*  ### 创建服务接口项目(maven或java项目即可) ###
    
    1.  pom.xml文件(这里使用了lombok插件，有兴趣的可以点击[lombok][idea_lombok]阅读安装使用)
        
            <?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.dubbo</groupId>
                <artifactId>service</artifactId>
                <version>1.0-SNAPSHOT</version>
            
                <dependencies>
                    
                    <dependency>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>
                        <version>1.18.8</version>
                        <optional>true</optional>
                    </dependency>
                </dependencies>
            </project>
    2.  创建数据模型
        
            import lombok.Getter;
            import lombok.Setter;
            import lombok.ToString;
            
            import java.io.Serializable;
            
            @Getter
            @Setter
            @ToString
            public class ResultModel implements Serializable { 
            
                private String name;
            
                private Integer age;
            
            }
    3.  创建接口类
        
            import com.dubbo.model.ResultModel;
            
            public interface DubboTestService { 
            
                public ResultModel getTestResult();
            }
    4.  使用mvn clean install命令打包，创建完成，完整结构如图

*  ### 创建服务实现项目(springBoot)，基于注解方式 ###
    
    1.  pom.xml文件
        
            <?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">

                </properties>
            
                <dependencies>
                    <dependency>
                        <groupId>org.springframework.boot</groupId>

                </dependencies>
            
                <build>
                    <plugins>
                        <plugin>
                            <groupId>org.springframework.boot</groupId>
                            <artifactId>spring-boot-maven-plugin</artifactId>
                        </plugin>
                    </plugins>
                </build>
            
            </project>
    2.  springBoot启动类增加@EnableDubbo注解  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 1]
    3.  application.properties配置文件增加以下dubbo配置
        
        > \#提供方应用信息，用于计算依赖关系  
        > dubbo.application.name=dubboTest  
        > \#使用zookeeper注册中心  
        > dubbo.registry.address=zookeeper://127.0.0.1:2181  
        > \#用dubbo协议在20880端口暴露服务  
        > dubbo.protocol.name=dubbo  
        > dubbo.protocol.port=20880  
        > ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 2]
    4.  添加服务提供类，**注意:**  
        **1、@Service注解是dubbo提供的不是spring提供的**  
        **2、DubboTestService接口是第一个项目编写的，由服务提供者实现**  
        **3、@Service注解增加interfaceClass参数是防止这个类使用了其他AOP使dubbo无法正常解析接口类**  
        **4、group参数用于区分环境**  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 3]
    5.  启动项目后可以在dubbo-admin后台看到  
        ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI1MjE1ODIx_size_16_color_FFFFFF_t_70 4]

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

*  ### 基于XML方式(使用注解方式的pom.xml文件) ###
    
    1.  创建XML配置文件
        
            <?xml version="1.0" encoding="UTF-8"?>
            <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns="http://www.springframework.org/schema/beans" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
            
                
                <dubbo:application name="dubboTest"/>
            
                
                <dubbo:registry address="zookeeper://127.0.0.1:2181"/>
            
                
                <dubbo:protocol name="dubbo" port="20880"/>
            
                
                <bean id="DubboTestServiceImpl" class="com.dubbo.service.impl.DubboTestServiceImpl" />
            
                
                <dubbo:service interface="com.dubbo.service.DubboTestService" ref="DubboTestServiceImpl" group="test" version="1.0.0"/>
            </beans>
    2.  创建启动类
        
            import org.springframework.context.support.ClassPathXmlApplicationContext;
            import java.io.IOException;
            
            public class ServiceImplApplication { 
            
                public static void main(String[] args) throws IOException { 
                    ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("serviceImpl.xml");
                    context.start();
                    System.out.println("----------------服务已启动，按任意键结束···········--------------------");
                    System.in.read(); 
                }
            
            }
