> Key: WW-3765
> URL: https://issues.apache.org/jira/browse/WW-3765
> Project: Struts 2
> Issue Type: Improvement
> Components: Integration
> Affects Versions: 2.3.1
> Environment: Tomcat v7.0
> Reporter: Vijayakannan
> Assignee: Lukasz Lenart
> Priority: Critical
> Labels: freemarker-template-reload-required
> Fix For: 2.3.2
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Struts2 having option to enable the freemarker template caching with
> reloading the template with time delay which helps us to improve the
> performance.
> In our application we are using the strut2 in-built UI freemarker template.
> We need the caching option without reloading the templates after the specific
> time delay.
> Caching option is more powerful if we have an option for enabling\disabling
> the reload
> Proposed Solution
> Struts.xml
> <constant name="struts.freemarker.templatesCache.required" value="true"/>
> FreeMarkerManager.java
> protected boolean templateUpdateRequired;
> @Inject(STRUTS_FREEMARKER_TEMPLATES_RELOAD_REQUIRED)
> public void setTemplateUpdateRequired(String templateUpdateRequired) {
> this.templateUpdateRequired
> ="true".equals(templateUpdateRequired);
> }
> Update createConfiguration(ServletContext servletContext) Method
> configuration.setSetting(Configuration. TEMPLATE_RELOAD_ REQUIRED _KEY,
> templateUpdateRequired);
> Configuration.java
> String TEMPLATE_RELOAD_ REQUIRED _KEY= "template_reload_required";
> TemplateCache.Java
> protected boolean templateUpdateRequired;
> Update getTemplate(TemplateLoader loader, String name, Locale locale, String
> encoding, boolean parse) Method
> ...
