@ControllerAdvice無法捕捉org.springframework.dao.EmptyResultDataAccessException

我目前正在使用java-configured spring 4構建的api，它使用全局異常處理程序將服務器上引發的所有異常包裝到json對象中。除了由jdbcTemplate方法queryForObject（）引發的EmptyResultDataAccessException之外，我已經設法解決了我遇到的每個異常。它目前正在爲我可以拋出的其他異常而努力，但在這個特定的例外上失敗。任何幫助，將不勝感激。@ControllerAdvice無法捕捉org.springframework.dao.EmptyResultDataAccessException

控制器忠告：

@ControllerAdvice 
public class GlobalExceptionHandler extends ResponseEntityExceptionHandler { 

    private static final Logger logger = Logger.getLogger(GlobalExceptionHandler.class); 

    // 400 
    @ExceptionHandler(IncorrectResultSizeDataAccessException.class) 
    protected ResponseEntity<Object> handleEmptyResultDataAccessException(IncorrectResultSizeDataAccessException ex, HttpHeaders headers, 
     HttpStatus status, WebRequest request) { 
     logger.info(ex.getClass() 
      .getName()); 
     final ApiError apiError = new ApiError.Builder(HttpStatus.BAD_REQUEST, ex.getLocalizedMessage(), "no results found").build(); 
     return handleExceptionInternal(ex, apiError, headers, apiError.getStatus(), request); 
    } 
    @Override 
    protected ResponseEntity<Object> handleMethodArgumentNotValid(MethodArgumentNotValidException ex, HttpHeaders headers, 
     HttpStatus status, WebRequest request) { 
     logger.info(ex.getClass() 
      .getName()); 
     ApiError apiError = new ApiError.Builder(HttpStatus.BAD_REQUEST, ex.getLocalizedMessage(), 
      getAllErrorsFromBindingResult(ex.getBindingResult())).build(); 
     return handleExceptionInternal(ex, apiError, headers, apiError.getStatus(), request); 
    } 
    //... 
    // 500 
    @ExceptionHandler({Exception.class, IOException.class, DaoException.class}) 
    public ResponseEntity<Object> handleAll(final Exception ex, final WebRequest request) { 
     logger.info(ex.getClass() 
       .getName()); 
     logger.error("error", ex); 

     final ApiError apiError = new ApiError.Builder(HttpStatus.BAD_REQUEST, ex.getLocalizedMessage(), "error occurred").build(); 
     return new ResponseEntity<Object>(apiError, new HttpHeaders(), apiError.getStatus()); 
} 

    // Helper Methods 

    private List<String> getAllErrorsFromBindingResult(BindingResult ex) { 
     List<String> errors = new ArrayList<>(); 
     ex.getFieldErrors() 
       .forEach(fieldError -> errors.add(fieldError.getField() + ": " + fieldError.getDefaultMessage())); 
     ex.getGlobalErrors() 
       .forEach(objectError -> errors.add(objectError.getObjectName() + ": " + objectError.getDefaultMessage())); 
     return errors; 
    } 
}

應用程序配置：

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = "app") 
@Import(SwaggerConfig.class) 
public class AppConfig extends WebMvcConfigurerAdapter { 

    @Override 
    public void addViewControllers(ViewControllerRegistry registry) { 
     super.addViewControllers(registry); 
    } 

    @Override 
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { 
     configurer.enable(); 
    } 

    @Override 
    public void addCorsMappings(CorsRegistry registry) { 
     registry.addMapping("/**") 
      .allowedOrigins("http://localhost:7070"); 
    } 

    @Override 
    public void addResourceHandlers(ResourceHandlerRegistry registry) { 
     registry.addResourceHandler("swagger-ui.html") 
      .addResourceLocations("classpath:/META-INF/resources/"); 

     registry.addResourceHandler("/webjars/**") 
      .addResourceLocations("classpath:/META-INF/resources/webjars/"); 
    } 
}

應用程序初始化程序：

public class AppInitializer implements WebApplicationInitializer { 

    @Override 
    public void onStartup(ServletContext servletContext) throws ServletException { 

     AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext(); 
     ctx.register(CeciAppConfig.class); 
     ctx.setServletContext(servletContext); 

     ServletRegistration.Dynamic dynamic = servletContext.addServlet("ceci-admin-service-dispatcher", new DispatcherServlet(ctx)); 

     dynamic.setLoadOnStartup(1); 
     dynamic.addMapping("/"); 
    } 

}

你可能現在已經想通了這一點。但是，我在你的異常處理程序類，方法注意到我假設你要使用處理EmptyResultDataAccessException例外，適當命handleEmptyResultDataAccessException實際配置趕基於註釋
IncorrectResultSizeDataAccessException例外：

@ExceptionHandler(IncorrectResultSizeDataAccessException.class)
