解决方案

1、首先查看一下web.xml与shiro配置文件中bean的id是否一致 （xml中没问题）

2、查看web.xml配置文件是否加载shiro的配置文件(spring-shiro-web.xml)（配置加载文件没问题）

3、这种情况下，基本上可以确定启动Web项目加载配置文件时出现问题，加载顺序或者没有加载到项目中，基于IDEA情况：

• File > Project Structure > Modules > 找到项目对应模块
• Source 视图（ 看到右侧树中没有加载resource配置文件目录 ）
• 在左侧项目找到resource目录，点击Resource （Mark as : Resource ）
• 右侧树中就会出现对应路径
• 点击 Apply + OK 保存

---

本次出现的错误是因为spring-shiro的配置文件没有被加载到spring上下文中所导致。
