RestControllerAdvice 全局异常处理

//返回的json格式数据

1：RestControllerAdvice 注解，可以用于定义@ExceptionHandler、@InitBinder、@ModelAttribute，并应用到所有@RequestMapping、@PostMapping， @GetMapping注解中

@RestControllerAdvice(basePackages ="com.zsc.tbpractice.controller" )
public class GlobalExceptionHandler {

    private Log logger = LogFactory.getLog(GlobalExceptionHandler.class);

2：ExceptionHandler 标记为全局异常

    @ExceptionHandler(value = Exception.class)
    public JsonResult defaultErrorHandler(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
        response.setContentType(MediaType.APPLICATION_JSON_UTF8_VALUE);
        String url = request.getRequestURI() + (StringUtil.isNotEmpty(request.getQueryString()) ? ("?" + request.getQueryString()) : "");
        JsonResult result = new JsonResult(false);
        result.setRet(500);
        result.setMsg("error");
        if (ex instanceof TokenException) {
            result.setMsg(ex.getMessage());
        } else if (ex instanceof SysException) {
            result.setRet(((SysException) ex).getErrorCode());
            result.setMsg(ex.getMessage());
        } else if (ex instanceof NoHandlerFoundException) {
            NoHandlerFoundException notFindEx = (NoHandlerFoundException)ex;
            result.setRet(404);
            result.setMsg("找不到该接口: "+ JsonUtils.toStringNoEx(notFindEx));
        } else if (ex instanceof org.springframework.web.HttpRequestMethodNotSupportedException) {
            result.setRet(403);
            result.setMsg("不支持该请求方式");
        } else {
            result.setMsg("对不起！服务器趴窝了！" + ex.getClass().getName()+">>>>"+ex.getMessage());
            ex.printStackTrace();
        }
        logger.error("运行异常: "+result.getMsg());
        return result;
    }
}
