怎样定义全局异常处理器

新建一个类,加上注释两个

@ControllerAdvice(basePackages="com.example.controller")public class GlobalExceptionHandler {private static final Log log = LogFactory.get();//统一异常处理@ExceptionHandler,主要用于Exception@ExceptionHandler(Exception.class)@ResponseBody//返回json串public Result error(HttpServletRequest request, Exception e){log.error("异常信息:",e);return Result.error();}@ExceptionHandler(CustomException.class)@ResponseBody//返回json串public Result customError(HttpServletRequest request, CustomException e){return Result.error(e.getCode(), e.getMsg());}}
