javaWeb ThreadLocal-已阅

当然局部变量也能避免争抢，但局部变量作用范围仅在当前方法，ThreadLocal可以实现线程内的资源共享。

 

应用案例：

public class WmThreadLocalUtil {

    private final static ThreadLocal<WmUser> WM_USER_THREAD_LOCAL = new ThreadLocal<>();

    //存入线程中
    public static void setUser(WmUser wmUser){
        WM_USER_THREAD_LOCAL.set(wmUser);
    }

    //从线程中获取
    public static WmUser getUser(){
        return WM_USER_THREAD_LOCAL.get();
    }

    //清理
    public static void clear(){
        WM_USER_THREAD_LOCAL.remove();
    }

}
