【问题描述】:
我的 SpringMVC 项目出现此错误。我必须在浏览器中手动添加完整路径才能运行代码,但无法直接运行。

请告诉我如何解决这个问题。
【问题讨论】:
-
你用什么网址来获取页面?
-
定义“完整路径”和“直接运行”。
-
localhost:8080/SpringMVC/student1 ...实际上在运行项目后我得到localhost:8080/SpringMVC/.I必须在URL之后手动添加student1
-
我不想手动定义完整路径
-
显然,因为您独特的 GET 映射控制器方法已映射到
/student1。如果你想在/上显示一些东西,那么你需要一个映射到/的控制器方法
