JSTL label Fmt:formatdate formatted date String to date

In one of my previous blogs:

wrote about how to convert the background date type to the foreground display, today I'm using the fourth method

<value= "&{diary.releasedate}"  type= "date"  pattern  = "Yyyy-mm-dd"/>

Appears: Unable to convert string "&{diary.releasedate}" to class ' java.util.Date ' for attribute ' value ': Property Editor N OT registered with the Propertyeditormanager exception

The reason is that although releasedate is set to the date type in entity diary, &{diary.releasedate} is taken out as a string type and cannot be converted to a date type

The output will be normal as follows

<value= "<%=new Date ()%>"  pattern= "YYYY-MM-DD"/ >

The workaround is to first parse the string to date and then format the date

<value= "${entity.ctime}"  var= "date"  pattern= " Yyyymmddhhmm "/><value=" ${date} "  pattern  = "Yyyy-mm-dd hh:mm"/>
