相当于全局变量

//全局变量 全局共享变量
public class ThreadLocalUtils {private static ThreadLocal THREAD_LOCAL = new ThreadLocal();
//    根据键值对取值public static <T> T get() {return (T)THREAD_LOCAL.get();}
//    存储键值对public static void set(Object o) {THREAD_LOCAL.set(o);}
//    清除 防止内存泄露public static void remove() {THREAD_LOCAL.remove();}

// 根据用户名查询@Select("select * from users where username=#{username}")Users findByUserName(String username);//    添加注册
