寫在前面：

使用springboot作為web框架，方便開發(fā)許多，做分布式開發(fā)，dubbo又不可少，那么怎么整合在一起呢，

跟我學(xué)一遍，至少會(huì)用

注意，springboot2.0和springboot1.x與dubbo整合不一樣，

1.環(huán)境

1.新建一個(gè)空的maven項(xiàng)目，作為父工程，新建moudle，，service（接口層，及實(shí)現(xiàn)層，沒有具體分，），web（web層，springboot項(xiàng)目）

項(xiàng)目結(jié)構(gòu)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>

        <artifactId>zkclient</artifactId>
        <version>0.1</version>
      </dependency>
    </dependencies>
  </dependencyManagement>

web層pom

 <dependencies>
    <dependency>
      <groupId>com.itzmn</groupId>
      <artifactId>dubbo-service</artifactId>
      <version>1.0-SNAPSHOT</version>

    </dependency>
  </dependencies>

2.接口設(shè)計(jì)

在service模塊新建接口，

接口實(shí)現(xiàn)類的注解，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層的配置文件中，配置，即可，前提，要先安裝zookeeper，才能進(jìn)行服務(wù)的注冊(cè)，然后啟動(dòng)即可

4.消費(fèi)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

只需將服務(wù)提供者的接口jar包引入，然后注入服務(wù)即可

注意，springboot2.0和springboot1.x與dubbo整合不一樣，

以上就是本文的全部內(nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持億速云。

向AI問一下細(xì)節(jié)
