【Shiro】Unsatisfied dependency expressed through method 'securityManager' parameter 3
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
大家好，我是烤鴨：
? ? ? 采坑記錄，springboot 整合 shiro。
? ? ? 環境：
? ? ? ?springboot? ??2.0.5.RELEASE
? ? ? ?shiro-spring? ? 1.4.0
? ? ? ?shiro-redis? ? 3.1.0
1.問題
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
? ? 按異常信息去百度查結果，效果不理想。同事本地試過是沒有問題的，合代碼的時候出現了問題。爭取少改動代碼解決問題。
?? ?發現不太好改，找不到問題在哪。
? ? 代碼重現。主要是
? ? ShiroConfig.java

源頭：
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 沒注入，所以用到的地方會報錯。
用到的地方是 securityManager(ShiroRealm shiroRealm, SessionManager sessionManager, RememberMeManager rememberMeManager, RedisCacheManager cacheManager) 構造方法的第三個參數
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。
問題找到就好解決了。
改寫構造方法。改后的shiroConfig.java如下。
遇到問題時，沒有搜索到特別好的解決方式時。
并沒有根據報錯信息仔細查找問題源頭（主要也是因為看不懂），應該優先分析報錯信息，這樣會解決的比較快。
