springboot2.x集成dubbo （支持不同group不

1、在pom中引入dubbo的依赖

<dependency>   

    <groupId>com.alibaba.spring.boot</groupId>   

    <artifactId>dubbo-spring-boot-starter</artifactId> 

   <version>2.0.0</version>

</dependency>

2、在配置文件中配置dubbo的注册中心

(1)简单配置

spring.dubbo.application.id=order

spring.dubbo.application.name= order

spring.dubbo.registry.address= zookeeper://192.168.1.1:2181?backup= 192.168.1.2 :2181, 192.168.1.3 :2181  

(2)消费者和提供者group、注册中心不同的配置

spring.dubbo.application.id=order

spring.dubbo.application.name= order

spring.dubbo.registries.orderCenter.group=order

spring.dubbo.registries.orderCenter.address= zookeeper://192.168.1.1:2181?backup= 192.168.1.2 :2181, 192.168.1.3 :2181  

spring.dubbo.registries.userCenter.group=user

spring.dubbo.registries.busTicket.address=zookeeper://192.168.1.1:2181?backup= 192.168.1.2 :2181, 192.168.1.3 :2181 

spring.dubbo.provider.filter=dubboServiceFilter

   spring.dubbo.consumer.filter=dubboServiceFilter

dubbo的过滤器配置最后面会讲dubboServiceFilter 

3、发布dubbo接口（ registry 指定的是上面不同group的方式 ）

@Service(registry = "orderCenter") 

@Component 

public class OrderService{ 

.....

}

service 注解用的是com.alibaba.dubbo.config.annotation.Service

4、引用dubbo方式

@Reference(registry = "userCenter", interfaceClass = IUserService.class, timeout = 15000, retries = 0, check = false)

 UserService   userService;

reference注解用的是com.alibaba.dubbo.config.annotation.Reference

5、案列
