使用代码获取执行的dataSendMQTaskExecutor的ThreadPoolTaskExecutor

可以使用Java中的反射机制来获取执行的dataSendMQTaskExecutor的ThreadPoolTaskExecutor。具体实现如下所示：

import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.util.ReflectionUtils;

// 获取dataSendMQTaskExecutor的ThreadPoolTaskExecutor
ThreadPoolTaskExecutor executor = null;
Object taskExecutor = ReflectionUtils.getField(ReflectionUtils.findField(DataSendMQTask.class, "taskExecutor"), dataSendMQTask);
if (taskExecutor instanceof ThreadPoolTaskExecutor) {
    executor = (ThreadPoolTaskExecutor) taskExecutor;
}

其中，`DataSendMQTask`是包含`dataSendMQTaskExecutor`的类，`dataSendMQTask`是`DataSendMQTask`的实例。上述代码中，通过`ReflectionUtils.findField`方法获取`DataSendMQTask`类中名为`taskExecutor`的字段，再通过`ReflectionUtils.getField`方法获取该字段的值，最后判断该值是否为`ThreadPoolTaskExecutor`类型，如果是则强制转换为`ThreadPoolTaskExecutor`类型并赋值给`executor`变量。
