javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint,NotBlank判断不能为空

java 验证出现如下错误：

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint
错误原因
Java实体类中属性是Integer类型，用了NotBlank判断不能为空，而这个注解是判断字符串是否为空

3、解决办法

去掉@NotBlank注解、使用@NotNull

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint,NotBlank判断不能为空的相关文章

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint

使用hibernate validator出现上面的错误, 需要注意 @NotNull 和 @NotEmpty 和@NotBlank 区别 @NotEmpty 用在集合类上面@NotBlank 用在String上面@NotNull 用在基本类型上如果在基本类型上面用NotEmpty或者NotBlank 会出现上面的错 http://blog.csdn.net/dracotianlong/article/details/23181729 javax.validation.Unexpec

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint 解决方法

在使用hibernate validator进行参数有效性校验的时候,我们有时候会遇到javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint ,比如,在我们的应用中,使用了自定义注解Dict对枚举进行有效性校验,因为定义的Dict应用于String类型,例如: package com.yidoo.base.metadata.validate; import jav

版本不匹配引发的血案：javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint

发现一个API报了错: javax.validation.UnexpectedTypeException: HV000030: No validator could be found for constraint 'javax.validation.constraints.NotEmpty' validating type 'java.lang.String'. Check configuration for 'cancelReason' at org.hibernate.validator.i

spring boot中使用javax.validation以及org.hibernate.validator校验入参

这里springboot用的版本是:<version>2.1.1.RELEASE</version> 自带了hibernate.validator,所以不用添加额外依赖 1.创建个对应前台form的测试vo,并添加字段校验注解 import java.math.BigDecimal; import java.util.Date; import java.util.List; import javax.validation.constraints.AssertTrue; import

Spring Validation（使用Hibernate Validator）

1.需要的jar包 hibernate-validator.5.1.3.Final.jar validation-api.1.1.0.Final.jar 2.springsevlet-config.xml配置在spring3之后,任何支持JSR303的validator(如Hibernate Validator)都可以通过简单配置引入,只需要在配置xml中加入,这时validatemessage的属性文件默认为classpath下的ValidationMessages.properties:

[javax.validation]验证

package main; import java.util.Set; import javax.validation.ConstraintViolation; import javax.validation.Validation; import javax.validation.Validator; import javax.validation.ValidatorFactory; import javax.validation.constraints.Max; import javax.va

java.lang.NoSuchMethodError：javax.validation.BootstrapConfiguration.getClockProviderClassName

Spring Boot 2随附了hibernate-validator 6(org.hibernate.validator:hibernate-validator:6.0.16.Final依赖于validation-api 2(javax.validation:validation-api:2.0.1.Final),后者特定于Java EE 8,请参见附录F.依赖版本.但是可能必须使用Java支持较旧的应用程序服务器仅限EE 7,Spring Framework 5仍应支持它,请参阅运行时支持.
