问题描述
我正在使用Spring MVC中的异常处理示例演示应用程序。我尝试使用@ControllerAdvice异常处理
我按照此网址
但我得到以下异常

我经历这个链接，但仍然坚持同样的问题
请帮助我获得解决方案。我没有得到这个异常的实际原因。 / p>
解决方案
您的异常处理程序中缺少@EnableWebMvc注释。您的异常处理程序应该是这样的。
@EnableWebMvc
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler（{ApplicationException.class}）
public void notFount（）{
System.out.println（---------- CaughtApplicationException --- --------）;
}
@ExceptionHandler（{Exception.class}）
public void notFountGlobal（）{
System.out.println（------- --- CaughtApplicationException -----------）;
}
}
还需要告诉异常处理程序想抓住哪个方法。最后你可以指定一个方法，可以捕获所有其他异常传递它Exception.class。
您为我发布的代码段。希望它会解决您的问题
I am working on sample demo application for Exception Handling in Spring MVC.I am trying Exception Handling With @ControllerAdvice
I followed steps as describe in this link.
But when i run my application i get the following error
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.test.core.ApplicationException
For more details following are the classes I am working on
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
}
Controller class
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
}
}
And here is the GlobalExceptionHandler class
GlobalExceptionHandler.java
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler
public void notFount(){
System.out.println("----------CaughtApplicationException-----------");
}
}
dispatcher-servlet.xml

I go through @ControllerAdvice exception handler method are not get called this link but still stuck with the same problemPlease help me to get the solution.I am not getting the actual cause for this exception.
解决方案
You are missing @EnableWebMvc annotation in your Exception handler. Your Exception handler should be like this.
@EnableWebMvc
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler({ApplicationException.class})
public void notFount(){
System.out.println("----------CaughtApplicationException-----------");
}
@ExceptionHandler({Exception.class})
public void notFountGlobal(){
System.out.println("----------CaughtApplicationException-----------");
}
}
Also you need to tell exception handler method which exception you want to catch in which method. At last you can specify a method which can caught all other exception passing it Exception.class.The code snippet you post work for me. Hopefully it will resolve your problem
