Class VelocityConfigurer

java.lang.Object
  org.springframework.ui.velocity.VelocityEngineFactory
      org.springframework.web.servlet.view.velocity.VelocityConfigurer

All Implemented Interfaces:

InitializingBean, ResourceLoaderAware, VelocityConfig

public class VelocityConfigurer

extends VelocityEngineFactory

implements VelocityConfig, InitializingBean, ResourceLoaderAware

JavaBean to configure Velocity for web usage, via the "configLocation" and/or "velocityProperties" and/or "resourceLoaderPath" bean properties. The simplest way to use this class is to specify just a "resourceLoaderPath": You do not need any further configuration then.

<bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath"><value>/WEB-INF/velocity/</value></property>
</bean>

This bean must be included in the application context of any application using Spring's VelocityView for web MVC. It exists purely to configure Velocity. It is not meant to be referenced by application components but just internally by VelocityView. Implements VelocityConfig to be found by VelocityView without depending on the bean name the configurer. Each DispatcherServlet can define its own VelocityConfigurer if desired.

Note that you can also refer to a preconfigured VelocityEngine instance, for example one set up by VelocityEngineFactoryBean, via the "velocityEngine" property. This allows to shared a VelocityEngine for web and email usage, for example.

Method Detail

setVelocityEngine

public void setVelocityEngine(org.apache.velocity.app.VelocityEngine velocityEngine)

Set a preconfigured VelocityEngine to use for the Velocity web config, e.g. a shared one for web and email usage, set up via VelocityEngineFactoryBean. If this is not set, VelocityEngineFactory's properties (inherited by this class) have to be specified.
