struts2配置

环境：myeclipse7.5 + tomcat6.0

用到了9个jar包，如图。红色圈的为容易漏加的。

 

注意需在tomcat的server.xml中加

 

LoginAction.java

package com.shengsiyuan.struts2;

public class LoginAction
{
 private String username ;
 private String password;
 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 execute()
 {
   return "SUCCESS" ;
  
 }
 
 
}
struts.xml

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

 
  
   result.jsp
  
  
  

struts.xml控制着总流程：(login.jsp中：

) 名为login的action文件映射到com.shengsiyuan.struts2.LoginAction(实例化生成一个对象，每一次请求都生成一个对象)，并通过反射机制调用setter,getter方法设置username和password。最后执行后面的execute()方法，execute()返回SUCCESS,result.jsp ,即名返回值SUCCESS的文件跳转到result.jsp页面
