Week2 （July 7-July 14）

Weekly summary： 1.Studied the casbin policy. 2.Added HibernateAdapter for jCasbin.

Before coding： I haven't used Hibernate, but after consulting the data, I found that the use of Hibernate is similar to the Mybatis framework that I used, and MybatisAdapter already has relevant implementation, so I refer to the code of MybatisAdapter to write HibernateAdapter.

Next week： 1.Continue writing adapters that have not yet been implemented.
