我有一个基本的SpringBoot 2.0.4.RELEASE应用程序。使用Spring Initializer,JPA,嵌入式Tomcat,Thymeleaf模板引擎并将其打包为可执行JAR文件。
我创建了此类来管理异常:
@ControllerAdvice
@RestControllerAdvice
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {
public RestResponseEntityExceptionHandler() {
super();
}
// 500
@ExceptionHandler({ NullPointerException.class, IllegalArgumentException.class, IllegalStateException.class, RuntimeException.class })
/*500*/
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public BodyBuilder handleInternal(final RuntimeException ex, final WebRequest request) {
logger.error("500 Status Code", ex);
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
该方法处理RuntimeException和ArithmeticException 扩展RuntimeException。
为了测试它,我创建了这个方法;
GetMapping(path = "/getUsers", consumes = "application/json", produces = "application/json")
public ResponseEntity<List<User>> testErrors(HttpServletRequest request) {
double ss = 3 /0;
return ResponseEntity.ok(userService.findAll());
}
期望它将仅返回HttpStatus.INTERNAL_SERVER_ERROR
,但返回“
{"timestamp":"2018-08-31T09:21:21.717+0000","status":500,"error":"Internal Server Error","message":"/ by zero","trace":"java.lang.ArithmeticException: / by zero\n\tat ...
使用此方法
@ExceptionHandler({ NullPointerException.class, IllegalArgumentException.class, IllegalStateException.class, RuntimeException.class })
/*500*/
public BodyBuilder handleInternal(final RuntimeException ex, final WebRequest request) {
logger.error("500 Status Code", ex);
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR);
}
我有完整的跟踪记录:{"timestamp":"2018-09-03T07:04:58.803+0000","status":500,"error":"Internal Server Error","message":"/ by zero","trace":"java.lang.ArithmeticException: / by zero\n\tat
使用这个,在控制台中我看不到任何卷曲的东西:
@ExceptionHandler({ NullPointerException.class, IllegalArgumentException.class, IllegalStateException.class, RuntimeException.class })
/*500*/
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public void handleInternal(final RuntimeException ex, final WebRequest request) {
logger.error("500 Status Code", ex);
}
和另外一个,控制台中也没有:
@ExceptionHandler({ NullPointerException.class, IllegalArgumentException.class, IllegalStateException.class, RuntimeException.class })
/*500*/
public ResponseEntity<Object> handleInternal(final RuntimeException ex, final WebRequest request) {
logger.error("500 Status Code", ex);
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
}

也许piradian并没有特别指出,但是问题似乎出在handleInternal
方法的返回类型上。在您提供的代码中,返回类型为BodyBuilder
,并且您返回由ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR)
返回的值。实际上,正如BodyBuilder
名称所暗示的那样,它表示Builder pattern的实现。在这种情况下,您实际应该做的是:
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
然后将方法的返回类型更改为ResponseEntity
或ResponseEntity<Object>
(在您的情况下,主体为空,因此实际上没有太大区别)。
但是,考虑到您的示例中没有返回正文,并且您已经用@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
注释了您的方法,您所能做的就是将返回类型更改为void
而不返回任何内容-这正是piradian的建议。这也应该工作。

尝试一下:
@ExceptionHandler({NullPointerException.class, IllegalArgumentException.class, IllegalStateException.class, RuntimeException.class})
/* 500 */
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public void handleInternal(final RuntimeException ex, final WebRequest request) {
logger.error("500 Status Code", ex);
}

使用这个
@RestControllerAdvice//insted of @ControllerAdvice
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {
@ExceptionHandler(value = { Exception.class, RuntimeException.class })
@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public BodyBuilder handleInternal(final RuntimeException ex, final WebRequest request) {
logger.error("500 Status Code", ex);
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
