Spring，Hibernate和Ehcache-错误的实体

[英]Spring, Hibernate and Ehcache - Wrong entities

原文 2010-05-27 13:13:54 5 1 java/ hibernate/ spring/ ehcache

I've got a webapp which uses spring+hibernate for my data layer. 我有一个使用spring + hibernate作为数据层的webapp。 I'm using 2nd level caching with ehcache as provider. 我正在使用ehcache作为提供程序的二级缓存。 Everything seems to work so far but sometimes we encounter a problem which I can't really figure out atm. 到目前为止，一切似乎都正常，但是有时我们遇到一个我无法真正解决atm的问题。

One of my tables is used for labels within the application - every user who logs access this table with his set language. 我的一个表用于应用程序中的标签-每个登录的用户都使用其设置的语言访问该表。 Works for 90% of the time. 90％的时间都可以工作。 But sometimes the user gets labels for the wrong language, eg instead of german everything turns to italian. 但是有时用户会得到错误语言的标签，例如，一切都变成意大利语，而不是德语。

After a logout and login all labels are correct. 注销并登录后，所有标签均正确。

Does anyone of you encountered something like this? 你们中有人遇到过这样的事情吗？ I'm not sure where to look at: spring+hibernate+ehcache is a solid package or is it not? 我不确定在哪里看：spring + hibernate + ehcache是一个可靠的软件包，不是吗？

Cheers 干杯

Spring/Hibernate/EhCache is a solid stack, I'm 99% sure it's a bug in your code. Spring / Hibernate / EhCache是一个可靠的堆栈，我99％确信这是您代码中的错误。

Any chance the labels are cached statically somewhere in your application? 标签是否有可能静态地缓存在应用程序中的某个位置？
