Velocity, literally translated as: speed, speed, and speed, used in web development, there may not be many people who have used it, most of them basically know and are using struts, in the end, how does velocity and Struts (taglib and tiles) contact? In terms of technology, velocity is more advanced than struts (taglib and tiles).
Many people have seen or learned velocity, the name literal translation: speed, rate, rapid, used in web development, the use of people may not be many, most of the basic know and in the use of struts, in the end velocity and struts how to contact, how to see velocity? Let's try it out, to understand the concept of velocity

The design idea of the velocity Technology Survey template engine was first proposed by webmacro and applied to a famous search engine www.altavista.com. Later, this idea was gradually adopted by the Apache development team and proposed as a sub-project. This is the current velocity.
What is velocity?Velocity is a Java
we want to extend some common methods, you can write some common methods Xxxtool tool class, and then register in Toolbox.Viii. Internationalization1 current locale: $locale Although Velocity-tools 2.0 provided the Messagetool, but I have not tried to succeed, only with the use of the struts2 itself to deal with the label. The basename of internationalized resource files must be defined first in STRUTS21 Then in the Classpath directory, put two file

The implementation of this method provided by velocity comes from MVC. Web designer designs a template that uses HTML tags and template language (velocity template language), while the velocity template engine plays a controlling role, java developers only need to provide the relevant data as a map or other variables to this template
Velocity is a Java-based template engine. It allows web page designers to refer to methods defined in Java code. Web designers can work in parallel with Java programmers to develop MVC-mode Web sites, which means that Web page designers can focus only on creating well-designed sites, and programmers can focus only on writing top-tier code. Velocity separates Java code from Web pages, making Web sites more m
First, the basic grammar1, "#" used to identify velocity script statements, including #set, #if, #else, #end, #foreach, #end, #iinclude, #parse, #macro等;Such as:#if ($info. IMGs)#else#end
2, "$" to identify an object (or understanding as a variable);such as: $i, $msg, $TagUtil. Options (...) Wait
3, "{}" used to identify the velocity variable clearly;For example, in the page, the page has a $someonename,
Note:
Velocityjs in npm contains the name from the original velocity. changed js to velocityjs and felt require ("velocity. js ") is not easy to understand, so the name is changed. Versions later than 0.3.0 are all updated under velocityjs.

The use of velocity as a page display layer is common, as a template form, may not use more, at least now I have only a few times, the following is a previous article found, for example, the velocity as a template for use, or very practical.
Typically, the velocity template's file suffix is ". VM". We're going to create a hellovelocity.vm template file, which is
Using velocity as a page display layer is common, as a template form appears, may not be used more, at least now I have only used a few times, the following is also found in an article, for example, the use of velocity as a template, or very practical.
Typically, the file suffix of the velocity template is ". VM". Here we create a HELLOVELOCITY.VM template file,
1. First download velocity. http://velocity.apache.org/
2. Download tomcat 6.0 (windows Service installer) and install it on D: \ Program Files \ Apache Software Foundation \
3. Create a WebSite vtl in MyEclipse. The default website folder is WebRoot.
Add the following testVtlclass to WebRoot:Package com. cl. vtl;

, and the corresponding view is called as required to display the data returned by the model and is primarily responsible for scheduling work.What is the benefit of this division of responsibilities, it simplifies the software development process of all the relevant personnel work, so that the different parts of the modification will not usually affect the work of other parts, for example, I modified the background of some programs, the algorithm does not affect the foreground page display, fore
This is an entry-level velocity article. Although it is very simple, it can indeed explain the working principle of velocity and is worth reading.

Velocity:a template engine or A rule engine or Both?
Most of the developers must is familiar with Velocity as a great open source template engine and I don ' t do I need to s Ay much about its uses and features as a template engine. This paper compiles it features as a rule engine.
I have been working with Java for the past 6 years and recently, I got a opportunity to design and develop a entitlement Application.

Summary of velocity knowledge points
1. Variables
(1) definition of variables:
# Set ($ name = "hello"): variables in velocity are weak.
When the # set command is used, the literal strings enclosed in double quotation marks are parsed and re-interpreted as follows:
# Set ($ directoryroot = "www ")
# Set ($ templatename = "index. VM ")
# Set ($ template = "$ directoryroot/$ templatename ")
$ Template
). Transfer control between the view and the model, and call the corresponding view to display the data returned by the model, mainly responsible for the dispatch work.What is the benefit of this division of responsibility? It simplifies the software development process of all the people involved in the work, so that different parts of the changes usually will not affect the other parts of the work, for example, I modified some of the background program algorithm, does not affect the front page

When spring MVC integrates velocity, it is necessary to introduce related packages. The packages to be imported are as follows:
Then, it is very simple configuration, then here, modify the content of the springMvc-servlet.xml, the content is modified as follows
Then create the velocity. properties file in the WEB-INF folder, the content is very simple, just a few words
