由于我使用@phone注释作为验证器，因此它上升了 一些例外作为非法论据。任何线索？如何使用@Ajay进行手机验证，但是它不能正常使用我自己的注释。请帮我解决这个问题并发送代码进行自定义验证。或者请分享一些链接以了解自定义验证。
这是我的模特课：
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。这个代码我从互联网上得到它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。 Ajay注释：
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，我在这里编写了验证我的电话号码的代码。我为@Ajay注释做了定制验证，我在此验证器类中进行了验证。 Ajay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()-/.]*");
}
}

答案 0 :(得分：4)
您问题的解决方案正好在您的问题中：
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，只包含字符。
答案 1 :(得分：0)
公共类LCAppConfig实现WebMvcConfigurer {
@Bean
public InternalResourceViewResolver viewResolverBean() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource=new ResourceBundleMessageSource();
messageSource.setBasename("external");
return messageSource;
}
@Bean
public LocalValidatorFactoryBean validator() {
LocalValidatorFactoryBean localValidatorFactoryBean=new LocalValidatorFactoryBean();
localValidatorFactoryBean.setValidationMessageSource(messageSource());
return localValidatorFactoryBean;
}
@Override
public void addFormatters(FormatterRegistry registry) {
registry.addFormatter(new PhoneNumberFormatter());
}
@Override
public Validator getValidator() {
return validator();
}
} enter code here
您必须定义一个coustom验证器，并告诉spring使用该特定文件
在这里我定义了一个 messageSource（），该返回
定位属性文件（在我的情况下是“ external.properties”）。 之后，我们必须使用 LocalValidatorFactoryBean 类注册此 messageSource（）方法，并最终通过覆盖 WebMvcConfigurer 接口的getValidator方法来注册验证器方法，这是我们在课堂上实现的。
