如何在AWS Elasti Cache Auto Discovery功能中使用simple-spring-memcached库(SSM)?我们使用spymemcached作为客户端。
答案 0 :(得分:0)
所以目前你正在使用spymemcached并希望使用简单的spring memcached(SSM)添加缓存层,对吧?如果是,那么请提供spymemcached的当前配置。使用SSM应该很容易使用相同的配置。

我在SSM中添加了使用AWS ElastiCache Cluster Client的新专用memcached提供程序。它在master branch上可用,尚未发布。如果您从主服务器构建SSM或使用此repository中提供的快照,则可以使用自动发现功能。
删除 spymemcached-provider 和 spymemcached 的依赖项,而不是添加新的依赖项:
<dependency>
<groupId>com.google.code.simple-spring-memcached</groupId>
<artifactId>aws-elasticache-provider</artifactId>
<version>3.4.1-SNAPSHOT</version>
</dependency>
使用以下配置:

让我知道它是否适合你。
更新2
具有AWS Auto Discovery功能的新简单Spring Memcached版本3.5.0可在github和中央maven存储库中使用。
