java response status_java – Spring @ResponseStatus返回空响应

Why response from annotated endpoints is empty?

因为你的方法返回void(没有body的意思).状态代码 – 它不是一个正文.

您可以尝试此操作以返回具有消息明确性的响应：

@RequestMapping(value = "/{id}", method = RequestMethod.DELETE)

public ResponseEntity delete(@PathVariable("id") String id) {

repo.removeById(id);

return new ResponseEntity<>("Your message here", HttpStatus.OK);

}

而不是ResponseEntity< String>你可以把ResponseEntity< YourCustomObject>然后返回新的ResponseEntity<>(yourCustomObject实例,HttpStatus.OK);它将在响应期间转换为JSON.

你也可以这样做：

@ResponseStatus(value = HttpStatus.OK,reason =“某种原因”)

在这种情况下,您将返回以下内容：

{

"timestamp": 1504007793776,

"status": 200,

"error": "OK",

"message": "Some reason",

"path": "/yourPath"

}
