问题
I watched video from Springone Platform and John Blum as speaker and interested try myself in Geode/Gemfire setup but with setup as described in Spring Data for Apache Geode Reference Guide
So i make spring boot geode client, locator and cache server using Eclipse, and i have problems when :
- Start spring locator, start cache server, and start client with restcontroller so I can post my POJO TitleContent and get my list of TitleContent. Client give me exception Caused by:
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)

I remark @EnableClusterConfiguration(useHttp=true) and start Client again and now able to run. Now I give it a try with a POJO post to my restcontroller and get this exception :

This time I un-remark //@EnableClusterConfiguration(useHttp=true) but I remove useHttp and just use @EnableClusterConfiguration, (I suspected error because of this). I stop Spring Client and start it again. Now it fails, and says : org.apache.geode.cache.RegionExistsException: /TitleContent.

The Region looks like not persist to disk.
Questions :
At point 3 as exception was thrown, but definitely TitleContent region was created. But why exception is thrown?
Can somebody pinpoint what I missed, why @EnableClusterConfiguration behave strangely in my case and why Region is not persisted to disk (according to ref. manual, it should be persisted to disk by DEFAULT DiskStore at 7.12.7 ref. manual). I am sorry for such very long questions. I just couldn't make it shorter.
Thank you if somebody may be able to help, I really appreciate it.

回答1:
I finally found the way around this, after reading answer from John Blum several time from SpringData Gemfire DiskStore.
Definitely I couldn't use @EnableClusterConfiguration in my case (still wondering why). According to John, we are able to create Region using gfsh. From this I get an idea to do the same at Spring Boot CacheServer. So, how if I define my POJO at CacheServer and let annotation @EnableEntityDefinedRegions do the job to create the region at CacheServer side. Again I borrow
serverRegionShortcut = RegionShortcut.PARTITION_PERSISTENT
from John but I put it at
@EnableEntityDefinedRegions
Beside that I also need to persist my PDX type (Spring and/or Geode Gemfire do not like me if I am not persisting Pdx type at CacheServer side). So, I am using the same method to persist from SpringData Gemfire DiskStore but I implement it at CacheServer side with some additional entry at application.properties to tell spring to persist Pdx type as well.
In that way, I am able to successfully create and persisting Region at CacheServer side and also persisting Pdx as well.
Here is the complete code and application.properties I made with borrowing the idea from SpringData Gemfire DiskStore.
I appreciate if anybody able to tell me whether this work around is a good way to do or is there any other way or any better idea (still wondering though why @EnableClusterConfiguration doesn't like me while anybody else has no problem with it :=(, so if there is anybody who is able to tell me where is(are) my mistake(s) I really appreciate it ).
CLIENT :
@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);
}
}
At client side the same POJO, Repository and RestController and nothing in application.properties except for server.port definition.
CACHESERVER :
@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
Upon CacheServer start, region is created and is able to persist / save to disk.
