一、註冊中心

1、在父工程中新建模組

2、配置pom,xml

<dependencies>
        <!--eureka server-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
 

        <!--引入自己定義的api通用包，可以使用payment支付Entity-->
        <dependency>
            <groupId>com.atguigu.springcloud</groupId>
            <artifactId>cloud-api-commons</artifactId>
            <version>${project.version}</version>
        </dependency>
 

        <!--boot web actuator-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--圖形監控-->
        <dependency>
            <
 
groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <!--一般通用配置-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
        </dependency>
    </dependencies>

3、配置application.yml

server:
  port: 7001

eureka:
  instance:
    hostname: localhost #eureka服務端的例項名稱
  client:
    #false表示不向註冊中心註冊自己
    register-with-eureka: false
    #false表示自己端就是註冊中心，我的職責就是維護服務例項，並不需要去檢索服務
    fetch-registry: false
    service-url:
      #設定與Eureka Server互動的地址查詢服務和註冊服務都需要依賴這個地址
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

4、啟動類

@SpringBootApplication
@EnableEurekaServer
public class EurekaMain7001 {
    public static void main(String[] args){
        SpringApplication.run(EurekaMain7001.class,args);
    }
}

二、服務提供者

1、新建模組

2、配置pom.xml

<dependencies>
        <!--引入自己定義的api通用包，可以使用Payment支付Entity-->
        <dependency>
            <!--工程、名字、版本號-->
            <groupId>com.atguigu.springcloud</groupId>
            <artifactId>cloud-api-commons</artifactId>
            <version>${project.version}</version>
        </dependency>
        <!--註冊到中心的依賴-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>
        <!--mysql-connector-java-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

3、配置application.yml

server:
  port: 8001

spring:
  application:
    name: cloud-payment-service
  datasource:
    # 當前資料來源操作型別
    type: com.alibaba.druid.pool.DruidDataSource
    # mysql驅動類
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/db2019?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=GMT%2B8
    username: root
    password: 123456
mybatis:
  mapper-locations: classpath*:mapper/*.xml
  type-aliases-package: com.atguigu.springcloud.entities #entity別名類所在包

#  eureka配置
eureka:
  client:
    #表示是否將自己註冊進EurekaServer預設為true
    register-with-eureka: true
    #是否從EurekaServer抓取已有的註冊資訊，預設為true。單節點無所謂，叢集必須設定為true才能配合ribbon使用負載均衡
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:7001/eureka

4、啟動類

@SpringBootApplication
@EnableEurekaClient
public class PatmentMain8001 {
   public static void main(String[] args){
       SpringApplication.run(PatmentMain8001.class,args);
   }
}
