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
Velocity IntroductionVelocity is a Java-based template engine. It allows web designer to reference the methods defined in Java code. Web Designer can be programmed concurrently with Java engineers based on the MVC model. In other words, velocity separates Java development from web development.Velocity can also generate web pages, SQL, PostScript, and other output based on the template, or integrate with oth

It is recommended to use the format ${name}, because in the template it is possible to define two variables similar to $name and $names, and if you do not use braces, the engine will not be able to correctly identify the variable $names.For a variable of a complex object type, such as $person, you
