先准备zookeeper。下载解压后进入bin目录点击zkServer.cmd启动。这里不多说了，百度一大堆。
新建一个Maven项目
下面是父工程的pom.xml

引入上面的这些依赖后再来看下dubbo-api工程
首先看一下dubbo-api中的pom.xml
com.st
1.0-SNAPSHOT
4.0.0
jar
dubbo-api
springBoot_Dubbo_API
org.springframework.boot
spring-boot-starter-parent
2.0.4.RELEASE

1.8
org.springframework.boot
spring-boot-starter
org.springframework.boot
spring-boot-starter-test
test
org.springframework.boot
spring-boot-maven-plugin
引入上面的依赖后创建公共的实体（一定要序列化）和接口
下面是User实体代码
package com.st.sang.entity;
import java.io.Serializable;
/**
* @author SangJx
* @description 用户实体
* @date 2019/6/26 2:13
*/
public class User implements Serializable {
private static final long serialVersionUID = -1688765204850364609L;
private Integer id;
private String userName;
private String passWord;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
}
下面是UserService代码，这里就只写一个接口
package com.st.sang.service;
import com.st.sang.entity.User;
import java.util.List;
public interface UserService {
List getAllUser();
}
到这里父工程和dubbo-api就写完了，下面就是服务提供者dubbo-provider和消费者dubbo-consumer
先展示下dubbo-privoder模块结构
下面是dubbo-provider的pom.xml文件
4.0.0
com.st
dubbo-provider
1.0-SNAPSHOT
jar
springBoot_Dubbo_Provider
org.springframework.boot
spring-boot-starter-parent

org.springframework.boot
spring-boot-starter-test
test
com.alibaba

org.mybatis.spring.boot
mybatis-spring-boot-starter

spring-boot-starter-jdbc
mysql
mysql-connector-java
5.1.35
com.alibaba
druid
1.0.11
org.springframework.boot
spring-boot-maven-plugin
接下来是application.yml，没有这个文件的朋友可以把默认创建的application.properties文件删了，在resource上右键新建file
server:
port: 8082
servlet:
context-path: /
spring:
datasource:
name: test
url: jdbc:mysql://127.0.0.1:3306/st
username: root
password: root
# 使用druid数据源
type: com.alibaba.druid.pool.DruidDataSource
driver-class-name: com.mysql.jdbc.Driver
filters: stat
maxActive: 20
initialSize: 1
maxWait: 60000
minIdle: 1
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
maxOpenPreparedStatements: 20
#Mybatis配置
mybatis:
typeAliasesPackage: com.st.sang.entity
mapperLocations: classpath:mapper/*.xml
#打印Mybatis的sql语句
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
这里我们改一下端口号提供者为8082，消费者为8081，并配置druid数据库连接池和Mybatis
然后我们在resource文件夹下新建一个下xml文件，spring-dubbo.xml在项目启动的时候去加载，让此项目作为服务提供者
配置完以上这些就可以写服务提供者接口实现和dao层了
package com.st.sang.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
import com.st.sang.entity.User;
import com.st.sang.mapper.UserMapper;
import com.st.sang.service.UserService;
import javax.annotation.Resource;
import java.util.List;
/**
* @author SangJx
* @description
* @date 2019/6/26 2:44
*/
@Service(timeout = 10000)
public class UserServiceImpl implements UserService {
@Resource
private UserMapper userMapper;
public List getAllUser() {
List userList = userMapper.getAllUser();
return userList;
}
}
这里的@Service注解一定要注意是dubbo的，接下来在UserMapper中定义一个查询所有用户接口
package com.st.sang.mapper;
import com.st.sang.entity.User;
import java.util.List;
public interface UserMapper {
List getAllUser();
}
然后在UserMapper.xml中写sql
id, userName, passWord
最后一步是完成dubbo-provider的启动类DubboProviderApplication
package com.st.sang;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
import java.io.IOException;
/**
* @author SangJx
* @description 启动类
* @date 2019/6/26 2:50
*/
@SpringBootApplication
@ImportResource("classpath:spring-dubbo.xml")
@MapperScan("com.st.sang.mapper")
public class DubboProviderApplication {
public static void main(String[] args){
SpringApplication.run(DubboProviderApplication.class,args);
System.out.println("服务端启动成功！！！！！！！！！！！！！！");
try {
System.in.read();
} catch (IOException e) {
e.printStackTrace();
}
}
}
到这里dubbo-provider模块结束，下面是消费者模块，同样先来看下目录结构
在pom.xml中添加需要的依赖
4.0.0
com.st
dubbo-consumer
1.0-SNAPSHOT
jar
springBoot_Dubbo_Consumer
org.springframework.boot
spring-boot-starter-parent
2.0.4.RELEASE
UTF-8
UTF-8
1.8
2.5.5
0.10
com.st
dubbo-api
1.0-SNAPSHOT
org.springframework.boot
spring-boot-starter
org.springframework.boot
spring-boot-starter-test
test
org.springframework.boot
spring-boot-starter-web
com.alibaba
dubbo
${dubbo.version}
log4j
log4j
com.101tec
zkclient
${zkClient.version}
org.springframework.boot
spring-boot-maven-plugin
然后我们需要在resource目录下创建spring-dubbo.xml，让此模块成为一个消费者
配置完spring-dubbo后，书写controller来调用服务
package com.st.sang.controller;
import com.alibaba.dubbo.config.annotation.Reference;
import com.st.sang.entity.User;
import com.st.sang.service.UserService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
/**
* @author SangJx
* @description
* @date 2019/6/26 12:36
*/
@RestController
public class UserController {
@Reference
UserService userService;
@RequestMapping("/getAllUser")
public List getAllUser(){
System.out.println("进来了！！！！！！！！！");
List list = userService.getAllUser();
return list;
}
}
这里使用@Reference注解注入接口，@Refence一般用来注入分布式的远程服务对象，配合dubbo使用。
最后我们给dubbo-consumer模块添加启动类，springBoot的程序入口DubboConsumerApplication
package com.st.sang;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
/**
* @author SangJx
* @description 消费者启动类
* @date 2019/6/26 12:35
*/
@SpringBootApplication
@ImportResource("classpath:spring-dubbo.xml")
public class DubboConsumerApplication {
public static void main(String[] args){
SpringApplication.run(DubboConsumerApplication.class,args);
System.out.println("消费端启动成功！！！！");
}
}
至此，所有的模块dubbo-api、dubbo-provider、dubbo-consumer都已书写完毕，另外User表的建表语句
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
`userName` varchar(255) DEFAULT NULL COMMENT '用户名',
`passWord` varchar(255) DEFAULT NULL COMMENT '密码',
`roleList` varchar(255) DEFAULT NULL COMMENT '角色',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
让我们测试一下，先启动dubbo-provider，然后启动dubbo-consumer，使用postman发送一下请求
可以看到，我们从数据库中查出的数据，服务消费成功。
