- 线上bug异常捕捉

- 背景：上线的时候发现一个bug，参数类型定义是一个Long型，但是前端传递过来的参数是一个undefined，导致解析失败。但是查看日志打印只显示类型转换错误(MethodArgumentTypeMismatchException)，也不清楚调的是哪个接口.于是调整了一下日志捕捉代码。

@ExceptionHandler(MissingServletRequestParameterException.class)
    public ResponseData<Object> paramErrorHandler(MissingServletRequestParameterException e, HttpServletRequest request) {
        log(e, request);
        return ResponseData.fail(ResponseCode.PARAM_INVALIDATE.getCode(), e.getMessage());
    }

    @ExceptionHandler(MethodArgumentTypeMismatchException.class)
    public ResponseData<Object> mismatchErrorHandler(MethodArgumentTypeMismatchException e, HttpServletRequest request) {
        log.error("方法:{},字段:{},参数:{},错误信息:{}", e.getParameter().getMethod(), e.getName(), e.getValue(), e.getMessage());
        return ResponseData.fail(ResponseCode.PARAM_INVALIDATE.getCode(), e.getMessage());
    }

    @ExceptionHandler(BusinessException.class)
    public ResponseData<Object> handler(BusinessException e) {
        log.error("业务异常:{}", (Object) e);
        return ResponseData.fail(e.getCode() == null ? ResponseCode.INTERNAL_ERROR.getCode() : e.getCode(), e.getMsg());
    }

    @ExceptionHandler(ParamException.class)
    public ResponseData<Object> handler(ParamException e) {
        log.error("参数异常:{}", (Object) e);
        return ResponseData.fail(ResponseCode.PARAM_INVALIDATE.getCode(), e.getMsg());
    }

    @ExceptionHandler
    public ResponseData<Object> handler(Exception e, HttpServletRequest request) {
        // Exception 打印最全信息
        log(e, request);
        return ResponseData.fail(ResponseCode.INTERNAL_ERROR.getCode(), IcebergConstant.ERROR_MSG_EXCEPTION);
    }

    private void log(Exception e, HttpServletRequest request) {
        log.error("ipAddress->{}", getIpAddress(request));
        log.error("url->{}", request.getRequestURL());
        log.error("error->{}", (Object) e);
    }

    public String getIpAddress(HttpServletRequest request) {
        String ip = request.getHeader("x-forwarded-for");
        String unknown = "unknown";
        if (ip == null || ip.length() == 0 || unknown.equalsIgnoreCase(ip)) {
            ip = request.getHeader("Proxy-Client-IP");
        }
        if (ip == null || ip.length() == 0 || unknown.equalsIgnoreCase(ip)) {
            ip = request.getHeader("WL-Proxy-Client-IP");
        }
        if (ip == null || ip.length() == 0 || unknown.equalsIgnoreCase(ip)) {
            ip = request.getHeader("HTTP_CLIENT_IP");
        }
        if (ip == null || ip.length() == 0 || unknown.equalsIgnoreCase(ip)) {
            ip = request.getHeader("HTTP_X_FORWARDED_FOR");
        }
        if (ip == null || ip.length() == 0 || unknown.equalsIgnoreCase(ip)) {
            ip = request.getRemoteAddr();
        }
        return ip;
    }
