springmvc使用javabean作為請求參數

1 首先寫兩個javabean對象 person 和 address 代碼如下。兩個類之間的關系如代碼中

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
                + "]";
    }
    
    

}

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 + "]";
    }
    
    

}

2 編寫控制器使用person來作為請求參數

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;
    }

}

3 寫測試類：可以用httpclient來模擬。我這使用表單進行測試的。表單代碼

<%@ 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>

測試：

點擊提交：為了方便看到控制器中的對象，進行斷點。

表單中的屬性都已經被填充到person對象中

繼續向下看到address對象

已經都被賦值成功
