Hi friends
I'm not sure I understand the use of custom converters:
If for example I have 2 VO's and each has a Timestamp property. But -
each one takes a different date format from the user. Do I need a
different StringToTimestamp converter for each one? If yes - how does
BeanUtils.copyProperties() know which converter to use (both the above
properties are the same type - Timestamp)?
It does not. Frankly, this is a limitation of the BeanUtils design
model. It assumes for any given process (instance of BeanUtils), a
single conversion strategy applies to all objects of a given type.
I have solved this sometimes by writing a Converter which expects a
few specific variations of a date format and then tests the string
length to look up the format string -- obviously this is imperfect,
but it may work for you.
(something like this:
if (str.length() == 10) {
// parse date using "mm/dd/yyyy"
} else if (str.length() == 8) {
// parse date using "hh:mm a"
} else {
throw new IllegalArgumentException("Unrecognized date format");
}
