Spring Boot连接到数据透视云缓存

Question

我的项目使用的是Spring Boot 2.0.4-RELEASE版本。我们正在Pivotal Cloud Foundry上进行部署，并使用使用Apache Geode的Pivotal云缓存服务。如果我使用gemfire shell创建云缓存区域，我的代码已经启动并运行，但我想从我的代码中创建这些区域，这样就不会遗漏任何内容。我有下面的配置类，我试图在其中创建一个区域

package com.mycompany.services.config;
import org.apache.geode.cache.ExpirationAction;
import org.apache.geode.cache.ExpirationAttributes;
import org.apache.geode.cache.GemFireCache;
import org.apache.geode.cache.RegionShortcut;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.gemfire.PartitionedRegionFactoryBean;
import org.springframework.data.gemfire.config.annotation.EnableCachingDefinedRegions;
import org.springframework.data.gemfire.config.annotation.EnablePdx;
@Configuration
@EnableCachingDefinedRegions
@EnablePdx()
public class Config {
@Bean
public PartitionedRegionFactoryBean<?, ?> createCacheRegion(GemFireCache gemfireCache) {
int expirationTime = 600;
String regionName = "cacheRegion";
PartitionedRegionFactoryBean<?, ?> newRegion = new PartitionedRegionFactoryBean<>();
newRegion.setCache(gemfireCache);
newRegion.setClose(false);
newRegion.setPersistent(true);
newRegion.setName(regionName);
ExpirationAttributes entryTimeToLive = new ExpirationAttributes(expirationTime,  ExpirationAction.INVALIDATE);
newRegion.setEntryTimeToLive(entryTimeToLive);
newRegion.setShortcut(RegionShortcut.REPLICATE);
return newRegion;
}
}

然而，当这段代码在Pivotal Cloud Foundry上运行时，我得到了以下错误

有人能就我需要做什么来在我的代码中创建数据透视云缓存(Apache Geode(区域提供任何建议吗？而不是必须使用gemfire shell 来创建它们

谢谢Damien

Answer 1

客户端应用程序无法在服务器上创建区域，这项任务应由具有管理员权限的操作员通过gfsh、单个cache.xml配置文件或cluster configuration service执行。允许客户端任意创建区域可能会适得其反，并在集群中产生大量未使用的区域以及不必要的噪音和开销，这对于生产环境来说是完全不建议的。

也就是说，Spring Data for Apache Geode/GemFire允许您自动将配置从客户端应用程序推送到集群，这在开发环境中很有用。我不知道Pivotal云缓存内部策略和限制是否允许这样做，您可能想直接与Pivotal核实。

希望这能有所帮助。干杯
