I have simple doGet method in Spring:
#Override
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
HttpSession session = req.getSession(true);
List<Category> categories = categoriesService.getCategories();
req.setAttribute("categories", categories);
if (!resp.isCommitted()) {
req.getRequestDispatcher("thymeleaf_views/categories.html").forward(req, resp);
}
}
I can get html page. But its all content is not resolved((
<body>
<div>
<h2>Categories</h2>
<ul id="menu" style="list-style-type:none">
<li th:each="category: ${categories}" th:text="${category.name}"></li>
</ul>
</div>
</body>
When I try to load the page - it loads tags as it is - does not substitute tags with its content(( What can be the reason?
You have to set a TemplateResolver. E. g. like the way below:
#Configuration
public class ThymeleafConfig {
#Bean
public ServletContextTemplateResolver templateResolver() {
ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
resolver.setPrefix("/WEB-INF/jsp/");
resolver.setSuffix(".html");
resolver.setTemplateMode("HTML5");
return resolver;
}
#Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver(templateResolver());
return engine;
}
#Bean
public ThymeleafViewResolver thymeleafViewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
return resolver;
}
}

I'm trying to implement the OpenSessionInView pattern (antipattern) with Spring 5. I configured via Java (not xml) the OpenSessionInView in my WebMvcConfigurer, and watching the logs it seems that is already running. But when I try to load a lazy collection it says the known "Could not write JSON: failed to lazily initialize a collection of role:..."
The crazy stuff is that I see in my logs:
DEBUG [http-nio-8080-exec-7] (OpenSessionInViewInterceptor.java:128) - Opening Hibernate Session in OpenSessionInViewInterceptor

DEBUG [http-nio-8080-exec-7] (OpenSessionInViewInterceptor.java:153) - Closing Hibernate Session in OpenSessionInViewInterceptor
So, it seems that the session is opened as it should, is not closed when the exception is thrown. But my EntityManager is not using that session... Am I correct? How can I achieve that?
Thanks!

Project structure - IMAGE
I have tried to move templates to resources but still nothing. Please help. I have no more ideas how to fix this ... It worked earlier and then stopped.
Thymeleaf Resolver will look under templates/login/ for a login.html page. Based on your project structure and configuration, you rightly have a login folder inside template but you don't have a login.html inside the directory which is why the reason for the error.
Either create a login.html inside the login folder or use the index.html page which is already there. In your spring controller you should return the appropriate page.
For example,
Assuming that you need to show the login page your controller method should return,
return "login/login" // to display login.html under `templates/login`
or
return "login/index" // to display index.html under `templates/login`
This is my AppInitializer:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = "com.project.app")
public class AppInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer implements
WebApplicationInitializer {
#Override
public void onStartup(ServletContext container) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(AppConfig.class);
ctx.setServletContext(container);
ServletRegistration.Dynamic servlet = container.addServlet(
"dispatcher", new DispatcherServlet(ctx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
}
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { AppConfig.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
And this is my AppConfig:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = "com.acfcm.app")
#Import({ SecurityConfig.class })
public class AppConfig extends WebMvcConfigurerAdapter {
#Bean
public ViewResolver viewResolverForClasses() {
ResourceBundleViewResolver viewResolver = new ResourceBundleViewResolver();
viewResolver.setOrder(1);
viewResolver.setBasename("views");
return viewResolver;
}
#Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setOrder(2);
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
#Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
}
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations(
"/resources/");
}
}
What I want is how to change the AppConfig to put .jsp in differents foldes into the project because right now only can save it in /WEB-INF/views/ and there is a lot of .jsp!! I want to have two more folders to see my project like:
WEB-INF/views/moduleOne/
WEB-INF/views/moduleTwo/
...
Thanks!
I think your code is all fine; it will look for your JSPs starting in /WEB-INF/views/
Most people do like you say and break up JSP views under folders like /admin, /common, etc.
The way you do this is to specify the subfolder in the controller. For example, in your controller, you could return:
#RequestMapping(value = "/admin/index.htm", method = RequestMethod.GET)
public ModelAndView index(HttpServletRequest request,
HttpServletResponse response)
{
Map<String, Object> myModel = new HashMap<String, Object>();
myModel.put("someValues", new ArrayList());
ModelAndView mv = new ModelAndView("admin/index","model", myModel);
return mv;
}
Doing it like the above, you can put your JSP under
/WEB-INF/views/admin/index.jsp
Of course, your mappings (/admin) doesn't have to match the directory structure (/WEB-INF/views/admin) but we chose to make both match, to make it faster to find the code (if controller mapping matches the dir structure).
The important thing to remember is that whatever you put in that ModelAndView first param, Spring will prepend and append the values you defined in your code:
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
So, if you return ModelAndview("/pierre/was/here/something"), Spring will try to find the JSP at location: "/WEB-INF/views/pierre/was/here/something.jsp"
The common practice is to have the configuration as yours, and in the request handler controller methods, use the view names as moduleOne/view1, moduleTwo/view2 etc.
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.

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
Try the following in flowRegistry method.
return getFlowDefinitionRegistryBuilder(flowBuilderServices())
instead of
return getFlowDefinitionRegistryBuilder()
Hope this helps.
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
I'm trying to add a custom DateFormatter to my spring/thymeleaf application, with the help of the following documentation :
http://www.thymeleaf.org/doc/html/Thymeleaf-Spring3.html#conversions-utility-object
The problem is that I don't use xml configuration for my beans definitions, but a WebConfig.java class with the following implementation :
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = {"com.myapp.web.controller","net.atos.wfs.wts.adminportal.web.domain"})
public class WebConfig extends WebMvcConfigurerAdapter {
private static final Logger LOG = LoggerFactory.getLogger(WebConfig.class);
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
#Override
public void addInterceptors(InterceptorRegistry registry) {
LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
localeChangeInterceptor.setParamName("lang");
registry.addInterceptor(localeChangeInterceptor);
}
#Bean
public LocaleResolver localeResolver() {
CookieLocaleResolver cookieLocaleResolver = new CookieLocaleResolver();
cookieLocaleResolver.setDefaultLocale(StringUtils.parseLocaleString("en"));
return cookieLocaleResolver;
}
#Bean
public ServletContextTemplateResolver templateResolver() {
ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".html");
//NB, selecting HTML5 as the template mode.
resolver.setTemplateMode("HTML5");
resolver.setCacheable(false);
return resolver;
}
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver(templateResolver());
engine.setMessageResolver(messageResolver());
engine.addDialect(new LayoutDialect());
return engine;
}
#Bean
public ViewResolver viewResolver() {
ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
viewResolver.setTemplateEngine(templateEngine());
viewResolver.setOrder(1);
viewResolver.setViewNames(new String[]{"*"});
viewResolver.setCache(false);
return viewResolver;
}
#Bean
public IMessageResolver messageResolver() {
SpringMessageResolver messageResolver = new SpringMessageResolver();
messageResolver.setMessageSource(messageSource());
return messageResolver;
}
#Override
public void addFormatters(FormatterRegistry registry) {
super.addFormatters(registry);
registry.addFormatter(new DateFormatter());
}
#Bean
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
messageSource.setBasename("/WEB-INF/messages/messages");
// if true, the key of the message will be displayed if the key is not
// found, instead of throwing a NoSuchMessageException
messageSource.setUseCodeAsDefaultMessage(true);
messageSource.setDefaultEncoding("UTF-8");
// # -1 : never reload, 0 always reload
messageSource.setCacheSeconds(0);
return messageSource;
}
}
And here is the code of my Custom DateFormatter :
public class DateFormatter implements Formatter<Date> {
#Autowired
private MessageSource messageSource;
public DateFormatter() {
super();
}
public Date parse(final String text, final Locale locale) throws ParseException {
final SimpleDateFormat dateFormat = createDateFormat(locale);
return dateFormat.parse(text);
}
public String print(final Date object, final Locale locale) {
final SimpleDateFormat dateFormat = createDateFormat(locale);
return dateFormat.format(object);
}
private SimpleDateFormat createDateFormat(final Locale locale) {
//The following line is not working (nullPointerException on messageSource)
//final String format = this.messageSource.getMessage("date.format", null, locale);
//The following line is working :
final String format = "dd/MM/yyyy";
final SimpleDateFormat dateFormat = new SimpleDateFormat(format);
dateFormat.setLenient(false);
return dateFormat;
}
}
My question is : how can I add a custom formatter that will be able to use #Autowired elements ?
The xml configuration is this one :
<?xml version="1.0" encoding="UTF-8"?>
<beans ...>
...
<mvc:annotation-driven conversion-service="conversionService" />
...
<!-- **************************************************************** -->
<!-- CONVERSION SERVICE -->
<!-- Standard Spring formatting-enabled implementation -->
<!-- **************************************************************** -->
<bean id="conversionService"
class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<property name="formatters">
<set>
<bean class="thymeleafexamples.stsm.web.conversion.VarietyFormatter" />
<bean class="thymeleafexamples.stsm.web.conversion.DateFormatter" />
</set>
</property>
</bean>
...
</beans>
I tried to uset the following configuration in WebConfig class :
#Bean
public FormattingConversionServiceFactoryBean conversionService() {
FormattingConversionServiceFactoryBean conversionService = new FormattingConversionServiceFactoryBean();
Set<Formatter<?>> formatters = new TreeSet<Formatter<?>>();
formatters.add(new DateFormatter());
conversionService.setFormatters(formatters);
return conversionService;
}
But in this case, the formatter is not taken into account in my application.
Thanks in advance,
Antoine.
Add this to your WebMvcConfigurerAdapter
#Override
public void addFormatters(FormatterRegistry registry) {
registry.addFormatter(dateFormatter);
}
#Autowired
private DateFormatter dateFormatter;
#Bean
public DateFormatter dateFormatter() {
return new DateFormatter("dd/MM/yyyy");
}
I used the following configuration class and was able to get the custom formatter to be called. I have not been able to get the messageSource to be passed in, it is always null as the auto-configure bean is created later in the application startup.
#Configuration
public class ThymeleafConfig {
#Autowired
private MessageSource messageSource;
#Bean
public SpringSecurityDialect securityDialect() {
return new SpringSecurityDialect();
}
#Bean
public ConversionService conversionService() {
DefaultFormattingConversionService conversionService = new DefaultFormattingConversionService( false );
conversionService.addFormatter( dateFormatter() );
return conversionService;
}
#Bean
public DateFormatter dateFormatter() {
return new DateFormatter( messageSource );
}
}
You also need to make sure in your template that you use the double brackets around the field. i.e.
<td th:text="${{user.createDate}}">12-MAR-2015</td>
