由于我使用了lombok，所以可以通过@Slf4j获取到一个log对象。JSONResult可以通过普通的map集合代替。
package com.xxx.xxxx.controller;
import com.xxx.xxxx.pojo.JSONResult;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
/**
* @Description: 全局捕捉异常
*/
@Slf4j
@RestControllerAdvice("com.xxx.xxxx.controller")
public class GlobalExceptionHandler {
// 设置一个错误页面
private static final String ERROR_VIEW = "error";
@ExceptionHandler(value = Exception.class)
public Object errorHandler(HttpServletRequest request, Exception e) {
log.error("url: " + request.getRequestURL() + " -> exception: " + e.getMessage());
if (isAjax(request)) {
return JSONResult.errorException(e.getMessage());
} else {
ModelAndView mav = new ModelAndView();
mav.addObject("exception", e);
mav.addObject("url", request.getRequestURL());
mav.setViewName(ERROR_VIEW);
return mav;
}
}
/**
* @Description: 判断是否是ajax请求
*/
private static boolean isAjax(HttpServletRequest httpRequest) {
return (httpRequest.getHeader("X-Requested-With") != null &&
"XMLHttpRequest".equals(httpRequest.getHeader("X-Requested-With")));
}
}
