LazyInitializationException：无法初始化代理-Spring和Hibernate中没有会话

Question

我收到此错误：我的Web应用程序中出现“ org.hibernate.LazyInitializationException：无法初始化代理-没有会话”的错误。 我使用Spring和Hibernate，并使用“ sessionFactory.getCurrentSession（）”执行查询。

我读到了很多有关此问题的内容，因此尝试了找到的答案，但没有用。 我目前正在使用“ OpenSessionInViewFilter”和“ OpenSessionInViewInterceptor”。

我附上我的配置文件。

先感谢您。

Answer 1

看起来您正在启动线程（stacktrace很短，没有任何servlet处理代码，并以run -method开头），然后操作了由休眠加载的对象。 由于休眠将其会话与执行线程相关联，因此它找不到与您启动的线程相关联的会话。

你应该：

无法启动新线程。 要么
将对象加载到操作它们的线程中（仅将ID从一个线程传递到另一个线程，而不是将对象传递）。 要么
在将对象传递到操纵它们的线程之前，请完全加载它们。
