public class TenantTest {

    public static void main(String[] args) {
        //变量
        TenantInfo tenantInfo = new TenantInfo();
        tenantInfo.setCode("shibei");

        //变量可父子线程传递
        InheritableThreadLocal<TenantInfo> t1 = new InheritableThreadLocal<>();
        t1.set(tenantInfo);

        //变量无法父子线程传递
        ThreadLocal<TenantInfo> t2 = new ThreadLocal<>();
        t2.set(tenantInfo);

        new Thread(() -> {
            System.out.println(t1.get());
            System.out.println(t2.get());
