Format Time using initBinder

Question

I need to catch the time with the "hh:mm" format but it is not working, follow the error also to better specify:

Answer 1

According to the error message:

... [Failed to Convert Property value of type 'java.lang.String' to required type 'java.util.Date' for Property 'final time'; nested Exception is java.lang.Illegalargumentexception: Could not parse date: Unparseable date: "17:20"

That means that the String with the value "17:20" was passed to the SimpleDateFormat that you created, but it was not possible to do the Parsing.

Considering the SimpleDateFormat created in your method initBinder:

// SimpleDateFormat que você criou
SimpleDateFormat dateFormat = new SimpleDateFormat("hh:mm");
dateFormat.setLenient(false);

// tenta fazer o parsing de 17:20
Date date = dateFormat.parse("17:20");

This code throws an exception:

java.text.Parseexception: Unparseable date: "17:20"

This is because hh corresponds to the field Hour in am/pm, with values between 1 and 12 (for example, the 5 it can be as much 5 in the morning as 5 in the afternoon).

This SimpleDateFormat until would accept values greater than 12 for the hours, but how you used setLenient(false), this causes only values between 1 and 12 to be accepted, and any other bid exception.

As you are receiving values greater than 12, use HH (capital letters) in order to accept values between 0 and 23 (5 it’s 5:00 in the morning and 17 it’s 5 in the afternoon):

// usar HH para as horas (em vez de hh)
SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm");
dateFormat.setLenient(false);
// agora sim faz o parsing sem lançar exceção
Date date = dateFormat.parse("17:20");

Use the right field

By default, SimpleDateFormat is lenient, which means it accepts any values and tries to find a way to adjust them (what can generate some pretty strange results if you don’t take care).

Using setLenient(false), this permissive mode is switched off and the class becomes more restrictive, accepting only values within the allowed range for each field. And if you look at documentation, you will see that there are 4 fields for the hour, each one represented by a different letter and with a specific range of values:

Letra   Nome do campo/valores
H       Hour in day (0-23)
k       Hour in day (1-24)
K       Hour in am/pm (0-11)
h       Hour in am/pm (1-12)

Like you were wearing hh (lower case), only values between 1 and 12 are allowed. When trying to do "17:20", the exception occurs, since 17 is outside the range of valid values for the field h.

Note that in your case you can use HH (capital), or kk (lower case): the first accepts midnight as zero, and the second as 24. Check in your use cases how you receive this value and use the field that is most suitable.
