1.新建普通maven工程

2.在父级pom中按需修改

3.删除父级src目录

4.创建公共模块common,里面只有service接口和实体类

5.构建微服务模块,provider

6.引用Zookeeper和Dubbo的依赖

在这个provider中修改pom文件坐标

  <dependencies>
        <!--引入公共模块项目-->
        <dependency>
            <groupId>cn.kgc</groupId>
            <artifactId>common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <!--这是微服dubbo的核心服务包-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.5.3</version>
            <exclusions>
                <exclusion>
                    <artifactId>spring</artifactId>
                    <groupId>org.springframework</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <!--这是zookeeper的服务操作包 但主要这里的版本最好和你的zookeeper版本一致-->
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.6</version>
            <exclusions>
                <exclusion>
                    <artifactId>slf4j-log4j12</artifactId>
                    <groupId>org.slf4j</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <!--这里是zookeeper的zkCli的操作包 我们读写服务全靠这个包-->
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.1</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.2</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.38</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

7.在provider中写mapper和service的实现

8.在启动类上添加mapper扫描注解

9.在resources下建这两个文件,用于注册

9.1application.properties

修改需要的url参数和分页插件参数

server.port=9090

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/kgc
spring.datasource.username=root
spring.datasource.password=ok

mybatis.type-aliases-package=cn.kgc.vo

mybatis.mapper-locations=mapper/*.xml

pagehelper.helper-dialect=mysql

9.2spring-provider.xml

根据需要修改用户服务接口中的参数,作用是将service的接口注入到Zookeeper中去

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                          http://www.springframework.org/schema/beans/spring-beans.xsd
                          http://code.alibabatech.com/schema/dubbo
                          http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <!-- 提供方应用信息，用于计算依赖关系 -->
    <dubbo:application name="myprovider" />

    <!-- 使用zookeeper注册中心暴露服务地址,我的zookeeper是架在本地的 -->
    <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" timeout="60000"/>

    <!-- 用dubbo协议在20880端口暴露服务 -->
    <dubbo:protocol name="dubbo" port="20880" />

    <!-- 用户服务接口 -->
    <dubbo:service interface="cn.kgc.service.TableToOneService" ref="tableToOneService"/>
    <bean id="tableToOneService" class="cn.kgc.service.TableToOneServiceImpl"/>

    <dubbo:service interface="cn.kgc.service.TableToManyService" ref="tableToManyService"/>
    <bean id="tableToManyService" class="cn.kgc.service.TableToManyServiceImpl"/>
</beans>

10再修改启动项,添加导入资源注解

11再创建微服务模块,consumer

12.把provider中pom的坐标拷贝到consumer

13.把provider中的application文件拷贝到consumer,并按需修改(端口号等)

14.编写controller类和添加spring-consumer.xml

14.1spring-consumer.xml

按需修改service名

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

    <dubbo:application name="dubbo-consumer"/>
    <dubbo:registry check="false" address="zookeeper://127.0.0.1:2181"/>
    <dubbo:reference interface="cn.kgc.service.TableToOneService" id="tableToOneService"/>
    <dubbo:reference interface="cn.kgc.service.TableToManyService" id="tableToManyService"/>
</beans>

15再启动类上添加导入资源注解

然后开启Zookeeper服务器,然后开启provider启动类,再开启consumer启动类,最后用postman检测接口是否通畅,根据错误信息修改代码..

整体流程

结束
