ThreadLocal<Long>

ThreadLocal<Long>是一个泛型类，用于在每个线程中创建一个独立的Long类型的变量副本。每个Thread线程内部都有一个ThreadLocalMap，ThreadLocal负责向map获取和设置线程的变量值。ThreadLocalMap是ThreadLocal的一个静态内部类，存储着ThreadLocal实例作为键值和对应线程的变量副本作为值。可以通过ThreadLocal的get()方法获取当前线程的变量副本，set()方法设置当前线程的变量副本，remove()方法移除当前线程的变量副本。在使用ThreadLocal时，每个线程都会有自己独立的变量副本，互相之间不会产生影响。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
