回答: 当出现"This application has no explicit mapping for /error, so you are seeing this as a fallback."的错误时,通常是因为Spring Boot应用程序没有为指定的URL路径设置显式的映射。这意味着应用程序无法找到与该URL路径匹配的控制器方法或处理程序。为了解决这个问题,你可以尝试以下几个步骤:
1. 确保你的控制器类中有一个映射到该URL路径的方法。例如,你可以在控制器类中添加一个@RequestMapping注解来映射到该URL路径,如下所示:
@RequestMapping("/your-url-path")
public String yourControllerMethod() {
// your code here
}
2. 确保你的URL路径与你在控制器类中定义的映射路径完全匹配。包括大小写和斜杠的使用。
3. 检查你的应用程序的配置文件,确保没有其他配置或拦截器导致了该错误。
4. 如果你使用的是JSP页面,确保你的JSP文件位于正确的位置,并且在控制器方法中返回正确的视图名称。
希望这些步骤能够帮助你解决该错误。如果问题仍然存在,请提供更多的代码和配置信息,以便我们能够更好地帮助你解决问题。\[1\]\[2\]\[3\]
