Eureka 模块

来实现服务治理

服务治理就是提供了微服务架构中各微服务实例的快速上线或下线且保持各服务能正常通信的能力的方案总称

建立eureka模型

导入依赖

xml 复制代码

        </dependency>
    </dependencies>
</project>

编写配置文件

启动类

服务注册

在provider-dept导入依赖

xml 复制代码

<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-eureka -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>

添加注解

先启动eureka，再启动provider

结果

完善监控信息

结果

集群环境

新建eureka-7002和eureka-7003模型，代码和7001一样,apolication.yml改下端口号

修改host

java 复制代码

127.0.0.1       eureka7001.com
127.0.0.1       eureka7002.com
127.0.0.1       eureka7003.com

再修改application.yml

修改provider-dept的application.yml

启动7001，7002，7003，provider

结果
