+### Group Aggregation
+
+> Reference Example
+[https://github.com/apache/dubbo-samples/tree/master/2-advanced/dubbo-samples-merge](https://github.com/apache/dubbo-samples/tree/master/2-advanced/dubbo-samples-merge)
+
+```java
+// Group aggregation, merging all groups and returning the result
+@DubboReference(group = "*", merger = "true")
+private DemoService demoService2;
+
+// Group aggregation, merging specified groups and returning the result
+@DubboReference(group = "merge,merge2", merger = "true")
+private DemoService demoService2;
+```
+
 After starting the Dubbo service, you can see the references of the same 
service name in different groups in the registration center. Taking Nacos as 
the registration center as an example, the following content is displayed:

+#### 分组聚合
+
+> 参考用例
+[https://github.com/apache/dubbo-samples/tree/master/2-advanced/dubbo-samples-merge](https://github.com/apache/dubbo-samples/tree/master/2-advanced/dubbo-samples-merge)
+
+```java
+// 分组聚合，对所有分组进行merge后返回
+@DubboReference(group = "*", merger = "true")
+private DemoService demoService2;
+
+// 分组聚合，对指定分组进行merge后返回
+@DubboReference(group = "merge,merge2", merger = "true")
+private DemoService demoService2;
+
+```
+
 同样启动 Dubbo 服务后，可在注册中心看到相同服务名不同分组的引用者，以 Nacos 作为注册中心为例，显示如下内容：
