Hibernate session.beginTransaction()调用和Mysql启动事务 [英] Hibernate session.beginTransaction() call and Mysql Start Transaction

问题描述

当我发出命令时

session.beginTransaction();
// do something
session.getTransaction().commit();

我的数据库没有看到相应的启动事务"命令问题.任何人都可以解释为什么它不存在以及mysql如何知道事务的边界.

I don't see a corresponding Start Transaction command issue to my database. Can any body explain to why it is not there and how mysql knows the boundary of a transaction.

谢谢

推荐答案

如 Java JDBC教程提到了禁用自动提交模式以便能够将两个或多个语句组合到一个事务中.这正是Hibernate在session.beginTransaction()调用中所做的.

As briefly mentioned in the Hibernate Developer Guide, JDBC does not define an explicit method for beginning a transaction. The Java JDBC Tutorial mentions disabling auto-commit mode to be able to group two or more statements into a transaction. This is exactly what Hibernate does in the session.beginTransaction() call.
