似乎有另一个进程正在加载缓存，但无法找到它（如果错误没有告诉我撒谎）。它唯一告诉我的是，我从一个名为InputStreamConfigurationSource的类的某个地方开始了另一个缓存？？？

有没有人遇到过这个错误？？？

我在用

与这个问题“ Jersey @InjectParam 创建一个新对象而不是从 Spring 中获取”一样，使用了错误的 servlet。所以有两个容器启动，一个通过“ ContextLoaderListener ”用于Spring，一个通过“ ServletContainer ”用于Jersey 。这意味着正在启动缓存的两个实例。

使用的 Servlet 容器应该是

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

所以 Jersey 可以附加到 Spring Container
