那些遇到过的问题

java.lang.IllegalArgumentException：无法解析参数号：电话

2 java annotations constraints spring-mvc

由于我使用 @phone 注释作为验证器，它引发了一些异常作为非法参数。有任何线索吗？如何在这个即时消息中使用 @Ajay 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;
            }

            }

这是我的自定义注释类。此代码是我从互联网上获取的，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。阿杰注释：

            package com.dineshonjava.validator;
             import java.lang.annotation.Documented;
            import java.lang.annotation.Retention;

            @Target( { ElementType.METHOD, ElementType.FIELD })
            @Retention(RetentionPolicy.RUNTIME)
            public @interface Ajay {
                 String message() default "{Phone}";

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

这是我的验证器类，我在这里编写了用于验证我的电话号码的编码，在这里我为 @Ajay 注释进行了自定义验证，我在这个验证器类中进行了验证。阿杰验证器：

            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()-/.]*");

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。
