gemfire基本使用以及spring-data-gemfire的使用

locator

启动locator gfsh>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=locator1 gfsh>status locator --host=localhost --port=10334  连接locator gfsh>connect gfsh>connect --locator=localhost[10335]  关闭locator gfsh>stop locator --name=locator1  关闭整个集群 gfsh>shutdown --include-locators=true

server

启动server gfsh>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server gfsh>stop server --name=server1

region

创建region gfsh>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region gfsh>destroy region --name=test

部署jar包(deploy)

gemfire中部署jar包分为实体类和计算类两种情况:

1.实体类: 实体类需要部署到程序的classpath路径下面；

2.计算类: 对于计算类，可以通过deploy命令手动部署;

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

maven依赖:

    <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>

配置文件:

ClientContext.xml

    <!-- 定义client-cache-->     <gfe:client-cache id="gemfireCache" pool-name="gemfirePool"/>     <!-- 定义locator连接池-->     <gfe:pool id="gemfirePool" subscription-enabled="true">         <!--<gfe:locator host="localhost" port="10334"/>-->         <gfe:locator host="10.10.10.110" port="12105"/>     </gfe:pool>      <!-- 定义客户端region -->     <gfe:client-region id="messages" cache-ref="gemfireCache" value-constraint="com.cord.demo.data.Message" shortcut="PROXY"/>

通过spring-data接口CrudRepository实现OQL查询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); ...

结论: 客户端模式更多的是对集群中数据的查询，而对集群中region的管理有限；

配置文件:

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

gemfire.properties

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

启动类注解:

ServerApplication.java

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

动态创建region:

ServerTestController.java

    ...     @Autowired     private Cache gemfireCache; //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");              ...
