html + Vue.js + ajax ======》 Java接口

错误提示：

Access to XMLHttpRequest at 'HTTP/HTTPS接口' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

解决方法：

接口中设置： response.setHeader("Access-Control-Allow-Origin", "*"); # 建议吧 * 换成域名
