为什么后台能登陆进去但是前台登录就会显示This application has no explicit mapping for /error, so you are seeing this as a fallback.

这个问题可能是由于前台和后台的登录逻辑同导致的。后台登录可能使用了正确的映射路径，而前台登录则没有。具体原因可能有以下几种情况：

1. 路径映射问题：前台登录请求的路径没有在应用程序中进行显式的映射，导致找不到对应的处理方法。你可以检查前台登录的路径是否正确，并确保在应用程序中有相应的映射。

2. 权限问题：前台登录可能需要特定的权限才能访问，而后台登录可能具有足够的权限。你可以检查前台登录所需的权限设置，并确保用户具有足够的权限来访问前台登录。

3. 异常处理问题：前台登录可能在处理过程中发生了异常，但没有进行正确的异常处理，导致显示错误信息。你可以检查前台登录的代码，确保在处理过程中进行了适当的异常处理。

this application has no explicit mapping for/error,so you are seeing this as a fallback

"This application has no explicit mapping for /error, so you are seeing this as a fallback"这句话是一个错误信息，表明应用程序中没有为路径"/error"定义映射，因此您看到了这个回退信息。它是一个常见的错误，可能是由于配置问题、路由错误或资源文件缺失等原因导致的。这个错误信息通常出现在Java应用程序中，如Word源码中的Java应用程序，以及Eclipse部署的项目中。您可以检查您的应用程序配置和路由设置，以确保正确地定义了路径映射，从而解决这个错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

error page.

This error message is typically displayed when a web application encounters an error that it cannot handle or does not have a specific error page mapped to. It is a fallback error page that is displayed to users when the application cannot show a more specific error message.

If you are encountering this error message, it may indicate a problem with the application or server. You can try refreshing the page or contacting the website administrator for assistance.
