Question

我想从Thymeleaf 2.1.3迁移到3.0.8。我更新了pom.xml文件，就像你在下面看到的最新版本的resoucres一样。如果我尝试将war文件部署到Jboss，我将收到BeanCreationException。您可以在下面找到详细的Stacktrace。

我想由于ConditionalCommentsDialect的超类构造函数中缺少属性而引发异常。 ConditionalCommentsDialect正在扩展org.thymeleaf.dialect.AbstractDialect，并且在Thymeleaf 3版本中更改了构造函数。似乎ConditionalCommentsDialect与Thymeleaf 3不兼容。那么我的假设是对的吗？任何想法如何解决这个问题？提前谢谢。

的pom.xml

Answer 1

条件评论现在作为Thymeleaf核心的一部分提供（从版本3开始）。您可以简单地删除该依赖项。

Thymeleaf从2到3的迁移因使用thymeleaf-extras-conditionalcomments而异常
