这么多人都是 TL;DS

[night98]

重新导包试一下，信息太少无法排查。

[adli007]

@night98 导了，也显示导成功了，还是没用

[night98]

@adli007 #3 把.m2 中有关 springboot 的文件夹都删了重新下一下试试

[adli007]

@night98 还是不行

[wenzhoou]

你只要把上面的 stack trace 重新排版一下就有不少人帮你。这个不排版拿手机真没法看啊。

[mringg]

ClassNotFoundException: org.springframework.http.client.support.BasicAuthorizationInterceptor
如果异常信息全，那么是这触发的

[adli007]

@wenzhoou 现在改不了，追加又超字了...当时没考虑好

[adli007]

@mringg 不知道这是什么错，我还是重新搭建一个吧

[xuuuu]

自己创建个 bean 把这个对象 new 出来返回

[neuliuxi]

: No active profile set, falling back to default profiles: 有可能是这个问题吗

[maxiaofeng]

看到楼上的这句，，‘: No active profile set, falling back to default profiles:’
我推测是：没有加载到 远程 git 配置中心的配置文件。
