Struts2（2）- 搭建struts及spring整合Demo

Struts2

简单介绍struts2整合spring项目的搭建。

工程结构图

1、创建maven工程，引入jar依赖

pom.xml文件如下，maven相关知识请参看maven学习。
属性：设置版本等信息
依赖管理：锁定依赖jar包的具体版本
依赖：

  1. spring:
  2. struts2
  3. mybatis
  4. mysql驱动
  5. c3p0
  6. slf4j
  7. junit、jstl
  8. servlet jsp
  1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  2.     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  7.     <name>s2sm Maven Webapp</name>
  8.     <url>http://maven.apache.org</url>

  180.         <finalName>s2sm</finalName>
  181.     </build>
  182. </project>

2、配置web.xml

  1. 配置spring监听器

    1. <!-- applicationContext对象仅加载一次，在服务器器启动时加载 -->
    2. <listener>
    3.     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    4. </listener>
    5. <context-param>
    6.     <param-name>contextConfigLocation</param-name>
    7.     <param-value>classpath:/config/applicationContext*.xml</param-value>
    8. </context-param>

  2. 配置struts2核心过滤器

    1. <!-- Struts2核心过滤器 -->
    2. <filter>
    3.     <filter-name>struts2</filter-name>
    4.     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    5.     <!-- 指定action所在包路径 -->
    6.     <init-param>  
    7.         <param-name>actionPackages</param-name>  
    8.         <param-value>com.topvision</param-value>  
    9.     </init-param>
    10.     <!-- 指定struts.xml文件路径，默认classpath下 -->
    11.     <init-param>
    12.         <param-name>filterConfig</param-name>
    13.         <param-value>classpath:struts.xml</param-value>
    14.     </init-param>
    15. </filter>
    16. <!-- 设置url过滤 -->
    17. <filter-mapping>
    18.     <filter-name>struts2</filter-name>
    19.     <url-pattern>/*</url-pattern>
    20. </filter-mapping>

  3. 设置编码，防止乱码

    1. <!-- 编码 -->
    2. <filter>
    3.     <filter-name>encodingFilter</filter-name>
    4.     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    5.     <init-param>
    6.         <param-name>encoding</param-name>
    7.         <param-value>UTF-8</param-value>
    8.     </init-param>
    9. </filter>
    10. <filter-mapping>
    11.     <filter-name>encodingFilter</filter-name>
    12.     <url-pattern>/*</url-pattern>
    13. </filter-mapping>

  4. 设置首页

    1. <!-- 首页设置 -->
    2. <welcome-file-list>
    3.     <welcome-file>index.html</welcome-file>
    4.     <welcome-file>index.htm</welcome-file>
    5.     <welcome-file>index.jsp</welcome-file>
    6.     <welcome-file>default.html</welcome-file>
    7.     <welcome-file>default.htm</welcome-file>
    8.     <welcome-file>default.jsp</welcome-file>
    9. </welcome-file-list>

3、applicationContext.xml

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xmlns:tool="http://www.springframework.org/schema/tool"
  6.        xmlns:tx="http://www.springframework.org/schema/tx"
  7.        xmlns:aop="http://www.springframework.org/schema/aop"
  8.        xsi:schemaLocation="
  9.         http://www.springframework.org/schema/beans 
  10.         http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
  11.         http://www.springframework.org/schema/context 
  12.         http://www.springframework.org/schema/context/spring-context.xsd
  13.         http://www.springframework.org/schema/tx 
  14.         http://www.springframework.org/schema/tx/spring-tx.xsd
  15.         http://www.springframework.org/schema/aop 
  16.         http://www.springframework.org/schema/aop/spring-aop.xsd
  17.         http://www.springframework.org/schema/tool
  18.         http://www.springframework.org/schema/tool/spring-tool-3.2.xsd
  19.         ">
  20.     <!-- 开启注解配置Bean -->
  21.     <!-- 设置扫描包路径 -->
  22.     <context:annotation-config/>
  23.     <context:component-scan base-package="com.topvision"/>
  25.     <!-- 开启注解事务 -->
  26.     <tx:annotation-driven transaction-manager="transactionManager"/>
  27.     <!-- 事务管理器 -->
  28.     <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  29.         <property name="dataSource" ref="dataSource"></property>
  30.     </bean> 
  31.     <!-- 数据库C3P0 -->
  32.     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
  33.         <property name="driverClass" value="${s2sm.jdbc.driverClass}"/>
  34. 		<property name="jdbcUrl" value="${s2sm.jdbc.url}"/>
  35.         <property name="user" value="${s2sm.jdbc.username}"/>
  36. 		<property name="password" value="${s2sm.jdbc.password}"/>
  38.         <property name="initialPoolSize" value="${s2sm.cpool.initialPoolSize}" />
  39.         <property name="minPoolSize" value="${s2sm.cpool.minPoolSize}" />
  40.         <property name="maxPoolSize" value="${s2sm.cpool.maxPoolSize}" />
  41.         <property name="acquireIncrement" value="${s2sm.cpool.acquireIncrement}" />
  42.         <property name="maxIdleTime" value="${s2sm.cpool.maxIdleTime}"/>
  43.         <property name="acquireRetryAttempts" value="${s2sm.cpool.acquireRetryAttempts}"/>
  44.         <property name="acquireRetryDelay" value="${s2sm.cpool.acquireRetryDelay}"/>
  45.     </bean>
  47.     <!-- 加载properties -->
  48.     <!-- <context:property-placeholder location="classpath:jdbc.properties"/> -->
  49.     <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  50.         <property name="locations">
  51.             <list>
  52.                 <value>classpath:/config/*.properties</value>
  53.             </list>
  54.         </property>
  55.     </bean>
  57. </beans>

4、Action编写

  1. @Controller
  2. @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
  3. public class LoginAction extends BaseAction{
  4.     private static final long serialVersionUID = -4442251270114214406L;
  5.     private String username;
  6.     private String password;
  8.     public String loginTest() {
  9.         String key = username + ":" + password;
  10.         ActionContext context2 = ActionContext.getContext(); 
  11.         context2.put("key", key);
  12.         return SUCCESS;
  13.     }
  15.     public String getUsername() {
  16.         return username;
  17.     }
  19.     public void setUsername(String username) {
  20.         this.username = username;
  21.     }
  23.     public String getPassword() {
  24.         return password;
  25.     }
  27.     public void setPassword(String password) {
  28.         this.password = password;
  29.     }
  31. }

5、配置struts.xml

struts.xml文件路径要与struts2核心过滤器中配置的路径一致，默认在classpath下即可。

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE struts PUBLIC
  3.     "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
  4.     "http://struts.apache.org/dtds/struts-2.3.dtd">
  6. <struts>
  7.     <!-- 所有匹配*.action的请求都由struts2处理 -->
  8.     <constant name="struts.action.extension" value="tv,mb" />
  9.     <!-- 主题  simple,xhtml,css_xhtml和ajax-->
  10.     <constant name="struts.ui.theme" value="simple"/>
  12.     <!-- 是否启用开发模式 -->
  13.     <constant name="struts.devMode" value="true" />
  14.     <!-- struts配置文件改动后，是否重新加载，有助于开发 -->
  15.     <constant name="struts.configuration.xml.reload" value="true" />
  16.     <!-- 每次HTTP请求系统都重新加载资源文件，有助于开发 -->
  17.     <constant name="struts.i18n.reload" value="true" />
  18.     <!-- 设置浏览器是否缓存静态内容,开发是设为false,部署后true -->
  19.     <constant name="struts.serve.static.browserCache" value="false" />
  20.     <!-- Content Model : ((package | include | bean | constant)*, unknown-handler-stack?) -->
  22.     <package name="login" namespace="/aaa" extends="struts-default">
  23.         <action name="loginTest" class="com.topvision.s2sm.login.action.LoginAction" method="loginTest">
  24.             <result>/WEB-INF/jsp/login/login.jsp</result>
  25.         </action>
  27.     </package>
  29. </struts>

6、测试

  1. 首页设置

    1. <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
    2. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    3. <html>
    4. <head>
    5. <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    6. <title>Insert title here</title>
    7. </head>
    8. <body>
    9. <a href="aaa/loginTest.tv?username=中文&password=123">请点击这个链接</a><br>  
    10. </body>
    11. </html>

  2. login.jsp
