-
轻量级: 没有复杂的技术和第三方依赖;
-
可靠存储: 使用Redis作为存储，建议使用Redis Cluster，Redis Master-Slave 或者 Redis Proxy Middleware等技术保证存储的可靠性;
-
对等的Server节点: Server节点的对等性，保证即便某些Server不可用，集群仍能工作;
-
近似实时更新: diablo使用Http长轮询来保证客户端能及时得到配置更新的通知;
-
简单的UI: diablo内嵌了一个简单易用的web界面，叫做Diablo Tower;

下载最新的压缩包；
-
或者通过源码构建:
mvn clean package -DskipTests # package located diablo-server/target/diablo-server-{version}.tar.gz -
解压缩包：
tar zxf diablo-server.tar.gz ll diabloh bin # the execute scripts conf # conf dir lib # dependency libs
-
编辑配置文件diablo.conf：
# vim ${DIABLO_HOME}/conf/diablo.conf # The server bind address BIND_ADDR=127.0.0.1 # The server listening port LISTEN_PORT=2143 # The redis host REDIS_HOST=127.0.0.1 # The redis port REDIS_PORT=6379 # The log path LOG_PATH=~/logs/diablo # The password for Diablo Tower admin TOWER_PASS=admin # The inverval(seconds) for checking server's status CHECK_SERVER_INTERVAL=5 # Enable or disable client api auth # client must config the appKey, if CLIENT_AUTH=true CLIENT_AUTH=true # Java Heap options JAVA_HEAP_OPTS="-Xms512m -Xmx512m"
-
启动或停止diablo server:
${DIABLO_HOME}/bin/diablo.sh start ${DIABLO_HOME}/bin/diablo.sh stop ${DIABLO_HOME}/bin/diablo.sh restart
-
启动diablo server后，便可通过Http访问diablo tower(如http://127.0.0.1:2143);

事先准备应用和配置项：
-
编辑应用:
-
编辑配置项:
-
-
以下针对Java客户端，其他客户端可参考该规范。
-
SimpleDiabloClient(编程模式):
-
添加maven依赖:
<dependency> <groupId>me.hao0</groupId> <artifactId>diablo-client</artifactId> <version>1.2.3</version> </dependency>
-
代码样例:
SimpleDiabloClient client = new SimpleDiabloClient(); client.setAppName("myapp"); client.setAppKey("123456"); client.setServers("127.0.0.1:2143,127.0.0.1:2144"); // 可添加配置监听 client.addListener(new ConfigListener<String>() { @Override public String name() { // 配置项名称 return "test_config1"; } @Override public void onUpdate(String newValue) { // 该方法会在本地配置更新后触发 System.out.println("test_config1 has updated to " + newValue); } }); client.start(); // 获取配置项最新的值 String testConfig = client.get("test_config"); // 获取配置项最新的json对象 MyClass myClass = client.get("test_json", MyClass.class); client.shutdown();

-
SpringDiabloClient(Spring注入模式):
-
添加maven依赖:
<dependency> <groupId>me.hao0</groupId> <artifactId>diablo-client-spring</artifactId> <version>1.2.2</version> </dependency>
-
配置片段:
<bean class="me.hao0.diablo.client.SpringDiabloClient"> <property name="appName" value="myapp" /> <property name="appKey" value="123456" /> <property name="servers" value="127.0.0.1:2143,127.0.0.1:2144" /> <!-- 可选配置 --> <property name="listeners"> <list> <ref bean="activityNoListener" /> <ref bean="timeInfoListener" /> <ref bean="timeInfosListener" /> <ref bean="timeInfoMapListener" /> </list> </property> </bean> <!-- 可配置一些监听器，会在本地配置更新后触发 --> <bean id="activityNoListener" class="me.hao0.diablo.client.listener.ActivityNoListener" /> <bean id="timeInfoListener" class="me.hao0.diablo.client.listener.TimeInfoListener" /> <bean id="timeInfosListener" class="me.hao0.diablo.client.listener.TimeInfosListener" /> <bean id="timeInfoMapListener" class="me.hao0.diablo.client.listener.TimeInfoMapListener" />
-
添加diablo配置Bean到spring上下文中, 如:
@Component public class MyAppConfig implements DiabloConfig { // 支持基本类型转换 private String activityNo; private Integer activityChannel; private Boolean activityStart; private Float activityRatio; private Long activityCount; private Double activityFee; // 支持普通json对象转换 private TimeInfo timeInfo; // 支持一级List对象转换 private List<TimeInfo> timeInfos; // 支持一级Map对象转换 private Map<String, TimeInfo> timeInfoMap; // getters and setters }
-
具体见测试用例.

-
这样一旦你通过Diablo Tower修改了对应配置项时，客户端将收到通知。
