我工作的示例演示應用程序的異常處理在春季MVC.I我試圖Exception Handling With @ControllerAdvice
@ControllerAdvice異常處理方法不會被調用
我也跟着步驟在this鏈接描述。
但是當我運行我的應用程序出現以下錯誤
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.test.core.ApplicationException
對於以下更多細節的班我的工作
ApplicationException.java
public class ApplicationException extends RuntimeException{
/**
*
*/
private static final long serialVersionUID = -9061684361606685158L;
private ErrorStatus errorStatus;
private int msgNumber;
private Object []args;
public ApplicationException(){}
public ApplicationException(ErrorStatus errorStatus, int msgNumber,
Object[] args) {
this.errorStatus = errorStatus;
this.msgNumber = msgNumber;
this.args = args;
}
//getter setters
}
控制器類
ApplicationExceptionController.java
@Controller
@RequestMapping("/exception")
public class ApplicationExceptionController {
@RequestMapping(value="/error",method=RequestMethod.GET)
@ResponseBody
public void helloException()
{
throw new ApplicationException(ErrorStatus.NotFound,1,new Object[]{"Website"});
//here ErrorStatus is a enum class
}
}
這裏是GlobalExceptionHandler類
GlobalExceptionHandler.java
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler
public void notFount(){
System.out.println("----------CaughtApplicationException-----------");
}
}
調度-servlet.xml中

我上面的應用程序運行與http://localhost:8080/SpringExceptionHandling/exception/error這個網址
但我得到下面的異常

我經歷@ControllerAdvice exception handler method are not get called此鏈接,但仍堅持同樣的問題 請幫我以獲得解決方案。我沒有得到這個例外的真正原因。
仍然無法正常工作。是否這個代碼在你身邊?如果是的話,請你分享你正在使用的罐子名稱,我想我錯過了一些jar文件 – rachana
@rachana,spring-core,spring-web,spring-webmvc。你在使用Maven項目嗎? –
不,我沒有使用Maven項目。我在我的4.0.0版本的項目中使用了所有這些jar文件 – rachana
