感谢您的帮助！

开始=>

我看来像您遇到Maven的腐败罐时的问题它下载它们。我会尝试清除你的Maven缓存，以便它再次下载 –

答

您也需要明确指定一个Bean验证：

@Bean 
public Validator validator(){ 
    return new org.springframework.validation.beanvalidation.LocalValidatorFactoryBean(); 
}

或添加到您的pom.xml：

<dependency> 
    <groupId>com.fasterxml</groupId> 
    <artifactId>classmate</artifactId> 
    <version>0.8.0</version> 
</dependency>
