JFinal配置EhCachePlugin后启动时报错：

Question

配置方式：

public void configPlugin(Plugins me) {
        ...     
        //EhCache缓存
		me.add(new EhCachePlugin());

	}

引入了ehcache-core-2.6.10.jar以及slf4j相关日志包，更换过2.7.x&2.9.x的ehcache包都不行。

错误异常的堆栈输出信息如下：

Answer 1

提示 NoSuchMethodException，应该是 ehcache 版本不对，仔细看一下项目引用的所有 jar 包的引用关系，如果有多次引用，老版本可能被生效

Answer 2

引用来自“JFinal”的评论

jfinal 官方网站有一个  jfinal-1.9-all.zip 供下载，里面提供了 ehcache 的所需要的 jar 包，试一下这个应该可以，都是经过严格测试的
