Java org.apache.ibatis.executor.executor异常：无法提交，事务已关闭-批插入时

我想使用MyBatis（3.5.1）将批插入到PostgreSQL中。当我在sqlSession上提交时，我得到一个异常org.apache.ibatis.executor.ExecutorException:无法提交，事务已经关闭

虽然逐个插入记录可以正常工作

我在自动提交标志设置为false的情况下创建SqlSession

mapper.xml

<insert id="saveAll" parameterType="com.test.Event"
            useGeneratedKeys="true" keyProperty="id" keyColumn="id">
        INSERT INTO test.events (device_id, user_name)
        VALUES
        <foreach collection="events" item="event" separator=",">
            (#{event.deviceId}, #{event.username})
        </foreach>
</insert>

堆栈跟踪

有解决办法吗

谢谢

您的

saveAll

方法关闭

SqlSession

并结束事务

此语句在try块后调用SqlSession.close`

try (SqlSession sqlSession = transactionManager.getSession()) {
    EventMapper mapper = sqlSession.getMapper(EventMapper.class);
    mapper.saveAll(events);
}

为了解决这个问题，首先需要确保使用相同的

SqlSession

。根据

transactionManager.getSession

的具体操作，它可能返回与调用

存储库.saveAll的代码中的
SqlSession
不同的

修复此问题并使用相同会话后，需要删除
try
块，以便会话不会自动关闭
