写在前面：
使用springboot作为web框架，方便开发许多，做分布式开发，dubbo又不可少，那么怎么整合在一起呢，
跟我学一遍，至少会用
注意，springboot2.0和springboot1.x与dubbo整合不一样，
1.环境
1.新建一个空的maven项目，作为父工程，新建moudle，，service（接口层，及实现层，没有具体分，），web（web层，springboot项目）
项目结构如下

父pom如下
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>

<!--如果要把springboot工程打包成war执行，需要该jar-->

web层pom

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

<dependency>

2.接口设计

在service模块新建接口，

接口实现类的注解，service一定是dubbo的注解
3.配置文件
# Spring boot application
spring.application.name = /springboot-dubbo
server.port = 9099
management.port = 9091
# Service version
demo.service.version = 1.0.0
# Base packages to scan Dubbo Components (e.g @Service , @Reference)
dubbo.scan.basePackages = com.itzmn.dubbo.service.impl
# Dubbo Config properties
## ApplicationConfig Bean
dubbo.application.id = springboot-dubbo
dubbo.application.name = springboot-dubbo
## ProtocolConfig Bean
dubbo.protocol.id = dubbo
dubbo.protocol.name = dubbo
dubbo.protocol.port = 20880
## RegistryConfig Bean
dubbo.registry.id = my-registry1
dubbo.registry.address = zookeeper://47.106.64.158:2181
在web层的配置文件中，配置，即可，前提，要先安装zookeeper，才能进行服务的注册，然后启动即可
4.消费者
配置
# Spring boot application
spring.application.name = dubbo-consumer-demo
server.port = 8080
management.port = 8081
# Service Version
demo.service.version = 1.0.0
# Dubbo Config properties
## ApplicationConfig Bean
dubbo.application.id = dubbo-consumer-demo
dubbo.application.name = dubbo-consumer-demo
## ProtocolConfig Bean
dubbo.protocol.id = dubbo
dubbo.protocol.name = dubbo
dubbo.protocol.port = 12345
只需将服务提供者的接口jar包引入，然后注入服务即可
注意，springboot2.0和springboot1.x与dubbo整合不一样，
