org.springframework.web.servlet.DispatcherServlet.noHandlerFound No mapping for GET

这个错误提示是Spring MVC框架的DispatcherServlet在处理请求时发生的。它表示没有找到与请求URL匹配的处理器（Controller）。

出现这个错误的原因有很多种可能，比如：

1. 没有在Controller类上添加@RequestMapping注解或者@RequestMapping注解中的value值与请求URL不匹配。

2. 缺少Controller类或者Controller类没有被正确扫描到。

3. 请求的URL中参数错误，比如参数名或参数类型不匹配。

4. 没有配置正确的视图解析器，导致无法找到正确的视图。

解决这个问题需要仔细检查以上几个方面，找到错误的原因并进行修复。
