Spring MVC中的org.springframework.web.servlet.PageNotFound noHandlerFound

Question

当我输入URL“ http://localhost:8090/hamropasal/”时出现错误，因为它说当我点击URL时未找到映射。我已添加了所有依赖项和所需的bean，但无法正常工作。我试图在代码中查找错误，但是我没有发现实际的问题是什么。

org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/hamropasal/] in DispatcherServlet with name 'dispatcher'
