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

使用hibernate validator出现上面的错误，一般两种情况：

（1）注解与需要校验的数据类型不匹配，然后就会找不到。譬如在String 类型上使用@Min

（2）validation-api和hibernate-validator的版本不匹配。导致注解没有对应的Validator。譬如：validation-api2.x已经收录了@javax.validation.constraints.NotEmpty，但hibernate-validator 5.x中还没有相应的Validator。

hibernate-validator 5.x中是使用组合注解的方式来处理@org.hibernate.validator.constraints.NotEmpty

如下图所示，@javax.validation.constraints.NotEmpty是没有对应的Validator的，如果使用肯定会报 Novalidator

温馨提示：Spring boot 中spring-boot-starter-web 中已经匹配的版本。如果不在pom.xml新增validation-api和hibernate-validator就不会出现版本不匹配

配套的版本：

（1）validation-api 1.1.0.Final + hibernate-validator 5.3.6.Final

如果在基本类型上面用NotEmpty或者NotBlank 会出现上面的错

No validator could be found for constraint ‘javax.validation.constraints.NotBlank‘ validating type

这是因为@NotBlank是validation-api 2.x才有的。hibernate-validator 6.x 依赖的是validation-api 2.x。所以排除项目中hibernate-validator 6.x 以下的依赖。

写实体类时，经常会对域增加校验，例如@NotNull表示哪个字段不能为空，昨天晚上调试代码，就遇到了问题，@Entitypublic class ApplicationCategory implements Serializable { private static final long serialVersionUID = -8018302345969463947L; @Id

经检查，是因为在 Integer 类型的字段上加了@NotBlank的校验注解，而该注解只能用于字符串类型，因此
