Spring MVC + Webflow 2 + Thymeleaf fragments: can't configure .HTML extension - spring

Question

I have a Spring MVC application with Thymeleaf configured to use fragments (NO tiles!) and all files have .html extension. Everything is working fine.
Now i'm trying to setup Webflow but, when i call my webflow url, i get 404 error as he tries to load a JSP view instead of html (outside flow, everything is fine):
HTTP Status 404 - /app/WEB-INF/views/contest/contest-step1.jsp
I know that put kilometers of line of code isn't good, but honestly i don't know which pieces are interesting and which no.
ThymeleafConfig:
#Configuration
public class ThymeleafConfig {
#Bean
public TemplateResolver templateResolver() {
ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
templateResolver.setPrefix("/WEB-INF/views/");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode("HTML5");
/**
* only on development machine
*/
templateResolver.setCacheable(false);
return templateResolver;
}
#Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
Set<IDialect> dialects = new HashSet<IDialect>();
dialects.add(springSecurityDialect());
templateEngine.setAdditionalDialects(dialects);
templateEngine.setTemplateResolver(templateResolver());
return templateEngine;
}
#Bean
public ThymeleafViewResolver thymeleafViewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
return resolver;
}
#Bean
public SpringSecurityDialect springSecurityDialect(){
SpringSecurityDialect dialect = new SpringSecurityDialect();
return dialect;
}
}
WebAppConfig:
#Configuration
#EnableWebMvc
#ComponentScan("com.myapp")
public class WebAppConfig extends WebMvcConfigurerAdapter {
#Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/login").setViewName("login");
registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
}
#Bean
public UrlBasedViewResolver setupViewResolver() {
UrlBasedViewResolver resolver = new UrlBasedViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
return resolver;
}
// Maps resources path to webapp/resources
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
/**************************************************
*
* Web Flow: wizard contest
*
*/
#Autowired
private WebFlowConfig webFlowConfig;
/**
* Maps request paths to flows in the flowRegistry;
* e.g. a path of /hotels/booking looks for a flow with id "hotels/booking"
*
* Configuring this mapping allows the Dispatcher to map application resource paths
* to flows in a flow registry.
* For example, accessing the resource path /hotels/booking would result in a
* registry query for the flow with id hotels/booking.
* If a flow is found with that id,
* that flow will handle the request. If no flow is found, the next handler mapping in the
* Dispatcher's ordered chain will be queried or a "noHandlerFound" response will be returned.
*/
#Bean
public FlowHandlerMapping flowHandlerMapping() {
FlowHandlerMapping handlerMapping = new FlowHandlerMapping();
handlerMapping.setOrder(-1); //0 ?
handlerMapping.setFlowRegistry(this.webFlowConfig.flowRegistry());
return handlerMapping;
}
#Bean
public FlowHandlerAdapter flowHandlerAdapter() {
FlowHandlerAdapter handlerAdapter = new FlowHandlerAdapter();
handlerAdapter.setFlowExecutor(this.webFlowConfig.flowExecutor());
handlerAdapter.setSaveOutputToFlashScopeOnRedirect(true);
return handlerAdapter;
}
#Bean(name="contest/add") //defined in in WebFlowConfig
public ContestFlowHandler ContestFlowHandler() {
return new ContestFlowHandler();
}
/* TODO
#Bean
public AjaxThymeleafViewResolver tilesViewResolver() {
AjaxThymeleafViewResolver viewResolver = new AjaxThymeleafViewResolver();
viewResolver.setViewClass(FlowAjaxThymeleafTilesView.class);
viewResolver.setTemplateEngine(templateEngine());
return viewResolver;
} */
}
WebFlowConfig:
#Configuration
public class WebFlowConfig extends AbstractFlowConfiguration {
#Autowired
private ThymeleafConfig thymeleafConfig;
//private WebFlowConfig WebAppConfig;
#Bean
public FlowDefinitionRegistry flowRegistry() {
return getFlowDefinitionRegistryBuilder()
.addFlowLocation("/WEB-INF/views/gare/gare-add-flow.xml", "gare/add")
.build();
}
#Bean
public FlowExecutor flowExecutor() {
return getFlowExecutorBuilder(flowRegistry())
.setMaxFlowExecutions(5)
.setMaxFlowExecutionSnapshots(30)
.build();
}
#Bean
public FlowBuilderServices flowBuilderServices() {
return getFlowBuilderServicesBuilder()
.setViewFactoryCreator(mvcViewFactoryCreator())
.build();
}
#Bean
public MvcViewFactoryCreator mvcViewFactoryCreator() {
MvcViewFactoryCreator factoryCreator = new MvcViewFactoryCreator();
factoryCreator.setViewResolvers(Arrays.<ViewResolver>asList(this.thymeleafConfig.thymeleafViewResolver()));
factoryCreator.setUseSpringBeanBinding(true);
return factoryCreator;
}
}
I found a trick that gives me a quick solution, but honestly i would like don't do this, but correctly configure the resolver. The trick is to set the view file in flow xml file:
<view-state id="contest-step1" model="contest" view="/WEB-INF/views/contest/contest-step1.html"></view-state>
thanks

Answer 1

Try the following in flowRegistry method.
return getFlowDefinitionRegistryBuilder(flowBuilderServices())
instead of
return getFlowDefinitionRegistryBuilder()
Hope this helps.

Answer 2

I am not sure but kindly look into the following part of your code
#Bean
public UrlBasedViewResolver setupViewResolver() {
UrlBasedViewResolver resolver = new UrlBasedViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
return resolver;
}
it is pointing to .jsp whatever you call in controller it will append .jsp
Also your controller code is not here url mapping should be like /login.html
I am not much familier with thymeleaf and spring-webflow-2
