痛定思痛。 2022-02-05 03:19 252阅读 0赞

一、配置文件托管到GitLab  
1、在文件夹springcloud-config下新建配置文件springcloud-config-dept-client.yml

spring:
      profiles:
        active: 
        - dev
    ---
    server:
      port: 8001
    spring:
      profiles: dev  
      application:
        name: springcloud-config-dept-client
      datasource:
        type: com.alibaba.druid.pool.DruidDataSource            
        driver-class-name: org.gjt.mm.mysql.Driver              
        url: jdbc:mysql://192.168.106.130:3305/clouddb03             
        username: root
        password: 123456
        dbcp2:
          min-idle: 5                                           
          initial-size: 5                                       
          max-total: 5                                          
          max-wait-millis: 200  
    mybatis:
      config-location: classpath:mybatis/mybatis.cfg.xml        
      type-aliases-package: com.atguigu.springcloud.entities    
      mapper-locations:
      - classpath:mybatis/mapper/**/*.xml                       
    eureka:
      client:
        service-url: 
          defaultZone: http://eureka7001.com:7001/eureka/
      instance:
        instance-id: dept-8001.com  
        prefer-ip-address: true
    info:
      app.name: atguigu-microservicecloud-springcloudconfig01
      company.name: www.atguigu.com
      build.artifactId: ${project.artifactId}
      build.version: ${project.version}
    ---
    server:
      port: 8001
    spring:
      profiles: test  
      application:
        name: springcloud-config-dept-client
      datasource:
        type: com.alibaba.druid.pool.DruidDataSource            
        driver-class-name: org.gjt.mm.mysql.Driver              
        url: jdbc:mysql://192.168.106.130:3305/clouddb02             
        username: root
        password: 123456
        dbcp2:
          min-idle: 5                                           
          initial-size: 5                                       
          max-total: 5                                          
          max-wait-millis: 200  
    mybatis:
      config-location: classpath:mybatis/mybatis.cfg.xml        
      type-aliases-package: com.atguigu.springcloud.entities    
      mapper-locations:
      - classpath:mybatis/mapper/**/*.xml                       
    eureka:
      client:
        service-url: 
          defaultZone: http://eureka7001.com:7001/eureka/
      instance:
        instance-id: dept-8001.com  
        prefer-ip-address: true
    info:
      app.name: atguigu-microservicecloud-springcloudconfig01
      company.name: www.atguigu.com
      build.artifactId: ${project.artifactId}
      build.version: ${project.version}
    #必须保存为UTF-8格式

2、在文件夹springcloud-config下新建配置文件springcloud-config-eureka-client.yml

spring:
      profiles:
        active: 
        - dev
    ---
    server:
      port: 7001
    spring:
      profiles: dev  
      application:
        name: springcloud-config-eureka-client
    eureka:
      instance:
        hostname: eureka7001.com
      client:
        register-with-eureka: false
        fetch-register: false
        service-url: 
          defaultZone: http://eureka7001.com:7001/eureka/
    ---
    server:
      port: 7001
    spring:
      profiles: test  
      application:
        name: springcloud-config-eureka-client
    eureka:
      instance:
        hostname: eureka7001.com
      client:
        register-with-eureka: false
        fetch-register: false
        service-url: 
          defaultZone: http://eureka7001.com:7001/eureka/
    #必须保存为UTF-8格式

3、推送到GitLab上

二、Config版的eureka服务端  
1、新建microservicecloud-config-eureka-client-7001工程  
2、引入依赖

<dependencies>
        
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>springloaded</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>
        
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
    </dependencies>

3、application.yml配置

spring:
      application:
        name: springcloud-config-eureka-client

4、bootstrap.yml配置。主要负责从从外部源加载配置属性并解析配置。

spring:
      cloud:
        config:
          name: springcloud-config-eureka-client     #需要从github上读取的资源名称，注意没有yml后缀名
          profile: dev
          label: master
          uri: http://config3344.com:3344  #该微服务启动后先去找服务配置中心3344，通过SpringCloudConfig获取GitLab地址

5、在主启动类添加@EnableEurekaServer注解

@SpringBootApplication
    @EnableEurekaServer
    public class SpringCloudConfigEurekaClient7001_App {
        public static void main(String[] args) {
            SpringApplication.run(SpringCloudConfigEurekaClient7001_App.class,args);
        }
    }

6、先启动配置中心服务端，再启动config-eureka-client工程。

二、Config版的部门提供者  
1、参考microservicecloud-provider-dept-8001新建microservicecloud-config-dept-client-8001工程  
2、引入依赖

<dependencies>
        <dependency>
            <groupId>com.atguigu.springcloud</groupId>
            <artifactId>microservicecloud-api</artifactId>
            <version>${project.version}</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jetty</artifactId>

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
        
        <dependency>

            <artifactId>spring-boot-devtools</artifactId>
        </dependency>
        
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
        
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>

3、application.yml配置

spring:
      application:
        name: springcloud-config-dept-client

4、bootstrap.yml配置。主要负责从从外部源加载配置属性并解析配置。

spring:
      cloud:
        config:
          name: springcloud-config-dept-client    #需要从github上读取的资源名称，注意没有yml后缀名
          profile: dev
          label: master
          uri: http://config3344.com:3344    #SpringCloudConfig获取的服务地址

5、启动服务。
