快速搭建一个spring cloud 子模板--好记性不如烂笔头

建 application.yml 文件

server:
  # 服务端口号
  port: 7609
spring:
  application:
    # 服务名称 - 服务之间使用名称进行通讯
    name: service-test4
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=UTF-8&&serverTimezone=GMT
    username: root
    password: 123456

启动类：

package com.example.servicetest4;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
//(exclude= {DataSourceAutoConfiguration.class})  加上这注解不用配置数据源，不加需要配置数据源

@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
@EnableEurekaClient
public class ServiceTest4Application {

    public static void main(String[] args) {
        SpringApplication.run(ServiceTest4Application.class, args);
    }

}
测试看到下面两个图：说明简单的一个子项目以及搭建成功
