严重：异常启动过滤器ShiroFilter错误

Question

我正在开发一个Web应用程序，其中必须使用Shiro Apache进行用户和角色管理。

我正在配置web.xml文件，尝试运行服务器时遇到下一个错误。

我读到这个问题可能是由空白的shiro.ini文件引起的，不是吗？但是问题是我的文件不是空白文件。这是我的web.xml文件

web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">

    <dispatcher>ERROR</dispatcher>

</web-app>

我没有使用：

<context-param>
        <param-name>shiroConfigLocations</param-name>
        <param-value>WebContent/WEB-INF/shiro.ini</param-value>
</context-param>

因为它不起作用，当我尝试使用它时，出现了“找不到文件”错误，并且我不知道它是否是由于错误的类路径定义引起的。

我有下一个类路径：

Answer 1

我的shiro.ini文件是：

# =============================================================================
# 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 = *

我通过添加以下内容解决了该问题：

filterChainResolver = org.apache.shiro.web.filter.mgt.PathMatchingFilterChainResolver

在我的shiro.ini文件的主要部分。
