SpringMVC利用json接收復雜物件和陣列
阿新 • • 發佈：2019-01-26
1,SpringMVC接收復雜引數必須要在引數前加
@RequestBody
2,ajax設定引數
contentType: 'application/json;charset=utf-8'（設定傳送資料型別為json）
data: JSON.stringify(物件或者陣列)（序列化json資料）
@Controller public class SpringTest { @RequestMapping("myTest") public void springMVCTest(@RequestBody List<People> people){ System.out.println(people); } @RequestMapping("/") public String home(){ return "home.html"; } }
實體類（getter/setter略）
public class People {
private String name;
private Integer age;
private Company company;
}
public class Company {
private String name;
private Address address;
}
public class Address {
private String location;
private String phoneNum;

輸出
[People{name='小紅', age=20, company=Company{name='阿里', address=Address{location='杭州',phoneNum='88888'}}},
People{name='小王', age=22, company=Company{name='騰訊', address=Address{location='深圳', phoneNum='99999'}}}]
（本測試基於SpringMVC 5.0.8）
