SpringMVC+Thymeleaf ,error message is : template might not exist or might not be accessible by any of the configured Template Resolvers

I've read the other answers, but no matter，thanks

Spring:

<bean id="templateEngine" class="org.thymeleaf.spring3.SpringTemplateEngine">
    <property name="templateResolver" ref="templateResolver" />
</bean>

<bean class="org.thymeleaf.spring3.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine" />
    <property name="order" value="1" />
</bean>

pom.xml:

org.thymeleaf.exceptions.TemplateInputException: Error resolving template "login.html", template might not exist or might not be accessible by any of the configured Template Resolvers

Answer 1

Do you need a template resolver?

Try something like this:

<bean id="templateResolver"
      class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <property name="prefix" value="/WEB-INF/" />
    <property name="templateMode" value="HTML5" />
 </bean>

Make sure that /path/after/web-inf/login.html is being returned by a Spring MVC controller.

Answer 2

You are likely missing the "suffix" property within the templateResolver configuration. It should be best practice to use both a path "prefix" (where the file is located) and a "suffix" (the file extension - otherwise thymeleaf tries to resolve just "login" w/o an extension) within the template resolver configuration. Like so:

<beans:bean id="templateResolver" class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <beans:property name="prefix" value="/WEB-INF/views/"/>
    <beans:property name="suffix" value=".html"/>
    <beans:property name="templateMode" value="HTML5"/>
    <beans:property name="cacheable" value="false"/> <!-- Development only -->
</beans:bean>

And requesting the login view within a controller does not include the file extension.

@RequestMapping(value = "/login")
public String login(HttpSession session) {
    // do stuff

    // Thymeleaf (delegated by springmvc) will request the "login" view at which 
    // point the prefix and suffix are added to resolve the template location. 
    return "login"; 
}

So based on this configuration and within a maven-based project, the login.html should be located at

${project_home}/src/main/webapp/WEB-INF/views/login.html
