springboot整合jdbc

• 新建項目
  
• 編寫配置文件

spring:
  datasource:
    username: root
    password: 990801lxq
    url: jdbc:mysql://localhost:3306/mybage?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
    driver-class-name: com.mysql.cj.jdbc.Driver

• 測試是否連接成功

    @Test
    void contextLoads() throws SQLException {
        //查看數據源
        System.out.println(dataSource.getClass());
        //獲取數據庫連接
        Connection connection =dataSource.getConnection();
        System.out.println(connection);
        //關閉
        connection.close();
    }
