SpringBoot 日志配置和请求TraceId设置

发表于

摘要：该实例主要是基于slf4j的MDC进行实现tranceId的上下文保存，当然也可以自己定义ThreadLocal进行保存，方式一直，对于跨服务的调用也可以把tranceId放在请求头中，接收方复用该tranceId

基于Filter的实现

拦截所有的请求

scala复制代码@WebFilter(filterName = "traceIdFilter", urlPatterns = "/*")
@Component
public class TraceFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
        MDC.put("tranceId", UUID.randomUUID().toString());
        filterChain.doFilter(httpServletRequest,httpServletResponse);
    }

}
