Spring boot with authentication - login page not found (404)
提问by Daniel Pinkpank
I have a problem with my spring application since I've tried to include some security things.
我的 spring 应用程序有问题，因为我试图包含一些安全内容。
After building a small working app including angularJS I followed this spring security tutorialbut I can't get it started. When I try to access any part of the app, the security modul wants to redirect to http://localhost:8080/login... but can't find it.
在构建了一个包括 angularJS 的小型工作应用程序后，我遵循了这个spring 安全教程，但我无法开始。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。
There was an unexpected error (type=Not Found, status=404). No message available
出现意外错误（类型=未找到，状态=404）。没有可用的消息
Maybe I'm just missing a small thing but I can't figure out what it is ^^
也许我只是错过了一件小事，但我不知道它是什么^^

I followed my own hint in the comment above and figured out I forgot extends WebMvcConfigurerAdapterat my Application.class
我在上面的评论中遵循了我自己的提示，发现我忘记extends WebMvcConfigurerAdapter了我的Application.class
That solved the Problem!
这解决了问题！

Where is your login.htmllocated? Can you get to /logindirectly in a browser? I suspect you don't have your ViewResolverset up properly. If you can't go directly to /login, that's your problem. Look at application.properties values spring.view.prefixand spring.view.suffix.
你在哪里login.html？可以/login直接在浏览器中访问吗？我怀疑你没有ViewResolver正确设置。如果你不能直接去/login，那是你的问题。查看 application.properties 值spring.view.prefix和spring.view.suffix.
If you canget there directly, you might be dealing with a hidden error. Spring Boot includes an AutoConfiguration that swallows exceptions and throws a 404. You might want to exclude it (change @EnableAutoConfigurationto @EnableAutoConfiguration(exclude=ErrorMvcAutoConfiguration.class). That will enable you to see any errors that are thrown during the request processing.
如果您可以直接到达那里，那么您可能正在处理一个隐藏的错误。Spring Boot 包含一个 AutoConfiguration，它会吞下异常并抛出 404。您可能想要排除它（更改@EnableAutoConfiguration为@EnableAutoConfiguration(exclude=ErrorMvcAutoConfiguration.class)。这将使您能够看到在请求处理期间抛出的任何错误。
