Integrating Spring WebFlow with Thymeleaf - spring-mvc

Question

I am developing SpringMVC application using Thymeleaf Templates fragment. I want to add simple flow. This is my project structure and configuration:
My spring-servlet.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

</bean>
<import resource="webflow.xml" />
<!-- Spring WebFlow -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"

<property name="prefix" value="/flows" />
<property name="suffix" value=".html" />
<property name="order" value="2"></property>
</bean>
</beans>
webflow.xml file:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:webflow="http://www.springframework.org/schema/webflow-config"
xsi:schemaLocation="http://www.springframework.org/schema/beans

<webflow:flow-executor id="flowExecutor"
flow-registry="flowRegistry" />
<webflow:flow-builder-services id="flowBuilderServices"
view-factory-creator="mvcViewFactoryCreator" />
<bean id="mvcViewFactoryCreator"
class="org.springframework.webflow.mvc.builder.MvcViewFactoryCreator">
<property name="viewResolvers" ref="thymeleafViewResolver" />
</bean>
</beans>
and add-quiz-flow.xml:
<flow xmlns="http://www.springframework.org/schema/webflow"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/webflow
http://www.springframework.org/schema/webflow/spring-webflow-2.4.xsd"
start-state="quizName">
<view-state id="quizName" view="flows/adding-quiz/quizName" >
<transition on="addQuestion" to="quizQuestion" />
</view-state>
<view-state id="quizQuestion" view="flows/adding-quiz/quizQuestion">
<transition on="nextQuestion" to="quizQuestion" />
<transition on="finish" to="finish" />
</view-state>
<end-state id="finish"/> <!-- Jakies "zapisano do bazy, czy cos -->
And now:
Property viewResolvers in mvcViewFactoryCreator bean is set to viewResolver(so it is pointing at InternalResourceViewResolver).My flow works fine, but it is doesn't include thymleaf template fragment,There is only simple pages, without header and footer.
As I read in thymeleaf docs : Integrating Thymeleaf and WebFlow
I am supposed to add thymeleafViewResolver and change property in mvcViewFactoryCreator from
<property name="viewResolvers" ref="viewResolver" />
to
<property name="viewResolvers" ref="thymeleafViewResolver" />
In this configuration whole applcation works fine (templates are included), but when trying to start flow, typing:http://localhost:8070/addQuiz?quizName I'm, getting folowing error:
`org.thymeleaf.exceptions.TemplateInputException: Error resolving template "/adding-quiz/quizName", template might not exist or might not be accessible by any of the configured Template Resolvers`
Do you have any idea, where I'm going wrong?

Answer 1

Ok, it seems that I've handled the problem. There were few mistakes:
Firstly, I've changed
<view-state id="quizName" view="/adding-quiz/quizName">
to
<view-state id="quizName" view="/flows/adding-quiz/quizName">
After that I found a bug in html file. Now, configuration looks working properly.
