Spring Boot HTTP状态而不会引发异常 [英] Spring Boot HTTP status without throwing exceptions

问题描述

我想返回200以外的HTTP状态，而不使用 @ExceptionHandler 注释.

I want to return HTTP status other than 200 without using the @ExceptionHandler annotation.

之所以这样做，是因为并非每次对我的应用程序的调用都会导致异常，至少在我看来，这不会导致异常状态.

The reason for this is that not every call to my application, which results in a status which is not OK should throw an exception, at least not in my opinion.

作为一个例子，如果用户试图登录系统，但是提供了不正确的密码，我认为没有理由为了能够返回401状态而为此抛出异常.相反，我希望能够从常规"方法中返回状态.

As an example, if a user is trying to log into the system, but provides an inaccurate password, I see no reason to throw an exception over this just in order to be able to return a 401 status. Instead, I would like to be able to return the status from within a "regular" method.

其背后的原因是，抛出不必要的异常既会使我的日志文件混乱，又会使用"我的日志聚合器(Rollbar/Sentry)每月津贴.

The reason behind this is that throwing unnecessary exceptions both clutters my log files, and "uses" my log aggregator (Rollbar/Sentry) monthly allowance.

我尝试使用 @ResponseStatus 和 @ResponseBody 注释方法，但是没有用.

I've tried annotating methods with @ResponseStatus and @ResponseBody, but it didn't work.

我到处寻找有关此问题的博客文章或其他文章，但找不到任何东西.

I looked around for blog posts or other articles on the issue but couldn't find anything.

知道这是否可行吗?

推荐答案

您可以使用 RessponseEntity .将/* STATUS CODE */替换为您想要的任何内容:

You can use RessponseEntity. Replace the /*STATUS CODE*/ with whatever you want:

@GetMapping("/url")
@ResponseBody
public ResponseEntity<?> handlerMethod(/*parameters*/) {
    // ...
    return ResponseEntity.status(/*STATUS CODE*/).body(...);
}
