Spring boot 报Add an implement,such as Hibernate Validator, to the classpath_add an implementation, such as hibernate validator-优快云博客

本文解决了一个关于SpringBoot 1.4.7版本启动时报错的问题，具体为BeanValidation API在类路径上但未找到实现。通过分析发现是Hibernate Validator的加载问题，并给出了具体的排查及解决步骤。

spring boot 版本1.4.7.RELEASE
1.启动报错如下：
ationConfigEmbeddedWebAp ationConfigEmbeddedWebAp o. s. b. d. LoggingFai1ureAn APPLICATION FAILED TO START Description : The Bean Validation API is on the classpath but no implementation could be found Action : Add an implementation, such as Hibernate Validator, to the classpeth
2.报错分析
Hibernate Validator的加载问题，查看maven库Hibernate-validator-5.2.5.final.jar存在;
执行mvn clean,mvn install.
工程构建失败，提示如下：
