问题描述
我正在遵循基本示例here
我从Maven Central下载了ehcache-clustered-kit版3.8.0，并将其解压缩到我的计算机上。除了修改sh脚本以正确设置JAVA_HOME之外，我没有进行任何修改。
我使用默认的OOB配置（即：省略-f参数）执行了该操作：
./start-tc-server.sh
来自[ehcache root]/server/bin文件夹。
我正在像这样初始化CacheManager：
private CacheManager setup() {
CacheManagerBuilder<PersistentCacheManager> clusteredCacheManagerBuilder =
CacheManagerBuilder.newCacheManagerBuilder()
.with(ClusteringServiceConfigurationBuilder.cluster(URI.create("terracotta://localhost:9410/my-application"))
.autocreate(s -> s));
PersistentCacheManager cacheManager = clusteredCacheManagerBuilder.build(true);
return cacheManager;
}
我收到此异常：

我在做什么错了？
解决方法
我的错误。
对于一个错字，我在Java项目中包含了错误的依赖项：
<dependency>
<groupId>org.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>3.9.0</version>
</dependency>
<dependency>
<groupId>org.ehcache</groupId>
<artifactId>ehcache-clustered</artifactId>
<version>3.9.0</version>
</dependency>
代替版本3.8.0。
这与我安装的Ehcache群集（3.8.0）产生了冲突。一旦更正了依赖版本，我就可以成功连接。
