映射诊断上下文（MDC）与SLF4J登录jboss / wildfly 10它已被清除

Question

我将我的Web应用程序配置为以这种方式使用MDC：

    MDC.put("cliente", "TEST");
    org.slf4j.MDC.put("cliente2", "TEST2");

进入javax.ws.rs.core.Application启动类

import org.jboss.logging.MDC;

@ApplicationPath("/api")
public class ApplicationResource extends Application {

    public ApplicationResource(){
        MDC.put("cliente", "TEST");
        org.slf4j.MDC.put("cliente2", "TEST2");
    }

日志中的结果是：

为什么我的MDC被清除了？有必要在另一个地方申报吗？

Answer 1

MDC或映射诊断上下文基于本地线程。那些其他消息是从其他线程写入的，因此不为这些消息设置MDC值。
