项目升级到springboot2.3之后，参数校验的注解报错，发现spring-boot-starter-web的依赖项已经去除了依赖
点开spring-boot-starter-web源码看了下。

没有发现 hibernate-validator
原版本如下：
<dependency> <groupId>org.hibernate.validator</groupId> <artifactId>hibernate-validator</artifactId> <version>6.0.17.Final</version> <scope>compile</scope> </dependency>
刚看了一下官方文档。需要手动引入
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-validation</artifactId> </dependency>
