<#macro documentStatVisit>
    <script type="text/javascript">
    (function () {
        var q = [];
        q.push('sid=${Site.id}');
        q.push('cid=${Category.id}');
        q.push('id=${Document.id}');
        var s = document.createElement("script");
        s.src = '${ApiPrefix}api/stat/visit?' + q.join('&');
        (document.getElementsByTagName("head")[0] || document.getElementsByTagName("body")[0]).appendChild(s);
    })();

```

使用   <@documentStatVisit/>

```java
 freemarker.template.Configuration cfg = new freemarker.template.Configuration(
                freemarker.template.Configuration.VERSION_2_3_31);
        cfg.setDefaultEncoding(properties.getDefaultEncoding());
        // 模板加载路径
        MultiTemplateLoader multiTemplateLoader = new MultiTemplateLoader(
                fileTemplateLoaders.stream().toArray(FileTemplateLoader[]::new));
        cfg.setTemplateLoader(multiTemplateLoader);
        cfg.setTemplateExceptionHandler(TemplateExceptionHandler.HTML_DEBUG_HANDLER);

cfg.addAutoImport("jw","/jtag.html");
