Apollo的部署這裏不作複述，網上很詳細

這裏就貼一個demo代碼

springboot程序入口：

@SpringBootApplication

public class H_Main implements EmbeddedServletContainerCustomizer{
   public static void main(String[] args) {
          SpringApplication.run(H_Main.class, args);
          // 運行之後在瀏覽器中訪問：http://localhost:9999/hello
   }

   @Override
   public void customize (ConfigurableEmbeddedServletContainer arg0) {
       arg0.setPort(9999);
   }

}

實現EmbeddedServletContainerCustomizer接口，你可以自定義http訪問的端口，是不是很方便。。

下面是restful接口，由springboot初始化加載：

@Controller
@EnableAutoConfiguration
@RequestMapping("/apo")
public class ApolloConfigReadController {
ApolloConfigReadController apolloConfigReadController;

      @RequestMapping("/wyx")
      @ResponseBody
      String mywyx(){
          return "hello！hello! hello！";
      }

      @RequestMapping("/apollo")
      @ResponseBody
   public void apollotest(){
       Config config = ConfigService.getAppConfig(); //config instance is singleton for each namespace and is never null
       String someKey = "name";
       String someDefaultValue = "wbl";
       String value = config.getProperty(someKey, someDefaultValue);

       System.out.println("local-value"+value);

       System.out.println(config.getProperty("myname", null));


   }

   @RequestMapping("/sg")
   @ResponseBody
   public String setSg376(){
       System.out.println("前端訪問正常.");
        Config config = ConfigService.getConfig("protocolconfig");//namespace
       try {
               Properties prop2 = new Properties();

               apolloConfigReadController = new ApolloConfigReadController();

               URL url = apolloConfigReadController.getClass().getResource("");
               System.out.println(url.toString());

               InputStream in = ApolloConfigReadController.class.getClassLoader().getResourceAsStream("./config2.properties");
               prop2.load(in);
               Iterator<String> it=prop2.stringPropertyNames().iterator();
               System.out.println("本地配置讀取完成.");
               int countListt=0;
               String vval = "";
                while(it.hasNext()){
                   countListt=0;
                    String key=it.next();
//                    config.getProperty(key,prop2.getProperty(key));
                    vval = prop2.getProperty(key);

                    countListt=getCount(vval,"*");
                    if(countListt>6){
                       System.out.println("最多的*號個數是："+countListt);
                    }
                }
                in.close();
                System.out.println("配置寫入apollo服務端配置文件完成.");
           } catch (IOException e) {
               e.printStackTrace();
           }
       return "配置加載結束！";
   }

   public static int getCount(String str, String tag) {
       int index = 0;
       int count = 0;
       while ((index = str.indexOf(tag)) != -1 ) {
           str = str.substring(index + tag.length());
           count++;
       }
       return count;
   }

}
