Note the springmvc + freemarker garbled code of the configuration

am I full of question marks in Chinese when I integrate Springmvc and freemarker?
this is an error screenshot
Code presentation

@ Bean
public FreeMarkerConfigurer freeMarkerConfigurer () {

FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
configurer.setDefaultEncoding("UTF-8");

configurer.setTemplateLoaderPath("/WEB-INF/views/");
return configurer;

}

@ Bean
public FreeMarkerViewResolver freeMarkerViewResolver () {

FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
resolver.setCache(true);
resolver.setContentType("text/html;charset=UTF-8");
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".ftl");
resolver.setExposeContextBeansAsAttributes(true);
resolver.setOrder(1);
return resolver;

}

this is the content of the page:

<html>
<head>
    <title>FindIt</title>
    <meta http-equiv="Content-type" content="text/html;charset=UTF-8">
    <link href=/public-resources/css/bootstrap/bootstrap.css rel="stylesheet" />
</head>
<body>
<-sharpinclude "header.ftl">
<h1>Hello World! </h1>
<-sharpinclude "footer.ftl">
</body>
</html>

and all my files and projects are in utf-8 format.

4. I"ve tried almost everything I"ve seen online, but I"ve annotated the configuration, and I rarely see similar configurations.
