Validation is a small library for validation purposes.

BigDecimal Validator

The BigDecimal Validator is a small library to validate java.math.BigDecimal

Features

• Validation of BigDecimals via Service or Annotation
  • Maximal/Minimal decimal places
  • Maximal fractional places
  • Maximal/Minimal value

#Prerequisites

• Maven 3 or higher
• JDK 7 or higher

Examples

Annotation driven

Test if the value of an attribute of an entity and the number of the decimal and fractional places are in the correct range.

public class Price {

    @BigDecimalValidate(
     minDecimalPlaces = 1,
     maxDecimalPlaces = 3,
     maxFractionalPlaces = 2,
     minValue = 0.00,
     maxValue = 500.00
    )
    private BigDecimal value;
    
    // Getters and Setters
}

You can also specify the message that would be shown if the validation would throw an error by adding the message property.

Service driven

public void function() {

 BigDecimalValidator validator = new BigDecimalValidator();
 
 BigDecimalValidationRules rules = new BigDecimalValidationRules.Builder()
  .minDecimalPlaces(1)
  .maxDecimalPlaces(3)
  .maxFractionalPlaces(2)
  .minValue(0.00)
  .maxValue(500.00)
  .build();
 
 BigDecimalValidationResult result = validator.validate(new BigDecimal("250.00"), rules);
 
 if(!result.isValid()) {
  System.out.println(result.getFailMessage());
 }
}
