spring cloud 阿波罗 apollo 本地开发环境搭建过程

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

apollo github

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

• apollo.scripts.sql.apolloconfigdb.sql
• apollo.scripts.sql.apolloportaldb.sql

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());
 }
}
