Java Struts2 自定义validation验证
定义验证类，继承FieldValidatorSupport，重写validate方法即可。import com.opensymphony.xwork2.validator.ValidationException;import com.opensymphony.xwork2.validator.validators.FieldValidatorSupport;public class BadwordFilter extends FieldValidatorSupport{@Overridepublic void validate(Object obj) throws ValidationException {String fieldName = getFieldName();Object object = getFieldValue(fieldName, obj);if(object == null)return ;String value = object.toString();if (value == null || value.length() <= 0) return;if(isValidWord(value,11) == true){this.addFieldError(fieldName, obj);}}publicboolean isValidWord(String str1) {boolean isExist = false;if(str1 == "123456")isExist = true;return isExist;}}
配置validators.xml
这个文件要和struts.xml放在同一个目录下，因为启动要加载嘛。
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator Config 1.0//EN" "http://www.opensymphony.com/xwork/xwork-validator-config-1.0.dtd"><validators> <validator name="required" class="com.opensymphony.xwork2.validator.validators.RequiredFieldValidator"/> <validator name="requiredstring" class="com.opensymphony.xwork2.validator.validators.RequiredStringValidator"/> <validator name="int" class="com.opensymphony.xwork2.validator.validators.IntRangeFieldValidator"/> <validator name="long" class="com.opensymphony.xwork2.validator.validators.LongRangeFieldValidator"/> <validator name="short" class="com.opensymphony.xwork2.validator.validators.ShortRangeFieldValidator"/> <validator name="double" class="com.opensymphony.xwork2.validator.validators.DoubleRangeFieldValidator"/> <validator name="date" class="com.opensymphony.xwork2.validator.validators.DateRangeFieldValidator"/> <validator name="expression" class="com.opensymphony.xwork2.validator.validators.ExpressionValidator"/> <validator name="fieldexpression" class="com.opensymphony.xwork2.validator.validators.FieldExpressionValidator"/> <validator name="email" class="com.opensymphony.xwork2.validator.validators.EmailValidator"/> <validator name="url" class="com.opensymphony.xwork2.validator.validators.URLValidator"/> <validator name="visitor" class="com.opensymphony.xwork2.validator.validators.VisitorFieldValidator"/> <validator name="conversion" class="com.opensymphony.xwork2.validator.validators.ConversionErrorFieldValidator"/> <validator name="stringlength" class="com.opensymphony.xwork2.validator.validators.StringLengthFieldValidator"/> <validator name="regex" class="com.opensymphony.xwork2.validator.validators.RegexFieldValidator"/> <validator name="conditionalvisitor" class="com.opensymphony.xwork2.validator.validators.ConditionalVisitorFieldValidator"/> <validator name="badword" class="com.hx.corebase.validtor.BadwordFilter"/></validators>
这样就可以跟struts validator的一样配置了验证了。
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.dtd"><validators><field name="badword"><field-validator type="requiredstring"><message >请输入昵称</message></field-validator><field-validator type="badword"><message >存在过滤词</message></field-validator> </field> </validators>
