I use Velocity. Implemented a 'Template Service' to expose velocity engine
to pages and components. Using Velocity's datasource resource loader to
load templates from database. Here's an outline:
public interface TemplateService {
public String getMergedTemplate(String templateName, Map<String, Object>
context);
}
In AppModule
public VelocityEngine buildVelocityEngine(
@Symbol(SystemPreferenceConstants.APACHE_VELOCITY_CONFIG_CATAEGORY) String
preferenceCategory,
@Inject SystemPreferenceService preferenceService,
@Inject SqlSessionFactory sessionFactory, Logger logger) {
if (velocityEngine == null)
{
velocityEngine = initVelocityEngine(preferenceCategory, preferenceService,
sessionFactory, logger);
}
return velocityEngine;
}
And TemplateServiceImpl.java
@InjectService("VelocityEngine")
VelocityEngine velocityEngine;
@Override
public String getMergedTemplate(String templateName, Map<String, Object>
context) {
StringWriter stringWriter = new StringWriter();
VelocityContext systemProvidedContext = new VelocityContext(context,
systemContext);
systemProvidedContext.put(ipAddressTemplateToken, getRemoteAddress(
requestGlobal.getHTTPServletRequest()));
if(velocityEngine.resourceExists(templateName))
{
velocityEngine.mergeTemplate(templateName, templateEncoding,
systemProvidedContext, stringWriter);
}
logger.debug(stringWriter.toString());
return stringWriter.toString();
}
GetRemote address above just takes care of substituting the right host name
etc. in the templates.
Best Regards,
Sanket
