jboss - 使用 Wildfly 10 配置 Ehcache

Question

尝试在wildfly10中使用ehcache.xml实现ehcache

添加了 ehcache.jar 文件作为模块并添加了依赖项，如下所述:

   <resources>
       <resource-root path="ehcache-1.2.2.jar"/> 
   </resources>

   <dependencies>
       <module name="org.apache.commons.logging"/>
       <module name="org.apache.log4j"/>
       <module name="javax.xml.parsers"/> 
   </dependencies>


</module>

当我尝试运行服务器 war 文件时出现以下错误。

Error configuring from d:\ehcache.xml. Initial cause was Error configuring from input stream. Initial cause was __redirected.__SAXParserFactory cannot be cast to javax.xml.parsers.SAXParserFactory

任何线索都会有所帮助。

堆栈跟踪:

• net.sf.ehcache.CacheException: 配置错误
  d:\ehcache\ehcache.xml。最初的原因是配置错误
  输入流。最初的原因是 __redirected.__SAXParserFactory
  无法转换为 javax.xml.parsers.SAXParserFactory

你好像用的是Ehcache 1，这个版本真的真的真的很老了。您至少应该升级到 Ehcache 2。最新的是 Ehcache 3。Ehcache 1 很可能与您当前的 Java 版本和 wildfly 依赖项不兼容。
