Spring thymeleaf implementation

Question

Hi can someone refer me or teach me on how do I implement thymeleaf in spring framework? I have a dynamic web project but all the tutorials I have seen uses maven. I am trying to work this for almost a week.

I have these beans:

<bean id="templateResolver" class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
  <property name="prefix" value="/WEB-INF/Views/" />
  <property name="suffix" value=".html" />
  <property name="templateMode" value="HTML5" />
  <constructor-arg ref="servletContext"/>
</bean>

<bean id="templateEngine"
      class="org.thymeleaf.spring4.SpringTemplateEngine">
  <property name="templateResolver" ref="templateResolver" />
</bean>

I get this error:
