本文介绍如何在SpringMVC框架中实现前端表单数据到后端POJO对象的自动绑定，包括User对象及其关联Address对象的字段映射。

首先建立POJO类

public class User {
	private String name;
	private Integer age;
	private Address address;
	public User() {
		// TODO Auto-generated constructor stub
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	public Address getAddress() {
		return address;
	}
	public void setAddress(Address address) {
		this.address = address;
	}
	@Override
	public String toString() {
		return "User [name=" + name + ", age=" + age + ", address=" + address
				+ "]";
	}
}

User类中有个关联类Address

public class Address {
	private String province;
	private String city;
	public Address() {
		// TODO Auto-generated constructor stub
	}
	public String getProvince() {
		return province;
	}
	public void setProvince(String province) {
		this.province = province;
	}
	public String getCity() {
		return city;
	}
	public void setCity(String city) {
		this.city = city;
	}
	@Override
	public String toString() {
		return "Address [province=" + province + ", city=" + city + "]";
	}
}

前端的表格代码

<form action="springmvc/testPojo" method="post">
		name:<input type="text" name="name" value="andy">
		age:<input type="text" name="age" value="12">
		province:<input type="text" name="address.province" value="hunan">
		city:<input type="text" name="address.city" value="cs">
		<input type="submit" >
	</form><br>

controller的调用

@Controller
@RequestMapping("/springmvc")
public class TestSpringMVC {
	private static final String SUCCESS = "success";
	
	@RequestMapping("/testPojo")
	public String testPojo(User user){
		System.out.println(user);
		return SUCCESS;
	}
	
}

结果：

User [name=andy, age=12, address=Address [province=hunan, city=cs]]

测试总结：

如果想要前端数据自动封装到对象中，要有set、get方法，也要保持名字一致
