Java 播放2.5-@事务性只读被忽略？

我有一个Java Play 2.5应用程序，我有一个标记为只读的事务（在控制器级别）：

（这是play.db.jpa.Transactional注释）

因此，如果我打开hibernate事务的日志记录：

 <logger name="org.hibernate.engine.transaction" level="TRACE"/>

然而，我有一个问题-它不是只读的！我添加了一些修改对象的代码（obj.setField（“changed value”）），并在事务结束时将其保存到数据库中

我期待一个异常，告诉我事务是只读的，无法提交

为什么事务不是只读的

我是否可以在日志中看到Hibernate是否创建了只读事务

---

其他信息：Java Play 2.5.10、Hibernate 5（5.2.6）和PostgreSQL作为DB。

因此，这似乎是因为控制器类本身用@Transactional注释，方法用@Transactional（readOnly=true）注释

不知何故，类注释覆盖了方法注释。在我看来，这似乎不符合逻辑，但在实践中，情况似乎是这样的：一旦我从类级别删除了@Transactional，它就工作得很好

 <logger name="org.hibernate.engine.transaction" level="TRACE"/>
