Spring integration 在spring集成中使用服务激活器轮询器，如何在线程池中传递MCD（slf4j）上下文

有谁能建议我如何将MCD上下文传递给服务serviceName的方法吗？

答案是对将在该TaskExecutor上执行的Runnable进行解码

互联网上有很多关于此事的文章：

此外，Spring Security还提供了一些解决方案，用于将SecurityContext从一个线程传播到另一个线程：

我建议您从这些链接中获得一些想法，并使用ThreadPoolTaskExecutor中现有的API：

因此，您的装饰程序应该有如下代码：

/**
 * Specify a custom {@link TaskDecorator} to be applied to any {@link Runnable}
 * about to be executed.
 * <p>Note that such a decorator is not necessarily being applied to the
 * user-supplied {@code Runnable}/{@code Callable} but rather to the actual
 * execution callback (which may be a wrapper around the user-supplied task).
 * <p>The primary use case is to set some execution context around the task's
 * invocation, or to provide some monitoring/statistics for task execution.
 * @since 4.3
 */
public void setTaskDecorator(TaskDecorator taskDecorator) {

/**

public void setTaskDecorator(TaskDecorator taskDecorator) {

taskExecutor.setTaskDecorator(runnable -> {
        Map<String, String> mdc = MDC.getCopyOfContextMap();
        return () -> {
            MDC.setContextMap(mdc);
            runnable.run();
        };
    });
