需要再全局異常處理類中實現HandlerExceptionResolver 接口?

package com.learn.exception;import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.HandlerExceptionResolver; import org.springframework.web.servlet.ModelAndView;/*** 通過實現HandlerExceptionResolver接口做全局異常處理***/ @Configuration public class GlobalException implements HandlerExceptionResolver {@Overridepublic ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler,Exception ex) {ModelAndView mv = new ModelAndView();// 判斷不同異常類型，做不同視圖跳轉if(ex instanceof ArithmeticException){mv.setViewName("error1");}if(ex instanceof NullPointerException){mv.setViewName("error2");}mv.addObject("error", ex.toString());return mv;} }

?
