1，整合Struts2

a)导入struts的jar包

struts2-core-2.1.6.jar xwork-2.1.2.jar ognl-2.6.11.jar freemarker-2.3.13.jar commons-logging-1.1.jar commons-fileupload-1.2.1.jar

b)将struts.xml文件拷贝到src目录下

c)在web.xml里配置struts的核心过滤器

<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

2，整合Spring

a)导入Spring的jar包 spring.jar commons-logging.jar

b)将applicationContext.xml文件拷贝到WEB-INF目录下

c)在web.xml里配置spring的监听器

<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

d)添加spring与struts2整合的插件 struts2-spring-plugin-2.1.6.jar

3，编写代码测试

登录页面login.jsp

<body> <form action="login" method="post"> USERNAME:<input type="text" name="username" /><br> PASSWORD:<input type="password" name="password" /><br> <input type="submit" value="登录"> </form> </body>

登录成功页面 success.jsp

LoginDao业务接口

package com.itmyhome.actioin; interface LoginDao { public boolean login(String username,String password); }

LoginDaoImpl业务接口实现

package com.itmyhome.actioin; public class LoginDaoImpl implements LoginDao { public boolean login(String username, String password) { // TODO Auto-generated method stub if("zhangsan".equals(username)&&"123".equals(password)){ return true; }else{ return false; } } }

LoginAction

package com.itmyhome.actioin; import com.opensymphony.xwork2.ActionSupport; public class LoginAction extends ActionSupport { private String username; private String password; private LoginDao loginDao; //此DAO交给spring来处理 public String execute(){ if(loginDao.login(username, password)){ return "success"; }else{ return "input"; } } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public LoginDao getLoginDao() { return loginDao; } public void setLoginDao(LoginDao loginDao) { this.loginDao = loginDao; } }

struts.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="default" namespace="/" extends="struts-default"> <action name="login" class="com.itmyhome.actioin.LoginAction"> <result name="success">/success.jsp</result> <result name="input">/login.jsp</result> </action> </package>  </struts>

applicationContext.xml配置文件

部署，启动tomcat 输入"zhangsan","123" 跳转到success.jsp 整合成功
