spring boot 已有项目不修改代码通过配置整合dubbo和nacos实现微服务改造

一、已有项目采用maven多模块方式开发的，通过引入dubbo进行微服务改造

　　(1) 使用注解自动扫描的方式，需要在开发好的代码中增加注解，涉及到部分代码改造

　　(2) 采用xml配置的方式新增模块，在不改动任何现有代码的情况下实现微服务改造

　　由于我改造的是已经开发好的项目，为了避免对代码进行大的改动，使用第二种方式进行

 

二、引入dubbo和nacos注册中心相关的jar包，进行微服务改造

　（1）在服务提供方和消费方都引入以下包，一定要保证dubbo和nacos相关的包版本正确，否则在注册中心可以看到注册的服务，但是调用不一定成功

<!-- dubbo的依赖 -->
<!-- https://mvnrepository.com/artifact/org.apache.dubbo/dubbo-spring-boot-starter -->
<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo-spring-boot-starter</artifactId>
    <version>2.7.7</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.dubbo/dubbo-registry-nacos -->
<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo-registry-nacos</artifactId>
    <version>2.7.7</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.alibaba.boot/nacos-config-spring-boot-starter -->

    <artifactId>nacos-config-spring-boot-starter</artifactId>
    <version>0.2.7</version>
</dependency>
<!-- dubbo的依赖 -->

 

（2）服务提供方配置文件中增加dubbo及注册中心nacos相关的配置

• 　　在服务提供端application.yml中增加以下配置

dubbo:
  application:
    name:  wdapi-provider
  protocol:
    port: -1
    name: dubbo
  registry:
　　 address: nacos://127.0.0.1:8848
    # 可换为zookeeperip
    check: false
  monitor:
    protocol: register
  consumer:
    check:  false
    timeout: 3000

 

• 在服务提供方模块下增加dubbo-provider.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"

    <!--1、指定当前服务/应用的名字（同样的服务名字相同，不要和其它的服务同名）-->
    <dubbo:application name="wdapi-provider"/>

    <!--2、指定注册中心的位置（注册中心不同，服务地址的写法不同）-->
    <!--<dubbo:registry address="redis://192.168.205.128:6379"/>-->
<!--    <dubbo:registry address="zookeeper://192.168.205.128:2181"/>-->

    <!--4、声明需要暴露的服务接口，ref属性要指向容器中的接口实现对象-->

• 在服务启动方启动类中增加相关配置

 

 

（3）服务消费方配置文件中增加dubbo及注册中心nacos相关的配置

• 　　在服务消费端application.yml中增加以下配置

dubbo:
  application:
    name:  wdapi-consumer
  protocol:
    port: -1
    name: dubbo
  registry:
    address: nacos://127.0.0.1:8848
    # 可换为zookeeper  zookeeperip
    check: false
  monitor:
    protocol: register
  consumer:
    check:  false
    timeout: 3000

 

 

• 在服务消费方模块下增加dubbo-consumer.xml配置文件

    <!--1、指定当前服务/应用的名字（同样的服务名字相同，不要和其它的服务同名）-->
<!--    <dubbo:application name="wdapi-consumer"/>-->
    <dubbo:application name="wdapi-consumer" >
        <dubbo:parameter key="qos.enable" value="true" />
        <dubbo:parameter key="qos.accept.foreign.ip" value="false" />
        <dubbo:parameter key="qos.port" value="33333" />
    </dubbo:application>

<!--    <dubbo:registry address="nacos://127.0.0.1:8848"/>-->

    <!--2、声明需要暴露的服务接口，ref属性要指向容器中的接口实现对象-->
    <dubbo:reference id="userService" interface="com.wonders.hrpms.auth.service.UserService" group="dubbo"/>

    <dubbo:reference id="apiBusinessService" interface="com.wonders.hrpms.auth.service.ApiBusinessService" group="dubbo"/>

    <dubbo:reference id="entranceService" interface="com.wonders.wdapi.service.EntranceService" group="dubbo"/>
</beans>

 

• 在服务消费方启动类中增加相关配置

 

 

三、启动服务提供方和服务消费方服务，在nacos注册中心就可以看到相关的服务
