strtut2使用例子

例子源于struts官网

1.maven下载struts2包

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-core</artifactId>
    <version>2.3.32</version>
</dependency>

2.配置web.xml

<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>

3.model类，用于数据传输

package org.apache.struts.helloworld.model;
 
public class MessageStore {
     
    private String message;
     
    public MessageStore() {
         
        setMessage("Hello Struts User");
    }
 
    public String getMessage() {
 
        return message;
    }
 
    public void setMessage(String message) {
 
        this.message = message;
    }
 
}

4.创建action类

package org.apache.struts.helloworld.action;
 
import org.apache.struts.helloworld.model.MessageStore;
import com.opensymphony.xwork2.ActionSupport;
 
public class HelloWorldAction extends ActionSupport {
 
    private static final long serialVersionUID = 1L;
 
    private MessageStore messageStore;
     
    public String execute() throws Exception {
         
        messageStore = new MessageStore() ;
        return SUCCESS;
    }
 
    public MessageStore getMessageStore() {
        return messageStore;
    }
 
    public void setMessageStore(MessageStore messageStore) {
        this.messageStore = messageStore;
    }
 
}

5.配置struts.xml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>
 
  <constant name="struts.devMode" value="true" />
 
  <package name="basicstruts2" extends="struts-default">
    <action name="index">
      <result>/index.jsp</result>
    </action>
         
    <action name="hello" class="org.apache.struts.helloworld.action.HelloWorldAction" method="execute">
      <result name="success">/HelloWorld.jsp</result>
    </action>
  </package>
</struts>

6.浏览器访问http://localhost:8081/ssh/hello.action
