使用通配符10的Ehcache配置

Question

尝试用ehcache.xml在wildfly10中实现ehcache

将ehcache.jar文件作为模块添加，并添加依赖项，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>

当我试图运行服务器war文件时，我会得到以下错误。

从d:\ehcache.xml中配置错误。最初的原因是输入流配置错误。最初的原因是__redirected.__SAXParserFactory不能转换为javax.xml.parsers.SAXParserFactory

任何线索都会有帮助。

Answer 1

您似乎使用了Ehcache 1，这个版本真的很老了。您至少应该升级到Ehcache 2，最新的版本是Ehcache 3，很可能Ehcache 1与当前的Java版本和通配符依赖项不兼容。

Answer 2

它与EhCache 3.3.1一起工作

1. 将ehcache-3.3.1.jar文件放入wildfly10_HOME\modules\system\layers\base\org\ehcache\main中
2. 在上述文件夹中编辑module.xml，如下所示
3. 代码：

字符串cacheName = "basicCacheNamit"；

try (CacheManager cacheManager = newCacheManagerBuilder()
  .withCache(cacheName,
    newCacheConfigurationBuilder(Long.class, String.class, heap(100).offheap(1, MB)))
  .build(true)) {
  Cache<Long, String> basicCache = cacheManager.getCache(cacheName, Long.class, String.class);


  basicCache.put(1L, "da one!");
  String value = basicCache.get(1L);
