以下是配置MDC，非必须，skywalking记录的是tid
@Bean
public FilterRegistrationBean indexEsgFilter() {
FilterRegistrationBean registration = new FilterRegistrationBean(new TraceIdFilter());
return registration;
}
public class TraceIdFilter implements Filter {
private static final String UNIQUE_ID = "traceIdxmh";
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
String traceId = httpServletRequest.getHeader(UNIQUE_ID);
if (StrUtil.isBlank(traceId)) {
traceId = UUID.randomUUID().toString().replace("-", "");
}
// 将traceId放入MDC中，这样我们就可以在日志中打印出来了。
System.out.println("TraceIdFilter.doFilter" + traceId);
MDC.put(UNIQUE_ID, traceId);
try {
chain.doFilter(request, response);
} finally {
MDC.remove(UNIQUE_ID);
}
}
