How to XML escaping with Apache Velocity?

由 笑着哭i 提交于 2019-12-01 15:50:30
问题 I am generating XML using Apache Velocity. What is the best (most straight-forward) way to XML-escape the output? (I saw there is an escape tool, but could not figure out it's dev state. I also think that XML escaping is something that is very likely supported by Velocity directly.) 回答1: Take a look at event handlers. eventhandler.referenceinsertion.class = org.apache.velocity.app.event.implement.EscapeXmlReference Escape tool is a production ready as well if you need to escape only selective

游戏编程模式-组件模式

　　“允许一个单一的实体跨越多个不同域而不会导致耦合。” 动机 　　在游戏的编程中，我们很容易写出一个超级大而且耦合度很高的类来。比如我们的英雄角色，我会使用各种输入设备来操纵它，会给他添加华丽的技能特效和音效，这就需要我们写很多的代码了，有读取控制器输入的代码，有物理和碰撞的代码，有音效的代码，还有播放动画的代码，最后还要渲染。这些代码我们都掺杂到一个类中，会导致这个类超级的大，这对于维护的人来说简直不能接受，改动代码的代价太大了。到最后我们会发现，我们实现功能的速度远远比不上代码的产生速度。 　　所以我们需要分割代码。就像我们设计一个文字处理器，处理打印部分的代码不应该受到读取、保存文档的代码的任何影响。我们要让物理、AI、渲染、音效这些部分相互独立。比如下面的一段代码： if(collidingWithFloor() && (getRenderState() != INVISIBLE)) { playSound(HIT_FLOOR); } 　　逻辑很清晰，但对于需要修改它的人来说却不简单，他需要了解物理、图像和声效的相关知识，否则任何的更改都可能会引入bug。这无疑对需要维护这段代码的人来说增加了很大的负担。这里的一个解决方案就是分割——我们把功能分成一个一个的域，这样输入输出是一个域，物理引擎和碰撞是一个域、AI是一个域、声效也是一个域。我们按这些域来组织代码

Temporarily disable Meteor testing packages (e.g. Velocity + Mocha) without removing them

Mostly all of the testing lines printed to the console get in my way, especially when I'm just setting up a new project or trying to get this one code bit down that the testing framework isn't too helpful for. Any help is appreciated! I was able to disable Velocity via VELOCITY=0 Before running the server, so basically I ran VELOCITY=0 meteor run Keep in mind that creating a new Meteor project doesn't install Velocity or Mocha by default, so if you have them it's probably because they were manually installed or part of a boilerplate project that you're using. Having said that, I think it's

必备环境： JDK(不低于1.6建议1.7)、 eclipse java EE版 、tomcat(不低于5建议7.0) 为eclipse安装velocity编辑插件： 在Eclipse的Help->Install New Software... 点击“Add加 Veloeclipse，值：http://veloeclipse.googlecode.com/svn/trunk/update/ 注：如果无法安装，在安装插件的界面中把 Group Items by Catagory 前打钩去掉。 创建步骤： 第一步：创建项目 打开eclipse,File -> New -> Other... -> Web -> Dynamic Web Projec 之后按照提示一路next，有两个注意地方： 一是修改代码文件输出路径，默认是build\classes。这个不符合tomcat的要求，需要改成下面这样： 二是勾选 Generate web.xml deployment descriptor 第二步：添加velocity依赖包 velocity相关的包有十多个，我将它们放入网盘方便大家下载，见文章未尾。下载解压后复制全部，选择项目WebContent -> WEB-INF ->lib文件夹，再选择右键菜单粘贴。 项目名右键菜单选择build path -> configure build

Changing Location of Velocity.Log File

由 六月ゝ 毕业季﹏ 提交于 2019-12-01 05:51:48
Seems pretty straight forward. Documentation at http://velocity.apache.org/engine/devel/developer-guide.html#Configuring_Logging says to set the runtime.log property. Here's what I got for all my properties. velocityEngine.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, templatesPath); velocityEngine.setProperty("runtime.log", "/path/to/my/file/velocity.log"); velocityEngine.setProperty("resource.loader", "string"); velocityEngine.setProperty("string.resource.loader.class", "org.apache.velocity.runtime.resource.loader.StringResourceLoader"); velocityEngine.setProperty("string.resource

How to edit a velocimacro without restarting velocity?

My velocity macros are being cached and I don't want them to be... not during development at least. I've set the following properties in my properties file... velocimacro.library.autoreload=true file.resource.loader.cache=false velocity.engine.resource.manager.cache.enabled=false ... but this doesn't seem to have done the trick Using velocity properties, how can I configure velocity to not cache macros? (I'm using velocity 1.6.4) EDIT: I don't think the line... velocity.engine.resource.manager.cache.enabled=false ...is relevant to velocity I have been having the same issue with NVelocity (C#

Velocity Template - regular expressions

由 岁酱吖の 提交于 2019-12-01 02:01:20
I just started using velocity for a new job and I really don't like what I have found already. At this point, i would actually prefer freemarker =X. Anyways, i'm trying to do a regular expression and i saw this little bit (search "regular expression") , but that isn't quite the implementation I am doing. I do not have any access to the java so that option of writing something custom to do this stuff is not there (i'm not even sure if that is possible). This is what i have right now: #set ( $envCheck = "(localhost|staging|qa|cms)\\.site" ) #set ( $envCheck = $envCheck.matches($gatewayURL) ) but
