错误：“另一个未命名的CacheManager已存在于同一个VM中”使用Spring，Jersey和ehCache

时间：2012-10-10 15:57:47

标签： java spring jersey ehcache

似乎还有另一个加载缓存的进程，但无法找到它（如果错误没有告诉我说谎的话）。它告诉我的唯一一件事就是我从一个名为 InputStreamConfigurationSource 的类

中启动了另一个缓存。

有没有人遇到这个错误???

我正在使用

  • 春季3
  • 泽西岛1.6 / 1.7
  • ehCache 2.6

与此问题一样“Jersey @InjectParam creating a new Object instead of taking from Spring”正在使用错误的servlet。所以有两个容器启动，一个用于Spring，通过“ ContextLoaderListener ”，一个用于Jersey通过“ ServletContainer ”。这意味着正在启动两个缓存实例。

使用的Servlet容器应该是

 <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>

所以泽西可以附加到Spring容器
