java - bootstrap - thymeleaf spring boot que es
Spring Boot Security+Thymeleaf: falta la clase IProcessorDialect (3)
Estoy tratando de integrar el dialecto de seguridad Thymeleaf (como sec: authorize tag) en una aplicación Spring Boot + Spring Security que funciona correctamente.
Después de algunas investigaciones, encontré que la solución para activar es:
Agregue la dependencia en el archivo POM:
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity4</artifactId>
<version>3.0.0.RELEASE</version>
</dependency>
e incluye la etiqueta en la parte superior del archivo de plantilla:
<html xmlns:th="http://www.thymeleaf.org" lang="en"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
Hasta ahora tan bueno. Se encuentra dependencia, las etiquetas reconocidas en el marcado.
Sin embargo, no se tienen en cuenta y aparecen en el HTML final generado.
Debido a un problema en la configuración automática de Spring Boot que no se habilita, parece ser necesario agregar manualmente un SpringSecurityDialect Bean a una clase @Configuration para habilitarlo (varias preguntas encontradas en StackOverflow han sido resueltas por esto):
@Bean
public SpringSecurityDialect securityDialect() {
return new SpringSecurityDialect();
}
Esto es lo que causa un problema: cuando agrego este Bean a mi configuración de inicio de Spring, genera una excepción porque no puede encontrar la clase org.thymeleaf.dialect.IProcessorDialect . Aquí está el 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)
¿Qué me estoy perdiendo? ¿Es este un error que viene de Thymeleaf? Bota de primavera? ¿Mi propio código? Gracias de antemano por tu ayuda !
Aquí están algunos de mis archivos preocupados por mi problema:
Aplicacion.java
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}

SpringApplication.run(Application.class, args);
}
@Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() {
@Override

SecurityConstraint securityConstraint = new SecurityConstraint();
securityConstraint.setUserConstraint("CONFIDENTIAL");
SecurityCollection collection = new SecurityCollection();
collection.addPattern("/*");
securityConstraint.addCollection(collection);
context.addConstraint(securityConstraint);
}
};
tomcat.addAdditionalTomcatConnectors(initiateHttpConnector());
return tomcat;
}

connector.setRedirectPort(8443);
return connector;
}

Esto me salva la vida.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
Utilizando: Maven 3.5.0
Java 1.8.0_152
Spring: https://start.spring.io -> Spring Boot :: (v2.0.0.BUILD-SNAPSHOT)
Finalmente, funciona con las configuraciones predeterminadas de arranque de primavera de la siguiente manera: versión de arranque de resorte 1.5.8.RELEASE
<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>
Esto agregará
- Thymeleaf-spring4 versión 2.1.5.RELEASE
- Vuelta de hoja de timbo 2.1.5.
- Thymeleaf-extra-springsecurity4 versión 2.1.3.RELEASE
Seguridad de primavera 4.2.3.RELEASE
Asegúrese de ignorar la definición de bean SpringSecurityDialect en el archivo de configuración, no funcionará. solo usa el valor predeterminado a menos que necesites hacer otras cosas.
Gracias por el comentario útil de M. Deinum!
De hecho, parece que "Thymeleaf Extras for Spring Security 4" versión 3.0.0 aún no es compatible.
He cambiado la versión de dependencia de Maven de Thymeleaf thymeleaf-extras-springsecurity4 en mi archivo POM de 3.0.0 a la última versión 2.xx (2.1.2 en el momento de esta publicación), y solucioné el problema.
Desde:
<!-- 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>
a:
<!-- 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>
El problema ya no aparece, la aplicación web se inicia correctamente y las etiquetas se reconocen :)
