -->
         <property name="driverClass" value="${dataSource.driverClassName}"/>
         <!-- 指定连接数据库的URL -->
         <property name="jdbcUrl" value="${dataSource.url}"/>
         <!-- 指定连接数据库的用户名 -->
         <property name="user" value="${dataSource.username}"/>
         <!-- 指定连接数据库的密码 -->
         <property name="password" value="${dataSource.password}"/>
         <!-- 指定连接数据库连接池的最大连接数 -->
         <property name="maxPoolSize" value="500"/>
         <!-- 指定连接数据库连接池的最小连接数 -->
         <property name="minPoolSize" value="10"/>
         <!-- 指定连接数据库连接池的初始化连接数 -->
         <property name="initialPoolSize" value="5"/>
         <!-- 指定连接数据库连接池的连接的最大空闲时间 -->
         <property name="maxIdleTime" value="60"/>
         <!--JDBC的标准参数，用以控制数据源内加载的PreparedStatements数量. 如果maxStatements与maxStatementsPerConnection均为0，则缓存被关闭。Default: 0-->
         <property name="maxStatements" value="0"/>
         <!-- 在当前连接数耗尽的时候，一次获取的新的连接数    -->
         <property name="acquireIncrement" value="3"/>
     </bean> 

     <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
         <property name="dataSource" ref="dataSource" />
         <property name="hibernateProperties">
             <props>
                 <prop key="hibernate.dialect">${dataSource.dialect}</prop>
                 <prop key="hibernate.show_sql">true</prop>
                 <prop key="hibernate.hbm2ddl.auto">update</prop>
             </props>
         </property>
         <property name="mappingResources">
             <list>
                 <value>com/ssh/bean/user.hbm.xml</value>
             </list>
         </property>
     </bean>

     <!-- 事务管理器（拦截器） -->
     <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
         <property name="sessionFactory" ref="sessionFactory" />
     </bean>

  </beans>

4、dataSource.properties（保存数据库的连接信息）

 dataSource.driverClassName=oracle.jdbc.driver.OracleDriver
 dataSource.url=jdbc:oracle:thin:@ZHUNIAN-THINK:1521:XE
 dataSource.username=zhunian
 dataSource.password=密码
 dataSource.dialect=org.hibernate.dialect.OracleDialect

5、struts.xml（放置struts的配置文件）

 <?xml version="1.0" encoding="UTF-8" ?>
 <!DOCTYPE struts PUBLIC
     "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
     "http://struts.apache.org/dtds/struts-2.1.dtd">
  <struts>
      <package name="user" extends="struts-default">
          <action name="RegAction" class="regAction">
              <result name="success">/list.jsp</result>
              <result name="input">/save.jsp</result>
          </action>
          <action name="ListUserAction" class="listUserAction">
              <result name="success">/list.jsp</result>
              <result name="input">/index.jsp</result>
          </action>
          <action name="DeleteUserAction" class="deleteUserAction">
              <result name="success">/list.jsp</result>
              <result name="input">/index.jsp</result>
          </action>
      </package>
  </struts>
