开源配置中心 - Apollo
Apollo（阿波罗）是携程框架部门研发的配置管理平台，能够集中化管理应用不同环境、不同集群的配置，配置修改后能够实时推送到应用端，并且具备规范的权限、流程治理等特性。服务端基于Spring Boot和Spring Cloud开发，打包后可以直接运行，不需要额外安装Tomcat等应用容器。
检出代码
可以fork下然后本地使用idea打开
数据库脚本
执行以下脚本创建ApolloConifgDB、ApolloPortalDB
启动configservice adminservice
Main class配置
com.ctrip.framework.apollo.assembly.ApolloApplication
VM opions
-Dapollo_profile=github -Dspring.datasource.url=jdbc:mysql://localhost:3306/ApolloConfigDB?characterEncoding=utf8 -Dspring.datasource.username=root -Dspring.datasource.password= Program arguments --configservice --adminservice
启动完后，打开 http://localhost:8080可以看到apollo-configservice和apollo-adminservice都已经启动完成并注册到Eureka
启动Apollo-Portal
Main class配置
com.ctrip.framework.apollo.portal.PortalApplication -Dapollo_profile=github,auth -Ddev_meta=http://localhost:8080/ -Dserver.port=8070 -Dspring.datasource.url=jdbc:mysql://localhost:3306/ApolloPortalDB?characterEncoding=utf8 -Dspring.datasource.username=root -Dspring.datasource.password=
如果启用了auth profile的话，默认的用户名是apollo，密码是admin
应用在SIT、UAT、生产环境机器上
1.新增目录/opt/data/目录，且有可读写权限；
2.新增文件：/opt/settings/server.properties 且加入配置:
env=DEV sit: env=FAT uat: env=UAT 生产：env=PRO
客户端例子
@Component 设置组件名称
@RefreshScope 指定配置改变可以刷新
@ConfigurationProperties(prefix = "redis.cache")
@Component("sampleRedisConfig")
@RefreshScope
public class SampleRedisConfig {
private static final Logger logger = LoggerFactory.getLogger(SampleRedisConfig.class);
private int expireSeconds;
private String clusterNodes;
private int commandTimeout;
private Map<String, String> someMap = Maps.newLinkedHashMap();
private List<String> someList = Lists.newLinkedList();
@PostConstruct
private void initialize() {
logger.info(
"SampleRedisConfig initialized - expireSeconds: {}, clusterNodes: {}, commandTimeout: {}, someMap: {}, someList: {}",
expireSeconds, clusterNodes, commandTimeout, someMap, someList);
}
public void setExpireSeconds(int expireSeconds) {
this.expireSeconds = expireSeconds;
}
public void setClusterNodes(String clusterNodes) {
this.clusterNodes = clusterNodes;
}
public void setCommandTimeout(int commandTimeout) {
this.commandTimeout = commandTimeout;
}
public Map<String, String> getSomeMap() {
return someMap;
}
public List<String> getSomeList() {
return someList;
}
@Override
public String toString() {
return String.format(
"[SampleRedisConfig] expireSeconds: %d, clusterNodes: %s, commandTimeout: %d, someMap: %s, someList: %s",
expireSeconds, clusterNodes, commandTimeout, someMap, someList);
}
}
设置监听
@Component
public class SpringBootApolloRefreshConfig {
private static final Logger logger = LoggerFactory.getLogger(SpringBootApolloRefreshConfig.class);
@Autowired
private ApolloRefreshConfig apolloRefreshConfig;
@Autowired
private SampleRedisConfig sampleRedisConfig;
@Autowired
private RefreshScope refreshScope;
@ApolloConfigChangeListener
public void onChange(ConfigChangeEvent changeEvent) {
logger.info("before refresh {}", sampleRedisConfig.toString());
refreshScope.refresh("sampleRedisConfig");
logger.info("after refresh {}", sampleRedisConfig.toString());
}
}
