春@ExceptionHandler犯規處理錯誤

我有一個像春@ExceptionHandler犯規處理錯誤

@RestController 
public class CustomerRestController { 

    @Autowired 
    private CustomerManagementService customerManagementService; 

    /** 
    * 
    * @return 
    */ 
    @ExceptionHandler(CustomerNotFoundException.class) 
    public ResponseEntity<ClinetErrorInformation> rulesForCustomerNotFound() { 

     ClinetErrorInformation clinetErrorInformation = new ClinetErrorInformation("Clinet was not found"); 
     return new ResponseEntity<>(clinetErrorInformation, HttpStatus.NOT_FOUND); 
    } 

    @RequestMapping(value = {"/customer/{id}"}) 
    public Customer requestCustomerById(@PathVariable String id) throws CustomerNotFoundException { 
     return customerManagementService.findCustomerById(id); 
    } 

}

唯一的例外是由類沒有處理類：

嚴重：com.mycompany.crmproject.services.customer.CustomerNotFoundException 在 ... com.mycompany.crmproject.restcontroller.CustomerRestController.requestCustomerById（CustomerRestController.java:44）

調度的Servlet：

      </map> 
     </property> 

     <property name="ignoreAcceptHeader" value="false"/> 

    </bean> 

</beans>

什麼可能是爲什麼這個錯誤沒有處理，並在browesr我只能看到空白頁。

你的配置看起來不錯，我不能在Tomcat中重現你的問題。你能展示你的POM嗎？你可以嘗試使用不同的網絡容器？ – artemisian

@artemisian我上傳了pom – pshemek

確定異常被拋出？看起來像服務返回null，這就是你看到的。

是我：嚴重：com.mycompany.crmproject.services.customer.CustomerNotFoundException在... com.mycompany.crmproject.restcontroller.CustomerRestController.requestCustomerById（CustomerRestController.java:44） – pshemek

這不僅僅是日誌信息，這樣可以該異常是否被記錄和吞噬？ –

異常由aop代理處理，Thx尋求幫助 – pshemek

添加@ResponseBody到您的異常處理方法。使用@RestController默認情況下，只有@RequestMapping方法使用@ResponseBody。

也許你有另一個異常解析器註冊。將優先級更改爲ExceptionHandlerExceptionResolver。

如果使用註釋配置：

@Bean 
public ExceptionHandlerExceptionResolver exceptionHandlerExceptionResolver()   
{ 
    ExceptionHandlerExceptionResolver exceptionHandlerExceptionResolver = new ExceptionHandlerExceptionResolver(); 
    exceptionHandlerExceptionResolver.setOrder(1); 
    return exceptionHandlerExceptionResolver; 
}

如果您使用XML配置：

<bean class="org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver"> 
    <property name="order" value="1"/> 
</bean>

增加了ResponseBody註釋，但它沒有什麼區別。 – pshemek

@pshemek我已經更新了我的答案。 – alfcope
