【踩坑】JDBC 报错 Loading class `com.mysql.jdbc.Driver' ...

前言

运行JDBC代码后，报错：Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

原因

  • mysql 8.0在注册驱动的时候应该是com.mysql.cj.jdbc.Driver，而mysql 5.0在注册驱动的时候才是com.mysql.jdbc.Driver

问题解决

  • 将注册驱动改为com.mysql.jdbc.Driver
1
Class.forName("com.mysql.jdbc.Driver");
  • 亦或者无需注册

完成
