Spring ConstraintValidator问题上的自动连线密码编码器_Spring_Spring Mvc_Spring Security_Bean Validation

Spring ConstraintValidator问题上的自动连线密码编码器

spring spring-mvc spring-security

Spring ConstraintValidator问题上的自动连线密码编码器,spring,spring-mvc,spring-security,bean-validation,Spring,Spring Mvc,Spring Security,Bean Validation,我已经创建了一个特定的约束来验证指定的密码是否与当前经过身份验证的用户的密码匹配其定义如下： @Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER, TYPE_USE}) @Retention(RUNTIME) @Constraint(validatedBy = CurrentUserPasswordValidator.class) @Documented public @interface UserCurrentPas

我已经创建了一个特定的约束来验证指定的密码是否与当前经过身份验证的用户的密码匹配

其定义如下：

@Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER, TYPE_USE})
@Retention(RUNTIME)
@Constraint(validatedBy = CurrentUserPasswordValidator.class)
@Documented
public @interface UserCurrentPassword {
    String message() default "{constraints.current.password}";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}

 @NotBlank(message="{user.current.pass.notnull}", groups={ UserChangePassword.class })
 @UserCurrentPassword(message="{user.current.pass.not.match}", groups={ UserChangePassword.class })
 @Transient
 private String currentClearPassword;

在验证器中，我需要注入应用程序中使用的密码编码器。定义如下：

import javax.validation.ConstraintValidator; import javax.validation.ConstraintValidatorContext; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.security.core.context.SecurityContextHolder; import org.springframework.security.crypto.password.PasswordEncoder; import persistence.models.User; /** * @author sergio */ public class CurrentUserPasswordValidator implements ConstraintValidator<UserCurrentPassword, String> { private static Logger logger = LoggerFactory.getLogger(CurrentUserPasswordValidator.class); @Autowired private PasswordEncoder passwordEncoder; @Override public void initialize(UserCurrentPassword constraintAnnotation) {} @Override public boolean isValid(String password, ConstraintValidatorContext context) { User user = (User)SecurityContextHolder.getContext().getAuthentication().getPrincipal(); if(user != null){ logger.info(user.toString()); return passwordEncoder.encode(password) == user.getPassword(); } return false; } }
此配置包含在更高级别中：

@Configuration @Import(value = { DataSourceConfig.class, VendorAdapterConfig.class, BeanValidationConfiguration.class }) @EnableJpaRepositories(repositoryFactoryBeanClass = DataTablesRepositoryFactoryBean.class, basePackages = "persistence.repositories") @ComponentScan(value = "persistence.populator" ) public class PersistenceConfig {
问题是，我在运行时得到一个NullPointerException
密码编码器。编码（密码）
我在调试模式下查看了所有消息，没有发现问题。我把它们留在这里：

我希望有人能帮助我。
哪里创建了
CurrentUserPasswordValidator
bean？我认为没有必要，SpringValidatorFactory会处理它。在我看到的其他示例中，不要将ConstraintValidator创建为bean。等等，我收回最后一条语句。注销密码并确认其不为空。BCrypt的第80行是
返回BCrypt.hashpw（rawPassword.toString（），salt）如果密码为空，您将获得帮助Leon的ExceptionTanks。我的@InitBinder配置错误，currentClearPassword始终为空。我认为问题在于它没有注入密码编码器。 2017-01-03 15:04:31 DEBUG DefaultListableBeanFactory:448 -
