ThreadLocall

ThreadLocal是一个与线程绑定的变量。它与Synchronized一样，用于解决多线程并发访问的问题。 ThreadLocal可以在任何方法中轻松地获取到与当前线程绑定的对象。它的原理是通过ThreadLocal类的set()方法，可以将变量与当前线程关联起来，并存储在ThreadLocalMap中。如果当前线程已经有ThreadLocalMap，那么直接更新要保存的变量值；否则，创建ThreadLocalMap并存储变量值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
