java - Hibernate、Spring - 事务

Question

我在 Spring 中有一个项目，其中有 2 个到数据库的连接。两个，因为一个用于只读连接，另一个用于读写连接。

我的问题是，当我尝试调用只读方法时，我得到:

没有 Hibernate Session 绑定(bind)到线程，并且配置不允许在此处创建非事务性 session

现在我不知道如何准确配置我的连接。

下面我插入了我的服务类文件。问题是当我尝试使用 sessionFactory 调用方法时，当我使用 sessionFactory 时 - 一切正常。

我的配置是:

hibernate-context.xml:

        <url-pattern>/*</url-pattern>
      </filter-mapping>

在我的 web.xml 中。

根据您的建议，如果我将 @Transactional("transactionManagerr") 添加到我的方法中 - 它不会改变任何内容，我仍然会收到错误。

Answer 1

我认为您必须在 @Transactional 中指定事务管理器名称(例如 @Transactional("transactionManagerr"))注释。读 Documentation和 Jira
