经过几天的浏览，我没有找到解决方案，所以我想我会发布。马上，对不起我的英语。
我正在尝试使用 Jhipster 的技术堆栈（Spring MVC、JPA 等）从在 Java 中运行的后端获取自定义异常到我的前端。在某些情况下，我创建了自定义异常，使用我在 Jhipster 生成的 ControllerAdvice 中添加的自定义处理程序处理它，一切正常。
在另一种情况下，我试图捕获相同的异常，但 ControllerAdvice 根本没有触发，我最终遇到了一个错误，我在前端无能为力。使用 Jhipster 生成的异常，我得到相同的不可用错误。
controllerAdvice（由 jhipster 生成）
@ControllerAdvice
public class ExceptionTranslator implements ProblemHandling, SecurityAdviceTrait {
private static final String FIELD_ERRORS_KEY = "fieldErrors";
private static final String MESSAGE_KEY = "message";
private static final String PATH_KEY = "path";
private static final String VIOLATIONS_KEY = "violations";
@Value("${jhipster.clientApp.name}")
private String applicationName;
......
@ResponseStatus(HttpStatus.CONFLICT)
@ExceptionHandler(OdoLoginAlreadyUsedException.class)
protected ResponseEntity<Object> handleLoginAlreadyUsed(OdoLoginAlreadyUsedException ex, NativeWebRequest request){
ApiError apiError = new ApiError(HttpStatus.CONFLICT);
apiError.setMessage(ex.getMessage());
return buildResponseEntity(apiError, request);
}
@ResponseStatus(HttpStatus.CONFLICT)
@ExceptionHandler(OdoEmailAlreadyUsedException.class)
protected ResponseEntity<Object> handleEmailAlreadyUsed(OdoEmailAlreadyUsedException ex, NativeWebRequest request){
ApiError apiError = new ApiError(HttpStatus.CONFLICT);
apiError.setMessage(ex.getMessage());
return buildResponseEntity(apiError, request);
}
private ResponseEntity<Object> buildResponseEntity(ApiError apiError, NativeWebRequest request) {
return new ResponseEntity<>(apiError, apiError.getStatus());
}
例外的一个例子
public class OdoLoginAlreadyUsedException extends RuntimeException{
public OdoLoginAlreadyUsedException(){
super("Ce pseudo est déjà utilisé, veuillez ré-éssayer avec un pseudo différent.");
}
}
这样可行：
休息控制器
@PostMapping("/register")
@ResponseStatus(HttpStatus.CREATED)
public ResponseEntity<AdvisorVM> registerAccount(@Valid @RequestBody AdvisorIn advisorIn) {
if (!checkPasswordLength(advisorIn.getPassword())) {
throw new InvalidPasswordException();
}
advisorIn.setCreatedBy("Platform_Advisor");
advisorIn.setCreatedDate(Instant.now());
User user = userService.registerUser(advisorIn, advisorIn.getPassword()); ....
服务
public User registerUser(UserDTO userDTO, String password){
userRepository.findOneByLogin(userDTO.getLogin().toLowerCase()).ifPresent(existingUser -> {
boolean removed = removeNonActivatedUser(existingUser);
if (!removed) {
throw new OdoLoginAlreadyUsedException();
}
});
userRepository.findOneByEmailIgnoreCase(userDTO.getEmail()).ifPresent(existingUser -> {
boolean removed = removeNonActivatedUser(existingUser);
if (!removed) {
throw new OdoEmailAlreadyUsedException();
}
});
User newUser = new User();
有了这个我的 ControllerAdvice 捕获异常，建立一个响应状态和我试图得到的错误消息
这不
休息控制器
@PostMapping("/actions/ceUser")
@PreAuthorize("hasRole(\"" + AuthoritiesConstants.ADMIN + "\")" + " ||hasRole(\"" + AuthoritiesConstants.ROLE_MANAGER + "\")")
public @ResponseBody
ResponseEntity<String> createEditUser(@Valid @RequestBody CEUser ceUser) throws URISyntaxException, JsonParseException, JsonMappingException, IOException {
User loggedUser = userService.getUserWithAuthorities().get();
var userExtraGlobal=userExtraCustomService.findByUser(loggedUser).get();
// User id is provided or not
boolean createUser = (ceUser.getId() == null);
if (createUser) log.debug("REST request to create User : {}", ceUser);
else log.debug("REST request to update User : {}", ceUser.getFirstName() + " " + ceUser.getLastName());
if (ceUser.getLogin() == null || ceUser.getLogin().isBlank()) {
throw new RuntimeException("User login should not be null or blank");
}
if (createUser){
if(userService.findOneByLogin(ceUser.getLogin().toLowerCase()).isPresent()) {
throw new OdoLoginAlreadyUsedException();
} if(userService.findOneByEmail(ceUser.getEmail()).isPresent()) {
throw new OdoEmailAlreadyUsedException();
}

使用我的自定义异常或 Jhipster 的内置异常，我在前端获得 500 状态，并带有不可解析的 json 响应，但我对此无能为力。
我尝试从我的服务而不是我的 RestController 中抛出我的异常。我尝试了不同的注释（例如，EnableMVC）和我阅读的其他内容，但我无法确定为什么它在两种情况下的响应不同。我读到有关过滤器的内容可能会妨碍 ControllerAdvice？我不知道，如果你们能指导我正确的方向！
先感谢您
编辑
资源中有一个异常处理程序捕获所有运行时异常（我的自定义异常扩展），所以它没有被分派到 ControllerAdvice ......无论如何，谢谢！
