我需要运行作业执行。为了这个目标，我尝试使用JobOperator。但我遇到了一个例外：
2018-02-01 12:00:58.669 ERROR 1480 --- [io-50201-exec-4] c.s.i.l.s.o.f.ExceptionHandlerFilter : Error occurred during processing: Request processing failed; nested exception is com.thoughtworks.xstream.converters.ConversionException: Cannot construct type
---- Debugging information ----

我使用jettison 1.1代替1.3.2 link尝试了解决方案 但这并没有任何效果。我该如何解决这个问题？
已修改。以下是stacktrase。 引起：com.thoughtworks.xstream.converters.ConversionException：无法构造类型

我解决了我的问题。问题出在问题上。我用过命令：
gradlew build --refresh-dependencies
