Spring Data Gemfire - Apache Geode Cache Listener Client Sample

This sample application demonstrates using Spring Data Gemfire for Apache Geode in a standalone Java application with a cache client and a single client region with a simple CacheListener.

You can run the application with the following steps.

1. Download Geode binary and unzip/untar at the preferable directory.
2. Open your console, set environment variable like the following according to your environment.

• export JAVA_HOME=/path/to/JDK8_root
• export PATH=$JAVA_HOME/bin:/pat/to/Geode_root/bin:$PATH

3. Go to /[project root] and start a locator and two servers like the following

• sh ./startLocator.sh
• sh ./startCS1.sh
• sh ./startCS2.sh

4. Start a client application (CacheListenerVisualizer) from IDE
5. From your console, start gfsh with interactive mode like the following.

• gfsh

6. Execute some command and put something data like the following. You can see the client application respond according to your put command execute.

   gfsh>connect --locator=localhost[55221]

   Connecting to Locator at [host=localhost, port=55221] ..

   Connecting to Manager at [host=localhost, port=1099] ..

   Successfully connected to: [host=localhost, port=1099]

   gfsh>list members

   Name | Id

   ------- | --------------------------------------------

   locator | localhost(locator:2324:locator):1024

   server1 | localhost(server1:2368):1025

   server2 | localhost(server2:2387):1026

   gfsh>put --key=key1 --value=value1 --region=myRegion

   Result : true

   Key Class : java.lang.String

   Key : key1

   Value Class : java.lang.String

   Old Value :

   gfsh>put --key=key2 --value=value2 --region=myRegion

   Result : true

   Key Class : java.lang.String

   Key : key2

   Value Class : java.lang.String

   Old Value :

   gfsh>put --key=key2 --value=value2_2 --region=myRegion

   Result : true

   Key Class : java.lang.String

   Key : key2

   Value Class : java.lang.String

   Old Value : value2

   gfsh>put --key=key3 --value=value3 --region=myRegion

   Result : true

   Key Class : java.lang.String

   Key : key3

   Value Class : java.lang.String

   Old Value :

   gfsh>quit

7. Stop the servers and the locator like the following from your console.

• sh ./stopCS2.sh
• sh ./stopCS1.sh
• sh ./stopLocator.sh

---

If you see the following message when starting your locator, ...

Please use "connect --locator=192.168.1.100[55221]" to connect Gfsh to the 	locator.

then you may have to add the following line at /etc/hosts according to your environment to start a locator and servers with using gfsh

[your machine IP address] localhost

ex) 192.168.1.100	localhost
