#1 Created at ... [Delete] [Delete and Lock User] 
package Threads.Test11;public class ThreadLocalTests {
    public static void main(String[] args) {
        //测试ThreadLocal使用方法        
    ThreadLocal<String> studentName = new ThreadLocal<>();
    new Thread(()->{
            studentName.set("xiaoming");
            System.out.println(Thread.currentThread().getName()+"：学生姓名是-"+studentName.get());
            studentName.remove();
            System.out.println(Thread.currentThread().getName()+"：学生姓名是-"+studentName.get());
        }).start();
    new Thread(()->{
            studentName.set("xiaozhang");
            System.out.println(Thread.currentThread().getName()+"：学生姓名是-"+studentName.get());
        }).start();
    }
}


结果：
  Thread-0：学生姓名是-xiaoming
  Thread-0：学生姓名是-null
  Thread-1：学生姓名是-xiaozhang

  Process finished with exit code 0

#2 Created at ... [Delete] [Delete and Lock User]

例子只给了存储个String 按照php的说法就是个字符串， 那我想存储一个数组或者 对象 咋整。

😯

#3 Created at ... [Delete] [Delete and Lock User]

帮忙回复下二楼的兄弟。

将楼主的这一行 String

  ThreadLocal<String> studentName = new ThreadLocal

  替换为某个对象 例如User

  ThreadLocal<User> studentName = new ThreadLocal
