例外：java。lang.NoClassDefFoundError:org。ehcache。CacheMangerBuilder

Question

我会先说“我不知道我在用java做什么”，更不用说ehcache了，但我正在努力学习

也就是说，在添加ehcache之前，我编写的代码运行良好。我只是简单地写文件和读文件，工作很好，但速度很慢，所以我试图通过使用缓存来加快速度

当我运行我的程序时，我得到以下错误，我不明白它告诉我什么是错误的：

Exception in thread "Connect thread - [6, 5]." java.lang.NoClassDefFoundError: org.ehcache.CacheManagerBuilder at com.ibm.tpf.internal.ZSTATEngine.doFilter(ZSTATEngine.java:24) at com.ibm.tpf.etos.filter.FilterFramework.filterMessage(FilterFramework.java:229) at com.ibm.tpf.etos.api.APIFramework.addMessage(APIFramework.java:304) at com.ibm.tpf.etos.comm.ETOSConnection.addMessage(ETOSConnection.java:765) at com.ibm.tpf.etos.comm.ETOSModel._connect(ETOSModel.java:528) at com.ibm.tpf.etos.comm.ETOSModel$ConnectThread.run(ETOSModel.java:706)

我试图模仿ehcache 3.0文档页面上的缓存代码。。。但我一定是做错了什么。有人介意看一下吗
