执行了一条sql ，说明第二次从ehcache里面拿到的，

Hibernate: select users0_.id as id1_0_0_, users0_.address as address2_0_0_, users0_.age as age3_0_0_, users0_.name as name4_0_0_ from t_users users0_ where users0_.id=?
Users [id=1, name=hello, age=34, address=shanghai]
Users [id=1, name=hello, age=34, address=shanghai]
