我正在尝试使用spring boot和JPA实现一个服务器。

validation-api似乎不在您的需要范围内。将此添加到maven依赖项中：

<!-- https://mvnrepository.com/artifact/javax.validation/validation-api -->
<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.0.Final</version>
</dependency>

如果您正在使用gradle，请添加以下内容：

// https://mvnrepository.com/artifact/javax.validation/validation-api
compile group: 'javax.validation', name: 'validation-api', version: '2.0.0.Final'
