项目中遇到的异常

1、

 

 

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

 

是一个springmvc的验证异常，原因是缺少jar包

 

解决方法

 

 

	<dependency>
		<groupId></groupId>
		<artifactId>validation-api</artifactId>
		<version>1.1.</version>
	</dependency>
	<dependency>
		<groupId></groupId>
		<artifactId>hibernate-validator</artifactId>
		<version>5.2.</version>
	</dependency>

 

 

 

 

 

贴入上边的坐标，就能解决问题。

 

 

:

 

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。
