springboot hibernate @Valid不生效以及javax.validation.ValidationException: HV000032问题处理

在java项目中写bean校验的时候太麻烦就用hibernate-validator来校验，遇到了两个问题记录一下

## @Valid不生效 ##

在springboot中配置Validator

import org.hibernate.validator.HibernateValidator;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import javax.validation.Validation;
    import javax.validation.Validator;
    import javax.validation.ValidatorFactory;
    
    @Configuration
    public class ValidatorConfiguration { 
        @Bean
        public Validator validator() { 
            ValidatorFactory validatorFactory = Validation.byProvider(HibernateValidator.class)
                    .configure()
                    .addProperty("hibernate.validator.fail_fast", "true")
                    .buildValidatorFactory();
            return validatorFactory.getValidator();
        }
    }

## 一个报错 javax.validation.ValidationException: HV000032: Unable to initialize org.hibernate.validator.internal.constraintvalidators.bv.size.SizeValidatorForCharSequence. ##

导致这个问题有很多原因，一个是没有引入`javax.el-api`，另一个是`属性配置`问题引起的

最终pom中关于hibernate校验的依赖，请检测是否都引入了

<dependency>
                <groupId>org.hibernate.validator</groupId>
                <artifactId>hibernate-validator</artifactId>
                <version>6.0.13.Final</version>
            </dependency>
            <dependency>
                <groupId>javax.validation</groupId>
                <artifactId>validation-api</artifactId>
                <version>2.0.1.Final</version>
            </dependency>
            <dependency>
                <groupId>javax.el</groupId>
                <artifactId>javax.el-api</artifactId>
                <version>3.0.0</version>
            </dependency>

一个错误的属性配置

@Size(min = 10, max = 6, message = "验证码长度应该在4-6位之间")

如果min比max大就会引起

javax.validation.ValidationException: HV000032: Unable to initialize org.hibernate.validator.internal.constraintvalidators.bv.size.SizeValidatorForCharSequence.

一个测试示例

@Size(min = 4, max = 6, message = "验证码长度应该在4-6位之间")
        @NotNull(message = "验证码不能为空")
        private String validateCode;
    
        @Max(value = 100, message = "数字最大值为20")
        @Min(value = 20, message = "数字最小值为20")
        @NotNull(message = "数字不能为空")
        private Long number;

改完pom记得在pom文件上右键Maven->Reimport
