概念
threadlocal为每一个线程提供一个单独的存储空间,具有线程隔离的作用,只有在线程内才能获取到对应的值,线程外则不能访问
工具类
public class BaseContext {
public static ThreadLocal threadLocal = new ThreadLocal();
public static void setCurrentId(Long id) {
threadLocal.set(id);
}
public static Long getCurrentId() {
return threadLocal.get();
}
public static void removeCurrentId() {
threadLocal.remove();
}
}
