在 spring 集成 shiro 的我的项目时，启动我的项目产生了异样：

解决方案
1、首先查看一下 web.xml 与 shiro 配置文件中 bean 的 id 是否统一（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、这种状况下，基本上能够确定启动 Web 我的项目加载配置文件时呈现问题，加载程序或者没有加载到我的项目中，基于 IDEA 状况：
- File > Project Structure > Modules > 找到我的项目对应模块
- Source 视图（看到右侧树中没有加载 resource 配置文件目录）
- 在左侧我的项目找到 resource 目录，点击 Resource（Mark as : Resource）
- 右侧树中就会呈现对应门路
- 点击 Apply + OK 保留
本次呈现的谬误是因为 spring-shiro 的配置文件没有被加载到 spring 上下文中所导致。
