springmvc使用javabean作为请求参数

1  首先写两个javabean对象  person 和 address 代码如下。两个类之间的关系如代码中

复制代码
package cn.bean.demo.bo;



public class Person {



private String name;


private String number;


private String sex;


private String age;


private Address address;


public String getName() {


return name;


}


public void setName(String name) {


this.name = name;


}



public String getNumber() {


return number;


}



public void setNumber(String number) {


this.number = number;


}



public String getSex() {


return sex;


}



public void setSex(String sex) {


this.sex = sex;


}



public String getAge() {


return age;


}



public void setAge(String age) {


this.age = age;


}



public Address getAddress() {


return address;


}



public void setAddress(Address address) {


this.address = address;


}



@Override


public String toString() {


return "Person [name=" + name + ", number=" + number + ", sex=" + sex + ", age=" + age + ", address=" + address

+ "]";


}



}

复制代码
复制代码
package cn.bean.demo.bo;



public class Address {


private String city;



private String province;




public String getCity() {


return city;


}



public void setCity(String city) {


this.city = city;


}



public String getProvince() {


return province;


}



public void setProvince(String province) {


this.province = province;


}


@Override

public String toString() {


return "Address [city=" + city + ", province=" + province + "]";


}



}

复制代码

 

2   编写控制器 使用person来作为请求参数

复制代码
package cn.bean.demo.service;



import org.springframework.stereotype.Controller;


import org.springframework.web.bind.annotation.RequestMapping;


import org.springframework.web.bind.annotation.RequestMethod;



import cn.bean.demo.bo.Person;



@Controller


@RequestMapping("/PojoService")


public class PojoService {


public final static String SUCCEEDD="show";


@RequestMapping(value="/testPojo",method=RequestMethod.POST)


public String testPojo(Person person){


System.out.println("testPojo  person :"+person);



System.out.println(person.getAddress());



return SUCCEEDD;


}


}

复制代码

3   写测试类：可以用httpclient来模拟。 我这使用表单进行测试的。 表单代码

复制代码
<%@ 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 action="PojoService/testPojo" method="post">


username:<input type="text" name="name"/>


<br>


number: <input type="text" name="number"/>


<br>


sex: <input type="text" name="sex"/>


<br>


age:  <input type="text" name="age"/>


<br>


province:  <input type="text" name="address.province"/>


<br>



city: <input type="text" name="address.city"/>


<br>



<input type="submit" value="subit"/>


</form>



</body>


</html>

复制代码

 

测试：

点击提交：为了方便看到控制器中的对象 ，进行断点。

表单中的属性都已经被填充到person对象中

继续向下 看到address对象

已经都被赋值成功
