1、整合struts2
1)匯入strut2的jar包:commons-logging-1.0.4.jar,freemarker-2.3.8.jar,ognl-2.6.11.jar,struts2-core-2.0.12.jar,xwork-2.06.jar。暫時匯入這些jar包，到時候需要再倒入。
2)將struts.xml檔案放置在OA工程的src目錄下。
3)在web.xml裡面配置struts2用到的核心過濾器。
<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class></filter><filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern></filter-mapping>
2、整合spring
1)匯入spring的jar包:spring.jar
2)將applicationContext.xml檔案放置在OA工程的WEB-INF目錄下。
3)在web.xml裡面配置spring用到的監聽器。
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>
4)添加struts2-spring整合的外掛程式:struts2-spring-plugin-2.0.12.jar,如果不使用這個外掛程式，則需要在struts.xml裡面配置:
<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />
3、測試struts2和spring整合對不對?
寫一個jsp頁面login.jsp來測試:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ taglib prefix="s" uri="/struts-tags" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body> <s:form action="Login" method="post"> <s:textfield name="userName" label="userName"></s:textfield> <s:password name="password" label="password"></s:password> <s:submit label="submit"></s:submit> </s:form></body></html>
寫一個LoginAction
package com.struts2.action;import com.opensymphony.xwork2.ActionSupport;import com.struts2.service.LoginService;public class LoginAction extends ActionSupport {private LoginService loginService;private String userName;private String password;public void setLoginService(LoginService loginService) {this.loginService = loginService;}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;}@Overridepublic String execute() throws Exception {if(loginService.isLogin(userName, password))return SUCCESS;elsereturn INPUT;}}
寫一個Service
package com.struts2.service;public interface LoginService {boolean isLogin(String userName,String password);}
寫一個Service的實現
package com.struts2.service.impl;import com.struts2.service.LoginService;public class LoginServiceImpl implements LoginService {public boolean isLogin(String userName, String password) {if("hello".equals(userName) && "world".equals(password))return true;else return false;}}
在struts.xml裡面配置:
<package name="struts2" extends="struts-default"> <action name="Login" class="loginAction"> <result name="success">/result.jsp</result> <result name="input">/login.jsp</result> </action> </package>
在applicationContext.xml裡面配置:
<bean id="loginService" class="com.struts2.service.impl.LoginServiceImpl"></bean> <bean id="loginAction" class="com.struts2.action.LoginAction" scope="prototype"> <property name="loginService" ref="loginService"></property> </bean>
啟動tomcat，分別輸入hello和world，提交,結果為hello和world。說明struts2和spring整合成功。
