Spring Boot Security + Thymeleaf : IProcessorDialect class missing

Tags:

thymeleaf

I'm trying to integrate the Thymeleaf security dialect (such as sec:authorize tag) into a Spring Boot + Spring Security application that is working properly.

After some research I found that the solution to activate that is to:

Add the dependency in the POM file:

<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity4</artifactId>
    <version>3.0.0.RELEASE</version>
</dependency>

and include the tag at the top of the template file:

<html   xmlns:th="http://www.thymeleaf.org" lang="en"
        xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

So far, so good. Dependency is found, the tags recognized in the markup.

However they're not taken into account and appear in the final HTML generated.

Because of a problem in the Spring Boot auto-configuration which doesn't enable, it seems to be necessary to manually add a SpringSecurityDialect Bean to one @Configuration class to enable it (several questions found on StackOverflow have been solved by this):

@Bean
    public SpringSecurityDialect securityDialect() {
        return new SpringSecurityDialect();
    }

This is what causes a problem: when I add this Bean into my Spring Boot Configuration, it raises an Exception because it can't find the class org.thymeleaf.dialect.IProcessorDialect. Here is the error:

> java.lang.IllegalStateException: Could not evaluate condition on
> org.springframework.boot.autoconfigure.PropertyPlaceholderAutoConfiguration#propertySourcesPlaceholderConfigurer
> due to org/thymeleaf/dialect/IProcessorDialect not found. Make sure
> your own configuration does not rely on that class. This can also
> happen if you are @ComponentScanning a springframework package (e.g.
> if you put a @ComponentScan in the default package by mistake)

What am I missing? Is this an error coming from Thymeleaf? Spring Boot? My own code? Thanks in advance for your help !

Here are some of my files concerned by my issue:

Application.java

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
      public EmbeddedServletContainerFactory servletContainer() {
        TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() {
            @Override
            protected void postProcessContext(Context context) {
              SecurityConstraint securityConstraint = new SecurityConstraint();
              securityConstraint.setUserConstraint("CONFIDENTIAL");
              SecurityCollection collection = new SecurityCollection();
              collection.addPattern("/*");
              securityConstraint.addCollection(collection);
              context.addConstraint(securityConstraint);
            }
          };

        tomcat.addAdditionalTomcatConnectors(initiateHttpConnector());
        return tomcat;
      }

      private Connector initiateHttpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setPort(8080);
        connector.setSecure(false);
        connector.setRedirectPort(8443);

        return connector;
      }
}

WebMvcConfig.java

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.thymeleaf.extras.springsecurity4.dialect.SpringSecurityDialect;

@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

    /**
     * Configure relationships between URLs and view names
     */
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
    }

    @Bean
    public SpringSecurityDialect securityDialect() {
        return new SpringSecurityDialect();
    }
}

Thymeleaf template:

<!DOCTYPE html>
<html   xmlns:th="http://www.thymeleaf.org" lang="en"
        xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

....

<div sec:authorize="isAuthenticated()">
    LOGGED IN
</div>
<div sec:authorize="isAnonymous()">
    ANONYMOUS
</div>

....

Thanks for M. Deinum helpful comment!

It appears indeed that "Thymeleaf Extras for Spring Security 4" version 3.0.0 isn't supported yet.

I have changed the Maven dependency version of Thymeleaf thymeleaf-extras-springsecurity4 in my POM file from 3.0.0 to the latest 2.x.x version (2.1.2 at the moment of this post), and it fixed the issue.

From: 

    <!-- http://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 -->
    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity4</artifactId>
        <version>3.0.0.RELEASE</version>
    </dependency>

to:

    <!-- http://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 -->
    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity4</artifactId>
        <version>2.1.2.RELEASE</version>
    </dependency>

The issue doesn't appear anymore, the web application starts properly, and the tags are recognised :)
