Executing an "update" query outside of a transaction using the code below was possible in Hibernate 5.1: Raw entityManager.createNativeQuery("delete from Employee").executeUpdate(); After moving from JBoss EAP 7.1 / Hibernate 5.1 to JBoss EAP 7.2 / Hibernate 5.3, encountering the failure below:...
持久化上下文(Persist Context)就是一个受管的Entity实例的集合。 每一个持久化上下文都关联一个持久化单元,持久化上下文不可能脱离持久化单元独立存在。 持久化上下文是一个动态概念。 尽管持久化上下文非常重要,但是开发者不直接与之打交道,持久化上下文在程序中是透明的,我们通过EntityManager间接管理它。
Persistence—the ability of data to outlive an instance of a program—is central to modern applications. Hibernate, the most popular Java persistence tool, provides automatic and transparent object/relational mapping so it's a snap to work with SQL databases in Java applications. Hibernate conforms...
