问题描述
我想同时处理正常请求和休息/ ajax请求的异常。这是我的代码,
I want to handle exception for both normal and rest/ajax requests. Here is my code,
@ControllerAdvice
public class MyExceptionHandler {
@ExceptionHandler(Exception.class)
public ModelAndView handleCustomException(Exception ex) {
ModelAndView model = new ModelAndView("error");
model.addObject("errMsg", ex.getMessage());
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
ex.printStackTrace(pw);
sw.toString();
model.addObject("errTrace", sw);
return model;
}
@ExceptionHandler(Exception.class)
@ResponseBody
public String handleAjaxException(Exception ex) {
JSONObject model = new JSONObject();
model.put("status", "error");
model.put("errMsg", ex.getMessage());
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
ex.printStackTrace(pw);
sw.toString();
model.put("errTrace", sw);
return model.toString();
}
}
这会给我一个错误,因为我无法使用@ ExceptionHandler(Exception.class)两次。那么解决方案是什么呢?
This will give me an error as I cant have @ExceptionHandler(Exception.class) twice. So what could be the solution?
推荐答案
请参阅@ControllerAdvice的配置:
see the configuration of @ControllerAdvice:http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/bind/annotation/ControllerAdvice.html
因此您可以创建两个类(错误处理程序)并指定注释/ basePackages / assignibaleTypes
So you can create two classes(error handlers) and specify annotations/basePackages/assignibaleTypes
例如,对于REST(ajax),对控制器使用@RestController注释,您可以处理如下错误:
For example for REST(ajax) use @RestController annotation for your controllers and you can handle errors like this:
@ControllerAdvice(annotations = RestController.class)
public class MyExceptionHandler {
@ExceptionHandler(Exception.class)
@ResponseBody
public String handleAjaxException(Exception ex) {
...
}
}
在其他情况下可能是错误处理程序wi注释
for other cases it can be error handler with annotation
@ControllerAdvice(annotations = Controller.class)
