SpringBoot项目html加载时间超长，影响使用感受

场景描述：
1.项目在本地测没问题，但是部署到服务器，发现跳页的时候，要等很长的时间，有时甚至有一分钟
2.无论是thymeleaf，还是静态html，都是慢

最后就是使用@RestController，将整个页面返回
将你需要的值，直接拼接到lable的value中

@RestController
@RequestMapping(value = "/data-pipeline")
public class HtmlController {

    @ModelAttribute
    public void setResponseHeader(HttpServletResponse response) {
        response.setHeader("Access-Control-Allow-Origin", "*");
    }

    @RequestMapping(value = "reg")
    public String getRegHtml(String termId){
        return " +
                "      xmlns=\"http://www.w3.org/1999/html\">\n" +
                "\n" +
                "\n" +
                "\n" +
                "    \n" +
                "    \n" +
                "\n" +
                "    \n" +
                "    \n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "
\n" +
                "    \n" +
                "
\n" +
                "
\n" +
                "\n" +
                "
\n" +
                "
\n" +
                "    \n" +
                "
\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n"
                ;
    }
