How to get a 409 for ObjectOptimisticLockingFailureException with Spring Boot?
问题
我知道Spring Boot默认会为导致状态码为409 CONFLICT的异常呈现Thymeleaf模板，模板位于error/409.html。然而，默认情况下，ObjectOptimisticLockingFailureException会导致500 SERVER ERROR。
我可以使用@ControllerAdvice来处理异常，然后"手动"重定向到error/409.html模板，就像下面这样：
@ControllerAdvice
public class GlobalControllerAdvice {
@ResponseStatus(HttpStatus.CONFLICT)
@ExceptionHandler({DataIntegrityViolationException.class, ObjectOptimisticLockingFailureException.class})
public ModelAndView handleConflict(HttpServletRequest request, Exception e) {
ModelAndView result = new ModelAndView("error/409");
result.addObject("url", request.getRequestURL());
return result;
}
}
由于ObjectOptimisticLockingFailureException不是我自己的代码的一部分，我无法使用@ResponseStatus(HttpStatus.CONFLICT)来注解它以使其返回409状态码。
是否可以将ObjectOptimisticLockingFailureException映射到409并在Spring Boot中使用默认的错误模板机制？
英文:
I know that Spring Boot will render a Thymeleaf template at error/409.html for an exception that leads to a statuscode of 409 CONFLICT by default. However, it seems that ObjectOptimisticLockingFailureException gives a 500 SERVER ERROR by default.
I am able to handle the exception and "manually" redirect to the error/409.html template using a @ControllerAdvice like this:
@ControllerAdvice
public class GlobalControllerAdvice {
@ResponseStatus(HttpStatus.CONFLICT)
@ExceptionHandler({DataIntegrityViolationException.class, ObjectOptimisticLockingFailureException.class})
public ModelAndView handleConflict(HttpServletRequest request, Exception e) {
ModelAndView result = new ModelAndView("error/409");
result.addObject("url", request.getRequestURL());
return result;
}
}
Since ObjectOptimisticLockingFailureException is not part of my own code, I cannot annotate it with @ResponseStatus(HttpStatus.CONFLICT) to have a 409.
Is it possible to map ObjectOptimisticLockingFailureException to 409 and use the default error template mechanism for error codes in Spring Boot?

我们可以尝试使用以下的 ResponseEntity：
@ExceptionHandler({DataIntegrityViolationException.class, ObjectOptimisticLockingFailureException.class})
public ResponseEntity<ModelAndView> handleConflict(HttpServletRequest request, Exception e) {
ModelAndView result = new ModelAndView("error/409");
result.addObject("url", request.getRequestURL());
return new ResponseEntity<>(result, HttpStatus.CONFLICT);
}
英文:
We can try with ResponseEntity as below
@ExceptionHandler({DataIntegrityViolationException.class, ObjectOptimisticLockingFailureException.class})
public ResponseEntity<ModelAndView> handleConflict(HttpServletRequest request, Exception e) {
ModelAndView result = new ModelAndView("error/409");
result.addObject("url", request.getRequestURL());
return new ResponseEntity<>(result, HttpStatus.CONFLICT);
}

这可能会起作用
@Bean(name="simpleMappingExceptionResolver")
public SimpleMappingExceptionResolver
createSimpleMappingExceptionResolver() {
SimpleMappingExceptionResolver r =
new SimpleMappingExceptionResolver();
Properties mappings = new Properties();
mappings.setProperty("ObjectOptimisticLockingFailureException", "error/409");
r.setExceptionMappings(mappings);
return r;
}

This might work
@Bean(name="simpleMappingExceptionResolver")
public SimpleMappingExceptionResolver
createSimpleMappingExceptionResolver() {
SimpleMappingExceptionResolver r =
new SimpleMappingExceptionResolver();
Properties mappings = new Properties();
mappings.setProperty("ObjectOptimisticLockingFailureException", "error/409");
r.setExceptionMappings(mappings);
return r;
}

可以捕获 `ObjectOptimisticLockingFailureException` 异常，并重新抛出一个状态码为 409 的异常。
```java
try {
// 在此处执行你的任务
} catch (ObjectOptimisticLockingFailureException e) {
var ex = new ClientErrorException(409, e);
throw ex;
}
英文:
Could you catch the exception ObjectOptimisticLockingFailureException and re-throw an exception with 409?
try {
//perform your task here
} catch (ObjectOptimisticLockingFailureException e) {
var ex = new ClientErrorException(409, e);
throw ex;
}
