SpringBoot整合Dubbo + ZooKeeper

0、借鉴 狂神说SpringBoot17：Dubbo和Zookeeper集成

1、Zookeeper下载与安装

Zookeeper下载与安装教程（for windows）

2、pom

<!-- Dubbo Spring Boot Starter -->
        <dependency>
            <groupId>org.apache.dubbo</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>2.7.3</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/com.github.sgroschupf/zkclient -->
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.1</version>
        </dependency>
        <!-- 引入zookeeper -->
        <dependency>
            <groupId>org.apache.curator</groupId>
            <artifactId>curator-framework</artifactId>
            <version>2.12.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.curator</groupId>
            <artifactId>curator-recipes</artifactId>
            <version>2.12.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.14</version>
            <!--排除这个slf4j-log4j12-->
            <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-log4j12</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

3、application.properties

springboot-provider

server.port=8081
#当前应用名字
dubbo.application.name=provider-server
#注册中心地址
dubbo.registry.address=zookeeper://127.0.0.1:2181
#扫描指定包下服务
dubbo.scan.base-packages=com.service.TicketService

springboot-consumer

server.port=8082

#当前应用名字
dubbo.application.name=consumer-server
#注册中心地址
dubbo.registry.address=zookeeper://127.0.0.1:2181

4、@EnableDubbo

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableDubbo
@SpringBootApplication
public class ProviderApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProviderApplication.class, args);
    }
}

5、代码 com.service.TicketService 生产者和消费者包名要一致

springboot-provider

public interface TicketService {
    public String getTicket();
}

import org.apache.dubbo.config.annotation.Service;
import org.springframework.stereotype.Component;

------------------------------------------------------------------------------------------

@Service //将服务发布出去
@Component //放在容器中
public class TicketServiceImpl implements TicketService {
    @Override
    public String getTicket() {
        return "getTicket";
    }
}

springboot-consumer

import com.service.UserService;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@EnableDubbo
@SpringBootTest
class SpringbootConsumerApplicationTests {
    @Autowired
    UserService userService;
    @Test
    void contextLoads() {
        userService.bugTicket();
    }
}


------------------------------------------------------------------------------------

public interface TicketService {
    public String getTicket();
}
