【解决】SpringMVC整合Shiro之 Error creating bean with name 'shiroFilter' defined in class path resource...

完整的部分错误日志：

错误分析：

整合shiro之前程序正常启动，但是整合完之后出现问题，原因就是在项目启动加载web.xml的时候，<context-param>的执行顺序是在<servlet>之前的，但是呢，加载注入UserRealm的时候，再次注入UserService就会出现注入失败的情况，原因就是开启注解，扫描包的配置写在spring_mvc.xml中，也就是说我们在访问一个我们还没有注入到Spring容器的bean。所以出现异常。

解决办法是在加载shiro配置文件之前或者之中配置扫描包和开启自动注解。

对应的spring_mvc_shiro.xml文件中加入：

<mvc:annotation-driven />
<!-- 扫描的包 -->
<context:component-scan base-package="com.guide.*.service,com.guide.*.mapper" />
