一、生产者配置

服务层service引入pom 及配置文件

<?xml version="1.0" encoding="UTF-8"?>
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>com.atguigu.gmall</groupId>
        <artifactId>gmall-parent</artifactId>

    <name>gmall-user-service</name>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>com.atguigu.gmall</groupId>
            <artifactId>gmall-service-util</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

        <dependency>

            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

服务层配置文件application.properties

# 服务端口
server.port=8070

# jdbc
spring.datasource.username=root
spring.datasource.password=199610w
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/gmall?allowMultiQueries=true&useUnicode=true&characterEncoding=utf8&useSSL=false

# mybtais配置
mybatis.mapper-locations=classpath:mapper/*Mapper.xml
mybatis.configuration.map-underscore-to-camel-case=true

# 日志级别
logging.level.root=debug


# dubbo中的服务名称
dubbo.application.name=user-service
# dubbo的通讯协议名称
dubbo.protocol.name=dubbo
#用dubbo协议在20880端口暴露服务,默认是20880
dubbo.protocol.port=20880
# zookeeper注册中心的地址
dubbo.registry.address=127.0.0.1:2181
# zookeeper的通讯协议的名称
dubbo.registry.protocol=zookeeper
# dubbo的服务的扫描路径
dubbo.base-package=com.atguigu.gmall

向zookeeper注册服务

二、消费者配置

消费层引入pom

<?xml version="1.0" encoding="UTF-8"?>
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>com.atguigu.gmall</groupId>
        <artifactId>gmall-parent</artifactId>
        <version>1.0-SNAPSHOT</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <groupId>com.atguigu.gmall</groupId>
    <artifactId>gmall-user-web</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>gmall-user-web</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>com.atguigu.gmall</groupId>
            <artifactId>gmall-api</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

        <dependency>
            <groupId>com.atguigu.gmall</groupId>
            <artifactId>gmall-web-util</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

消费层配置文件

# 服务端口
server.port=8071

# dubbo的配置
dubbo.application.name=user-web
# dubbo的通讯协议名称
dubbo.protocol.name=dubbo
# zookeeper注册中心的地址
dubbo.registry.address=127.0.0.1:2181
# zookeeper的通讯协议的名称
dubbo.registry.protocol=zookeeper
# dubbo的服务的扫描路径
dubbo.base-package=com.atguigu.gmall
# 设置超时时间,防止测试的bug
spring.dubbo.consumer.timeout=600000
# 设置是否检查服务存在
dubbo.consumer.check=false

消费者消费服务

三、zookeeper注册中心信息

 以上可以看到，生产者与消费者启动成功后，它们都会在相应的服务下面创建一个临时节点，关闭服务，临时节点被删除。

userService为启动的服务，包括生产者与消费者

catalogService为还启动了但又关闭的服务，只有dubbo一些基本信息的节点
