Spring 中的自定义 Http 状态代码 [英] Custom Http Status Code in Spring

问题描述

我正在使用 Spring Boot 并且在我的业务逻辑代码中使用异常类.一个可能看起来像这样:

I am using Spring Boot and I am using Exception Classes thoughout my business logic code. One might look like this:

@ResponseStatus(HttpStatus.BAD_REQUEST)
public class ExternalDependencyException extends RuntimeException {

    public ExternalDependencyException() {
        super("External Dependency Failed");
    }
    public ExternalDependencyException(String message) {
        super(message);
    }

}

现在有异常，没有预定义的 Http 状态代码适合，所以我想使用像 460 或类似的状态代码，它仍然是免费的，但注释 ResponseStatus 只是接受枚举 HttpStatus 中的值.有没有办法在java spring boot环境中实现带有自定义状态码的Exception类?

Well now there are Exception, where no predefined Http Status code is fitting, so I would like to use a status code like 460 or similar, which is still free, but the annotation ResponseStatus just accepts values from the enum HttpStatus. Is there a way to achieve an Exception class with a custom status code in the java spring boot environment?

推荐答案

我不知道有什么方法可以用 @ResponseStatus.

I'm not aware of a way to do this with @ResponseStatus.

解决这个问题的一种方法是使用 @RestControllerAdvice.这将允许您自定义返回异常的方式.

One way to solve is this issue is with @RestControllerAdvice. This will allow you to customize how you return your Exception.

@RestControllerAdvice
public class WebRestControllerAdvice  {

    @ExceptionHandler(ExternalDependencyException.class)
    public String handleGitlabException(ExternalDependencyException ex, HttpServletResponse response) {
        try {
            response.sendError(460);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return ex.getMessage();
    }
}
