Spring 引导连接到 Pivotal Cloud Cache

Question

我的项目正在使用 Spring 引导版本 2.0.4-RELEASE。我们正在部署到 Pivotal Cloud Foundry 并使用使用 Apache Geode 的 Pivotal Cloud Cache 服务。如果我使用 gemfire shell 创建云缓存区域，我的代码已经启动运行但我想从我的代码创建这些区域，这样就不会遗漏任何内容。我有以下配置 class，我尝试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;
    }

}

但是 - 当此代码在 Pivotal Cloud Foundry 上运行时 - 我收到以下错误

任何人都可以建议我需要做什么才能在我的代码中创建 Pivotal Cloud Cache (Apache Geode) 区域，而不是必须使用 gemfire shell

谢谢达米安

Answer 1

客户端应用程序无法在服务器上创建区域，该任务应由具有管理员权限的操作员通过 gfsh, individual cache.xml configuration files or the cluster configuration service 执行。允许客户端任意创建区域可能会适得其反，并在您的集群上产生大量未使用的区域以及不必要的噪音和开销，完全不建议在生产环境中使用。

也就是说，Spring Data for Apache Geode/GemFire allows you to push your configuration to the Cluster 自动从客户端应用程序，这在开发环境中很有用。我不知道 Pivotal Cloud Cache 内部政策和限制是否允许这样做，您可能想直接与 Pivotal 联系。

希望这对您有所帮助。干杯。
