springboot怎么返回404_自定義SpringBoot REST API 404返回信息

自定義SpringBoot REST API 404返回信息

在訪問SpringBoot的REST接口時，如果請求的地址不存在Spring會返回如下JSON信息

{

"timestamp": 1492063521109,

"status": 404,

"error": "Not Found",

"message": "No message available",

"path": "/restapi/xxx"

}

我們可以通過實現ErrorController來定制化返回的JSON，例子如下：

@RestController

public class RestNotFoundFilter implements ErrorController {

private static final String NOT_FOUND = "404";

private static final String ERROR_PATH = "/error";

@RequestMapping(value = ERROR_PATH)

@ResponseStatus(value = HttpStatus.NOT_FOUND)

public RestResponse handleError() {

RestResponse response = new RestResponse();

response.setCode(NOT_FOUND);

response.setMessage("Request resource not found.");

return response;

}

@Override

public String getErrorPath() {

return ERROR_PATH;

}

}

示例代碼中的RestResponse是一個通用返回體Java bean，自己定義.
