Known Direct Subclasses |
Factory that configures a FreeMarker Configuration. Can be used standalone, but typically you will either use FreeMarkerConfigurationFactoryBean for preparing a Configuration as bean reference, or FreeMarkerConfigurer for web views.
The optional "configLocation" property sets the location of a FreeMarker
properties file, within the current application. FreeMarker properties can be
overridden via "freemarkerSettings". All of these properties will be set by
calling FreeMarker's Configuration.setSettings()
method and are
subject to constraints set by FreeMarker.
The "freemarkerVariables" property can be used to specify a Map of
shared variables that will be applied to the Configuration via the
setAllSharedVariables()
method. Like setSettings()
,
these entries are subject to FreeMarker constraints.
The simplest way to use this class is to specify a "templateLoaderPath"; FreeMarker does not need any further configuration then.
Note: Spring's FreeMarker support requires FreeMarker 2.3 or higher.

Set the location of the FreeMarker config file. Alternatively, you can specify all setting locally.
Set the default encoding for the FreeMarker configuration. If not specified, FreeMarker will use the platform file encoding.
Used for template rendering unless there is an explicit encoding specified for the rendering process (for example, on Spring's FreeMarkerView).
setEncoding(String)
Set properties that contain well-known FreeMarker keys which will be
passed to FreeMarker's Configuration.setSettings
method.
Set a Map that contains well-known FreeMarker objects which will be passed
to FreeMarker's Configuration.setAllSharedVariables()
method.
Set a List of The TemplateLoader TemplateLoaders specified here will be
registered after the default template loaders that this factory
registers (such as loaders for specified "templateLoaderPaths" or any
loaders registered in TemplateLoader
s that will be used to search
for templates. For example, one or more custom loaders such as database
loaders can be configured.
postProcessTemplateLoaders(List
).
Set a List of The TemplateLoader TemplateLoaders specified here will be
registered before the default template loaders that this factory
registers (such as loaders for specified "templateLoaderPaths" or any
loaders registered in TemplateLoader
s that will be used to search
for templates. For example, one or more custom loaders such as database
loaders could be configured and injected here.
postProcessTemplateLoaders(List
).
Set whether to prefer file system access for template loading. File system access enables hot detection of template changes.
If this is enabled, FreeMarkerConfigurationFactory will try to resolve the specified "templateLoaderPath" as file system resource (which will work for expanded class path resources and ServletContext resources too).
Default is "true". Turn this off to always load via SpringTemplateLoader (i.e. as stream, without hot detection of template changes), which might be necessary if some of your templates reside in an expanded classes directory while others reside in jar files.
Set the Spring ResourceLoader to use for loading FreeMarker template files. The default is DefaultResourceLoader. Will get overridden by the ApplicationContext if running in a context.
Set the Freemarker template loader path via a Spring resource location. See the "templateLoaderPaths" property for details on path handling.
Set multiple Freemarker template loader paths via Spring resource locations.
When populated via a String, standard URLs like "file:" and "classpath:" pseudo URLs are supported, as understood by ResourceEditor. Allows for relative paths when running in an ApplicationContext.
Will define a path for the default FreeMarker template loader.
If a specified resource cannot be resolved to a java.io.File
,
a generic SpringTemplateLoader will be used, without modification detection.
To enforce the use of SpringTemplateLoader, i.e. to not resolve a path as file system resource in any case, turn off the "preferFileSystemAccess" flag. See the latter's javadoc for details.
If you wish to specify your own list of TemplateLoaders, do not set this
property and instead use setTemplateLoaders(List templateLoaders)
