public interface MultiFieldValidator
Interface that performs the correlation input check of multiple fields.
To execute the input check as per the dependency relationship between multiple fields of action form
in the presentation layer, create the class in which this interface is implemented.
In validate(String, String[])
method,
the first argument is the value to be validated and second argument is the value of dependent field
passed as an array. Returns false
when there is a validation error.
Please note that field to be validated can be passed as null
or blank character.
Since there is no default error message for this validation rule, message should always be set in validation.xml
.
*This validation rule does not support JavaScript check.
At the time of validating if the value in value field of action form is greater than the value in value1 field
and less than the value in value2 field, perform the implementation and settings as follows.
MultiFieldValidator
public boolean validate(String value, String[] fields) {
int value0 = Integer.parseInt(value);
int value1 = Integer.parseInt(fields[0]);
int value2 = Integer.parseInt(fields[1]);
return (value1 <= value0 && value2 >= value0);
}
