First paste the exception keyword

Describe the abnormal request again. Local, testing, formal three environments are no problem, foreign use can not be saved, view logs, found to report errors. So Baidu Google a few, there are the following explanations:

The YYYY-MM-DD format, which is not a standard time display format in foreign countries, struts interpretation is for input, which type is recently converted, such that the date of the format is mistaken for a string.

Online Professors ' solutions are:

1, build a conversion method, plus the configuration file, all the string to date are converted by this tool class.

2, the character encoding of the system from lang= "en_US". UTF-8 ", modified to: lang=" ZH_CN. UTF-8 "

3, also say with plug-in can, such as My97datepicker (my project itself is using this plugin, so I think this solution is not advisable)

4, on the JSP page with Java.util.Date first turn type (think it will not work)

Interested friends can try.

I chose the third workaround, defining a string datestr, receiving input from the form, and then

String Datestr;
New SimpleDateFormat ("Yyyy-mm-dd");D ate Date= sdf.parse (datestr); merchant.setdatetime (date);

This approach is simple, does not affect the global configuration, generally does not introduce new errors, that is, if the date input is more, it will cause a lot of duplicate code.
