• web、mybatis、mysql Driver
• 建包
• 该mysql驱动包版本，默认的是8.几版本

            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.45</version>
            <scope>runtime</scope>
        </dependency>

• 测试

@Controller
public class TestController {
    @RequestMapping("/t1")
    public String test(){
        return "test";
    }
}

• 导入静态资源，改页面路径
• 开始写注册功能
