By reading some velocity documents, you can write down what you see as a simple and unsystematic note, which enhances your memory.Dynamic Language features:
A Dynamic Language requires an interpreter, which is generally on the server.MVC
Model: Indicates the status of the system and application, which is generally a class or other data structure. Can change the system statusActionsAndMethod. TypicalJavabean. The original intention is to separate data
The Java code called in velocity is invalid or cannot be debugged.
The standard way velocity calls Java code is as follows:
$! {Classname. staticMethod ()} or $! {Objectname. instanceMethod ()}
For example:
$! {Salehelper. isWltUser ($ info. getCateID (), $ info. getUserID ())}
This code belongs to the type of the instance method called by the object. There are two points to note:
1. The syntax format

Since a large number of friends did not go to the site, they could not fully express what I meant in the PPT, so I wrote this blog for some text instructions. If you have any questions
Velocity CheckingForNull, checkingfornull
Q: I want to check for null, something like this:
#if ($car.fuel == null)
A: There are several approaches. Select the one most suitable depending on what you really want to do.
Approach 1:Use the fact that null is evaluated as a false conditional. (cf. http://velocity.apache.org/engine/devel/user-guide.html#Conditionals)
#if( ! $car.fuel )
Note:The conditional will also pass if the result of $ car. fuel is t

This is the Intercept. The application of Kalman filter to the fusion of gyroscope and accelerometer is an explanation of Kalman filter, according to the interpretation of the article and some matrix theory (matrix multiplication, covariance matrix, etc.) with the knowledge of the above 5 equations, you can understand the entire derivation process, the final programming can be achieved
The first way:
In SPRINGMVC projects, there are times when you need to use multiple view formats, such as Jsp,velocity and Freemarker, to map to different view files through different request path configuration rules. Below I provide a way of thinking, through the view template file suffix name to deal with. For example:
@RequestMapping (value = "/hello")Public String jsptest (httpservletrequest request, Modelmap map) {return "demo.jsp";}The JSP's vie
