使用Spring 4 + Tiles模板+ Freemarker进行utf8编码

Question

我尝试将Spring 4（4.3.0。），tile 3（3.0.7）和FreeMarker 2（2.3.25-incubating）集成到我拥有的模板定义文件中：

<definition name="base-definition" template="/WEB-INF/views/tiles/layouts/layout.ftl" templateType="freemarker">
    <put-attribute name="title" value="" />
    <put-attribute name="body" value="" />
</definition>

<!-- Home Page -->
<definition name="home" extends="base-definition">
   <put-attribute name="title" value="Welcome" />
   <put-attribute name="body" value="/WEB-INF/views/jsp/home.jsp" />
</definition>

针对home.jsp：

<%@ page errorPage="error.jsp" contentType="text/html; charset=utf-8"%>
....

layouts.ftl：

<!DOCTYPE html>
<html lang="sk">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
....
<title><@tiles.insertAttribute name="title" /></title>
</head>
<body>
<section id="site-content">
<@tiles.insertAttribute name="body" />
</section>
ľščťžýáíéúä
</body>
</html>

我有带有registerAttributeRenderers函数的CustomTilesContainerFactory（扩展了BasicTilesContainerFactory）：

@Override
protected void registerAttributeRenderers(final BasicRendererFactory rendererFactory,
        final ApplicationContext applicationContext, final TilesContainer container,
        final AttributeEvaluatorFactory attributeEvaluatorFactory) {
    super.registerAttributeRenderers(rendererFactory, applicationContext, container, attributeEvaluatorFactory);

    FreemarkerRenderer freemarkerRenderer = FreemarkerRendererBuilder.createInstance()
            .setApplicationContext(applicationContext).setParameter("TemplatePath", "/")
            .setParameter("NoCache", "true").setParameter("ContentType", "text/html")
            .setParameter("template_update_delay", "0").setParameter("default_encoding", "UTF-8")
            .setParameter("number_format", "0.##########")
            .setParameter(SharedVariableLoaderFreemarkerServlet.CUSTOM_SHARED_VARIABLE_FACTORIES_INIT_PARAM,
                    "tiles," + TilesSharedVariableFactory.class.getName())
            .build();
    rendererFactory.registerRenderer(FREEMARKER_RENDERER_NAME, freemarkerRenderer);
}

我有带有createContainerFactory函数的CustomTilesInitializer（扩展了DefaultTilesInitializer）：

@Override
protected AbstractTilesContainerFactory createContainerFactory(ApplicationContext context) {
    return new CustomTilesContainerFactory();
}

但在网络浏览器中，HTTP响应标头可以：

text/html; charset=utf-8

但是当我检查网页的属性时（鼠标右键单击），请编码为“ windows-1252”，这是一个问题，为什么没有utf-8？ 当然，特殊字符也有问题，在layouts.ftl中存在“ľščťžýáíéúä”，而在网络浏览器中是??????ýáíéúä。

谢谢！

Answer 1

解：

@RequestMapping(value = { "/index" }, method = RequestMethod.GET)
public String homePage(ModelMap model, HttpServletResponse response) {
        response.setContentType("text/html;charset=UTF-8");
        return "home";
}

但是，这不是一个很好的解决方案:-(是否需要在ALL请求映射函数中设置内容类型？:-(
