在我的 InvitationService 文件中抛出异常。
if (response != null && response.getStatus() == HttpStatus.SC_CONFLICT) {
throw new UserAlreadyExistException("User Already Exists");
}
我这样定义了一个自定义异常
public class UserAlreadyExistException extends RuntimeException{
public UserAlreadyExistException(String message) {
super(message);
}
}
这是我的控制器
@RestController
@RequestMapping("/invitations")
@Api(value = "Invitation APIs")
public class InvitationController {
@Autowired
InvitationService invitationService;
@PostMapping
@ApiOperation(value = "Invite tenant user")
public ResponseEntity<InvitationResponseDTO> inviteTenantUser(@RequestBody InvitationRequestDTO invitationRequestDTO) {
invitationService.invite(invitationRequestDTO);
return new ResponseEntity<>(new InvitationResponseDTO("success"), HttpStatus.OK);
}
}
和 ControllerAdvice 类
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;
@ControllerAdvice()
public class ControllerExceptionHandler {
@ExceptionHandler(UserAlreadyExistException.class)
public ResponseEntity<Object> handleUserAlreadyExistException(UserAlreadyExistException ex) {
return new ResponseEntity<>(ex.getMessage(), HttpStatus.CONFLICT);
}
}
问题是,当服务出现异常时,仍然抛出状态码500,而我调试时,并没有通过断点进入
ControllerExceptionHandler
我不确定,但尝试在您的异常处理程序类上使用
@RestControllerAdvice
而不是 @ControllerAdvice
。
@RestControllerAdvice
public class ControllerExceptionHandler {
@ExceptionHandler(value = UserAlreadyExistException.class)
public ResponseEntity<Object>
handleUserAlreadyExistException(UserAlreadyExistException ex) {
return new ResponseEntity<>(ex.getMessage(), HttpStatus.CONFLICT);
}
}
我很确定 ControllerAdvice 只处理 RuntimeException 性质的异常,Exception 是检查性质的,因此必须显式捕获然后包装为 ControllerAdvice 处理它的运行时。
您可以尝试像这样创建异常处理程序(将 WebRequest 作为输入参数添加到您的方法):
@ControllerAdvice
public class ControllerExceptionHandler {
@ExceptionHandler(CustomException.class)
public ResponseEntity<Object> handleInputException(CustomException exception, WebRequest webRequest) {
// your code here with breakpoint
}
}
