1.一运行，报错说端口8080被占用。原因：项目要用idea来开启tomcat，不要用monitor tomcat里的start打开，后者先打开了tomcat，肯定会占用端口8080啊。2.运行项目，弹出的窗口直接404原因：Project Configurations里面的默认URL一般是http://localhost:8080，如果是默认URL，则Project Configurations里Deployment窗口里Application context里必须为空。PS：我一开始Deploy

突然发现java里面好像全都是类对象方法，然后回过头思考了一下，查到一篇有意思的说明，故记录分享。转载自https://zhidao.baidu.com/question/1114688787541862499.html转载自https://zhidao.baidu.com/usercenter?uid=8fce4069236f25705e79781d&role=ugcBefore：有个类叫人，有个对象叫乌鸡国王后（也就是你），有个方法叫吃饭。1、其中人是对某种高级动物（即某类事物，可以想象

Calendar.getInstance();,获取当前日期add方法，在原日期上增加年/月/日set方法，直接设置年/月/日

结果：

这里的 Integer it = new Integer(i);总是报错，奇怪
