问题创建区域并将区域持久化到磁盘 Geode Gemfire Spring Boot答案

【问题标题】：Problem creating region and persist region to disk Geode Gemfire Spring Boot问题创建区域并将区域持久化到磁盘 Geode Gemfire Spring Boot
【发布时间】：2019-10-29 03:43:19
【问题描述】：

我观看了来自 Springone Platform 和 John Blum 作为演讲者的视频，并有兴趣尝试使用 Geode/Gemfire 设置，但设置如 Spring Data for Apache Geode Reference Guide 中所述

所以我使用 Eclipse 制作 spring boot geode 客户端、定位器和缓存服务器，但遇到问题时：

启动 spring 定位器，启动缓存服务器，并使用 restcontroller 启动客户端，这样我就可以发布我的 POJO TitleContent 并获取我的 TitleContent 列表。客户给我异常原因：org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://localhost:7070/gemfire/v1/regions": Connection refused (Connection refused); nested exception is java.net.ConnectException: Connection refused (Connection refused)

我注意到@EnableClusterConfiguration(useHttp=true) 并再次启动客户端，现在可以运行了。现在我尝试将 POJO 帖子发送到我的 restcontroller 并得到这个异常：

这次我取消注释 //@EnableClusterConfiguration(useHttp=true) 但我删除了 useHttp 并只使用 @EnableClusterConfiguration，（因此我怀疑错误）。我停止 Spring Client 并重新启动它。现在它失败了，并说：org.apache.geode.cache.RegionExistsException：/TitleContent。

这次我再次备注 //@EnableClusterConfiguration 并再次启动 Spring Client。这次它运行了，我用相同的 POJO 再试一次。它成功了！

我尝试在控制器上使用 GET rest 端点成功获取 TitleContent 列表。
现在我将它们全部关闭并重新启动。我尝试获取第 5 点中的列表，并在完整日志中给我例外：

区域看起来没有持久化到磁盘。

问题：

在第 3 点引发异常，但肯定创建了 TitleContent 区域。但是为什么会抛出异常呢？

有人可以指出我错过了什么，为什么 @EnableClusterConfiguration 在我的情况下表现异常以及为什么 Region 没有持久化到磁盘（根据参考手册，它应该由 DEFAULT DiskStore 在 7.12.7 参考手册中持久化到磁盘） .对于这么长的问题，我很抱歉。我就是不能让它更短。

如果有人可以提供帮助，我真的很感激。

标签： java spring spring-boot gemfire geode

【解决方案1】：

在从SpringData Gemfire DiskStore 多次阅读 John Blum 的回答后，我终于找到了解决方法。

在我的情况下，我绝对不能使用@EnableClusterConfiguration（仍然想知道为什么）。根据 John 的说法，我们可以使用 gfsh 创建 Region。由此我想到在 Spring Boot CacheServer 上做同样的事情。那么，如果我在 CacheServer 定义我的 POJO 并让注释 @EnableEntityDefinedRegions 完成在 CacheServer 端创建区域的工作。我又借了

serverRegionShortcut = RegionShortcut.PARTITION_PERSISTENT

来自约翰，但我把它放在了

@EnableEntityDefinedRegions

除此之外，我还需要保留我的 PDX 类型（如果我不在 CacheServer 端保留 Pdx 类型，Spring 和/或 Geode Gemfire 不喜欢我）。因此，我使用相同的方法从SpringData Gemfire DiskStore 持久化，但我在 CacheServer 端实现它，并在 application.properties 中添加一些额外条目，以告诉 spring 也持久化 Pdx 类型。

通过这种方式，我能够在 CacheServer 端成功创建和持久化 Region，并且还可以持久化 Pdx。

这是我借用 SpringData Gemfire DiskStore 的想法制作的完整代码和 application.properties。

如果有人能告诉我这种解决方法是否是一种好方法，或者是否有任何其他方法或更好的想法，我很感激（仍然想知道为什么@EnableClusterConfiguration 不喜欢我，而其他人对此没有任何问题它：=（，所以如果有人能够告诉我我的错误在哪里，我真的很感激）。

客户：

@SpringBootApplication
@ClientCacheApplication(logLevel = "debug", locators = {@Locator(host = "localhost", port = 10334)})
@EnablePool(name="neptunusPool", servers=@Server(host="localhost", port=41414))
@EnableGemfireRepositories(basePackageClasses= {TitleContentRepository.class})
@EnableEntityDefinedRegions(basePackageClasses= {TitleContent.class
})
//@ReplicateRegion
//@EnableClusterDefinedRegions
//@EnableCachingDefinedRegions
//@EnableGemfireCaching
@EnableIndexing
//@EnableClusterConfiguration
@EnablePdx

public class CommerceHostGeodeApplication {

    public static void main(String[] args) {

        SpringApplication.run(CommerceHostGeodeApplication.class, args);

    }

}

在客户端，相同的 POJO、Repository 和 RestController，application.properties 中除了 server.port 定义之外没有任何内容。

缓存服务器：

@SpringBootApplication
@CacheServerApplication(locators="localhost[10334]", name="GeodeServerApplication" )
@EnableCacheServer(name="neptunus", autoStartup=true, hostnameForClients = "localhost", port = 41414)
@EnableCachingDefinedRegions
@EnableGemfireCaching
@EnablePdx
@EnableManager
@EnableHttpService
@EnableDiskStore(name = "disk_store")
@EnableEntityDefinedRegions(basePackageClasses= {TitleContent.class
}, serverRegionShortcut = RegionShortcut.PARTITION_PERSISTENT)
public class GeodeServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(GeodeServerApplication.class, args);
    }

}

CACHESERVER application.properties：

server.port=15010
spring.data.gemfire.disk.store.name=disk_store
spring.data.gemfire.disk.store.directory.location=/Users/ars/geode/data
spring.data.gemfire.pdx.disk-store-name=disk_store
spring.data.gemfire.pdx.persistent=true
spring.data.gemfire.management.use-http=true

在 CacheServer 启动时，区域被创建并且能够持久化/保存到磁盘。
