IDEA  -->File -->Project Structure->Project Settings-->Libraries

发现和build.gradle中版本不一致（上图是处理好后的截图，已经一致了）。

项目用的是1.5.11，而上图原本显示的是1.8.7。

然后右键删除此Library，然后重新利用gradle去build一次项目，重新下载出一致的版本。

导致问题的原因：

git拉下来代码之后，新的代码新增Redis相关代码，但是gradle没有编译，导致相关代码报错。

alt+enter提示导入data-redis相关包，直接通过这里导入了data-redis,导致和springboot其他包版本不一致从而出现诡异问题。
