注册中心（EureKa配置）

Maven配置：基本上的错误为版本号错误，版本错误见前面博客

• pomx.ml

<parent>
    <artifactId>OnlineShop</artifactId>
    <groupId>com.li</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    </dependency>
</dependencies>

启动类

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

}

application.yml

#    端口号
server:
  port: 8001
spring:
  application:
    name: eureka-provider
eureka:
  instance:
    hostname: localhost # Eureka访问地址
  client:
    register-with-eureka: false # 禁止自己注册自己
    fetch-registry: false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

本地文件系统

Maven配置

• pomx.ml

<parent>
    <artifactId>OnlineShop</artifactId>
    <groupId>com.li</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>os_configserve</artifactId>
<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-server</artifactId>
        <version>2.0.2.RELEASE</version>
    </dependency>
</dependencies>

启动类

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

application.yml

server:
  port: 8002
spring:
  application:
    name: config-provider
  profiles:
    active: native # 配置文件的获取方式本地读取
  cloud:
    config:
      server:
        native:
          search-locations: classpath:/shared  # 本地配置文件的存放位置

配置读取文件的路径，在resources文件夹下建/shared文件夹，并且创建order-dev.yml配置文件，和后面的服务互相对应。order-dev.yml的内容如下

server:
  port: 8010 # order-dev的端口号

服务提供

pom.xml

<parent>
    <artifactId>OnlineShop</artifactId>
    <groupId>com.li</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>order</artifactId>
<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>

        <version>2.0.2.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-config</artifactId>
        <version>2.0.2.RELEASE</version>
    </dependency>
</dependencies>

启动类

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

测试类

@RestController
@RequestMapping("/order")
public class OrderController {

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

    @GetMapping("/index")
    public String index(){
        return "order的端口是"+this.port;
    }
}

bootstrap.yml配置文件

spring:
  application:
    name: order #之前在配置文件中的文件名字order-dev.yml
  profiles:
    active: dev
  cloud:
    config:
      uri: http://localhost:8002 # 配置configserver的端口号
      fail-fast: true

依次启动注册中心、本地文件系统、服务

浏览器访问 localhost:8001 如下可以看到注册的服务

访问测试地址如下
