Of course, looking for cases of the big people generally want to go directly to a case on the line, not a lot of time to read a lot of text, so not long-winded. One of course first to download velocity required jar bag, everywhere there are downloads of course I'm going to the official download, after all, the official things are generally more formal To say the Apache official, think of just start out to work in the basic daily in the official Apac

(Do not use this template, the latest version of spring boot is not supported.) Use Freemarker bar: http://blog.csdn.net/clementad/article/details/51942629) In a few simple steps, use the velocity template to generate text in spring boot: 1. Introduction of Dependency 2. Create templates directory in Resources 3. Create a. VM template file Welcome.vm: 4, use the template, test cases: @Autowired velocityengine velocityengine;

There are two ways to integrate struts2 with velocity 1, mainly to struts2. Struts2 built-in support for velocity, as long as the Issue: When accessing VM files directly, the source code of the VM is output. How to prohibit direct access to *.VM type files. Benefit: You can use similar struts tags. I always feel that this is a strange use. 2, with velocity as t

1. How to get the WiFi object and operate the WiFi device, you need to get Context.getsystemservice (Context.wifi_service) to get the Wifimanager object, and use this object to manage WiFi devices. Addnetwork (wificonfiguration config) Adds a config description of the WiFi network, by default, this

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 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

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
