解释一下 This application has no explicit mapping for /error, so you are seeing this as a fallback.

这个应用程序没有针对 /error 的显式映射,因此您正在看到它作为一个后备选项。
这意味着当用户请求了一个未定义的页面或路径时,应用程序无法找到一个明确的错误处理程序,并且将返回一个默认的错误页面或消息。这种情况下,应用程序会使用一个默认的错误处理程序,例如 Spring Boot 提供的出错处理机制,以显示一个错误页面或者给出一条错误消息。

这个错误提示"This application has no explicit mapping for /error, so you are seeing this as a fallback."表示应用程序没有对"/error"路径进行显式的映射,所以你才看到这个错误。解决这个问题的方法有两种。首先,你需要检查配置文件application是否与你的项目文件在同一级目录下。其次,你需要确保控制该页面的controller和控制页面跳转的controller的@RequestMapping后面的地址是否与该页面一致。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

springboot This application has no explicit mapping for /error, so you are seeing this as a fallback.
根据引用内容,出现这个错误的原因有几种可能性。首先,可能是由于在配置文件中没有正确配置视图解析器的问题。如果使用的是较高版本的spring-boot-starter-parent,应该使用spring.mvc.view.prefix和spring.mvc.view.suffix进行配置。如果使用的是较低版本的spring-boot-starter-parent,应该使用spring.view.prefix和spring.view.suffix进行配置。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
