08-Config学习

Config：Git环境搭建

自己话理解：把配置放在码云上，然后去引用，这样就不用一个一个改配置了，就在码云上改就行~

1.gitee 创建一个仓库

2.git clone

3.写一个application.yml

4.提交

git add .

git commit -m “信息”

git push origin master

spring:
  profiles:
    active: dev
---
spring:
  profiles: dev
  application:
    name: springcloud-config-dev
---
spring:
  profiles: test
  application:
    name: springcloud-config-test

---

服务端连接Git

第一步、new module 加依赖

• springcloud-config-server-3344

  <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-server</artifactId>
        <version>2.1.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

第二步、application.yml

server:
  port: 3344
spring:
  application:
    name: springcloud-config-server
    # 连接远程仓库
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/tianqinglong/springcloud-study.git # https 不是git

第三步、主启动类

@SpringBootApplication
@EnableConfigServer
public class Config_Server_3344 {
    public static void main(String[] args) {
        SpringApplication.run(Config_Server_3344.class,args);
    }
}

测试访问 http://localhost:3344/application-dev.yml 或

http://localhost:3344/master/application-dev.yml

客户端连接服务端访问远程

第一步，编写config-client.yml git push到码云

spring:
  profiles:
    active: dev

---
server:
  port: 8201
#spring配置
spring:
  profiles: dev
  application:
    name: springcloud-provider-dept
# eureka的配置 服务注册到哪里
eureka:
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka/,http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/


---
server:
  port: 8202
#spring配置
spring:
  profiles: test
  application:
    name: springcloud-provider-dept

# eureka的配置 服务注册到哪里
eureka:
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka/,http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/

第二步、new module 加依赖

• springcloud-config-client-3355

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-config</artifactId>
        <version>2.1.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

第三步、编写bootstrap.yml application.yml

bootstrap.yml

# 系统级别的配置 application是用户级别的配置
spring:
  cloud:
    config:
      uri: http://localhost:3344
      name: config-client #从git上读取的资源名称，不用后缀
      profile: test
      label: master

application.yml

spring:
  application:
    name: springcloud-config-client-3355

第四步、controller

package com.tian.springcloud.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ConfigController {

    @Value("${spring.application.name}")
    private String applicationName;

    @Value("${eureka.client.service-url.defaultZone}")
    private String eurekaServer;

    @Value("${server.port}")
    private String port;

    @RequestMapping("/config")
    public String getConfig(){
        return "applicationName"+applicationName+
                "eurekaServer"+eurekaServer+
                "port"+port;

    }
}

第五步、主启动类

package com.tian.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ConfigClient_3355 {
    public static void main(String[] args) {
        SpringApplication.run(ConfigClient_3355.class,args);
    }
}

测试访问 http://localhost:8202/config

远程配置实战测试

编写一个config-eureka.yml git push

spring:
  profiles:
    active: dev
---
server:
  port: 7001
#spring配置
spring:
  profiles: dev
  application:
    name: springcloud-config-eureka
#Eureka配置
eureka:
  instance:
    hostname: eureka7001.com #Eureka服务器的实例名称
  client:
    register-with-eureka: false #表示是否向eureka注册中心注册自己
    fetch-registry: false # 如果为false，则表示自己为注册中心
    service-url: #监控页面~
      # 单机  defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
      # 集群  （关联）：
      defaultZone: http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/
---
server:
  port: 7001
#spring配置
spring:
  profiles: test
  application:
    name: springcloud-config-eureka
#Eureka配置
eureka:
  instance:
    hostname: eureka7001.com #Eureka服务器的实例名称
  client:
    register-with-eureka: false #表示是否向eureka注册中心注册自己
    fetch-registry: false # 如果为false，则表示自己为注册中心
    service-url: #监控页面~
      # 单机  defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
      # 集群  （关联）：
      defaultZone: http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/

第一步、new module 依赖

• springcloud-config-eureka-7001
• 代码其实和springcloud-eureka-7001 一样

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>

        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>

第二步、application.yml bootstrap.yml

application.yml

spring:
  application:
    name: springcloud-config-eureka

bootstrap.yml

# 系统级别的配置 application是用户级别的配置
spring:
  cloud:
    config:
      uri: http://localhost:3344
      name: config-eureka #从git上读取的资源名称，不用后缀
      profile: dev
      label: master

第三步、启动访问localhost:7001

再体验

编写一个config-dept.yml git push

spring:
  profiles:
    active: dev
---

server:
  port: 8001

---

server:
  port: 8001

# mybatis配置
mybatis:
  type-aliases-package: com.tian.springcloud.pojo
  mapper-locations: classpath:mybatis/mapper/*.xml
  config-location: classpath:mybatis/mybatis-config.xml
