[Java知识库]Could not obtain transaction-synchronized Session for current thread

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
