简单更新已锁定

我们有一个非常简单的innodb数据库。只是一堆带外键的表，没有触发器之类的。
我们正在使用tomcat、spring和hibernate编写java应用程序。
当我们在这个表中执行非常简单的操作导致简单的更新时，更新会被卡住（锁定），所有其他请求都会因为这些锁定而超时。mysql的确切错误是： Lock wait timeout exceeded; try restarting transaction .
在mysql中，每个事务中总是有两个进程与这个锁相关：一个是 Updating ，另一个是 Sleeping . 我们觉得这有点奇怪，也许他们陷入僵局了？为什么？
当我们停止我们的应用程序，手动运行更新，它总是工作。所以这张table可能还可以。
hibernate是为autocommit事务配置的，因此在我们的应用程序中没有事务处理，所有事务都由hibernate处理。
我们尝试过：
更新hibernate
更新mysql（5.1到5.5）
正在将mysql配置更改为此。 SHOW INNODB STAUS :

保存对象（导致这些更新）的方法只是下面的代码，其余的是hibernate magic。

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;

@Service
@Repository("dbHome")
public class DbHome {
    @Autowired(required=true)
    private SessionFactory sessionFactory;

    // Other CRUD methods are here

    public void saveObject(final Object object) {
        final Session session = sessionFactory.getCurrentSession();
        session.saveOrUpdate(object);
    }
}

好的，多亏@m.deinum，我找到了解决办法。
首先，从hibernate配置中删除/注解以下行。

<property name="hibernate.current_session_context_class">thread</property>

然后，将以下行添加到spring上下文配置中。别忘了添加合适的名称空间，更多信息/例子在这里。

<tx:annotation-driven/>

还要确保你有 transactionManager 附近有豆子。
最后一步是添加 @Transactional 注解在后面（我阅读了它的导入以将其放置在后面） @Repository 注解。
