Answer 1

这看起来像你选择的Spring Framework 4.3.0.RELEASE版本的Jar冲突。请将其降级为hibernate-core-5.1.0.Final.jar。

Answer 2

这看起来很奇怪，因为在Spring Framework 4.3.0.RELEASE中添加了Hibernate 5.2 API的方法签名支持，它首先专门查找getHibernateFlushMode，然后由getFlushMode跟进。

我说你可能在类路径上有新的Hibernate库，但是你可能在类路径中有一个不兼容的旧版Spring Framework。

Answer 3

我发现了实现该方法的类ConfigurationHelper public static getFlushMode( Object value ) 在包org.hibernate.jpa.internal.util中的hibernate-entitymanager-5.0.2.Final.jar中，与正确的方法签名冲突，该签名包括在hibernate-core-5.2.12.Final.jar中实现的默认值。错误的实施得到了解决。我从我的gradle.build文件中删除了依赖hibernate-entitymanager-5.0.2.Final.jar，该文件已经包含了依赖hibernate-core-5.2.12.Final.jar并且整理了找不到异常的方法

迁移到hibernate核心5.2.1 ava.lang.NoSuchMethodError：org.hibernate.Session.getFlushMode（）Lorg / hibernate / FlushMode;
