如何在TaskDecorator中使用ThreadLocalTargetSource？

如何解决如何在TaskDecorator中使用ThreadLocalTargetSource？

我们正在使用Spring的ThreadLocalTargetSource将一些Tenant上下文信息设置到bean中，并通过典型的HTTP请求或接收到的事件来传播它。该方法类似于以下内容中的描述：

https://dzone.com/articles/an-alternative-approach-to-threadlocal-using-sprin-1

@Bean(destroyMethod = "destroy")
public ThreadLocalTargetSource threadLocalTenantContext() {
    ThreadLocalTargetSource result = new ThreadLocalTargetSource();
    result.setTargetBeanName("tenantContext");
    return result;
}

@Primary
@Bean(name = "proxiedThreadLocalTargetSource")
public Proxyfactorybean proxiedThreadLocalTargetSource(ThreadLocalTargetSource threadLocalTargetSource) {
    Proxyfactorybean result = new Proxyfactorybean();
    result.setTargetSource(threadLocalTargetSource);
    return result;
}

但是，我现在需要使用TaskExecutor异步运行某些进程，并且我不确定如何将租户信息发送到新产生的线程中。使用TaskDecorator可以很容易地将信息从MDC获取到新线程中：

// Set this in taskExecutor.setDecorator(...)
public class TenantContextThreadDecorator implements TaskDecorator {

    @Override
    public Runnable decorate(Runnable runnable) {
        final Map<String,String> mdc = MDC.getcopyOfContextMap();
        return () -> {
            try {
                MDC.setContextMap(mdc);
                runnable.run();
            } finally {
                MDC.clear();
            }
        };
    }
}

但是我不知道如何让TenantContext在可运行对象上进行设置。
