Spring+Struts2调整

Spring+Struts2整合

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 stubif("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" name="code"> <bean id="loginDao" /><bean id="loginAction" ref="loginDao" /></bean>

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