首先在頁面新增一個表單.

    <form action="springmvc/testPojo" method="post">
        <input type="text" name="username" />
        <br>
        <input type="text" name="email" />
        <br>
        <input type="text" name="address.city" />
        <br>
        <input type="text" name="address.provincial" />
        <br>
        <input type="text" name="age" />
        <br>
        <input type="submit" value="提交" />
    </form>
 

	@RequestMapping("/testPojo")
	public String testPojo(User user){
		System.out.println(user);
		return SUCCESS;
	}

該應用應該還包含級聯模式，所以裡面有一個Address類。

package com.yoni.springmvc.entities;

public class User {

	private String username;
	private String email;
	private Address address;
	private int age;
	
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	public Address getAddress() {
		return address;
	}
	public void setAddress(Address address) {
		this.address = address;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "User [username=" + username + ", email=" + email + ", address=" + address + ", age=" + age + "]";
	}
}
 

package com.yoni.springmvc.entities;

public class Address {

	private String city;
	private String provincial;
	
	public String getCity() {
		return city;
	}
	public void setCity(String city) {
		this.city = city;
	}
	public String getProvincial() {
		return provincial;
	}
	public void setProvincial(String provincial) {
		this.provincial = provincial;
	}
	@Override
	public String toString() {
		return "Address [city=" + city + ", provincial=" + provincial + "]";
	}
}
 

User [username=aa, [email protected], address=Address [city=wuhan, provincial=hubei], age=36]
