我目前正在开发一个 Spring MVC 应用程序。我已经配置了一个 JDBC TransactionManager，并且我正在使用 AOP XML 进行声明性事务管理。但是，即使我将方法配置为在只读 = true 上运行，它仍然会提交事务。

如何防止自动提交？我还注意到，即使我不放任何事务管理代码，代码仍然会提交。请注意，事务建议是在我为 RuntimeException 放置 no-rollback-for 然后执行 1/0 时调用的，如果我放置与 rollback-for 相同的内容，它会正确提交数据并回滚。我还通过将线程置于睡眠状态来尝试查询超时，即使这样也不起作用，但我认为超时可能是针对实际查询的，所以没关系。提前致谢！
