@ControllerAdvice无法处理catch块中的异常

Question

我正在我的Spring（5.0）RestFul应用程序中尝试使用GlobalExceptionHandler。

这是我的控制器类：

@Controller
@RequestMapping(path = "/", produces = MediaType.APPLICATION_JSON_VALUE)
public class OrderController {

@Autowired
private OrderService orderService;

private static final Logger logger = LogManager.getLogger(Thread.currentThread().getClass().getName());


@ExceptionHandler(Exception.class)
public  ResponseEntity<com.example.of.rest.acknowledgement.Acknowledgement> handleError(HttpServletRequest request, Exception e)   {
    System.out.println("excpetion :(");
    if(e!=null) {
        e.printStackTrace();
    }
    com.example.of.rest.acknowledgement.ObjectFactory ackFact = new com.example.of.rest.acknowledgement.ObjectFactory();
    com.example.of.rest.acknowledgement.Acknowledgement ackXml = ackFact.createAcknowledgement();
    ackXml.setMessage(e.getMessage());
    ackXml.setStatus(Constants.ACK_STATUS.ERROR);
    java.util.logging.Logger.getLogger(getClass().getName()).log(Level.SEVERE, "Request: " + request.getRequestURL() + " raised " + e);
    return new ResponseEntity<com.example.of.rest.acknowledgement.Acknowledgement>(ackXml, HttpStatus.INTERNAL_SERVER_ERROR);
}

@PostMapping("/orders/save")
@Consumes("application/json; charset=UTF-8")
public ResponseEntity<com.example.of.rest.acknowledgement.Acknowledgement> saveOrderAuthenticateConnector(HttpServletRequest request, @RequestBody String requestJson) throws Exception {
    HttpStatus httpStatus = null;
    com.example.of.rest.acknowledgement.Acknowledgement ackXml = null;
    String message = null;
    String status = null;
    ConnectorData connectorData =  null;
    try {
        String newToken = (String) request.getAttribute("token");
        if(newToken != null) {
            connectorData = orderService.saveConnectorDatatoDB(connectorData, "Not Retrieved", requestJson, Constants.DATA_STATUS_DB.RECIEVED, null, null, null);
            connectorData = orderService.processAndSaveOrder(requestJson, connectorData);
            connectorData = orderService.saveConnectorDatatoDB(connectorData, connectorData.getChannelOrderId(), requestJson, connectorData.getDataStatus(), 
                    connectorData.getProcessStatus(), connectorData.getErrorMessage(), connectorData.getProcessError());
            ackXml = responseService.populateAcknowledgement(connectorData, status, message);
            if(Constants.ACK_STATUS.SUCCESS.equals(ackXml.getStatus())) {
                httpStatus = HttpStatus.OK;

            }else {
                httpStatus = HttpStatus.BAD_REQUEST;
            }
        }else {
            message = "We were not able to authorize the request.";
            status = Constants.ACK_STATUS.ERROR;
            httpStatus = HttpStatus.UNAUTHORIZED;
        }
    }catch(Exception ex) {
        ex.printStackTrace();
        message = ex.getMessage();
        status = Constants.ACK_STATUS.ERROR;
        httpStatus = HttpStatus.INTERNAL_SERVER_ERROR;
        connectorData = orderService.saveConnectorDatatoDB(connectorData, connectorData.getChannelOrderId(), requestJson, connectorData.getDataStatus(), 
                connectorData.getProcessStatus(), connectorData.getErrorMessage(), connectorData.getProcessError());

    }
    if(ackXml == null) {
        ackXml = responseService.populateAcknowledgementResponse(status, message);
    }
    return new ResponseEntity<com.example.of.rest.acknowledgement.Acknowledgement>(ackXml, httpStatus);

}
}

行中的catch块中发生异常。

connectorData = orderService.saveConnectorDatatoDB(connectorData, connectorData.getChannelOrderId(), requestJson, connectorData.getDataStatus(), 
                    connectorData.getProcessStatus(), connectorData.getErrorMessage(), connectorData.getProcessError());

我还定义了一个GlobalExceptionHandler：

@ControllerAdvice(basePackages = { "com.example.of.controller" })
@EnableWebMvc
@Order(Ordered.HIGHEST_PRECEDENCE)
public class ExceptionController extends ResponseEntityExceptionHandler{

    @ExceptionHandler(value = Exception.class)
    public ResponseEntity<com.example.of.rest.acknowledgement.Acknowledgement> handleError(HttpServletRequest request, Exception e)   {
        System.out.println("excpetion :(");
        if(e!=null) {
            e.printStackTrace();
        }
        com.example.of.rest.acknowledgement.ObjectFactory ackFact = new com.example.of.rest.acknowledgement.ObjectFactory();
        com.example.of.rest.acknowledgement.Acknowledgement ackXml = ackFact.createAcknowledgement();
        ackXml.setMessage(e.getMessage());
        ackXml.setStatus(Constants.ACK_STATUS.ERROR);
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, "Request: " + request.getRequestURL() + " raised " + e);
        return new ResponseEntity<com.example.of.rest.acknowledgement.Acknowledgement>(ackXml, HttpStatus.INTERNAL_SERVER_ERROR);
    }
}

启动服务器时，将选择Exception处理程序类： 16：46：18,926信息[org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]（ServerService线程池-83）寻找@ControllerAdvice：名称空间“ dispatcher-servlet”的WebApplicationContext：启动日期[7月4日25 16:46:17 IST 2019]；父级：根WebApplicationContext 16：46：18,984信息[org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver]（ServerService线程池-83）在exceptionController中检测到@ExceptionHandler方法

这是我的文件夹结构：

我已在组件扫描中添加了所有文件夹：

@ComponentScan(basePackages = {"com.example.of", "com.example.of.config"}` )

但是当我调用url时，发生异常，我得到200（确定）响应，这不是我期望的。我想得到500或其他任何错误状态。

这是控制台日志：
