spring.data.jap调用接口时实际上做了些啥
通过AOP调用 org.springframework.data.jpa.repository.support.SimpleJpaRepository
AOP需要经过如下interceptor
[org.springframework.aop.interceptor.ExposeInvocationInterceptor,?
INSTANCE, (class org.springframework.data.jpa.repository.support.LockModeRepositoryPostProcessor$LockModePopulatingMethodIntercceptor)
org.springframework.dao.support.PersistenceExceptionTranslationInterceptor,?
org.springframework.transaction.interceptor.TransactionInterceptor,?
org.springframework.data.repository.core.support.RepositoryFactorySupport$QueryExecutorMethodInterceptor,?
org.springframework.dao.support.PersistenceExceptionTranslationInterceptor]
