java.lang.Object
com.opensymphony.xwork.validator.validators.ValidatorSupport
com.opensymphony.xwork.validator.validators.FieldValidatorSupport
com.opensymphony.xwork.validator.validators.RequiredStringValidator
- All Implemented Interfaces:
- FieldValidator, ShortCircuitableValidator, Validator
- public class RequiredStringValidator
- extends FieldValidatorSupport
RequiredStringValidator checks that a String field is non-null and has a length > 0.
(i.e. it isn't ""). The "trim" parameter determines whether it will trim
the String before performing the length check. If unspecified, the String will be trimmed.
- fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
- trim - trim the field name value before validating (default is true)
<validators>
<!-- Plain-Validator Syntax -->
<validator type="requiredstring">
<param name="fieldName">username</param>
<param name="trim">true</param>
<message>username is required</message>
</validator>
<!-- Field-Validator Syntax -->
<field name="username">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message>username is required</message>
</field-validator>
</field>
</validators>
