Question

我的项目正在使用Spring Boot 2.0.4-RELEASE版本。我们正在部署到Pivotal Cloud Foundry上，并且正在使用使用Apache Geode的Pivotal Cloud Cache服务服务。如果我使用gemfire shell创建Cloud Cache区域，则我的代码已启动并正在运行，但是我想从我的代码中创建这些区域，以便不遗漏任何内容。我有以下配置类，在其中尝试创建区域

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

任何人都可以提供任何建议以帮助我在我的代码中创建Pivotal Cloud Cache（Apache Geode）区域，而不是必须使用gemfire shell创建它们

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特权的操作员通过gfsh，单个cache.xml配置文件或{{3} }。允许客户随意创建区域可能会适得其反，并在您的集群上生成大量未使用的区域以及不必要的噪音和开销，这在生产环境中根本不建议这样做。

也就是说，cluster configuration service允许您自动从客户端应用程序Spring Data for Apache Geode/GemFire，这在开发环境中很有用。我不知道Pivotal Cloud Cache内部策略和限制是否允许这样做，您可能想直接与Pivotal进行检查。

希望这会有所帮助。干杯。
