如何解决与java.lang.ClassNotFoundException相关的问题：Spring Boot 2.1.3中的org.springframework.boot.bind.RelaxedPropertyResolver

Question

我一直在使用下面提到的站点的指导来开发社交登录系统： http://littlebigextra.com/part-1-authorising-user-using-spring-social-google-facebook-and-linkedin-and-spring-security/

我已经做了一切作为指导。但是，当我尝试构建项目时出现错误： java.lang.ClassNotFoundException：org.springframework.boot.bind.RelaxedPropertyResolver

Soneone可以帮助您在春季靴子中解决此问题（2.1.3。释放）

我的pom.xml文件如下：
