java客户端线上Apollo服务端的实现

发布日期： 2026-01-12 阅读量： 作者： 用户投稿

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;

/**

 */
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
