我正在尝试将 play2-elasticsearch 插件用于 playframework2 版本 2.1.3 我刚刚完成了 github 示例所说的，唯一的修改是更改此行以使用本地 IP 地址上的服务器。

elasticsearch.client="127.0.0.1:9300"

但是当我尝试运行该示例时，我得到以下异常，有什么想法吗？我在带有 jdk1.7 的 mac 上使用 play framework 2.1.3

从堆栈跟踪看来，您使用的0.5.4版本似乎与 play 2.1.3 不兼容（仅与 play 2.1.0 兼容）。

如果您查看 README 文件中的“版本”表，您会看到0.7-SNAPSHOT如果您使用 play 2.1.3，则需要该版本。尝试使用这个。
