shiro的拦截器执行过程

找到当前的request对应的过滤器链

internalDoFilter:193, ApplicationFilterChain (org.apache.catalina.core) [6]
doFilter:125, OncePerRequestFilter (org.apache.shiro.web.servlet)
doFilterInternal:362, AbstractShiroFilter (org.apache.shiro.web.servlet)
AbstractShiroFilter.executeChain
AbstractShiroFilter.getExecutionChain
DefaultFilterChainManager.proxy
NamedFilterList.proxy
SimpleNamedFilterList.proxy
ProxiedFilterChain.doFilter
AbstractShiroFilter.getExecutionChain
AbstractShiroFilter.executeChain

判断过滤器是否能够被启用

FilterChain.doFilter
ProxiedFilterChain.doFilter
OncePerRequestFilter.doFilter
OncePerRequestFilter.doFilterInternal

做URL匹配

AdviceFilter.doFilterInternal
AdviceFilter.preHandle
PathMatchingFilter.preHandle
    PathMatchingFilter.pathsMatch:124
    PathMatchingFilter.pathsMatch:141
    AntPathMatcher.matches  做URL匹配
    
PathMatchingFilter.isFilterChainContinued

AnonymousFilter.onPreHandle：匿名拦截器，通过静态资源

AccessControlFilter.onPreHandle -> isAccessAllowed() || onAccessDenied()
AuthenticationFilter.isAccessAllowed:判断用户是否在线

AdviceFilter.doFilterInternal  匹配完成
AdviceFilter.executeChain 

这是进入方法转发到Controller的过程

ProxiedFilterChain.doFilter
ApplicationFilterChain.doFilter 
ApplicationFilterChain.internalDoFilter
WsFilter.doFilter 
ApplicationFilterChain.doFilter 
FrameworkServlet.service

这个是完整的调用链条
