Question

我正在尝试配置ehcache多播以将其集中到两台服务器上。这就是我得到的..错误也有我用来连接的属性。我不确定我是否遗漏了任何财产。

没有试图回避这个问题的真正答案......（我在这里也不会想到答案）所以把它作为一个FYI。坦率地说，我试图完全摆脱点对点复制......因为它具有竞争条件和并发异常的可能性+通常更复杂且难以实现......

如果你有权这样做，我会转向ehcache的分布式缓存版本，名为BigmemoryMax - http://terracotta.org/products/bigmemorymax（不要被命名混淆......它仍然是EhCache ...... ehcache自然“连接”的分布式进程， free ，最多可支持4个客户端+ 4GB内存。

设置非常简单，允许您无缝同步多个客户端缓存，并支持各种企业功能（即交易，高可用性等等）
