SSH------jsp将数据传递给action

1.采用的是action的属性传递
传递过来的参数名是action属性名（必须要求名字一致）
比如传递过来的数据：
http://localhost/Struts2_1/login?username=123&userpwd=123
参数名是username和userpwd，那么创建的action类中就有username和userpwd这两个属性

login.jsp；
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

用户名:
username" />




密码：
userpwd" />


登陆

index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

         /index.jsp
         /login.jsp
       
   



LoginAction:
package com.wxf.wwsy.action;


import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionSupport;


public class LoginAction extends ActionSupport{


private String username;
private String userpwd;


public String getUsername() {
return username;
}




public void setUsername(String username) {
this.username = username;
}




public String getUserpwd() {
return userpwd;
}




public void setUserpwd(String userpwd) {
this.userpwd = userpwd;
}




@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
System.out.println("用户名:"+this.username+",，密码："+this.userpwd);
if( this.username.equals("123") && this.userpwd.equals("123")){
return "success";
}else{
return "false";
}
/*return "success";*/
}


}

2.采用的是试题属性传
创建一个实体类ManagerUser：
在action类中创建实体类属性：
ManagerUser:
package com.wxf.wwsy.model;


public class ManagerUser {


private Long userId;
private String username;
private String userpwd;
private Integer roleid;
public String getUsername() {
return username;
}

public Long getUserId() {
return userId;
}


public void setUserId(Long userId) {
this.userId = userId;
}


public void setUsername(String username) {
this.username = username;
}
public String getUserpwd() {
return userpwd;
}
public void setUserpwd(String userpwd) {
this.userpwd = userpwd;
}
public Integer getRoleid() {
return roleid;
}
public void setRoleid(Integer roleid) {
this.roleid = roleid;
}

}




login.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

用户名:
managerUser.username" />




密码：
managerUser.userpwd" />

public class LoginAction extends ActionSupport{


private ManagerUser managerUser;

public ManagerUser getManagerUser() {
return managerUser;
}


public void setManagerUser(ManagerUser managerUser) {
this.managerUser = managerUser;
}


@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
System.out.println("用户名:"+managerUser.getUsername()+",，密码："+managerUser.getUserpwd());
if( managerUser.getUsername().equals("123") && managerUser.getUserpwd().equals("123")){
return "success";
}else{
return "false";
}
/*return "success";*/
}
