在开发过程中，当我尝试键入需要在批处理中运行的新创建的类时，我收到了此错误。 那个类我手动输入，因为它没有出现在批处理作业中的列表新任务表单中。 During development, I got this error, when try to type newly created class that need to be run in batch processing. That class I manually type because it was not appear in a list new task form inside batch job. 后来我发现我没有实现RunBaseBatch的canGoBatchJournal（）方法 在我的类中添加以下代码片段后，它将开始显示在批处理作业任务列表中。 Later I found that I did not implement the canGoBatchJournal() method of RunBaseBatch After adding following code snippet in my class, it will start to show in batch job task list.
