使用不同日期格式的jsp插入日期字段到數據庫

Question

我想將日期字段保存到mysql表中。 我的jsp表單中的日期字段格式爲MM/DD/YYY，數據庫格式爲YYYY/MM/DD。 如何從表格中檢索日期並以YYYY/MM/DD格式插入表格？

String publishdt = request.getParameter("publish"); 
if(publishdt == null) 
{ 
    publishdt = ""; 
} 
else 
{ 
    try 
     { 
      DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MM/dd/yyyy"); 
      LocalDate date = LocalDate.parse(publishdt, formatter); 
      publish = String.format("%s", date); 
     } 
    catch (DateTimeParseException exc) 
     { 
      out.println("%s is not parsable!%n"+publish); 
      throw exc;  // Rethrow the exception. 
     } 
     // 'date' has been successfully parsed 
}
