连接数据库配置驱动

1.1在application中

spring:
  application: 
    name: cloud-export  #eureka.instance.hostname:如果两个都设置，则显示spring.application.name 
  datasource: 
    driver-class-name: oracle.jdbc.OracleDriver # oracle.jdbc.driver.OracleDriver 
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:oracle:thin:@//10.175.94.95:1521/ORCL5
    username: devtest
    password: devtest

如果是mybatis的话，还需要配置

mybatis: 
  mapper-locations: mapper/*.xml,classpath*:mapper/*.xml
  type-aliases-package: com.josion.seckill.pojo
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl   # 配置于控制臺打印日誌(建議上線后移除，僅開發和測試使用)

1.2在pom中

    1.1.12

		3.5.2
    2.0.2

        com.alibaba
        druid
        ${druid.version}
    


	
        
            org.mybatis
            mybatis
            ${mybatis.version}
        
        
            org.mybatis
            mybatis-spring
            ${mybatis-spring.version}
        
        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            ${mybatis-spring-boot-starter.version}
