Question

在我的Spring MVC应用程序中，我使用了Dandelion Datatables 0.10.1，由于一些性能问题，我决定按照官方迁移指南将版本升级到1.0.1：

http://dandelion.github.io/components/datatables/1.0.0/docs/from-0.10.x-to-1.x.html

我已经包含了所有必需的Maven依赖项，相应地配置了web.xml以使用Servlet 3.0版本但是当我尝试运行appplication时，我在dandelionFilter加载期间遇到以下异常。任何帮助表示赞赏。

Jackson-Core 2.3中添加了严格的重复检测功能。见http://fasterxml.github.io/jackson-core/javadoc/2.3.0/com/fasterxml/jackson/core/JsonParser.Feature.html#STRICT_DUPLICATE_DETECTION

如果可能，您应该将此依赖关系更新为v2.3.x minimum。
