3、新建UserInfoService接口

package com.demo.base.api;

import com.demo.base.pojo.UserInfoDTO;
import com.demo.base.pojo.UserInfoVO;

public interface UserInfoService {

    UserInfoVO getUserInfo(UserInfoDTO dto);

    UserInfoVO getUserInfoById(Long id);
}

4、新建POJO UserInfoDTO和UserInfoVO

package com.demo.base.pojo;

import java.io.Serializable;

public class UserInfoDTO implements Serializable {

    /**
     * id
     */
    private Long id;

    /**
     * 名字
     */
    private String name;

    /**
     * 性别
     */
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }
}

package com.demo.base.pojo;

import java.io.Serializable;

public class UserInfoVO implements Serializable {

    /**
     * id
     */
    private Long id;

    /**
     * 名字
     */
    private String name;

    /**
     * 性别
     */
    private int age;

    /**
     * 地址
     */
    private String address;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }
}

新建provider-service工程

1、New Module，新建provider-service ，dubbo提供者

pom文件内容

<?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">

        </dependency>

        <dependency>

                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>

                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

2、application.properties

server.port=8081

# dubbo
dubbo.application.name=provider-service-01
# zookeeper 填写自己的zookeeper ip
dubbo.registry.address=your zookeeper ip:port
dubbo.registry.protocol=zookeeper
# 可以不配置monitor
# dubbo.monitor.protocol=registry

3、ProviderServiceApplication需要添加@EnableDubbo注解

package com.springboot.demo.provider;

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

@EnableDubbo
@SpringBootApplication
public class ProviderServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(ProviderServiceApplication.class, args);
    }

}

4、UserInfoServiceImpl 接口实现类的@Service要注意，这个是dubbo的注解类，要和spring的区分

package com.springboot.demo.provider.user;

import com.alibaba.dubbo.config.annotation.Service;
import com.demo.base.api.UserInfoService;
import com.demo.base.pojo.UserInfoDTO;
import com.demo.base.pojo.UserInfoVO;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

@Service
@Component
public class UserInfoServiceImpl implements UserInfoService {

    private static final Logger logger = LoggerFactory.getLogger(UserInfoServiceImpl.class);

    @Override
    public UserInfoVO getUserInfo(UserInfoDTO dto) {

        UserInfoVO vo = new UserInfoVO();
        vo.setId(dto.getId());
        vo.setAge(dto.getAge());
        vo.setName(dto.getName());
        vo.setAddress("清华大学");
        return vo;
    }

    @Override
    public UserInfoVO getUserInfoById(Long id) {
        UserInfoVO vo = new UserInfoVO();
        vo.setId(id);
        vo.setAge(20);
        vo.setName("小明");
        vo.setAddress("北京大学");
        return vo;
    }
}

新建consumer-service工程

1、New Module，新建consumer-service，dubbo消费者

2、pom文件内容

<?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">

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.springboot.demo</groupId>
    <artifactId>consumer-service</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>consumer-service</name>
    <description>Consumer Service Demo project for Spring Boot</description>

    <dependencies>
        <dependency>

        </dependency>

        <dependency>
            <groupId>com.springboot.demo</groupId>
            <artifactId>base-api</artifactId>

        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

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

</project>

2、application.properties

server.port=8082

# dubbo
dubbo.application.name=consumer-service-01
# zookeeper 填写自己的zookeeper ip
dubbo.registry.address=your zookeeper ip:port
dubbo.registry.protocol=zookeeper
# 可以不配置monitor
# dubbo.monitor.protocol=registry

3、ConsumerServiceApplication需要添加@EnableDubbo注解

package com.springboot.demo.consumer;

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

@EnableDubbo
@SpringBootApplication
public class ConsumerServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConsumerServiceApplication.class, args);
    }
}

4、POJO  客户信息入参UserInfoParam

package com.springboot.demo.consumer.pojo;

import java.io.Serializable;

/**
 * @Description 客户信息入参
 * @Author lz.wang
 * @Since 1.0
 * @Date 2019/11/19
 */
public class UserInfoParam implements Serializable {

    /**
     * id
     */
    private Long id;

    /**
     * 名字
     */
    private String name;

    /**
     * 性别
     */
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }
}

5、客户信息控制层   UserInfoController，使用@Reference注解时，需要注意其属性，比如配置@Reference(retries = 0, timeout = 10000)，为默认不重试，超时时间为10秒。

package com.springboot.demo.consumer.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.demo.base.api.UserInfoService;
import com.demo.base.pojo.UserInfoDTO;
import com.demo.base.pojo.UserInfoVO;
import com.springboot.demo.consumer.pojo.UserInfoParam;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @Description 客户信息控制层
 * @Author lz.wang
 * @Since 1.0
 * @Date 2019/11/19
 */
@RestController
public class UserInfoController {

    //忽略启动校验，与@Service配合
    @Reference(check=false)
    private UserInfoService userInfoService;


    @RequestMapping("/getUserInfoById")
    public UserInfoVO getUserInfoById(Long id){

        return userInfoService.getUserInfoById(id);
    }

    @RequestMapping("/getUserInfo")
    public UserInfoVO getUserInfo(UserInfoParam userInfoParam){

        UserInfoDTO dto = new UserInfoDTO();
        dto.setId(userInfoParam.getId());
        dto.setName(userInfoParam.getName());
        dto.setAge(userInfoParam.getAge());
        return userInfoService.getUserInfo(dto);
    }

}

启动项目

1、先启动提供者，再启动消费者

2、查看dubbo admin，服务是否注册成功

3、在浏览器上输入请求地址：http://localhost:8082/getUserInfo?id=2&name=喵喵&age=15，结果如下图，则调用成功。

以上Springboot整合Dubbo实例完成，可以根据自己的需要，添加其他Dubbo配置
