项目中遇到的异常

1、javax.validation.ValidationException

javax.validation.ValidationException: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

javax.validation.ValidationException是一个springmvc的验证异常，原因是缺少jar包

解决方法

<dependency><groupId>javax.validation</groupId><artifactId>validation-api</artifactId><version>1.1.0.Final</version></dependency><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-validator</artifactId><version>5.2.4.Final</version></dependency>

贴入上边的坐标，就能解决问题。

org.springframework.beans.factory.BeanCreationException:

这是spring框架创建实体类失败的时候产生的异常，根据异常信息往下读，

找到service层创建实体类的时候失败。

发现service的实现类上没有@service注解。
