I have wierd issue with Spring MVC and thymeleaf. When I run my web application I get random crash from time to time. Sometimes all works just fine but sometimes I get something like that:

It tells me that I dont have SpringTemplateEngine bean but I have it in my configuration:

...
imports
...
@Configuration
@EnableWebMvc
@ComponentScan("com.myapp.controllers")
public class WebConfiguration extends WebMvcConfigurerAdapter {

    private static final String TEMPLATE_RESOLVER_PREFIX = "/WEB-INF/templates/";
    private static final String TEMPLATE_RESOLVER_SUFFIX = ".html";
    private static final String TEMPLATE_RESOLVER_TEMPLATE_MODE = "HTML5";

    @Bean
    public ViewResolver viewResolver(SpringTemplateEngine templateEngine) {
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(templateEngine);

        return viewResolver;
    }

    @Bean
    public TemplateEngine templateEngine(TemplateResolver templateResolver) {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver);

        return templateEngine;
    }

    @Bean
    public TemplateResolver templateResolver() {
        TemplateResolver templateResolver = new ServletContextTemplateResolver();
        templateResolver.setPrefix(TEMPLATE_RESOLVER_PREFIX);
        templateResolver.setSuffix(TEMPLATE_RESOLVER_SUFFIX);
        templateResolver.setTemplateMode(TEMPLATE_RESOLVER_TEMPLATE_MODE);

        return templateResolver;
    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.
}

I have also thymeleaf in my .pom:

The most weird thing is that it crash totally randomly. It works just fine but after couple builds it starts crashing with every next build. When it start crashing I remove maven build "target" directory and Invalidate cache and Restart IntelliJ Idea. Have you any idea what is wrong?

PS. I use IntellijIdea 13.1.6.

People also ask

Is Thymeleaf supported by Spring MVC?

Thymeleaf offers a set of Spring integrations that allow you to use it as a fully-featured substitute for JSP in Spring MVC applications.

Is Thymeleaf faster than JSP?

From what I read, Thymeleaf is pretty slow compared to other templating languages, while JSP is very fast, with FreeMarker and Velocity coming close. However, Thymeleaf supports natural templates (templates that will render nicely in your browser even if you don't run them through the template engine).

Is Thymeleaf fully integrated with Spring?

It provides full integration with Spring Framework. It applies a set of transformations to template files in order to display data or text produced by the application. It is appropriate for serving XHTML/HTML5 in web applications. The goal of Thymeleaf is to provide a stylish and well-formed way of creating templates.

Is Thymeleaf a MVC?

1. Overview. Thymeleaf is a Java template engine for processing and creating HTML, XML, JavaScript, CSS and text. In this tutorial, we will discuss how to use Thymeleaf with Spring along with some basic use cases in the view layer of a Spring MVC application.

Maybe you're hitting some subtle dependency issue.

It is advised to declare inter-beans dependencies like this:

...
imports
...
@Configuration
@EnableWebMvc
@ComponentScan("com.myapp.controllers")
public class WebConfiguration extends WebMvcConfigurerAdapter {

    private static final String TEMPLATE_RESOLVER_PREFIX = "/WEB-INF/templates/";
    private static final String TEMPLATE_RESOLVER_SUFFIX = ".html";
    private static final String TEMPLATE_RESOLVER_TEMPLATE_MODE = "HTML5";

    @Bean
    public ViewResolver viewResolver() {
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(templateEngine());

        return viewResolver;
    }

    @Bean
    public TemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());

        return templateEngine;
    }

    @Bean
    public TemplateResolver templateResolver() {
        TemplateResolver templateResolver = new ServletContextTemplateResolver();
        templateResolver.setPrefix(TEMPLATE_RESOLVER_PREFIX);
        templateResolver.setSuffix(TEMPLATE_RESOLVER_SUFFIX);
        templateResolver.setTemplateMode(TEMPLATE_RESOLVER_TEMPLATE_MODE);

        return templateResolver;
    }

The first thing I'd check is that you haven't got multiple versions of the same library on the classpath because this can cause really confusing issues.

Maven is supposed to resolve this but I know that IDEA has some issues with conflicting dependency versions when using Gradle so it may be the case for Maven too.

To check this, expand the External Libraries "folder" in the project view and check that you have only got one entry for each library.
