痛定思痛。 2022-02-05 03:19 313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

  1. spring:
  2.   profiles:
  3.     active: 
  4.     - dev
  5. ---
  6. server:
  7.   port: 8001
  8. spring:
  9.   profiles: dev  
  10.   application:
  11.     name: springcloud-config-dept-client
  12.   datasource:
  13.     type: com.alibaba.druid.pool.DruidDataSource            
  14.     driver-class-name: org.gjt.mm.mysql.Driver              
  15.     url: jdbc:mysql://192.168.106.130:3305/clouddb03             
  16.     username: root
  17.     password: 123456
  18.     dbcp2:
  19.       min-idle: 5                                           
  20.       initial-size: 5                                       
  21.       max-total: 5                                          
  22.       max-wait-millis: 200  
  23. mybatis:
  24.   config-location: classpath:mybatis/mybatis.cfg.xml        
  25.   type-aliases-package: com.atguigu.springcloud.entities    
  26.   mapper-locations:
  27.   - classpath:mybatis/mapper/**/*.xml                       
  28. eureka:
  29.   client:
  30.     service-url: 
  31.       defaultZone: http://eureka7001.com:7001/eureka/
  32.   instance:
  33.     instance-id: dept-8001.com  
  34.     prefer-ip-address: true
  35. info:
  36.   app.name: atguigu-microservicecloud-springcloudconfig01
  37.   company.name: www.atguigu.com
  38.   build.artifactId: ${project.artifactId}
  39.   build.version: ${project.version}
  40. ---
  41. server:
  42.   port: 8001
  43. spring:
  44.   profiles: test  
  45.   application:
  46.     name: springcloud-config-dept-client
  47.   datasource:
  48.     type: com.alibaba.druid.pool.DruidDataSource            
  49.     driver-class-name: org.gjt.mm.mysql.Driver              
  50.     url: jdbc:mysql://192.168.106.130:3305/clouddb02             
  51.     username: root
  52.     password: 123456
  53.     dbcp2:
  54.       min-idle: 5                                           
  55.       initial-size: 5                                       
  56.       max-total: 5                                          
  57.       max-wait-millis: 200  
  58. mybatis:
  59.   config-location: classpath:mybatis/mybatis.cfg.xml        
  60.   type-aliases-package: com.atguigu.springcloud.entities    
  61.   mapper-locations:
  62.   - classpath:mybatis/mapper/**/*.xml                       
  63. eureka:
  64.   client:
  65.     service-url: 
  66.       defaultZone: http://eureka7001.com:7001/eureka/
  67.   instance:
  68.     instance-id: dept-8001.com  
  69.     prefer-ip-address: true
  70. info:
  71.   app.name: atguigu-microservicecloud-springcloudconfig01
  72.   company.name: www.atguigu.com
  73.   build.artifactId: ${project.artifactId}
  74.   build.version: ${project.version}
  75. #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

  1. spring:
  2.   profiles:
  3.     active: 
  4.     - dev
  5. ---
  6. server:
  7.   port: 7001
  8. spring:
  9.   profiles: dev  
  10.   application:
  11.     name: springcloud-config-eureka-client
  12. eureka:
  13.   instance:
  14.     hostname: eureka7001.com
  15.   client:
  16.     register-with-eureka: false
  17.     fetch-register: false
  18.     service-url: 
  19.       defaultZone: http://eureka7001.com:7001/eureka/
  20. ---
  21. server:
  22.   port: 7001
  23. spring:
  24.   profiles: test  
  25.   application:
  26.     name: springcloud-config-eureka-client
  27. eureka:
  28.   instance:
  29.     hostname: eureka7001.com
  30.   client:
  31.     register-with-eureka: false
  32.     fetch-register: false
  33.     service-url: 
  34.       defaultZone: http://eureka7001.com:7001/eureka/
  35. #必须保存为UTF-8格式

3、推送到GitLab上
在这里插入图片描述
二、Config版的eureka服务端
1、新建microservicecloud-config-eureka-client-7001工程
2、引入依赖

  1. <dependencies>
  2.     <!-- 热部署插件 -->
  3.     <dependency>
  4.         <groupId>org.springframework</groupId>
  5.         <artifactId>springloaded</artifactId>
  6.     </dependency>
  7.     <dependency>
  8.         <groupId>org.springframework.boot</groupId>
  9.         <artifactId>spring-boot-devtools</artifactId>
  10.     </dependency>
  11.     <!-- eureka服务注册中心 -->
  12.     <dependency>
  13.         <groupId>org.springframework.cloud</groupId>
  14.         <artifactId>spring-cloud-starter-eureka-server</artifactId>
  15.     </dependency>
  16.     <dependency>
  17.         <groupId>org.springframework.cloud</groupId>
  18.         <artifactId>spring-cloud-starter-config</artifactId>
  19.     </dependency>
  20. </dependencies>

3、application.yml配置

  1. spring:
  2.   application:
  3.     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。

  1. spring:
  2.   cloud:
  3.     config:
  4.       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
  5.       profile: dev
  6.       label: master
  7.       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

  1. @SpringBootApplication
  2. @EnableEurekaServer
  3. public class SpringCloudConfigEurekaClient7001_App {
  4.     public static void main(String[] args) {
  5.         SpringApplication.run(SpringCloudConfigEurekaClient7001_App.class,args);
  6.     }
  7. }

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

  1. <dependencies>
  2.     <dependency>
  3.         <groupId>com.atguigu.springcloud</groupId>
  4.         <artifactId>microservicecloud-api</artifactId>

  46.         <artifactId>spring-boot-devtools</artifactId>
  47.     </dependency>
  48.     <!-- 将微服务provider侧注册进eureka -->
  49.     <dependency>
  50.         <groupId>org.springframework.cloud</groupId>
  51.         <artifactId>spring-cloud-starter-eureka</artifactId>

  53.     <dependency>
  54.         <groupId>org.springframework.cloud</groupId>
  55.         <artifactId>spring-cloud-starter-config</artifactId>
  56.     </dependency>
  57.     <!-- hystrix-dashboard相关： actuator监控 -->
  58.     <dependency>
  59.         <groupId>org.springframework.boot</groupId>
  60.         <artifactId>spring-boot-starter-actuator</artifactId>
  61.     </dependency>
  62. </dependencies>

3、application.yml配置

  1. spring:
  2.   application:
  3.     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。

  1. spring:
  2.   cloud:
  3.     config:
  4.       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
  5.       profile: dev
  6.       label: master
  7.       uri: http://config3344.com:3344    #SpringCloudConfig获取的服务地址

5、启动服务。
