velocity

问题 I'd like to assign a random value to a variable in a velocity template. However, #set ($random = $math.getRandom()) returns: java.util.Random@5706937e. How to obtain this value or assign a random value to a variable in a different way from within a velocity template? 回答1: #set ($random = $math.getRandom()) use velocity 1.7 from this link enter link description here and in vm file use #set($mathTool = $serviceLocator.findService("org.apache.velocity.tools.generic.MathTool")) //range: 1 - 20

问题 I use velocity to create a string writer, then merge that into a template. The template #includes html to make a simple table, yet only the raw HTML shows up in the email... it does not get rendered. Email is being sent from Google server to outlook client. Can anyone tell me How can I get rendered HTML into an email message created with Velocity? Thanks! 回答1: You have to set a Content-type: text/html header. Appart from that, you have to be aware that all the different email clients may

问题 I am in need of the basic understanding of how velocity changing works? i.e. how CCSprite is able to jump at particular height when some velocity is set? Let me give you an example on which I am working currently. I am preparing a demo like flappy bird, in which I wanted my bird to land on vertical pipes. So, it is like, my birdy jumps from the pipe to another pipe :smile:. Check the gif I place here: https://www.dropbox.com/s/n46vak6qy5wu4x4/jumpyBall_15_jul_152.gif?dl=0 I am using Sprite

问题 Is there a way to configure Velocity to use something other than toString() to convert an object to a string in a template? For example, suppose I'm using a simple date class with a format() method, and I use the same format every time. If all of my velocity code looks like this: $someDate.format('M-D-yyyy') is there some configuration I could add that would let me just say $someDate instead? (Assuming I'm not in a position to just edit the date class and give it an appropriate toString()). I

问题 So I want to access all the documents that are tagged using 2 tags instead of one. For example I want all photoshop tutorial documents.If I searched with the tag tutorial I would get other software tutorials too and if I use the tag photoshop i get all documents and not just the tutorials. I should be able to provide 2 tags and get documents which are tagged with both these tags. Right now this is what I did, #set ($list = $wiki.tag.getDocuments($tag)) #set ($list2 = $list.getDocuments($tag2)

问题 I have an array of objects $arr and an object has a property named as jsonData which contains json data in a string, how to parse that string to actual JSON object and retrieve lets say value for key name ? I tried this: #foreach ($obj in $arr) #set ($jsonData = "#evaluate(${obj.jsonData})") $jsonData.get("name") ## <-- not working #end 回答1: If anyone using velocity in AWS API Gateway ends up here, you can use AWS' $util.parseJson() to covert a string to JSON. Make sure you note if your

问题 I am trying to access a String array which i have created in my Java class. The string array is stored in a Map with the name 'notSelected' using the same key. I also have a single String object called 'testString' stored in the same Map which i can easily access and display using: $testString However how do i go about accessing the String array object (notSelected) from the Map inside the velocity template object? I have tried: $notSelected.get(0) $notSelected[0] $notSelected.[0] $
