SpringCloud微服务实战——搭建企业级开发框架（九）（使用Nacos发现、配置和管理微服务） SpringCloud微服务实战——搭建企

????Nacos是一个更易于构建云原生应用的动态服务发现、配置管理和服务管理平台，Nacos 致力于帮助您发现、配置和管理微服务。Nacos 提供了一组简单易用的特性集，帮助您快速实现动态服务发现、服务配置、服务元数据及流量管理。
1、跟之前新建SpringBoot自定义扩展一样，我们在GitEgg_Platform中新建gitegg-platform-cloud子工程，此工程主要用于Spring Cloud相关功能的自定义及扩展。
2、在GitEgg_Platform中的gitegg-platform-bom子工程添加SpringCloud Alibaba的依赖

org.springframework.boot spring-boot-starter-parent 2.3.3.RELEASE 4.0.0com.gitegg.platform gitegg-platform-bom ${project.artifactId} ${gitegg.project.version}pom1.83.8.1UTF-8UTF-8UTF-81.0-SNAPSHOT8.0.179.1-901.jdbc41.1.233.4.03.0.12.2.3.RELEASE com.gitegg.platform gitegg-platform-db ${gitegg.project.version} com.gitegg.platform gitegg-platform-mybatis ${gitegg.project.version} com.gitegg.platform gitegg-platform-swagger ${gitegg.project.version} com.gitegg.platform gitegg-platform-boot ${gitegg.project.version} com.gitegg.platform gitegg-platform-cloud ${gitegg.project.version} mysql mysql-connector-java ${mysql.connector.version} postgresql postgresql ${postgresql.connector.version} com.alibaba druid-spring-boot-starter ${druid.version} com.baomidou mybatis-plus-boot-starter ${mybatis.plus.version} com.github.xiaoymin knife4j-dependencies ${knife4j.version} pom import com.alibaba.cloud spring-cloud-alibaba-dependencies ${spring.cloud.alibaba} pom import

3、在gitegg-platform-cloud工程中引入spring-cloud-starter-alibaba-nacos-discovery

GitEgg-Platform com.gitegg.platform 1.0-SNAPSHOT 4.0.0gitegg-platform-cloud ${project.artifactId} ${project.parent.version}jar com.alibaba.cloud spring-cloud-starter-alibaba-nacos-discovery

【SpringCloud微服务实战——搭建企业级开发框架（九）（使用Nacos发现、配置和管理微服务）】4、GitEgg_Platform工程重新执行install，在GitEgg_Cloud的子工程gitegg-service中引入gitegg-platform-cloud

GitEgg-Cloud com.gitegg.cloud 1.0-SNAPSHOT 4.0.0gitegg-servicepom gitegg-service-base gitegg-service-bigdata gitegg-service-system com.gitegg.platform gitegg-platform-boot com.gitegg.platform gitegg-platform-cloud com.gitegg.platform gitegg-platform-db com.gitegg.platform gitegg-platform-mybatis com.gitegg.platform gitegg-platform-swagger org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-actuator

5、修改application.yml文件，添加nacos配置：

server: port: 8001 spring: application: name: gitegg-service-system cloud: nacos: discovery: server-addr: 127.0.0.1:8848 datasource: type: com.alibaba.druid.pool.DruidDataSource url: jdbc:mysql://127.0.0.1/gitegg_cloud?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf8&allowMultiQueries=true username: root password: root initialSize: 1 minIdle: 3 maxActive: 20 # 配置获取连接等待超时的时间 maxWait: 60000 # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 timeBetweenEvictionRunsMillis: 60000 # 配置一个连接在池中最小生存的时间，单位是毫秒 minEvictableIdleTimeMillis: 30000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false # 打开PSCache，并且指定每个连接上PSCache的大小 poolPreparedStatements: true maxPoolPreparedStatementPerConnectionSize: 20 # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙 filters: config,stat,slf4j # 通过connectProperties属性来打开mergeSql功能；慢SQL记录 connectionProperties: druid.stat.mergeSql=true; druid.stat.slowSqlMillis=5000; # 合并多个DruidDataSource的监控数据 useGlobalDataSourceStat: true mybatis-plus: mapper-locations: classpath*:/com/gitegg/*/*/mapper/*Mapper.xml typeAliasesPackage: com.gitegg.*.*.entity global-config: #主键类型0:"数据库ID自增", 1:"用户输入ID",2:"全局唯一ID (数字类型唯一ID)", 3:"全局唯一ID UUID"; id-type: 2 #字段策略 0:"忽略判断",1:"非 NULL 判断"),2:"非空判断" field-strategy: 2 #驼峰下划线转换 db-column-underline: true #刷新mapper 调试神器 refresh-mapper: true #数据库大写下划线转换 #capital-mode: true #逻辑删除配置 logic-delete-value: 1 logic-not-delete-value: 0 configuration: map-underscore-to-camel-case: true cache-enabled: false

6、修改GitEggSystemApplication.java添加注解@EnableDiscoveryClient,然后运行GitEggSystemApplication：

package com.gitegg.service.system; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.context.annotation.ComponentScan; /** * gitegg-system 启动类 */ @EnableDiscoveryClient @ComponentScan(basePackages = "com.gitegg") @MapperScan("com.gitegg.*.*.mapper") @SpringBootApplication public class GitEggSystemApplication {public static void main(String[] args) { SpringApplication.run(GitEggSystemApplication.class,args); }}

7、在浏览器中打开nacos的地址，点击左侧菜单的服务列表，可以查看到服务已经注册到nacos
