请帮忙。我花了一整天时间尝试所有类似问题的答案,但没有运气。 我只需要将对象保存在数据库中。 persist()没有保存任何东西,persist()+ flush()抛出异常javax.persistence.TransactionRequiredException:没有事务正在进行中。

编辑:我更改了组件扫描基础包,只保留了servlet-context.xml中的控制器,其余部分保存在root-context.xml中,但现在它说org.springframework.web.context.ContextLoader - 上下文初始化失败并且无法创建GoodDao.class ..

问题出在maven依赖项上。不同版本的hibernate混乱不堪。我使用&#34; mvn依赖项查找了项目依赖项的层次结构:tree -Dverbose&#34;并使用适当的版本设置适当的依赖项。
