Spring Web 拦截异常, 封装返回结果并记录入参

异常拦截类

@ControllerAdvice("com.test.xxxx") @ResponseBody public class GlobalExceptionHandler { // 拦截 ServiceException 异常，并封装返回结果 @ExceptionHandler(ServiceException.class) public BaseResponse serviceExceptionHandler(HttpServletResponse response, ServiceException ex , ServletRequest request) { response.setStatus(200); // 自定义的类 LogInfoHandler.LogServiceException(ex, request,logger); return new BaseResponse(ex.getStatus(), ex.getMessage()); } }

Request缓存类

// 缓存request请求的InputStream,否则记录传参时直接获取body流会出现 java.io.IOException: Stream closed 错误 @Component public class RequestWrapperFilter extends OncePerRequestFilter { @Override protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException { filterChain.doFilter(new ContentCachingRequestWrapper(httpServletRequest), httpServletResponse); } }

参数日志记录类

public class LogInfoHandler { public static void LogServiceException(ServiceException ex, ServletRequest request, Logger log) { try { LogInfo logInfo = new LogInfo(); // 记录错误信息和抛出的代码位置 if (ex.getStackTrace() != null && ex.getStackTrace().length > 0) { logInfo.setErrorMsg(ex.getLocalizedMessage() + "\n" + ex.getStackTrace()[0].toString()); } else { logInfo.setErrorMsg(ex.getLocalizedMessage()); } // 获取接口所有的参数 if (request != null && request instanceof ContentCachingRequestWrapper) { NativeWebRequest webRequest = new ServletWebRequest((HttpServletRequest) request); // 获取路由里的参数 Map<String, String> pathVariables = (Map<String, String>) webRequest.getAttribute(HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE, RequestAttributes.SCOPE_REQUEST); // 获取路径后面跟的参数 Map<String, String[]> parameterMaps = request.getParameterMap(); ContentCachingRequestWrapper wrapper = (ContentCachingRequestWrapper) request; // 获取body里的参数 String requestBody = StringUtils.toEncodedString(wrapper.getContentAsByteArray(), Charset.forName(wrapper.getCharacterEncoding())); logInfo.setParameterMaps(JSON.toJSONString(parameterMaps)); logInfo.setPathVariables(JSON.toJSONString(pathVariables)); logInfo.setRequestBody(requestBody); } // 是否打印出所有的堆栈信息 if(ex.isStackLog()) { log.error(JSON.toJSONString(logInfo),ex); } else { log.error(JSON.toJSONString(logInfo)); } }catch (Exception e) { log.error("LogServiceException 异常", e); log.error(ex.getMessage(),ex); } } @Data private static class LogInfo { private String errorMsg; private String pathVariables; private String parameterMaps; private String requestBody; } }
