java客户端线上Apollo服务端的实现
作者:赵山河丿
这篇文章主要介绍了java客户端线上Apollo服务端的实现,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
1.指定环境
1.1 在C:\opt\settings\下有server.properties
env=DEV是对应服务器上的如下图
apollo.meta=http://192.168.1.143:8070是你服务端的端口号
1.2 在C:\opt\data\babel023\config-cache有这四个文件
2.在META-INF下创建app.properties
app.properties下的内容app.id对应Apollo服务端的id
3.创建个SimpleApolloConfig
package com.fqgj.rest; import com.google.common.base.Charsets; import com.ctrip.framework.apollo.Config; import com.ctrip.framework.apollo.ConfigChangeListener; import com.ctrip.framework.apollo.ConfigService; import com.ctrip.framework.apollo.model.ConfigChange; import com.ctrip.framework.apollo.model.ConfigChangeEvent; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; /** * @author Jason Song(song_s@ctrip.com) */ public class SimpleApolloConfigDemo { private static final Logger logger = LoggerFactory.getLogger(SimpleApolloConfigDemo.class); private String DEFAULT_VALUE = "undefined"; private Config config; public SimpleApolloConfigDemo() { ConfigChangeListener changeListener = new ConfigChangeListener() { @Override public void onChange(ConfigChangeEvent changeEvent) { logger.info("Changes for namespace {}", changeEvent.getNamespace()); for (String key : changeEvent.changedKeys()) { ConfigChange change = changeEvent.getChange(key); logger.info("Change - key: {}, oldValue: {}, newValue: {}, changeType: {}", change.getPropertyName(), change.getOldValue(), change.getNewValue(), change.getChangeType()); } } }; config = ConfigService.getAppConfig(); config.addChangeListener(changeListener); } private String getConfig(String key) { String result = config.getProperty(key, DEFAULT_VALUE); logger.info(String.format("Loading key : %s with value: %s", key, result)); return result; } public static void main(String[] args) throws IOException { SimpleApolloConfigDemo apolloConfigDemo = new SimpleApolloConfigDemo(); System.out.println( "Apollo Config Demo. Please input key to get the value. Input quit to exit."); while (true) { System.out.print("> "); String input = new BufferedReader(new InputStreamReader(System.in, Charsets.UTF_8)).readLine(); if (input == null || input.length() == 0) { continue; } input = input.trim(); if (input.equalsIgnoreCase("quit")) { System.exit(0); } String ccc= apolloConfigDemo.getConfig(input); System.out.println(ccc); } } }
运行结果如下
