FreemarkerConfigurer中的Freemarker WebappTemplateLoader [英] Freemarker WebappTemplateLoader in FreemarkerConfigurer

问题描述

任何人都有一个有关如何在FreemarkerConfigurer中使用Freemarker WebappTemplateLoader的示例吗?

Anyone has an example on how to use Freemarker WebappTemplateLoader in FreemarkerConfigurer?

我将Freemarker与Spring MVC一起使用，并扩展了FreeMarkerConfigurer以添加各种模板加载器，并且我还想添加一个Web应用程序加载器以在Web应用程序上下文中加载模板.但是我不知道如何为其构造函数获取servletcontext参数.

I am using Freemarker with Spring MVC and extending the FreeMarkerConfigurer to add various template loaders and I would also like to add a web app loader to load templates in web app context. But I do not know how to get the servletcontext parameter for its constructor.

public class DesktopFreeMarkerConfigurer extends FreeMarkerConfigurer{  

@Override
protected void postProcessConfiguration(Configuration config){
    [...]
        /* Get templates from the webapp/servlet context */
    WebappTemplateLoader watl = new WebappTemplateLoader(<servletContext>, "default/ftl/");
    [...]
    }
}

我想将webapp/default/ftl添加到模板加载路径，但是由于它是动态的/可配置的，因此无法在xml文件中对其进行硬编码.

I would like to add webapp/default/ftl to template loading path, but as it may be dynamic/configurable, I cannot hardcode it in the xml files.

任何建议将不胜感激.

谢谢 卡门

推荐答案

我假设您正在将DesktopFreeMarkerConfigurer定义为spring bean. 在这种情况下，获取servlet上下文应该很简单. 只需在DesktopFreeMarkerConfigurer类中定义它即可:

I assume you are defining DesktopFreeMarkerConfigurer as a spring bean. In that case, it should be simple to get the servlet context. Just define this in the DesktopFreeMarkerConfigurer class :

@Autowired private ServletContext context;

或者，如果您选择的话，还可以使其实现ServletContextAware:

Or if you choose, you can also make it implements ServletContextAware :

public class DesktopFreeMarkerConfigurer extends FreeMarkerConfigurer implements ServletContextAware {
    private ServletContext servletContext;

    public void setServletContext(ServletContext servletContext) {
        this.servletContext = servletContext;
    }

    @Override
    protected void postProcessConfiguration(Configuration config){
        WebappTemplateLoader watl = new WebappTemplateLoader(this.servletContext, "default/ftl/");
        ...
    }

    ...
}
