下面这个变红

import org.hibernate.validator.constraints.Length;
import javax.validation.constraints.*;

添加下面这个依赖

<!-- https://mvnrepository.com/artifact/org.hibernate.validator/hibernate-validator -->
<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.2.0.Final</version>
</dependency>

或者使用springboot的validator

    <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-validation</artifactId>
            
        </dependency>
