spring boot整合dubbo

本项目通过模拟卖票和买票模块来讲解spring boot如何整合dubbo。

1.搭建zookeeper

使用docker方式：

docker pull registry.docker-cn.com/library/zookeeper

启动zookeeper

docker run --name zk01 -p 2181:2181  --restart always -d 06b178591ab3

2.新建卖票模块：provider-ticket

2.1配置pom

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.12.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.laoxu</groupId>
    <artifactId>provider-ticket</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>provider-ticket</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
        <dubbo.version>2.7.0</dubbo.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>com.alibaba.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>0.1.0</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/com.github.sgroschupf/zkclient -->
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.1</version>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

2.2创建service类

package com.laoxu.ticket.service;

public interface TicketService {
    public String getTicket();
}

package com.laoxu.ticket.service;

import com.alibaba.dubbo.config.annotation.Service;
import org.springframework.stereotype.Component;

@Component
@Service
public class TicketServiceImpl implements TicketService {

    @Override
    public String getTicket() {
        return "《厉害了，我的国》";
    }
}

2.3配置application.properties

dubbo.application.name=provider-ticket
dubbo.registry.address=zookeeper://221.194.44.221:2181
dubbo.scan.base-packages=com.laoxu.ticket.service

3.新建买票模块：consumer-user

3.1配置pom

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.12.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.laoxu</groupId>
    <artifactId>consumer-user</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>consumer-user</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>com.alibaba.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>0.1.0</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/com.github.sgroschupf/zkclient -->
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.1</version>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

3.2编写service

package com.laoxu.ticket.service;

public interface TicketService {
    public String getTicket();
}

package com.laoxu.user.service;

import com.alibaba.dubbo.config.annotation.Reference;
import com.laoxu.ticket.service.TicketService;
import org.springframework.stereotype.Service;

@Service
public class UserService {
    @Reference
    TicketService ticketService;

    public void hello(){
        String ticket = ticketService.getTicket();
        System.out.println("买到票了："+ticket);
    }
}

3.3编写单元测试

package com.laoxu.user;

import com.laoxu.user.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class ConsumerUserApplicationTests {
    @Autowired
    UserService userService;

    @Test
    public void contextLoads() {
        userService.hello();
    }

}

3.4配置application.properties

dubbo.application.name=consumer-user
dubbo.registry.address=zookeeper://221.194.44.221:2181

4.启动provider-ticket

5.运行consumer-user单元测试
