optaplanner-examples：解組器的配置ConfigResource

我從git中克隆了optaplanner-examples來學習如何爲我的問題案例實現庫。optaplanner-examples：解組器的配置ConfigResource

我修改了示例PassionAdmissionSchedule，我只想要沒有擺動的代碼。當我想啓動解算器時，我收到了錯誤消息。

Exception in thread "main" java.lang.IllegalArgumentException: Unmarshalling of solverConfigResource (test/patientAdmissionScheduleSolverConfig.xml) fails.

-------------------------------

解算器配置是相同的。

該錯誤消息說，Java可以不加載類BedDesignationPillarSwapMoveFactory，但是爲什麼呢？

行號：你解算器XML配置的25

檢查行號25。

這是無效的：

 <moveListFactoryClass> 
      test.BedDesignationPillarPartSwapMoveFactory 
     </moveListFactoryClass>

這是有效的：

 <moveListFactoryClass>test.BedDesignationPillarPartSwapMoveFactory</moveListFactoryClass>

假定存在與該包類的Java包測試。
