GemFire basic use and use of Spring-data-gemfire

1. Use of the installation program

• Locator

启动locatorgfsh>start locator --name=locator1  指定端口启动gfsh>start locator --name=locator1  --port=12105指定端口和绑定ip启动gfsh>start locator --name=locator1 --port=12105 --bind-address=10.10.10.110查看locator状态gfsh>status locator --name=locator1gfsh>status locator --host=localhost --port=10334连接locatorgfsh>connectgfsh>connect --locator=localhost[10335]关闭locatorgfsh>stop locator --name=locator1关闭整个集群gfsh>shutdown --include-locators=true

• Server

启动servergfsh>start server --name=server1指定locator启动gfsh>start server --name=server1 --locators=localhost[10334]指定端口和locator启动gfsh>start server --name=server1 --server-port=12104  --locators=10.10.10.110[12105]停止servergfsh>stop server --name=server1

• Region

创建regiongfsh>create region --name=test --type=REPLICATE_PERSISTENT存储kv值gfsh>put --region=test --key="a" --value="A"查询信息gfsh>query --query="select * from /test"查看region信息gfsh>describe region --name=test销毁regiongfsh>destroy region --name=test

• Deploy the jar package (deploy)

The deployment jar packages in GemFire are divided into entity classes and calculation classes in two cases:

1. Entity classes: Entity classes need to be deployed under the CLASSPATH path of the program;

2. Calculation class: For the calculation class, it can be deployed manually through the Deploy command;

部署jar包gfsh>deploy --jars=/data/local/gemfire/apache-geode-1.5.0/lib/geode-demo-1.0-SNAPSHOT.jar查看已部署jar包gfsh>list deployed卸载jar包gfsh>undeploy --jar=geode-demo-1.0-SNAPSHOT.jar

2. Combined with the use of Spring-data

Maven dependencies:

    <dependency>      <groupId>org.springframework.data</groupId>      <artifactId>spring-data-gemfire</artifactId>      <version>2.0.6.RELEASE</version>      <exclusions>        <exclusion>          <groupId>io.pivotal.gemfire</groupId>          <artifactId>geode-lucene</artifactId>        </exclusion>      </exclusions>    </dependency>

2.1 Client Mode

• Configuration file:

clientcontext. xml

    <!--definition client-cache-->    <gfe:client-cacheid="Gemfirecache"pool-name="Gemfirepool"/>    <!--define Locator connection pool --    <gfe:poolid="Gemfirepool"subscription-enabled="true">        <!--<gfe:locator host= "localhost" port= "10334"/>-->        <gfe:locatorhost="10.10.10.110"port="12105"/>    </gfe:pool>    <!--Define client region--    <gfe:client-regionid="Messages"cache-ref="Gemfirecache"value-constraint="Com.cord.demo.data.Message"shortcut="PROXY"/>

• The OQL query region is implemented through the Spring-data interface crudrepository:

Messagereposirory.java

@Repository@DependsOn("gemfireCache")publicinterfaceextends CrudRepository<Message, String>{    @Query("SELECT * FROM /messages m WHERE m.message = $1")    findByMessage(String message);    @Query("SELECT * FROM /messages m WHERE m.message IN SET $1")    findByMessages(List<String> messages);}

Clienttestcontroller.java

...        List<Message> c1 = reposirory.findByMessage("C");        c1.stream().forEach(System.out::println);...

conclusion : The client mode is more the query of the data in the cluster, but the management of region in the cluster is limited.

2.2 Service-side embedding mode (server)

Configuration file:

Servercontext.xml

<!-- 定义region--><gfe:replicated-region id="messages" value-constraint="com.cord.demo.data.Message"/>

Application.properties

#server端口和绑定地址spring.data.gemfire.cache.server.port=41414spring.data.gemfire.cache.server.bind-address=localhost#locator端口和地址spring.data.gemfire.locator.host=localhostspring.data.gemfire.locator.port=10335

Gemfire.properties

#开启jmxjmx-manager=truejmx-manager-start=true#指定访问locator集群locators=localhost[10334],localhost[10335]

Start class Annotations:

Serverapplication.java

@SpringBootApplication@CacheServerApplication"embedServer")@EnableLocator@EnableGemfireRepositories"com.cord.demo.dao")@ImportResource(locations = {"classpath:ServerContext.xml"})publicclassimplements CommandLineRunner {  ...}

Dynamically Create region:

Servertestcontroller.java

    ...    @Autowired    private//系统默认的cache名      ...         /**获取region工厂*/        RegionFactory<String, String> rf = gemfireCache.createRegionFactory(RegionShortcut.REPLICATE);        /**创建region*/        Region<String, String> region = rf.create("test");             ...
