大家好，我是烤鸭：

      采坑记录，springboot 整合 shiro。

      环境：

       springboot    2.0.5.RELEASE

       shiro-spring    1.4.0

       shiro-redis    3.1.0

1.问题

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'shiroFilter' defined in class path resource [com/test/shiro/ShiroConfig.class]: Unsatisfied dependency expressed through method 'shiroFilter' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name'securityManager' defined in class path resource [com/test/shiro/ShiroConfig.class]: Unsatisfied dependency expressed through method 'securityManager' parameter 3; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.crazycake.shiro.RedisCacheManager' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

2.原因

    按异常信息去百度查结果，效果不理想。同事本地试过是没有问题的，合代码的时候出现了问题。争取少改动代码解决问题。
    发现不太好改，找不到问题在哪。

    代码重现。主要是

    ShiroConfig.java

}

根据报错信息和上面的代码找问题。异常都是从下往上看的。
源头：
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.crazycake.shiro.RedisCacheManager' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

RedisCacheManager 没注入，所以用到的地方会报错。
用到的地方是 securityManager(ShiroRealm shiroRealm, SessionManager sessionManager, RememberMeManager rememberMeManager, RedisCacheManager cacheManager) 构造方法的第三个参数
nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityManager' defined in class path resource [com/test/shiro/ShiroConfig.class]: Unsatisfied dependency expressed through method 'securityManager' parameter 3。
问题找到就好解决了。
改写构造方法。改后的shiroConfig.java如下。

遇到问题时，没有搜索到特别好的解决方式时。
并没有根据报错信息仔细查找问题源头（主要也是因为看不懂），应该优先分析报错信息，这样会解决的比较快。
