錯誤而使用的DataMapper在騾

映射日期拋出下面是數據映射器錯誤而使用的DataMapper在騾

dateTimeFormatter =新java.text.SimpleDateFormat中（「YYYY-MM-dd'T'HH的映射的部分：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））;

，這將引發以下異常

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

它看起來像一個空值傳遞給format方法。要了解如何使其可以「無效」，您可以查看Format a Date, allowing null

的示例我檢查了發送到Data Mapper的數據，它沒有任何空值，並且如果我刪除了數據中的Date Formatter它不會拋出錯誤。你知道爲什麼日期格式化程序導致錯誤。 – madhu 2014-10-14 10:12:36
