我使用Spring和Spring Boot框架与Spring Security简单的登录项目与简单的用户界面。在我所有的项目中,使用STS,在启动我的应用程序并运行localhost地址后没有错误,我收到一个弹出的登录窗口,而不是我的html页面。如果我使用用户和默认的安全密码,我总是得到一个白色标签错误页作为结果。此外,如果我使用不正确的值,弹出窗口仍然存在,如果我使用默认的访问值,我会得到这条消息。
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
下面是一个简单的项目代码。正如您在项目结构中看到的,所有html文件都位于模板文件夹中。我还尝试使用服务器。错误白标签。在我的应用程序中,enabled=false
。属性文件`
为什么html界面从未显示过?

跟进阿里的回答:
@SpringBootApplication意味着@Configuration、@EnableAutoConfiguration和@ComponentScan
所以,考虑改变:
@Configuration
@EnableAutoConfiguration
public class SecurityConfig extends WebSecurityConfigurerAdapter
致:
@Component
public class SecurityConfig extends WebSecurityConfigurerAdapter
并扫描整个包裹更改中的bean:
@SpringBootApplication
public class SpringbootUiLoginApplication
致:
@SpringBootApplication
@ComponentScan("com.cyberdemon")
public class SpringbootUiLoginApplication
您需要重新构造您的包,使其属于SpringbootUiLoginApplication的包,或者使用@ComponentScan告诉SpringBoot在哪里可以找到bean类。
我知道APIG中有一个设置自定义域名的选项,并且在做了一些研究之后,APIG在后台设置了一个Cloudfront发行版,但由于我不是设置DNS服务的人,也没有权限在aws上更改此特定角色/区域的这些设置,我想知道问题是否在于自定义url没有通过APIG的选项设置?
如果fcm消息包含“通知”部分,而应用程序在后台,则通知传递到系统托盘和数据中的附加意图。 问题是,我无法更改该通知的重要性,而且它们总是不显示弹出窗口。我为API26+修复了这个问题,我添加了通知通道 但对于API25-我找不到解决方案。一个建议是删除“notification”部分,只保留“data”,这将允许fcm将消息传递到 当应用程序在后台/前台,我将能够显示我的自定义通知。
我有一个应用程序,可以让用户设置特定时间期限的任务。一旦过了最后期限,我希望应用程序在所有内容上显示一个视图(请求用户更新任务)。 我的问题是:-如何在当前活动的所有其他活动上显示我的应用程序的视图-如何在用户更新任务之前保持活动在顶部? 使用系统警报窗口这样的东西看起来合理吗?
问题内容: 这个问题已经有了答案,但是我仍然不确定它是如何工作的。 我在footer.php中使用以下HTML: 和以下Javascript: 一切都很好,但是我只想对每个用户显示一次弹出窗口(也许使用所有论坛帖子都使用的cookie内容),但是我不知道确切如何将其合并到上面的JS中。 我知道我将必须在此页脚中加载cookie JS: 但这就是我的全部理解,有人能告诉我添加了Cookie的东西后J
