java - Spring MVC 自定义验证显示错误代码 HV000074。

Question

我正在尝试在 Spring Boot 中实现自定义密码匹配验证。但我收到如下错误:-

PasswordMatch包含Constraint注释，但不包含消息参数

我正在关注此链接 https://www.baeldung.com/registration-with-spring-mvc-and-spring-security用于自定义验证。问题是我收到这样的错误。

javax.validation.ConstraintDefinitionException: HV000074: com.bikram.booking.validation.PasswordMatch 包含 Constraint 注释，但不包含消息参数。 在 org.hibernate.validator.internal.metadata.core.ConstraintHelper.assertMessageParameterExists(ConstraintHelper.java:915)

我在网上搜索了解决方案，但找不到合适的解决方案。

我的模态是

package com.bikram.booking.dto;

import com.bikram.booking.validation.PasswordMatch;
import com.bikram.booking.validation.ValidEmail;

import javax.validation.constraints.*;

@PasswordMatch
public class UserDto {
 @NotNull
    @Size(min = 6, message = "Password should be more than 6 characters")
    @NotEmpty(message = "Please provide a password")
    private String password;


    @NotNull
    @Size(min = 6, message = "Password should be more than 6 characters")
    private String confirmPassword;
}

我的界面是

package com.bikram.booking.validation;

import javax.validation.Constraint;
import javax.validation.Payload;
import java.lang.annotation.Documented;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;

import static java.lang.annotation.ElementType.ANNOTATION_TYPE;
import static java.lang.annotation.ElementType.TYPE;
import static java.lang.annotation.RetentionPolicy.RUNTIME;

@Target({ TYPE, ANNOTATION_TYPE})
@Retention(RUNTIME)
@Constraint(validatedBy = PasswordMatchValidator.class)
@Documented
public @interface PasswordMatch {
    String messages() default "Sorry, passwords does not match";

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

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

实现是

package com.bikram.booking.validation;

import com.bikram.booking.dto.UserDto;
import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;

public class PasswordMatchValidator implements ConstraintValidator<PasswordMatch, Object> {
    @Override
    public void initialize(PasswordMatch constraintAnnotation) {

    }

    @Override
    public boolean isValid(Object obj, ConstraintValidatorContext constraintValidatorContext) {
        UserDto userDto = (UserDto) obj;
        return true;
    }
}

任何提示都将非常值得赞赏。

在PasswordMatch中将messages()重命名为message():

public @interface PasswordMatch {
    String message() default "Sorry, passwords does not match";
    ....
}
