一、创建公共依赖dubbo-dependencies

1. 创建工程dubbo-dependencies，pom.xml文件如下

<?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>

    <groupId>com.zsx</groupId>
    <artifactId>dubbo-dependencies</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>pom</packaging>

    <name>dubbo-dependencies</name>
    <description>Dubbo Dependencies</description>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>11</java.version>
        <dubbo.version>2.7.3</dubbo.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.apache.dubbo</groupId>
                <artifactId>dubbo-dependencies-bom</artifactId>
                <version>${dubbo.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>
        <dependency>
            <groupId>org.apache.dubbo</groupId>
            <artifactId>dubbo</artifactId>
            <version>${dubbo.version}</version>
        </dependency>
        <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-all</artifactId>
        </dependency>
    </dependencies>

</project>

二、创建公共接口

1. 创建工程

dubbo-interface，pom.xml文件如下

<?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>

    <groupId>com.zsx</groupId>
    <artifactId>dubbo-interface</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>dubbo-interface</name>
    <description>Dubbo Interface</description>

</project>

2. 编写公共服务接口类

package com.zsx.service;

public interface UserService {

    String get(String msg);
}

三、创建服务提供者

1. 创建工程dubbo-provide，pom.xml文件如下

<?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>

    <groupId>com.zsx</groupId>
    <artifactId>dubbo-provider</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>dubbo-provider</name>
    <description>Dubbo Provider</description>

        <javassist.version>3.25.0-GA</javassist.version>
        <dubbo-registry-redis.version>2.7.3</dubbo-registry-redis.version>
    </properties>
    <parent>
        <groupId>com.zsx</groupId>

        </dependency>
        <!--<dependency>

            <version>${dubbo-registry-redis.version}</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

2. 编写配置文件src/main/resource/com/zsx/dubbo-provider.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
       http://dubbo.apache.org/schema/dubbo
       http://dubbo.apache.org/schema/dubbo/dubbo.xsd">

    <!-- 提供方应用信息，用于计算依赖关系 -->
    <dubbo:application name="provider-server"/>

    <!-- 配置中心 -->
    <dubbo:config-center address="zookeeper://127.0.0.1:2181" />
    <!-- 使用zookeeper注册中心暴露服务地址 -->
    <dubbo:registry address="zookeeper://127.0.0.1:2181" simplified="true" />

    <!--<dubbo:metadata-report address="redis://127.0.0.1:6379" />-->

    <!-- 用dubbo协议在20880端口暴露服务 -->
    <dubbo:protocol name="dubbo" port="20880"/>

    <!-- 和本地bean一样实现服务 -->
    <bean id="userService" class="com.zsx.service.impl.UserServiceImpl" />

    <!-- 声明需要暴露的服务接口 -->
    <dubbo:service interface="com.zsx.service.UserService" ref="userService" />

</beans>

3. 编写日志文件src/main/resources/log4j.properties

###set log levels###
log4j.rootLogger=info, stdout
###output to console###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d{dd/MM/yy HH:mm:ss:SSS z}] %t %5p %c{2}: %m%n

4. 编写src/main/resources/dubbo.properties配置文件

dubbo.application.qos.port=22222

5. 创建接口对应的实现

package com.zsx.service.impl;

import com.zsx.service.UserService;
import org.apache.dubbo.rpc.RpcContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class UserServiceImpl implements UserService {

    private static final Logger LOGGER = LoggerFactory.getLogger(UserServiceImpl.class);

    @Override
    public String get(String msg) {
        LOGGER.info("The message content is : %s, Service address is : %s", msg, RpcContext.getContext().getLocalAddress());
        return String.format("The message content is : %s, Service address is : %s", msg, RpcContext.getContext().getLocalAddress());
    }
}

6. 创建主程序启动类

package com.zsx;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.io.IOException;

public class ProviderApplication {

    public static void main(String[] args) throws IOException {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"com/zsx/dubbo-provider.xml"});
        context.start();
        System.in.read(); // 按任意键退出
    }
}

7. 启动服务提供者

2. 编写配置文件src/main/resource/com/zsx/dubbo-consumer.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
       http://dubbo.apache.org/schema/dubbo
       http://dubbo.apache.org/schema/dubbo/dubbo.xsd">

    <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
    <dubbo:application name="consumer-server"  />

    <!-- 使用zookeeper注册中心暴露发现服务地址 -->
    <dubbo:registry check="false" address="zookeeper://127.0.1.1:2181" />

    <!-- 生成远程服务代理，可以和本地bean一样使用userService -->
    <dubbo:reference id="userService" interface="com.zsx.service.UserService" />
</beans>

3. 编写日志文件src/main/resources/log4j.properties

###set log levels###
log4j.rootLogger=info, stdout
###output to the console###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d{dd/MM/yy HH:mm:ss:SSS z}] %t %5p %c{2}: %m%n

4. 编写src/main/resources/dubbo.properties配置文件

dubbo.application.qos.port=33333

5. 创建主程序启动类

package com.zsx;

import com.zsx.service.UserService;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ConsumerApplication {

    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("com/zsx/dubbo-consumer.xml");
        context.start();
        UserService userService = (UserService)context.getBean("userService"); // 获取远程服务代理
        String msg = userService.get("hello world"); // 执行远程方法
        System.out.println( msg ); // 显示调用结果
    }
}

6. 启动服务提供者后，再启动消费者
