基于mybatisPlus的特殊字符校验

要实现以下代码前提是导入Mybatis-plus的jar:

* @author WENGKAIBO505
 */
@Target({ElementType.FIELD, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy=SpecialFieldValidator.class)
public @interface SpecialField {

    String message() default "不能包含特殊字符";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};

 

 

ackage com.paic.ocss.gateway.model.validator;

import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

/**
 * @author WENGKAIBO505
 */
public class SpecialFieldValidator implements ConstraintValidator<SpecialField, String> {


    /**

     * 特殊字符的正则表达式

    */

   private String reg = "[_`~!@#$%^&*()+=|{}':;',\\\\[\\\\].<>/?~！@#￥%……&*（）——+|{}【】‘；：”“’。，、？]|\\n|\\r|\\t";

   private Pattern pt = Pattern.compile(reg);

   @Override

   public void initialize(SpecialField specialField) {

      // TODO
    Auto-generated method stub

   }

@Override

public boolean isValid(String value, ConstraintValidatorContext arg1) {

      if (value == null) {
         return true;

      }

      Matcher m = pt.matcher(value);

      if (m.find()) {

         return false;
      }

      return true;

   }

}
