spring 集成 shiro框架时，报出这个异常
这类异常NoSuchBeanDefinitionException，配置文件中bean加载异常。

严重: Exception starting filter shiroFilter

web.xml

加载配置文件配置

<context-param>
	<param-name>contextConfigLocation</param-name>
    <param-value>classpath*:spring-*.xml</param-value>
</context-param>
<listener>
	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

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
修改前

修改后

确定后重新启动就正常了，感谢原作者。
