Apache Geode cachelistener无法执行 [英] Apache geode cachelistener not executing
问题描述
这是一个新手问题,感谢您阅读.因此,我使用如下所示的复制区域启动了Geode服务器缓存过程:
This is a newbie question, thanks for reading it. So I start a Geode server cache process with a replicated region like this:
gfsh>start locator --name=myLocator
和服务器进程
start server --cache-xml-file=D:\Geode\config\cache.xml --name=myGeode --locators=localhost[10334]
cache.xml定义了一个名为myRegion
The cache.xml defined a replicated region called myRegion
<?xml version="1.0" encoding="UTF-8"?>
<cache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://geode.apache.org/schema/cache"
xsi:schemaLocation="http://geode.apache.org/schema/cache http://geode.apache.org/schema/cache/cache-1.0.xsd"
version="1.0">
<cache-server/>
<region name="myRegion" refid="REPLICATE"/>
</cache>
然后我使用.Net的Pivotal Native Client,在另一个过程中,我使用如下所示的缓存事件侦听器启动了客户端缓存:
and then I am using the Pivotal Native Client for .Net with which in another process I start up a client cache with a cache event listener as follows:
CacheFactory cacheFactory = CacheFactory.CreateCacheFactory();
Cache cache = cacheFactory.SetSubscriptionEnabled(true).Create();
RegionFactory regionFactory = cache.CreateRegionFactory(RegionShortcut.CACHING_PROXY);
IRegion<string, string> region = regionFactory.Create<string, string>("myRegion");
region.AttributesMutator.SetCacheListener(new MyEventHandler<string, string>());
MyEventHandler是:
The MyEventHandler is:
public class MyEventHandler<TKey, TVal> : ICacheListener<TKey, TVal>
{
public void AfterCreate(EntryEvent<TKey, TVal> ev)
{
Console.WriteLine("Received AfterCreate event for: {0}", ev.Key.ToString());
}
...
}
,然后在第三步中,我再次为该进程创建另一个缓存,以将一些数据放入myRegion
中.与没有侦听器的第二个过程的设置相同:
and then again in a third process I create another cache for that process to put some data into myRegion
. It's the same setup as the second process without the listener:
CacheFactory cacheFactory = CacheFactory.CreateCacheFactory();
Cache cache = cacheFactory.SetSubscriptionEnabled(true).Create();
RegionFactory regionFactory = cache.CreateRegionFactory(RegionShortcut.CACHING_PROXY);
IRegion<string, string> region = regionFactory.Create<string, string>("myRegion");
region["testKey"] = "testValue";
问题是在第三个进程将测试数据放入myRegion
之后(我可以在服务器上看到它可以正常工作),第二个进程中的侦听器看不到它.我想念什么?
The problem is after the third process puts the test data into myRegion
(that I can see on the server so that's working) the listener in the second process doesn't see it. What am I missing?
谢谢...
推荐答案
On the client where you have the listener, you need to register interest in either all or a subset of key so that the server knows to send updates to the client.
