来源：互联网发布：手机北斗导航软件编辑：程序博客网时间：2024/05/02 00:08

整合Spring，换句话说，也就是让spring的IOC功能为我们的struts action注入逻辑组件

首先需要加载struts2-spring-plugin-2.0.6.jar这个包，这个是关键，他可以帮我们把struts2和spring仅仅整合在一起

首先是web.xml

<?xml version="1.0" encoding="utf-8"?>

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/bean.xml</param-value>

</context-param>

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

</listener>

<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-name>aaa</filter-name>

<filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp </filter-class>

</filter>

<filter-mapping>

<filter-name>aaa</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

</web-app>

其次是struts2.xml

<?xml version="1.0" encoding="GBK"?>

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd">

<result name="error">/error.jsp</result>

<result name="success">/welcome.jsp</result>

</action>

</package>

</struts>

最关键的是bean.xml，完成为struts2 action的注入

<?xml version="1.0" encoding="GBK"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

</bean>

</beans>

LoginAction

package lee;

import com.opensymphony.xwork2.Action;

public class LoginAction implements Action {

private String username;

private String password;

private String tip;

private MyService ms;

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 String getTip() {

return tip;

}

public void setTip(String tip) {

this.tip = tip;

}

public String execute() throws Exception {

if(ms.valid(this.getUsername(), this.getPassword())){

return SUCCESS;

}

else{

return ERROR;

}

public MyService getMs() {

return ms;

}

public void setMs(MyService ms) {

this.ms = ms;

}

MyService及实现

package lee;

public interface MyService

{

boolean valid(String username , String pass);

}

package lee;

public class MyServiceImpl implements MyService

{

public boolean valid(String username , String pass)

{ System.out.println(username);

if (username.equals("高") && pass.equals("1234") )

{

return true;

}

return false;

}

struts.properties

struts.i18n.encoding=gb2312

　　 <%@ page contentType="text/html; charset=gb2312"%>
