最近用springboot,spring-boot-starter-data-jpa(jpa包含了hibernate)配置一个框架遇到很多问题：
1，错误：
Could not obtain transaction-synchronized Session for current thread
解决方法：
在DAO实现层添加：
@Transactional @EnableTransactionManagement sessionFactory.getCurrentSession();//必须在这类中加上特性标签 @Transactional @EnableTransactionManagement
参考别人的：Spring Hibernate - Could not obtain transaction-synchronized Session for current thread - Stack Overflow
2，错误：
org.springframework.orm.hibernate5. HibernateSystemException: Could not obtain transaction-synchronized Session for current thread; nested exception is org.hibernate.HibernateException:
解决方法（jpa和）：
在application.properties文件添加：
spring.jpa.open-in-view=false
参考别人：java - ClassCastException: org.springframework.orm.jpa.EntityManagerHolder cannot be cast to org.springframework.orm.hibernate5.SessionHolder - Stack Overflow
