一、注册中心
1、在父工程中新建模块
2、配置pom.xml
<dependencies> <!--eureka server--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> <!--引入自己定义的api通用包,可以使用payment支付Entity--> <dependency> <groupId>com.atguigu.springcloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>${project.version}</version> </dependency> <!--boot web actuator--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--图形监控--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <!--一般通用配置--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> </dependency> </dependencies>
3、配置application.yml
server:
port: 7001
eureka:
instance:
hostname: localhost #eureka服务端的实例名称
client:
#false表示不向注册中心注册自己
register-with-eureka: false
#false表示自己端就是注册中心,我的职责就是维护服务实例,并不需要去检索服务
fetch-registry: false
service-url:
#设置与Eureka Server交互的地址查询服务和注册服务都需要依赖这个地址
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
4、启动类
@SpringBootApplication @EnableEurekaServer public class EurekaMain7001 { public static void main(String[] args){ SpringApplication.run(EurekaMain7001.class,args); } }
二、服务提供者
1、新建模块
2、配置pom.xml
<dependencies> <!--引入自己定义的api通用包,可以使用Payment支付Entity--> <dependency> <!--工程、名字、版本号--> <groupId>com.atguigu.springcloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>${project.version}</version> </dependency> <!--注册到中心的依赖--> <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: # 当前数据源操作类型 type: com.alibaba.druid.pool.DruidDataSource # mysql驱动类 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别名类所在包 # eureka配置 eureka: client: #表示是否将自己注册进EurekaServer默认为true register-with-eureka: true #是否从EurekaServer抓取已有的注册信息,默认为true。单节点无所谓,集群必须设置为true才能配合ribbon使用负载均衡 fetch-registry: true service-url: defaultZone: http://localhost:7001/eureka
4、启动类
@SpringBootApplication @EnableEurekaClient public class PatmentMain8001 { public static void main(String[] args){ SpringApplication.run(PatmentMain8001.class,args); } }
