Struts2+Spring整合
Struts2和Spring整合,创建一个OA工程
1、整合struts2
1)导入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。暂时导入这些jar包，到时候需要再倒入。
2)将struts.xml文件放置在OA工程的src目录下。
3)在web.xml里面配置struts2用到的核心过滤器。
- < 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 >
<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)导入spring的jar包:spring.jar
2)将applicationContext.xml文件放置在OA工程的WEB-INF目录下。
3)在web.xml里面配置spring用到的监听器。
- < listener >
- < listener-class > org.springframework.web.context.ContextLoaderListener </ listener-class >
- </ listener >
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
4)添加struts2-spring整合的插件:struts2-spring-plugin-2.0.12.jar,如果不使用这个插件，则需要在struts.xml里面配置:
- < constant name = "struts.objectFactory" value = "org.apache.struts2.spring.StrutsSpringObjectFactory" />
<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />
3、测试struts2和spring整合对不对?
写一个jsp页面login.jsp来测试:
- < %@ 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 >
<%@ 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>
写一个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;
- }
- @Override
- public String execute() throws Exception {
- if (loginService.isLogin(userName, password))
- return SUCCESS;
- else
- return INPUT;
- }
- }
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;
}
@Override
public String execute() throws Exception {
if(loginService.isLogin(userName, password))
return SUCCESS;
else
return INPUT;
}
}
写一个Service
- package com.struts2.service;
- public interface LoginService {
- boolean isLogin(String userName,String password);
- }
package com.struts2.service;
public interface LoginService {
boolean isLogin(String userName,String password);
}
写一个Service的实现
- 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 ;
- }
- }
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里面配置:
- < 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 >
<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里面配置:
- < 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 >
<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>
启动tomcat，分别输入hello和world，提交,结果为hello和world。说明struts2和spring整合成功。
