Spring Boot Security + Thymeleaf：IProcessorDialectクラスがない

Thymeleafセキュリティ方言（sec：authorizeタグなど）を、正常に機能しているSpring Boot + Spring Securityアプリケーションに統合しようとしています。

いくつかの調査の後、私はそれを活性化する解決策が以下であることを発見しました：

POMファイルに依存関係を追加します。

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

テンプレートファイルの先頭にタグを含めます。

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

ここまでは順調ですね。依存関係が見つかり、タグがマークアップで認識されます。

ただし、それらは考慮されず、生成された最終的なHTMLに表示されます。

有効にしないSpring Boot自動設定の問題のため、手動でSpringSecurityDialect Beanを1つの@Configurationクラスに追加して有効にする必要があるようです（StackOverflowで見つかったいくつかの質問にはこれによって解決されました）：

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

これが問題の原因です。このBeanをSpringブート構成に追加すると、クラスorg.thymeleaf.dialect.IProcessorDialectが見つからないため、例外が発生します。ここにエラーがあります：

> 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)

何が欠けていますか？これはThymeleafからのエラーですか？Spring Boot？自分のコード？助けてくれてありがとう！

これは私の問題に関係する私のファイルの一部です：

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テンプレート：

<!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>

....

M. Deinumの役立つコメントをありがとう！

実際、「Thymeleaf Extras for Spring Security 4」バージョン3.0.0はまだサポートされていないようです。

私のPOMファイルのThymeleafのMaven依存バージョンthymeleaf-extras-springsecurity4を3.0.0から最新の2.xxバージョン（この投稿の時点では2.1.2）に変更しました。問題を修正しました。

から：

    <!-- 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>

に：

    <!-- 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>

問題は発生しなくなり、Webアプリケーションが正常に起動し、タグが認識されます。

これは私の命を救います。

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

使用：Maven 3.5.0
Java 1.8.0_152
春： https://start.spring.io ->春のブーツ::（v2.0.0.BUILD-SNAPSHOT）

最後に、デフォルトのスプリングブート構成で次のように動作します-スプリングブートバージョン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>

これは追加されます

  • Thymeleaf-spring4バージョン2.1.5.RELEASE
  • Thymeleafバージョン2.1.5.RELEASE
  • Thymeleaf-extra-springsecurity4バージョン2.1.3.RELEASE

  • Spring-security 4.2.3.RELEASE

    設定ファイルのBean定義SpringSecurityDialectは無視してください。機能しません。他のことをする必要がない限り、デフォルトを使用してください。
