【问题描述】：
我一直致力于将应用程序从 Spring 3 升级到 4 和 Hibernate 3 到 4。现在的确切版本： 弹簧：4.1.9 休眠：4.3.7
由于依赖关系，我还必须升级 Junit 版本，我们现在使用的是 4.12。
自从升级以来，我在大多数单元测试中都遇到了 java 堆空间异常：

我尝试过在线搜索，但没有找到任何解决方案。
请让我知道我需要发布的任何配置文件。
【问题讨论】：
-
正在使用哪个版本的 ehcache？我会更新以使用最新的 2.x 版本。那么，你有
ehcache.xml文件吗？ -
我使用的是 ehcache 2.5。目前无法访问办公室笔记本电脑。所以将尽快共享文件
