I am trying to create a very simple integration of FreeMarker and Spring. However, when I run my example, I get an exception:
GRAVE: Servlet.service() for servlet MyServlet threw exception

I don't know what's wrong with my configuration:

Web Configuration
@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "com.jverstry")
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver getViewResolver() {
FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
resolver.setCache(true);
resolver.setPrefix("WEB-INF/pages/");
resolver.setSuffix(".ftl");
return resolver;
}
@Bean
public FreeMarkerConfigurer getFreemarkerConfig() {
FreeMarkerConfigurer result = new FreeMarkerConfigurer();
result.setTemplateLoaderPath("WEB-INF/pages/");
return result;
}
}
Controller
@Controller
public class MyController {
@RequestMapping(value = "/")
public String home(@ModelAttribute("model") ModelMap model) {
model.addAttribute("MsTime", System.currentTimeMillis());
return "Home";
}
}
P.S.: Of course, there is a Home.ftl file in WEB-INF/pages/.
After searching a lot, not setting a prefix solved the issue:
@Bean
public ViewResolver getViewResolver() {
FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
resolver.setCache(false);
// resolver.setPrefix("");
resolver.setSuffix(".ftl");
return resolver;
}
configuration for the freemaker (found in the spring reference documentation) http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/htmlsingle/#view-velocity
<!-- freemarker config -->
<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath" value="/WEB-INF/freemarker/"/>
</bean>
<!--
View resolvers can also be configured with ResourceBundles or XML files. If you need
different view resolving based on Locale, you have to use the resource bundle resolver.
-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
<property name="cache" value="true"/>
<property name="prefix" value=""/>
<property name="suffix" value=".ftl"/>
</bean>
and java config version would be :
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;
import org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver;
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver() {
FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
resolver.setCache(true);
resolver.setPrefix("");
resolver.setSuffix(".ftl");
return resolver;
}
@Bean
public FreeMarkerConfigurer freemarkerConfig() {
FreeMarkerConfigurer result = new FreeMarkerConfigurer();
result.setTemplateLoaderPath("/WEB-INF/pages/");
return result;
}
}
