Handling FreeMaker template with Ktor Kotlin

I'm very new to Kotlin (and Java), as well as Ktor and FreeMaker , trying to make an app combining all of them, but looks I'm doing something wrong related to the FreeMaker templates manipulating. My app structure is: template.ftl : <#macro mainLayout title="Welcome"> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>${title} | Kweet</title> </head> <body> HI </body> </html> </#macro> index.ftl : <#import "template.ftl" as layout /> imported title: ${title} <@layout.mainLayout title="Welcome"> <div class="posts"> <h3 class="content-subhead

freemarker与JSP在同一页面中使用

先申明, 这个实践非常不好, 只有在某些时间确实需要这玩意的时候才使用. 原理很简单, 使用HTML的注释 因为JSP的注释是<%--内容--%>, freemarker的注释是<#--内容-->, 而JSP/freemarker的标签在中时, 是可以被正常解析的, 而不支持的标签则会原样输出.  ${test} 这里的test在JSP中将会输出JSP, 而freemarker中将会输出freemarker, 但是, 上面JSP中会留下  在freemarker中会留下 <!-- <%@ page contentType="text/html;charset=UTF-8" language="java"

How can I embed one DropWizard (with freemarker) View in another one?

阅读更多关于 How can I embed one DropWizard (with freemarker) View in another one?

I am using DropWizard and Freemarker to build up a view which displays different types of forms based on results from a webservice. I have created the forms as views - each with their own ftl. So, in my resource, I discover which form I need, then load the main.ftl, passing the form view as a parameter (see below). This doesn't work. Can anyone see where we're going wrong? Or is there a completely different way to chain views together using DropWizard and freemarker? @GET public Form getForm() { FormView view = new FormView(service.getForm()); return new MainView(view); } public class FormView

How to access a Spring application property in a Freemarker template?

I have Java webapp that uses Spring 3.1, with Freemarker templates for rendering the view. I want to conditionally display a link in the view, based on the true/false value of a particular application property. I have the following app property defined in src/main/resources/application.properties : showLink=true If I were using a regular JSP with Spring MVC, I could use SpEL to conditionally display the link based on the value of showLink : <c:if test="${configuration['showLink']}"> <a href="...">some link</a> </c:if> How do I do this in a Freemarker template? I tried doing something like this

How to check the existense of a freemarker template before include it

Sometimes I have to use the following snippet : <#include 'some.ftl' /> Does freemarker have a directive that return the existense of some.ftl ? Like <#include_if_exists 'some.ftl' > Or can I implement such a directive by myself? OK. Resolved by user-directive [@include template='some.ftl' /] WARN if template not found... import java.io.FileNotFoundException; import java.io.IOException; import java.util.Map; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import freemarker.core.Environment; import freemarker.template.Template; import freemarker.template.TemplateDirectiveBody; import

使用Freesql简单地实现多条件查询

阅读更多关于使用Freesql简单地实现多条件查询

在实际应用中我们经常会遇到多条件查询的情景，以往的解决方案是在java中对各个参数值进行非空之类的判断，再进行sql及参数的拼凑。其实还有更简单的解决方法的--用Freemarker。Freemarker可以轻松的使用if之类的进行判断，当if条件时再使用指定的sql片段。而Freesql就是在Freemarker的基础上，配合java中sql的参数设置进行的简单封装，可以简单方便的编写动态的sql。如何使用Freesql 本文介绍如何在JFinal中使用Freesql。Freesql的jar包可以从 http://git.oschina.net/jse7en/Freesql/ 中下载。Freesql默认提供对JFinal的支持，在JFinal中可以简单的使用JFinal。初始化Freesql 在JFinalConfig中添加Freesql插件 public class ProjectConfig extends JFinalConfig { //... @Override public void configPlugin(Plugins me) { //Freesql默认使用web根目录下的freesql作为模板存放根目录 FreesqlPlugin freesql = new FreesqlPlugin(); /

问题 I'm trying to get freemarker working under Google App Engine. I've gotten simple ftl template files working when requested directly however I'd like to have index.ftl work if available otherwise index.html -- or vice versa. If I request /index.html , it renders fine as HTML. If I request /index.ftl , it renders fine as a FreeMarker template. Variables are expanded. If, however, I request '/' it gives the following 404 message: Problem accessing /index.html/index.ftl. I have the following in
