尝试在STORM Trident中将XML转换为JSON我的代码在Storm 0.9.1版本中运行良好，现在我们升级到Storm 0.10.0的最新版本，如果您对原因有任何了解，则会收到以下错误，请告诉我？

最佳答案
看起来您有许多版本的 jackson jar，并且您的类路径在运行时引用了2.6之前的某些 jackson jar。
从版本2.6开始，类ResolvedType引入了isReferenceType()。请引用以下链接:
http://googleweblight.com/?lite_url=http://fasterxml.github.io/jackson-core/javadoc/2.6/com/fasterxml/jackson/core/type/ResolvedType.html&ei=ochB8Ipc&lc=en-IN&geid=10&s=1&m=71&ts=1454581842&sig=ALL1Aj7I2EAu3AoKmOu6FKbtFTTuKU02Bg#a-isReferenceType()
请确保在运行时引用正确的版本或更高版本。如果不需要，您可以删除/删除较旧的 jackson jar 。
希望这可以帮助。
