用电子邮件validation生成使用Apache poi的Excel表
我生成的Excel表使用apache poi电子邮件 – 这意味着生成excel后，如果用户在单元格中input电子邮件，我需要validation该电子邮件
下面是我的代码
DVConstraint EmailConstraint=null; DataValidation EmaildataValidation =null; EmailConstraint=DVConstraint.createCustomFormulaConstraint("AND(FIND("+'@'+",$A$2),FIND(.,$A$2),ISERROR(FIND( ,$A$2)))");---->getting error here only EmaildataValidation =dataValidationHelper.createValidation(EmailConstraint, addressList1); EmaildataValidation.setSuppressDropDownArrow(false); sheet.addValidationData(EmaildataValidation); 当我执行这个方法时，我得到以下错误

我尝试了很多，但无法做到。
查找函数的第一个参数是string，因此它必须被引用。 查找（“@”，..在Java中，您可以在公式之间使用转义string字符。
