问题
I'm developing a web application in which I have to use Shiro Apache for users and roles management.
I'm cofiguring web.xml file and I got the next error when I try to run the server.
SEVERE: Exception starting filter ShiroFilter error

I read that this issue is probably caused by a blank shiro.ini file, isn't it? But the problem is that my file is not a blank file. Here is my web.xml file
web.xml:

Because it doesn't work, when I try to use it, I got a File Not Found error and I don't know if it is due to a bad classpath definition.
I have the next classpath:
回答1:
My shiro.ini file was:
# =============================================================================
# Tutorial INI configuration
#
# Usernames/passwords are based on the classic Mel Brooks' film "Spaceballs" :)
# =============================================================================
[main]
sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager
securityManager.sessionManager = $sessionManager
# -----------------------------------------------------------------------------
# Users and their (optional) assigned roles
# username = password, role1, role2, ..., roleN
# -----------------------------------------------------------------------------
[users]
user = 1234,gestor
user2 = 1234,editor
# -----------------------------------------------------------------------------
# Roles with assigned permissions
# roleName = perm1, perm2, ..., permN
# -----------------------------------------------------------------------------
[roles]
profesor = *
gestor = *
I fixed the issue by adding:
filterChainResolver = org.apache.shiro.web.filter.mgt.PathMatchingFilterChainResolver
In the main part of my shiro.ini file.
