postman测试传参格式

• 创建User实体

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {private Integer id;private String name;
}

1. 接口参数是集合

	@PostMapping("/test1")public String test1(@RequestBody List<User> userList) {return "SUCCESS";}

postman传参形式：

[{"id": 1,"name": "ff"},{"id": 2,"name": "dfu"}
]

测试结果：

2. bean实体传参

①创建DTO，封装List集合

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;import java.util.List;@Data
@AllArgsConstructor
@NoArgsConstructor
public class UserDTO {private List<User> userList;}

②参数传DTO

 @PostMapping("/test2")public String test2(@RequestBody UserDTO userDTO) {return "userDTO SUCCESS";}

③JSON传参形式

{"userList": [{"id": 1,"name": "ff"},{"id": 2,"name": "dfu"}]
}

④postman测试
