Spring启动JPA休眠+ persistence.xml不插入

Question

我遇到插入无法正常工作的问题。读取（选择）工作正常。但是，在我的@Transactional方法结束时没有执行插入操作。即使我看到实体管理器上正在调用事务提交/关闭。我尝试了不同的配置，但仍然无法在事务结束时获取记录（插入）。我没有看到任何错误正在产生。我启用了hibernate.transaction DEBUG，并且没有看到任何hibernate事务消息。

我正在使用Tomcat作为WAR可执行文件运行Spring引导（.1.5.3）。我在Spring Boot中使用persistence.xml（hibernate5-ddl-maven-plugin <需要在生成过程中生成SQL DDL）。在调试时，我看到JpaTransactionManager创建新的事务（使用name创建新事务...打开新的EntityManager ,,,将JPA事务公开为JDBC事务），加入其他@Transactional方法（找到线程绑定的EntityManager ..参与现有事务）并提交TX（Initiating transaction commit ...在EntityManager上提交JPA事务），并关闭JPA EM（关闭JPA EntityManager）。这一切都根据@Transactional规范进行。但是，该记录未插入到数据库中。我没有看到任何休眠事务消息。

下面是我的一些配置。

的persistence.xml：

<persistence version="2.1" 
     xmlns="http://xmlns.jcp.org/xml/ns/persistence" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

Answer 1

宾果!!!! 我用@PersistenceContext注释了我的EntityManager（unitName = PERSISTENCE_UNIT_NAME）。之后，它的作品。

下面是修复上述问题的代码。注意下面的@PersistenceContext注解（这是解决问题的方法）。在我进行@Inject注解之前。

@PersistenceContext(unitName = PERSISTENCE_UNIT_NAME) 
protected EntityManager em;
