带身份验证的Spring启动 - 找不到登录页面(404)

Question

带身份验证的Spring启动 - 找不到登录页面(404)

Dan*_*ank 8 java spring spring-mvc spring-security spring-boot

我的弹簧应用程序有问题,因为我试图包含一些安全性的东西.

在构建一个包含angularJS的小型工作应用程序后,我遵循了这个春季安全教程,但我无法启动它.当我尝试访问应用程序的任何部分时,安全模块想要重定向到http:// localhost:8080/login ...但找不到它.

出现意外错误(type = Not Found,status = 404).没有可用的消息

也许我只是错过了一件小事,但我无法弄清楚它是什么^^

这是我的代码......

我在上面的评论中遵循了自己的暗示,发现我忘extends WebMvcConfigurerAdapter了我的Application.class

这解决了问题!
