Question

我是 java Spring 的初学者我尝试创建简单的 hello world 应用程序，当我运行它给我这个错误这是我的错误消息我尝试了一切我可以。
我已经更改了 url-pattern 但是当我将文件保存在 web-inf 文件夹下时它不会起作用。

我遇到了一个异常，根本原因如下：

我的控制器

 package com.dare.controller.home;
 import org.springframework.stereotype.Controller; 
 import org.springframework.web.bind.annotation.RequestMapping;

 @Controller public class controller {
   @RequestMapping("/home")
   public String home(){
         return "home";
      } 
 }

堆栈跟踪表明没有 cacheManager。您需要通过将此添加到您的 spring xml 配置来告诉 spring 初始化 cacheManager。

<cache:annotation-driven/>

有关详细信息，请参阅 https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/cache/annotation/EnableCaching.html。
