shiro集成springMVC报错One or more Filters failed to start.
报错信息：
严重: One or more Filters failed to start. Full details will be found in the appropriate container log file
一月 31, 2020 5:45:46 下午 org.apache.catalina.core.StandardContext startInternal
严重: Context [/edaily-web] startup failed due to previous errors
一月 31, 2020 5:45:46 下午 org.springframework.web.context.support.XmlWebApplicationContext doClose查看idea自带的tomcat日志文件：
可以看到错误信息：（基本意思是shiroFilter里面没有signout的过滤条件，需要增加）
严重: Exception starting filter shiroFilter
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'shiroFilter': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: There is no filter with name 'signout' to apply to chain [/api/logout] in the pool of available Filters. Ensure a filter with that name/path has first been registered with the addFilter method(s).

... 64 more 原因是我在shiroFilter中的filterChainDefinitions配置了signout的动作，但springMVC中我并没有写signout的过滤拦截，如@RequestMapping（“/signout”），而spring上下文启动的时候会去检查这些filter，所以报这个错。暂时注释掉 就可以了。
