本文详细介绍了从零开始将Shiro与Spring进行整合的步骤，包括项目构建、依赖配置、配置文件设置、过滤器使用，以及涉及的工厂类、处理器和 Realm 的创建。通过实践理解Shiro的认证和授权流程。

一、新建maven项目,坐标如下,打包方式为war

<groupId>zh.shiro.spring</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.0-SNAPSHOT</version>

依赖的parent工程为zh-root

<parent>
        <groupId>zh.root</groupId>
        <artifactId>zh-root</artifactId>
        <version>1.0-SNAPSHOT</version>
</parent>

二、在pom.xml中添加依赖的jar包

该demo只是做一个简单的整合,不用去查数据库,所以就不依赖jdbc相关的jar包了,只需要添加日志相关的jar包,spring相关的jar包,和Shiro相关的jar包,版本都是最新的就可以,可以去maven的中央仓库查看。

 <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>
        <!--日志-->
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </dependency>

        <!--shiro-->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-ehcache</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
        </dependency>
        <!--spring-->

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
        </dependency>

        <!--<dependency>-->
        <!--<groupId>org.springframework</groupId>-->
        <!--<artifactId>spring-jdbc</artifactId>-->
        <!--</dependency>-->

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
        </dependency>
    </dependencies>

三、在src/resources下添加配置文件

Spring配置文件:applicationContext.xml
Shiro缓存的配置文件:ehcache.xml
日志的配置文件:log4j.properties
servlet的配置文件:spring-servlet.xml

四、配置webapp/WEB-INF路径下的web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
    <!--spring配置:加载配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--springmvc的配置-->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!--1. 配置shiro的shiroFilter-->
    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        <init-param>
            <param-name>targetFilterLifecycle</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>shiroFilter</f
