Runnable里面32313133353236313431303231363533e4b893e5b19e31333363386230没有传参函数，所以得自己造一个
0.自定义一个接口，继承Runnable，新增一个传参方法public interface MyRunnable extends Runnable{
public MyRunnable setParam(String... param);
}实现这个自定义接口MyRunnable sendMessage = new MyRunnable() {
String message;
@Override
public MyRunnable setParam(String... param) {
message = param[0];
return this;
}
@Override
public void run() {
sendMessage(message);
}
};
2.初始化线程池，运行RunnableExecutorService cachedThreadPool = Executors.newCachedThreadPool();
cachedThreadPool.execute(sendMessage.setParam("I am service"));
如上所示，线程池调用的一个runnable实例，这个runnable实例传入了一个字符串参数
