我正在尝试通过遵循the instructions in this link来学习如何使用Spring Boot和Spring Cloud设置OAuth2，这是大型教程的第5部分。在多次阅读本教程并逐步完成后，我决定只需下载the completed version from github at this link再次学习它。
authserver，resource和ui个应用启动，但当我尝试登录时，授权应用不接受教程中提供的凭据。我希望在分解它并测试小变化的影响之前，让我的devbox上的示例正常工作。
调试日志中指明Spring向视图发送的错误的特定行是：
o.s.security.web.FilterChainProxy :
/login?error reached end of additional filter chain;
proceeding with original chain
需要采取哪些具体步骤才能1.）下载并安装应用程序，以及2.）使用身份验证服务器成功登录？
这是我到目前为止所做的：
在我的CentOS 7 devbox终端上，我输入了：
cd /home/user/spring_boot_apps/
mkdir whole_security_tutorial && cd whole_security_tutorial
git clone https://github.com/spring-guides/tut-spring-security-and-angular-js
cd /home/user/spring_boot_apps/whole_security_tutorial/tut-spring-security-and-angular-js/oauth2/authserver
mvn spring-boot:run
cd /home/user/spring_boot_apps/whole_security_tutorial/tut-spring-security-and-angular-js/oauth2/resource
mvn spring-boot:run
cd /home/user/spring_boot_apps/whole_security_tutorial/tut-spring-security-and-angular-js/oauth2/ui
mvn spring-boot:run
然后，在FireFox中，我键入了http://localhost:8080。这导致加载页面包括预期的主页和登录链接，因此我单击登录链接，该链接重定向到授权应用程序，该应用程序显示登录页面。
我输入acme作为用户名，acmesecret作为密码输入，但身份验证失败并显示消息There was a problem logging in. Please try again.
我做错了什么？
注意：我没有在/home/user/spring_boot_apps/whole_security_tutorial/tut-spring-security-and-angular-js/oauth2启动该应用，因为在之前的尝试中这样做无法访问其他子应用，同时也导致其他应用由于port 9000无法启动已经在使用中的错误。
登录尝试的Spring Boot调试日志如下：
