【问题描述】：
创建我的休息控制器后，我在邮递员中对其进行测试，并在我的 Eclipse 控制台中收到此警告 org.springframework.web.servlet.DispatcherServlet noHandlerFound “在名称为'springmvc'的 DispatcherServlet 中找不到带有 URI [/Project/MyController/1] 的 HTTP 请求的映射”

【问题讨论】：
-
您正在访问一个在您的控制器中没有任何映射的 URL。请分享控制器代码。
-
@MinarMahmud 我在问题中添加了控制器。
-
我认为您正在尝试调用 searchById。在这种情况下，点击此 URL
/books/1 -
我解决了问题。我扫描了错误的控制器包。
-
太棒了！请添加答案并将其标记为已接受！编码愉快！
