public class Address {	private String city;	private String street;		public String getCity() {		return city;	}	public void setCity(String city) {		this.city = city;	}	public String getStreet() {		return street;	}	public void setStreet(String street) {		this.street = street;	}}

新增user类

public class User {	private Address address;	private String name;	private int age;	public Address getAddress() {		return address;	}	public void setAddress(Address address) {		this.address = address;	}	public String getName() {		return name;	}	public void setName(String name) {		this.name = name;	}	public int getAge() {		return age;	}	public void setAge(int age) {		this.age = age;	}	}

js处理

var address = {};map['street']=valuemap['city']=value;var user = {}user['address']=address user['name']=zhangsanuser['age']=123$.ajax({             type:"POST",             url:url,             dataType:"json",                  contentType:"application/json;charset=utf-8",                           data:JSON.stringify(user)),            success:function(result){                dosomething....            }          });

后端接受

@PostMapping(value = "/doAdd", produces = "application/json;charset=UTF-8")	@ApiOperation("监控&勘测下单")	public Result doAdd(@RequestBody User user) {        dosomething....        return Result.ok();	}
