如何在Spring Boot Rest api响应的ResponseEntity中添加自定义属性

Question

@GetMapping("/todo/{id}")
 public Todo getTodoById(@PathVariable String id) {
        int todoId = Integer.parseInt(id);
        Todo todoItem = todoRepository.findById(todoId);
         ResponseEntity.ok(todoItem);
    }

{
    "id": 13,
    "title": "title13",
    "status": "not started"
}

{
  "status": "success",
  "data": {
    "id": 13,
    "title": "title13",
    "status": "not started"
  },
  "error": null,
  "statusCode": 200
}

{
  "status": "failure",
  "data": {},
  "error": "bad request",
  "statusCode": 400
}

Answer 1

好吧，而不是回来

ResponseEntity.ok(todoItem);

您显然需要返回类似

ResponseEntity.ok(new Response(todoItem));

与

public class Response {

    private String status = "success";

    private Object data;

    private String error;

    private int statusCode = 200;

    // Constructor, getters and setters omitted
}
