SqlSession was not registered for synchronization because synchronization is not JDBC Connection

这是一个来自 Spring 框架的警告信息，提示当前的事务管理器未注册一个用于 JDBC 连接的 SqlSession。可能会影响到事务的正确性。

这个问题通常发生在使用 MyBatis 持久层框架时，需要在 Spring 配置文件中添加如下代码：

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  <property name="dataSource" ref="dataSource" />
</bean>

<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
  <constructor-arg ref="sqlSessionFactory" />
</bean>

was not registered for synchronization because synchronization is not active JDBC Connection

这段引用中的句子是在描述一个错误信息，即"SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@19e35973] was not registered for synchronization because synchronization is not active JDBC Connection [com.mchange.v2.c3p0.impl.NewProxyConnection@7b51e83e] will not be managed by Spring"。这个错误信息的意思是SqlSession没有被注册为同步的，因为同步未激活，所以JDBC Connection也不能被Spring所托管。这可能是因为在代码中未正确配置或激活同步机制导致的。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

问题:sqlsession was not registered for synchronization是什么意思?
回答: 当出现"sqlsession was not registered for synchronization"的错误信息时，意味着在当前的上下文中，没有为SqlSession注册事务同步。这通常是因为没有启用事务管理或者事务同步未激活所导致的。在这种情况下，JDBC连接也不会被Spring管理。\[1\]这个问题通常出现在整合Spring和MyBatis的项目中，可能是由于配置错误或者缺少必要的事务管理器所引起的。如果你想要解决这个问题，你可以检查你的项目配置，确保正确配置了事务管理器，并且在需要的地方启用了事务。\[1\]\[3\]
