class MyThreadScopeData{//将类变成单例的private MyThreadScopeData(){}public static MyThreadScopeData getThreadInstance(){MyThreadScopeData instance = map.get();if(instance==null){instance = new MyThreadScopeData();map.set(instance);}return instance;}private static ThreadLocal map = new ThreadLocal();public void initSocket(){initSocket();}}
