Question

以下是数据映射器中映射的部分

dateTimeFormatter = new java.text.SimpleDateFormat（“yyyy-MM-dd'T'HH：mm：ss”）; output.Date_of_Rate_Float__c =（isnull（input.Date_of_Rate_Float）？null：dateTimeFormatter.format（input.Date_of_Rate_Float））; output.Loan_Create_Date__c =（isnull（input.loan_create_date）？null：dateTimeFormatter.format（input.loan_create_date））; output.Estimated_Closing_Date__c =（isnull（input.estimated_closing_date）？null：dateTimeFormatter.format（input.estimated_closing_date））;

这会引发以下异常

1. DateConverter does not support default String to 'Date' conversion. (org.apache.commons.beanutils.ConversionException)
  org.apache.commons.beanutils.converters.DateTimeConverter:468 (null)
