First steps with freemarker with spring mvc

So I have Index action in my HomeController.java class.

I have my freemarker templates in:

/web-inf/ftl/test.ftl

How can I load the template?

I have this in my appname-servlet.xml:

 <bean id="viewResolver"
          class="org.s开发者_C百科pringframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <property name="suffix">
            <value>.ftl</value>
        </property>
    </bean>

    <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="templateLoaderPath" value="/WEB-INF/freemarker/"/>
    </bean>

What should my action code look like for HomeController index action?

I have /web-inf/freemarker/index.ftl

I have used freemarker in a spring-mvc demo webapp (spring 3.0.5). See http://projectnotes.svn.sourceforge.net/viewvc/projectnotes/trunk/ The web controller looks like this, so your index.ftl (which you would put under src/main/webapp/WEB-INF) would be rendered when a request is made to index.html

@Controller
public class IndexController {

    @RequestMapping("/index.html")
    public String index(Map<String, Object> model) {

        // populate the model parameter if you need it in index.ftl   
        return "index";

    }
}

My freemarker context file looks like this

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

From an operational example available on my blog, your controller should look something like this:

@Controller
public class MyController {

    @RequestMapping(value = "/index")
    public String home(Model model) {

            // Populate the model as necessary
            model.addAttribute("MsTime", System.currentTimeMillis());

            return "Home";

    }

}
