No 'Access-Control-Allow-Origin' header is present on the requested resource.
報錯：Access to XMLHttpRequest at 'http://localhost:8080/user/get' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.html
最近在寫一個SpringBoot+Mybatis+Ajax的電商秒殺項目遇到bug，
- 這是一個跨域請求的錯誤，程序啓動的時候html頁面是請求本地域名，這種請求能夠正確的達到服務端，而且也有返回，可是Ajax認定他們的域不一樣，是不安全的，會報錯，而且走不到Ajax裏面。
- 處理方式：在SpringBoot中只要Response時刻返回，全部的域便可
- SpringBoot提供了簡單的註解形式@CrossOrigin
