Validation¶
Client side¶
To make client side validation need define rules for special form (see jQuery Validation Plugin).
Example of how to do it you can find at restore_password_validation.js
30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 | $('#restorePasswordFormEmail').validate({
rules: {
email: {
required: true,
email: true,
checkNotUnique: "/restore_password/emailunique"
}
},
messages: {
email: {
required: "Email is required",
email: "Email not valid",
checkNotUnique: "User with this email does not exist"
}
}
});

Server side¶
Server side validation based on class GeneralValidator. It uses interface Validator.
For API object validation need override method getFieldsConstraints() for example in IncidentRestControllerImpl
77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 | @Override
protected Map<String, Map<GeneralValidator.Constraint, String>> getFieldsConstraints() {
Map<String, Map<GeneralValidator.Constraint, String>> fieldsConstraints = super.getFieldsConstraints();
GeneralValidator.buildField(fieldsConstraints, "title",
new AbstractMap.SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null),
new AbstractMap.SimpleEntry<>(GeneralValidator.Constraint.MIN, "4")
);
GeneralValidator.buildField(fieldsConstraints, "description",
new AbstractMap.SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null),
new AbstractMap.SimpleEntry<>(GeneralValidator.Constraint.MIN, "4")
);
GeneralValidator.buildField(fieldsConstraints, "categories",
new AbstractMap.SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null)
);
GeneralValidator.buildField(fieldsConstraints, "pupils",
new AbstractMap.SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null)
);
GeneralValidator.buildField(fieldsConstraints, "priority",
new AbstractMap.SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null)
);
return fieldsConstraints;
}

Example how create validation from AdminController for form parameters.
236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 | Map<String, Map<GeneralValidator.Constraint, String>> constraints = new HashMap<>();
GeneralValidator.buildField(constraints, "password",
new SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null),
new SimpleEntry<>(GeneralValidator.Constraint.MIN, "4"),
new SimpleEntry<>(GeneralValidator.Constraint.MATCH_WITH, "confirmPassword")
);
GeneralValidator.buildField(constraints, "person.firstName",
new SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null),
new SimpleEntry<>(GeneralValidator.Constraint.MIN, "4")
);
GeneralValidator.buildField(constraints, "person.lastName",
new SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null),
new SimpleEntry<>(GeneralValidator.Constraint.MIN, "4")
);
GeneralValidator.buildField(constraints, "person.emails",
new SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null),
new SimpleEntry<>(GeneralValidator.Constraint.REGEX, GeneralValidator.EMAIL_PATTERN)
);
GeneralValidator.buildField(constraints, "person.phones",
new SimpleEntry<>(GeneralValidator.Constraint.NOT_NULL_OR_EMPTY, null),
new SimpleEntry<>(GeneralValidator.Constraint.MIN, "8")
);
if (userService.findByUsername(user.getUsername()) != null) {
bindingResult.reject(null, "username not unique");
}
if (userService.findByEmail(email) != null) {
bindingResult.reject(null, "email not unique");
}
new GeneralValidator(constraints).invoke(user, bindingResult);
