请求的资源不适用于tomcat8 deploy
[英]The requested resource is not available with tomcat8 deploy
问题描述
每次我收到消息“请求的资源不可用”。 我在Spring框架中创建了一个Maven项目。 它的构建成功，但是当我想执行tomcate7或tomcate8时，给出了同样的错误。 Java版本是1.8。 它愚蠢的示例代码，我不知道为什么我收到这个错误。
这是代码片段：

我认为您的tomcat没问题，对我有用：
1.-在项目上单击鼠标右键->属性->部署程序集->添加-> Java构建路径条目-> Maven依赖关系
2.-在您的MvcConfiguration中， @ComponentScan MvcConfiguration的basePackages必须是com.exp.aqua.controller 。
3.-在index.jsp移除href属性中的.jsp扩展名： <a href="home">
最后，请记住， index.jsp必须位于WebContent文件夹中，而home.jsp必须位于views 。
Tomcat 7请求的资源不可用
