velocity shows

The project structure is as shown in the screenshot: 1, first, the introduction of velocity programming required jar package, build all kinds of files. Under the required JAR package: 2. Configure the Web. xml file Hellohandler.java specific code is as follows: public class Hellohandler extends velocityviewservlet{private static final long serialversionuid = 1L; Private Velocityengine Velo; @Override public void Init () throws servletexce

There are several ways to determine if it is null: 1. #if (! $foo) determine that $foo is empty and that non-null is #if ($foo) 2. Use #ifnull () or #ifnotnull () #ifnull ($foo) To use this feature, you must include the following in the Velocity.properties file: userdirective = org.apache.velocity.tools.generic.directive.Ifnull userdirective = Org.apache.velocity.tools.generic.directive.Ifnotnull 3. Use the null tool to determine #if ($null. IsNull ($foo)) Note that this is especially useful,

parsing and including corresponding resource files# Parse ("me. VM"), which shares the corresponding context with the main file # Stop: Used to stop parsing and return results. It is mainly used for debugging.6. Velocity # macro is quite powerful.# Macro, similar to macro definition, is used to customize the corresponding tag.A macro is defined as follows, which is used to output the list in the table.# Macro (tablerows $ color $ somelist)# Foreach (

Velocity. Exception. parseerrorexception: encountered " Was expecting one: "("..."##"..."\\\\"..."\\"..."*#"..."*#"..."{"..."}"... After checking for more than an hour, I found that there is a # if not used # End closed in the VM file. The problem is solved.

Velocity foreach usage, velocityforeach# Set ($ result =$ {list })# Set ($ I = 0)# Foreach ($ onlineData in $ {onlineDataList })$ Result. get ($ I)# Set ($ I = $ I + 1)# Foreach ($ hour in [0 .. 23])# End # Foreach ($ online in $ onlineData) # End # End Note: onlineDataList is a list defined in the background. It accesses multiple onlineData and onlineData is also a list.

1. Path Problem When Using velocityengine. gettemplate (filepath) (The resource does not exist) Note: The relative path must be used to set the template location. The path is relative to the "file. Resource. loader. Path" attribute of velocityengine. You can set this attribute as follows. Velocityengine VE = new velocityengine (); Ve. setproperty ("file. Resource. loader. Path", "E: // resource // Java // tpsno02 // res // template // test "); Ve. INIT (); 2.

The standard notation for velocity calls Java code is this $! {Classname.staticmethod ()} or $! {Objectname.instancemethod ()} Like what: $! {Salehelper.iswltuser ($info. Getcateid (), $info. GetUserID ())} This code, which belongs to the type of the object invocation instance method, needs to be noted for two places: 1, the syntax format must be correct, otherwise call not to the back-end Java method, and not to debug to the 2, the parameter ty

Recently, in the project, you need to add and subtract operations in the VM page, such as #set ($balance =$!{ sumamont}+$! {surcharge}-$! {Depositamount})Always error, print on the page is 100+50-120 In the tangle for a long time after finally resolved, recorded here, one is to remind themselves, the second is for everyone to meet this error not like me, tangled too long. The symbols on the page in velocity automatically call the ToString metho

There are several workarounds for Velocity's $ vs. jquery $ conflict: 1. Use jquery instead of $. such as: Jquery.ajax (); Cons: Not suitable for expansion, once replaced with a third-party library, it is troublesome 2, use Jquery.noconflict. such as: var j = jquery.noconflict (); J.ajax (); Cons: When using jquery's related plugins, it will invalidate the plugin. 3. The conflict method in wrap jquery. If $.ajax () conflicts in velocity, it is red

Learn the things to write here, forget to come back at any time to check, good memory than bad blog, haha, good nonsense not to say, this article mainly introduces the integration of SPRINGMVC and MyBatis Note: SPRINGMVC version 3.1.2. MyBatis version 3.2.2 Database is Oracle First look at the configuration of Spring.xml Very simple, just configure the @service support and database connection resource files, of course you can also add some other need to initialize the resource files; 2.

Problem Description: In the context of using the Velocity template engine, when using jquery, such as: $.fullcalendar.gcalfeed (' http://www.google.com/calendar/feeds/sfzc1% 40realintelligence.com/public/basic ') where $ conflicts with velocity variables. Solution: Define a velocity variable: #set ($jquery = "$.") Then: ${jquery}fullcalendar.gcalfeed

The configuration of a rigid mobile robot is usually described in 6 variables: his three-dimensional Cartesian coordinate system, and the relative external coordinate system of three Euler angles (RPY roll, pitch, yaw), so in the plane environment generally with three variables can be described, called posture.So in general, the posture information of a robot is a two-dimensional planar coordinate (x, y) of a robot and its azimuth Θ\theta, which is represented by this vector:⎛⎝⎜xyθ⎞⎠⎟\begin{pmat
