org.springframework.web.servlet.view.velocity
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
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 of 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 share a VelocityEngine for web and email usage, for example.

This configurer registers the "spring.vm" Velocimacro library for web views (contained in this package and thus in spring.jar), which makes all macros defined in it implicitly available:

 #springBind("person.age")
 age is ${status.value}

Method Summary

void afterPropertiesSet()
          Initialize VelocityEngineFactory's VelocityEngine if not overridden by a preconfigured VelocityEngine.

          Return the VelocityEngine for the current web application context.

protected void postProcessVelocityEngine(org.apache.velocity.app.VelocityEngine velocityEngine)
          Provides a ClasspathResourceLoader in addition to any default or user-defined loader in order to load the spring Velocity macros from the class path.

void setVelocityEngine(org.apache.velocity.app.VelocityEngine velocityEngine)
          Set a preconfigured VelocityEngine to use for the Velocity web config, e.g.
