错误原因：是因为我们在使用javax.validation的时候，还需要一个javax.validation的实现包，因为validation只是一个协议，可以使用hibernate-validator这个实现包，完整的使用如下：
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
</dependency>
