Question

我正在从ehcache 2迁移到ehcache 3.5。我正在尝试使用Terracotta开源与集群共享缓存。

下面是我的Java代码，

ts(bow, frequency=c(24*60/5), start=c(2018,1,1), end=c(2018,2,28) )

有人可以帮助我转换为ehcache.xml

final CacheManagerBuilder<PersistentCacheManager> clusteredCacheManagerBuilder =
            CacheManagerBuilder.newCacheManagerBuilder()
                .with(ClusteringServiceConfigurationBuilder.cluster(URI.create("terracotta://terr.com:9410/clustered")).autoCreate()
                    .defaultServerResource("default-resource")
                    .resourcePool("pool3", 28, MemoryUnit.MB))  
                .withCache("boxMaxFileId", CacheConfigurationBuilder.newCacheConfigurationBuilder(String.class, Integer.class,
                    ResourcePoolsBuilder.newResourcePoolsBuilder()
                        .with(ClusteredResourcePoolBuilder.clusteredShared("pool3")))) ; 
        final PersistentCacheManager cacheManager = clusteredCacheManagerBuilder.build(true); 

        LOGGER.info(cacheManager.getStatus().toString());
        return cacheManager;

tc-config.xml

        <ehcache:service>
     <terracotta:cluster>
       <terracotta:connection url="terracotta://terr.com:9410/clustered"/>
      <terracotta:server-side-config auto-create="true">
        <terracotta:default-resource from="default-resource"/>
        <terracotta:shared-pool name="pool1" unit="MB">2</terracotta:shared-pool>
      </terracotta:server-side-config>
    </terracotta:cluster>
 </ehcache:service>


  <ehcache:cache alias="boxMaxFileId">
    <ehcache:key-type>java.lang.String</ehcache:key-type>
    <ehcache:value-type>java.lang.Integer</ehcache:value-type>
    <ehcache:resources>
      <ehcache:heap unit="entries">100</ehcache:heap>
      <ehcache:offheap unit="MB">1</ehcache:offheap>
      <terracotta:clustered-shared sharing="pool1" />
    </ehcache:resources>
  </ehcache:cache>

我遇到异常，例如服务器中不存在池名称“ pool1”。

这是转换后的xml。为了共享，我们需要使用以上格式。
