所有 Spring-Boot 应用程序始终显示弹出登录

技术标签:
【中文标题】所有 Spring-Boot 应用程序始终显示弹出登录【英文标题】：All Spring-Boot Application always show a popup login 【发布时间】：2018-02-01 11:28:10 【问题描述】：我将 Spring 和 Spring Boot 框架与 Spring Security 一起用于具有简单 UI 的简单登录项目。在我所有的项目中，使用 STS，在启动我的应用程序并运行 localhost 地址没有错误后，我收到一个弹出登录窗口，而不是我的 html 页面。 如果我使用 user 和 默认安全密码，我总是会得到一个 Whitelabel 错误页面作为结果。此外，如果我使用不正确的值，弹出窗口仍然存在，如果我使用默认访问值，我会收到此消息。
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
这是一个简单的项目代码。正如您在项目结构中看到的那样，所有 html 文件都在模板文件夹中。我也尝试在我的 application.properties 文件中使用server.error.whitelabel.enabled=false。`
为什么html界面一直没有显示？

【问题讨论】：
您要的网址是什么？ 查看以下链接中的答案：***.com/questions/31134333/… @AmerQarabsa 我尝试了所有的 url 组合。 localhost:8080/login 应该是初始 url 或者只是 localhost:8080/ @AmitKBist，app.java 的正确位置看起来和我在那个问题中的位置一样！或不？ ***.com/a/39017839/7148194 【参考方案1】：跟进阿里的回答：
@SpringBootApplication 隐含@Configuration、@EnableAutoConfiguration 和@ComponentScan
所以，考虑改变：
@Configuration
@EnableAutoConfiguration
public class SecurityConfig extends WebSecurityConfigurerAdapter
到：
@Component
public class SecurityConfig extends WebSecurityConfigurerAdapter
并在整个包更改中扫描 bean：
@SpringBootApplication
public class SpringbootUiLoginApplication
到：
@SpringBootApplication
@ComponentScan("com.cyberdemon")
public class SpringbootUiLoginApplication
【讨论】：
注释不会让我使用@符号，所以我希望这是有道理的： SpringBootApplication 等于 Configuration EnableAutoConfiguration ComponentScan 那些你不需要两次的注释。所以你可以从 SecurityConfig 中删除它们 你需要 SecurityConfig 是一个 bean，所以添加 @Component 是一种简单的方法来完成它。 ComponentScan 只扫描基础包和子包。如果要保留问题中的项目结构，则需要扫描所有包。我认为 ComponentScan("com.cyberdemon") 会做到这一点。【参考方案2】：你需要重组你的包，使其属于你的 SpringbootUiLoginApplication 的包，或者使用 @ComponentScan 告诉 Spring Boot 在哪里可以找到你的 bean 类。
【讨论】：
确实，所有这些，包括控制器和安全配置都必须属于 com.cyberdemon.springboot 包，因为它是定义您的应用程序的地方。以上是关于所有 Spring-Boot 应用程序始终显示弹出登录的主要内容，如果未能解决你的问题，请参考以下文章
