Spring Boot Security + Thymeleaf: IProcessorDialect-Klasse fehlt

Ich versuche, den Thymeleaf-Sicherheitsdialekt (wie das Tag sec: authorize) in eine Spring Boot + Spring Security-Anwendung zu integrieren, die ordnungsgemäß funktioniert.

Nach einigen Recherchen fand ich heraus, dass die Lösung zur Aktivierung darin besteht:

Fügen Sie die Abhängigkeit in der POM-Datei hinzu:

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

und fügen Sie das Tag oben in die Vorlagendatei ein:

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

So weit, ist es gut. Abhängigkeit wird gefunden, die Tags werden im Markup erkannt.

Sie werden jedoch nicht berücksichtigt und erscheinen im endgültigen generierten HTML-Code.

Aufgrund eines Problems in der Spring Boot-Autokonfiguration, das nicht aktiviert werden kann, scheint es erforderlich, manuell ein SpringSecurityDialect Bean zu einer @Configuration-Klasse hinzuzufügen, um es zu aktivieren (mehrere Fragen zu StackOverflow wurden durch gelöst.) diese):

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

Das verursacht ein Problem: Wenn ich dieses Bean in meine Spring Boot-Konfiguration einfüge, wird eine Exception ausgelöst, da es die Klasse org.thymeleaf.dialect.IProcessorDialect nicht finden kann. Hier ist der Fehler:

> 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)

Was vermisse ich? Ist das ein Fehler von Thymeleaf? Spring Boot? Mein eigener Code? Vielen Dank im Voraus für Ihre Hilfe !

Hier sind einige meiner Dateien, die von meinem Problem betroffen sind:

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;
      }
}

    /**

    }

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

Danke für Ihren hilfreichen Kommentar von M. Deinum!

Es scheint tatsächlich, dass "Thymeleaf Extras für Spring Security 4" Version 3.0.0 noch nicht unterstützt wird.

Ich habe die Maven-Abhängigkeitsversion von Thymeleaf thymeleaf-extras-springsecurity4 in meiner POM-Datei von 3.0.0 auf die neueste 2.xx-Version (2.1.2 zum Zeitpunkt dieses Beitrags) geändert und das Problem behoben .

Von: 

    <!-- 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>

zu:

    <!-- 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>

Das Problem wird nicht mehr angezeigt, die Webanwendung wird ordnungsgemäß gestartet und die Tags werden erkannt :)

Das rettet mein Leben.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

Verwenden von: Maven 3.5.0 
Java 1.8.0_152
Spring: https://start.spring.io -> Spring Boot :: (v2.0.0.BUILD-SNAPSHOT)

Schließlich funktioniert es mit den Standard-Federkernkonfigurationen wie folgt - Federboot Version 1.5.8. FREIGABE

 <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
    <dependency>
         <groupId>org.thymeleaf.extras</groupId>
         <artifactId>thymeleaf-extras-springsecurity4</artifactId>
    </dependency>

Dies wird hinzufügen 

  • Thymeleaf-spring4 Version 2.1.5.Freigabe
  • Thymeleaf-Version 2.1.5.FREIGABE 
  • Thymeleaf-extra-springsecurity4 Version 2.1.3.RELEASE

  • Federsicherheit 4.2.3.Freigabe

    Achten Sie darauf, die Bean-Definition SpringSecurityDialect in der Konfigurationsdatei zu ignorieren. Sie funktioniert nicht. Verwenden Sie einfach die Standardeinstellung, es sei denn, Sie müssen andere Dinge tun.
