Nvelocity configuration details

Before velocityengine initialization, you can use extendedproperties to configure the nvelocity runtime environment parameters. After the velocityengine Init (extendedproperties) is executed, nvelocity combines custom configurations and default configurations. Nvelocity defines the default configuration item name in nvelocity. runtime. runtimeconstants and defines the values of all default configuration items in the embedded resource file nvelocity. runtime. defaults. nvelocity. properties. Some common configurations are listed below:

Template code:

Input. Encoding = ISO-8859-1 // template input Encoding
Output. Encoding = ISO-8859-1 // template output Encoding

# Foreach Configuration

Directive. foreach. Counter. Name = velocitycount // counter name
Directive. foreach. Counter. Initial. value = 1 // counter Initial Value
Directive. foreach. maxloops =-1 // The maximum number of cycles.-1 indicates that directive. foreach. iterator. Name = velocityhasnex by default. // iterator name

# Set Configuration

Directive. Set. null. Allowed = false // whether a null value can be set

# Include configuration

Directive. Include. Output. errormsg. Start = <! -- Include error: // The start string is prompted for the error message.
Directive. Include. Output. errormsg. End = see error log --> // the error message prompts the end string.

# Parse Configuration

Directive. parse. Max. Depth = 10 // resolution depth

Template loader Configuration

 

Resource. loader = file // template loader type. The default value is file. You can define multiple

File. Resource. loader. Description = velocity file resource loader // loader description
File. Resource. loader. Class = nvelocity. runtime. Resource. loader. fileresourceloader // loader Class Name
File. Resource. loader. Path =. // template path
File. Resource. loader. cache = false // whether to enable template Cache
File. Resource. loader. modificationcheckinterval = 2 // check the template Change Interval

Macro Configuration

velocimacro. permissions. allow. inline = true // whether it can be defined in the row
velocimacro. permissions. allow. inline. to. replace. global = false // whether the global definition can be replaced by intra-row definition
velocimacro. permissions. allow. inline. local. scope = false // whether the intra-row definition is only used for local use

Velocimacro. Context. localscope = false // whether the macro is used only for local
Velocimacro. Max. Depth = 20 // resolution depth

Velocimacro. Arguments. Strict = false // whether the strict mode is enabled for macro parameters

Resource Manager Configuration

Resource. Manager. Class = nvelocity. runtime. Resource. resourcemanagerimpl // manager class name
Resource. Manager. cache. Class = nvelocity. runtime. Resource. resourcecacheimpl // cache Class Name

Parser pool Configuration

Parser. Pool. Class = nvelocity. runtime. parserpoolimpl // resolution pool class name
Parser. Pool. size = 40 // initial size

#Evaluate Configuration

Directive. Evaluate. Context. Class = nvelocity. velocitycontext // name of the Question class

Configurable introspector configurations

Runtime. introspector. uberspect = nvelocity. util. introspection. uberspectimpl // default introspector Class Name In nvelocity, multiple configurations can be defined, such as the resource loader. Note that the incoming implementation class name must be:Class fullname;Assembly nameFormat, for example, a custom resource loader easynet. MVC. assemblyresourceloader,ProgramThe Set Name Is easynet. MVC, which should be defined as follows:

Code
Velocityengine Velocity =   New Velocityengine ();

Extendedproperties props= NewExtendedproperties ();

//Define a resource Loader
Props. addproperty (runtimeconstants. resource_loader,"Easynet. MVC. assemblyresourceloader; easynet. MVC");

//Initialization
Velocity. INIT (props );
