dubbo 2.7 spring-boot starter 多註冊中心寫法

踩了太多坑，官網中文參考地址：http://dubbo.apache.org/zh-cn/index.html

話不多說，直接懟代碼

dubbo 2.7.x 的 boot starter寫法如下

依賴：

<dubbo.version>2.7.1</dubbo.version>

    dubbo:
    #  registry: # 單註冊中心,注意屬性級別:dubbo.registry,如果有@Service(registry = {"registry1","registry2","registry3"}),則刪除
    #    register: false # true(默認), false:表示服務不註冊到註冊中心(只訂閱,直連服務正常),且dubbo-admin不顯示
    #    address: zookeeper://127.0.0.1:2181
      registries: # 多註冊中心,注意屬性級別:dubbo.registries, 不同的方法可以用@Service(registry = {"registry2"}),指定不同的註冊中心
        provider1:
          register: true #默認,false:表示服務不註冊到註冊中心
          address: zookeeper://a.a.a.a:2181

      provider:
        retries: 0        # 服務提供者無需重試
        timeout: 6000     # 默認只有1s

 provider-bean:
    bean1註解:
        @Service(group = "project1", version = "1.0.0", registry = {"provider1", "provider3"}
        public class DubboPrintServiceImpl implements DubboPrintService{...}
    bean2註解:
        @Service(group = "project2", version = "2.0.0", registry = {"provider3"})
        public class DubboPrintService2Impl implements DubboPrintService{...}

消費者 comsumer:

---------------------- consumer ----------------------
 consumer-yaml:
    dubbo:
    #  registry: # 單註冊中心,注意屬性級別:dubbo.registry
    #    register: false # true(默認), false:表示服務不註冊到註冊中心(只訂閱,直連服務正常),且dubbo-admin不顯示

        timeout: 3000
        check: true   # 服務啓動時候檢查是否可用
        retries: 2    # 服務重試次數
 
 consumer-bean:
    下面的Bean注入後,直接使用
    @Reference(group = "project1", version = "1.0.0", registry = {"consumer1", "consumer3"})
    private DubboPrintService printService1;

    @Reference(group = "project2", version = "2.0.0", registry = {"consumer2"})
    private DubboPrintService printService2;
