出现异常:
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());
}
}
