Spring Boot Security + Thymeleaf：缺少IProcessorDialect类 [英] Spring Boot Security + Thymeleaf : IProcessorDialect class missing
本文介绍了Spring Boot Security + Thymeleaf：缺少IProcessorDialect类的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将Thymeleaf安全方言（例如 sec：authorize 标签）集成到正常运行的Spring Boot + Spring Security应用程序中。
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.
经过一些研究后，我发现激活的解决方案是：
After some research I found that the solution to activate that is to:
在POM文件中添加依赖项：
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>
并在模板文件顶部包含标签：
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">
到目前为止，非常好。找到依赖关系，标记中标记的标记。
So far, so good. Dependency is found, the tags recognized in the markup.
但是它们不会被考虑在内并显示在生成的最终HTML中。
由于Spring Boot自动配置中的一个问题没有启用，似乎有必要手动添加 SpringSecurityDialect Bean到一个@Configuration类启用它（StackOverflow上的几个问题已经解决了）：
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();
}
这是导致问题的原因：当我将这个Bean添加到我的Spring Boot中时配置，它引发了一个异常，因为它找不到类 org.thymeleaf.dialect.IProcessorDialect 。这是错误：
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)
我错过了什么？这是来自Thymeleaf的错误吗？春季靴子？我自己的代码？在此先感谢您的帮助！
以下是我的一些文件：
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

}

推荐答案
感谢M. Deinum的有用评论！
Thanks for M. Deinum helpful comment!
看来确实Spring Security 4的Thymeleaf Extras版本3.0.0 isn尚未支持。
It appears indeed that "Thymeleaf Extras for Spring Security 4" version 3.0.0 isn't supported yet.
我已将我的POM文件中的Thymeleaf thymeleaf-extras-springsecurity4 的Maven依赖版本从3.0.0更改为最新的2.xx版本（本文发布时为2.1.2），它解决了问题。
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.
来自：
<!-- http://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 -->
<dependency>

此问题不再出现，Web应用程序正常启动，标签被识别:)
The issue doesn't appear anymore, the web application starts properly, and the tags are recognised :)
