我在尝试使用 Spring Framework 时遇到了很多麻烦，并且不知道错误在哪里。我正在使用 Tomcat 7.0.68 部署应用程序。
当我尝试使用 URL ( http://localhost:8080/fj21-spring/olaMundo) 时，我收到了 404 错误，但它应该被映射为在我的 Controller 类上调用我的 Action 方法，如下所示:
package com.caelum.tarefas.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class TarefasController {
@RequestMapping("/olaMundo")
public String execute(){
return "ok";
}
}
我的 pom.xml 文件如下:

谢谢!
编辑
将我在 Controller 类上的注释更改为 @RequestMapping(value="/olaMundo") 后，Tomcat 在控制台上写入一个堆栈跟踪，如下所示(也许我之前也错过了这个堆栈跟踪):

最佳答案
看起来您部署的应用程序找不到 spring 库 enter link description here
希望这个问题能帮到你
关于java - Spring MVC 应用程序不适用于 Tomcat 和 Eclipse，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36252794/
