簡單來說就是在專案所依賴的spring-beans中找不到ObjectProvider類，這個問題是由於版本太低造成的，從Spring 4.3版本以後才有這個類。
此專案遇到這個問題的解決方案，升級spring-boot-starter-parent的版本，從1.3.x升級到1.4.x即可
請看下面截圖
專案中使用的spring-boot-starter-parent的版本是1.3.3.RELEASE,該版本所依賴的spring-beans版本是4.2.5.REALESE，再看spring-beans的原始碼，如下圖
可以看到，4.3以上版本中可以找到ObjectProvider,再看原始碼中的註釋如下
所以，解決此問題只需要更改spring-boot-starter-parent的版本號即可，將版本從1.3.x升級到1.4.x即可
