In my application, all freemarker templates are in /templates/ftl/ so during the application deployment I load a class I call one class that extends FreemarkerManager and has a method
Configuration configuration = super.createConfiguration(servletContext);
configuration.setDirectoryForTemplateLoading(new File("/templates/ftl/"));
In this way, when I need to load a template file, I can simply do it like this:
ServletContext servletContext = ServletActionContext.getServletContext();
Configuration configFreemarker = (Configuration) servletContext
.getAttribute("freemarker.Configuration");
Template template = configFreemarker.getTemplate("pathToMyTemplate");
In only one specific situation, I need to get a template that comes from completely different path (not the /templates/ftl/).
How can I in this specific moment declare 2nd directory for template loading without breaking all the existing code that were calling the old path? Can I have 2 different starting point for template loading at the same time?
Thanks
You can use MultipleTemplateLoader
.
import freemarker.cache.*; // template loaders live in this package
...
FileTemplateLoader ftl1 = new FileTemplateLoader(new File("/tmp/templates"));
FileTemplateLoader ftl2 = new FileTemplateLoader(new File("/usr/data/templates"));
ClassTemplateLoader ctl = new ClassTemplateLoader(getClass(), "");
TemplateLoader[] loaders = new TemplateLoader[] { ftl1, ftl2, ctl };
MultiTemplateLoader mtl = new MultiTemplateLoader(loaders);
cfg.setTemplateLoader(mtl);
Source: Freemarker Manual
Another and a more elegant way (in my opinion) of doing this is within the config xml:
<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPaths">
<value>/path1/ , /path2/</value>
</property>
</bean>
