spring boot 集成dubbo的示例演示

本demo使用spring boot 2.4.1版本集成 dubbo 2.7.15

1.创建maven项目及其子模块

父工程pom.xml

<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">

        <type>pom</type>

        <scope>import</scope>

      </dependency>

    </dependencies>

  </dependencyManagement>

</project>

2.其中coupon-service-api为接口

3.coupon-service-provider为接口实现类，注意，其启动类需要添加注解@EnableDubbo

</project>

配置文件

实现类添加注解@DubboService

4.coupon-portal为web访问层，配置如下

                </executions>

            </plugin>

        </plugins>

    </build>

</project>

启动类

 controller访问层，属性注入时，如果为RPC调用，则需要添加注解@DubboReference

5.依次启动接口提供者（springboot项目）

coupon-service-provider、user-service-provider以及web层coupon-portal

6.前端访问：127.0.0.1:8080/coupon

 

至此完成了springboot 2.4.1集成 dubbo 2.7.15
