No 'Access-Control-Allow-Origin' header is present on the requested resource.
报错：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
最近在写一个SpringBoot+Mybatis+Ajax的电商秒杀项目遇到bug，
- 这是一个跨域请求的错误，程序启动的时候html页面是请求本地域名，这种请求能够正确的达到服务端，而且也有返回，可是Ajax认定他们的域不一样，是不安全的，会报错，而且走不到Ajax里面。
- 处理方式：在SpringBoot中只要Response时刻返回，全部的域便可
- SpringBoot提供了简单的注解形式@CrossOrigin
