SSH------jsp将数据传递给action

来源：互联网发布：java 线程池串行编辑：程序博客网时间：2024/05/25 18:09

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"%>
<!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>
<form id="form1" action="login">

<label>用户名:</label>
<input type="text" name="username" />
<br>

<label>密码：</label>
<input type="password" name="userpwd" />

<button type="submit">登陆</button>
</form>
</body>
</html>

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

struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

<constant name="struts.enable.DynamicMethodInvocation" value="false" />

<constant name="struts.devMode" value="true" />
<package name="default" namespace="/" extends="struts-default">
<action name="login" class="com.wxf.wwsy.action.LoginAction">
<result name="success">/index.jsp</result>
<result name="false">/login.jsp</result>
</action>
</package>
</struts>

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"%>
<!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>
<form id="form1" action="login">

<label>用户名:</label>
<input type="text" name="managerUser.username" />
<br>

<label>密码：</label>
<input type="password" name="managerUser.userpwd" />

<button type="submit">登陆</button>
</form>
</body>
</html>

LoginAction:
package com.wxf.wwsy.action;

import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionSupport;
import com.wxf.wwsy.model.ManagerUser;

public class LoginAction extends ActionSupport{

private ManagerUsermanagerUser;

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";*/
}

}

struts.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">

<constant name="struts.enable.DynamicMethodInvocation" value="false" />

<constant name="struts.devMode" value="true" />
<package name="default" namespace="/" extends="struts-default">
