Spring Filter優化日誌

Filter chase

將處理請求的線程，更名爲隨機名稱，即可知道該HTTP請求對應的線程的所有同步操作的日誌，便於排查問題

Spring Filter

WebFilter，過濾所有url

@Component
@WebFilter(urlPatterns = "/*", filterName = "controllerFilter")
public class ControllerFilter implements Filter {
    protected Logger logger = LoggerFactory.getLogger(ControllerFilter.class);

    private static List<String> ignoreUri = Lists.newArrayList();

    @Override
    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws ServletException, IOException {
        MetricsStopWatch metricsStopWatch = MetricsStopWatch.startServerWatch();

        Thread thread = Thread.currentThread();
        String oldName = thread.getName();

        HttpServletRequest httpServletRequest = (HttpServletRequest) req;
        String servletPath = httpServletRequest.getServletPath();
        boolean isIgnore = false;
        for (String s : ignoreUri) {
            if (servletPath.contains(s)){
                isIgnore = true;
                break;
            }
        }
        try {
            String randomId = RandomStringUtils.randomAlphanumeric(10);
            thread.setName(servletPath + "-" + randomId);
            if (!isIgnore){
                logger.info("請求:{}", servletPath);
            }
            chain.doFilter(req, resp);
        } finally {
            metricsStopWatch.code(0).uri(servletPath.replaceAll("/", "_")).markDurationAndCode();
            if (!isIgnore) {
                logger.info("響應url:{}, time: {} ms", servletPath, metricsStopWatch.getTime());
            }
            thread.setName(oldName);
        }
    }

    @Override
    public void init(FilterConfig config) throws ServletException {}

    @Override
    public void destroy() {}
}

返回示例
