1.安裝程式的使用

• locator

啟動locatorgfsh>start locator --name=locator1  指定連接埠啟動gfsh>start locator --name=locator1  --port=12105指定連接埠和綁定ip啟動gfsh>start locator --name=locator1 --port=12105 --bind-address=10.10.10.110查看locator狀態gfsh>status locator --name=locator1gfsh>status locator --host=localhost --port=10334串連locatorgfsh>connectgfsh>connect --locator=localhost[10335]關閉locatorgfsh>stop locator --name=locator1關閉整個叢集gfsh>shutdown --include-locators=true

• server

啟動servergfsh>start server --name=server1指定locator啟動gfsh>start server --name=server1 --locators=localhost[10334]指定連接埠和locator啟動gfsh>start server --name=server1 --server-port=12104  --locators=10.10.10.110[12105]停止servergfsh>stop server --name=server1

• region

建立regiongfsh>create region --name=test --type=REPLICATE_PERSISTENT儲存kv值gfsh>put --region=test --key="a" --value="A"查詢資訊gfsh>query --query="select * from /test"查看region資訊gfsh>describe region --name=test銷毀regiongfsh>destroy region --name=test

• 部署jar包(deploy)

gemfire中部署jar包分為實體類和計算類兩種情況:

1.實體類: 實體類需要部署到程式的classpath路徑下面；

2.計算類: 對於計算類，可以通過deploy命令手動部署;

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卸載jar包gfsh>undeploy --jar=geode-demo-1.0-SNAPSHOT.jar

2. 結合spring-data的使用

maven依賴:

    <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 用戶端模式(client)

• 設定檔:

ClientContext.xml

    <!-- 定義client-cache-->    <gfe:client-cache id="gemfireCache" pool-name="gemfirePool"/>    <!-- 定義locator串連池-->    <gfe:pool id="gemfirePool" subscription-enabled="true">        <!--<gfe:locator host="localhost" port="10334"/>-->        <gfe:locator host="10.10.10.110" port="12105"/>    </gfe:pool>    <!-- 定義用戶端region -->    <gfe:client-region id="messages" cache-ref="gemfireCache" value-constraint="com.cord.demo.data.Message" shortcut="PROXY"/>

• 通過spring-data介面CrudRepository實現OQL查詢region:

MessageReposirory.java

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

ClientTestController.java

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

結論: 用戶端模式更多的是對叢集中資料的查詢，而對叢集中region的管理有限；

2.2 服務端嵌入模式(server)

設定檔:

ServerContext.xml

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

application.properties

#server連接埠和綁定地址spring.data.gemfire.cache.server.port=41414spring.data.gemfire.cache.server.bind-address=localhost#locator連接埠和地址spring.data.gemfire.locator.host=localhostspring.data.gemfire.locator.port=10335

gemfire.properties

#開啟jmxjmx-manager=truejmx-manager-start=true#指定訪問locator叢集locators=localhost[10334],localhost[10335]

啟動類註解:

ServerApplication.java

@SpringBootApplication@CacheServerApplication(name = "embedServer")@EnableLocator@EnableGemfireRepositories(basePackages = "com.cord.demo.dao")@ImportResource(locations = {"classpath:ServerContext.xml"})public class ServerApplication implements CommandLineRunner {  ...}

動態建立region:

ServerTestController.java

    ...    @Autowired    private Cache gemfireCache; //系統預設的cache名      ...         /**擷取region工廠*/        RegionFactory<String, String> rf = gemfireCache.createRegionFactory(RegionShortcut.REPLICATE);        /**建立region*/        Region<String, String> region = rf.create("test");             ...
