胸腺从2号迁移到3号，使用胸腺附加条件注释时出现异常

Question

我想从Thymelaf 2.1.3迁移到3.0.8。我用最新版本的资源更新了pom.xml文件，如下所示。如果我试图将war文件部署到Jboss，我会得到一个BeanCreationException。您可以在下面找到详细的Stacktrace。

我猜异常是由于ConditionalCommentsDialect的超类构造函数中缺少属性而引发的。ConditionalCommentsDialect正在扩展org.thymelaf.dialect.AbstractDialect，并且在Thymelaf 3版本中更改了构造函数。似乎条件注释对话框与Thymelaf 3不兼容。那么我的假设是对的吗？有什么办法解决这个问题吗？提前谢谢。

Answer 1

条件注释现在作为Thymelaf核心的一部分提供(自版本3以来)。您可以简单地删除该依赖项。
