java.lang.IllegalArgumentException : can't parse argument number: Phone 异常

Question

因为我使用@phone 注释作为 validator ，所以它上升了一些异常作为非法参数。有什么线索吗？如何使用@Ajay 在此 im 中使用我们自己的注释进行电话验证但它不起作用。请帮助我解决此问题并向我发送用于自定义验证的代码。或者请分享一些链接以了解自定义验证。

这是我的模型类:

            package com.dineshonjava.bean;


            import com.dineshonjava.validator.Ajay;
           @Entity
            @Table(name="employees")
            @SecondaryTable(name="employeedetails")
            public class EmployeeBean {
            @Ajay
            private String phone;


            public String getPhone() {
                return phone;
            }
            public void setPhone(String phone) {
                this.phone = phone;
            }

            }

这是我自定义的注释类。这段代码是我从互联网上获得的，但在我的项目中实现时显示错误。我不知道如何在我的项目中进行自定义验证。阿杰注解:

            package com.dineshonjava.validator;
             import java.lang.annotation.Documented;
            import java.lang.annotation.Retention;
            import java.lang.annotation.Target;
            import java.lang.annotation.ElementType;
            import java.lang.annotation.RetentionPolicy;
           import javax.validation.Constraint;
            import javax.validation.Payload;
            @Documented
            @Constraint(validatedBy = AjayValidator.class)
            @Target( { ElementType.METHOD, ElementType.FIELD })
            @Retention(RetentionPolicy.RUNTIME)
            public @interface Ajay {
                 String message() default "{Phone}";

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

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

            }

这是我的 validator 类，我在这里编写代码来验证我的电话号码，我为 @Ajay 注释做了自定义验证，我在这个 validator 类中进行了验证。Ajay validator :

            package com.dineshonjava.validator;

            import javax.validation.ConstraintValidator;
            import javax.validation.ConstraintValidatorContext;

            public class AjayValidator implements ConstraintValidator<Ajay, String> {

                    @Override
                    public void initialize(Ajay ajay) { 

                    }
                  @Override
            public boolean isValid(String phone, ConstraintValidatorContext cxt) {
                if(phone == null) {
                    return false;
                }
                return phone.matches("[0-9()-/.]*");
            }

            }

Answer 1

您的问题的解决方案就在您的问题中:

java.lang.NumberFormatException: For input string: "Phone"

您尝试将字符串“Phone”解析为数字。当然，这是不可能的，因为它不包含任何数字，而只包含字符。
