Hi with spring 3.0.4 and Hibernate validator 4.1.0.Final, I created a custom validator for validating password and confirmPassword fields.
However the validator thrown the following exception:

Here is the bean class:
Code:
@CompareStrings(propertyNames={"password", "confirmPassword"}, message="Password and Comfirm Password must be matched.")
public class AdminSignupBean {
private String password = "";
private String confirmPassword = "";
private String emailAddress = "";
private String firstName = "";
private String lastName = "";
private String gender = "M";
private String loginName = "";
private String address1 = "";
private String address2 = "";
private String suburb = "";
private String state = "";
private String postcode = "";
private String phone = "";
...
<settings and getters>
validator class:
Code:
public class CompareStringsValidator implements ConstraintValidator<CompareStrings, Object> {
public enum StringComparisonMode {
EQUAL, EQUAL_IGNORE_CASE, NOT_EQUAL, NOT_EQUAL_IGNORE_CASE
}
private String[] propertyNames;
private StringComparisonMode comparisonMode;
private boolean allowNull;
@Override
public void initialize(CompareStrings constraintAnnotation) {
this.propertyNames = constraintAnnotation.propertyNames();
this.comparisonMode = constraintAnnotation.matchMode();
this.allowNull = constraintAnnotation.allowNull();
}
@Override
public boolean isValid(Object target, ConstraintValidatorContext context) {
boolean isValid = true;
List<String> propertyValues = new ArrayList<String> (propertyNames.length);
for(int i=0; i<propertyNames.length; i++) {
String propertyValue = ConstraintValidatorHelper.getPropertyValue(String.class, propertyNames[i], target);
if(propertyValue == null) {
if(!allowNull) {
isValid = false;
break;
}
} else {
propertyValues.add(propertyValue);
}
}
if(isValid) {
isValid = ConstraintValidatorHelper.isValid(propertyValues, comparisonMode);
}
if (!isValid) {
/*
* if custom message was provided, don't touch it, otherwise build the
* default message
*/
String message = context.getDefaultConstraintMessageTemplate();
message = (message.isEmpty()) ? ConstraintValidatorHelper.resolveMessage(propertyNames, comparisonMode) : message;
context.disableDefaultConstraintViolation();
ConstraintViolationBuilder violationBuilder = context.buildConstraintViolationWithTemplate(message);
for (String propertyName : propertyNames) {
NodeBuilderDefinedContext nbdc = violationBuilder.addNode(propertyName);
nbdc.addConstraintViolation();
}
}
return isValid;
}
}
Controller class:
Code:
public String submitProduct(HttpServletRequest req, Model model,
@ModelAttribute("adminsignup") @Valid final AdminSignupBean adminsignup,
BindingResult result, ModelMap map)
{
UUID pbid=adminsignup.getPbid();
logger.debug("====adminsignup:"+adminsignup.toString());
if (result.hasErrors()) {
AdminSignupBean admin = products.get(pbid);
req.getSession().setAttribute("pbid", pbid);
BeanUtils.copyProperties(adminsignup, admin, new String[] {"pbid", "mpf", "password", "confirmPassword"});
map.addAttribute("adminsignupbean",admin);
return "adminsignup/createadmin";
}
Set<ConstraintViolation<AdminSignupBean>> violations
= validatorFactory.getValidator().validate(adminsignup);
for(ConstraintViolation<AdminSignupBean> violation : violations) {
logger.debug("=========Violation Message:- " + violation.getMessage());
}
if (!violations.isEmpty()) {
logger.debug("=====violations messages:"+violations.toString());
AdminSignupBean admin = products.get(pbid);
req.getSession().setAttribute("pbid", pbid);
BeanUtils.copyProperties(adminsignup, admin, new String[] {"pbid", "mpf", "password", "confirmPassword"});
map.addAttribute("adminsignupbean",admin);
return "adminsignup/createadmin";
}
Any suggestion is very appreciated.
Thanks
