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。
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。
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:
3、测试struts2和spring整合对不对?
写一个jsp页面login.jsp来测试:
写一个Service的实现
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。
Xml代码
- <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。
Xml代码
- <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:
Xml代码
- <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:
Html代码
- <%@ 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
Java代码
- 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
Java代码
- 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
Java代码
- 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:
Xml代码
- <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:
Xml代码
- <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。
