## 集成 Spring ##

1.  pom.xml 添加shiro相关的依赖

> 我使用的版本是 `${version.shiro}` —> 1.3.2

<dependency>
                <groupId>org.apache.shiro</groupId>
                <artifactId>shiro-core</artifactId>
                <version>${version.shiro}</version>
            </dependency>
            <dependency>
                <groupId>org.apache.shiro</groupId>
                <artifactId>shiro-web</artifactId>
                <version>${version.shiro}</version>
            </dependency>
            <dependency>
                <groupId>org.apache.shiro</groupId>
                <artifactId>shiro-aspectj</artifactId>
                <version>${version.shiro}</version>
            </dependency>
            <dependency>
                <groupId>org.apache.shiro</groupId>
                <artifactId>shiro-ehcache</artifactId>
                <version>${version.shiro}</version>
            </dependency>
            <dependency>
                <groupId>org.apache.shiro</groupId>
                <artifactId>shiro-spring</artifactId>
                <version>${version.shiro}</version>
            </dependency>

1.  在 web.xml 中作如下配置：
    
        
        
            <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</filter-name>
                <url-pattern>/*</url-pattern>
            </filter-mapping>
2.  在`spring`配置文件中添加如下配置
    
    一般都是新建一个配置文件，比如博主这里是新建一个 `applicationContext-shiro.xml`
    
        <?xml version="1.0" encoding="UTF-8"?>
        <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
        
        
            
            
            
            
            
            
        
            
            <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
                <property name="cacheManager" ref="cacheManager"/>
                
                
                <property name="realm" ref="jdbcRealm"/>
            </bean>
        
        
            
            <bean id="sessionManager" class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager">
                <property name="sessionIdCookieEnabled" value="true"/>
                <property name="sessionIdCookie" ref="sessionIdCookie"/>
            </bean>
            <bean id="sessionIdCookie" class="org.apache.shiro.web.servlet.SimpleCookie">
                <constructor-arg name="name" value="jeesite.session.id"/>
            </bean>
        
        
            
            <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
                <property name="cacheManagerConfigFile" value="classpath:ehcache.xml"/>
            </bean>
        
            
            <bean id="jdbcRealm" class="cn.hyc.shiro.realm.ShiroRealm"/>
        
        
            
            <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
        
            
            <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/>
            <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
                <property name="securityManager" ref="securityManager"/>
            </bean>
        
        
            
            <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
                <property name="securityManager" ref="securityManager"/>
                
                <property name="loginUrl" value="/login.jsp"/>
                <property name="successUrl" value="/index.jsp"/>
                <property name="unauthorizedUrl" value="/unauthorized.jsp"/>
        
                
                <property name="filterChainDefinitions">
                    <value>
                        /login.jsp = anon
                        /index.jsp = authc
                        / = authc
                        /** = authc
                        /logout = logout
                    </value>
                </property>
            </bean>
        
        
        </beans>

--------------------

## 集成中的坑 ##

1.  每次启动项目， `ehcache` 都去访问官网，检验是否更新，在 `<ehcache>` 里面添加如下配置即可；
    
        <ehcache name="ehcache" updateCheck="false">
2.  启动报错 `org.apache.shiro.session.UnknownSessionException: There is no session with id`
    
    这是cookie 名字冲突导致的；做如下更改：
    
        
        <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
            <property name="cacheManager" ref="cacheManager"/>
            
            
            <property name="realm" ref="jdbcRealm"/>
        </bean>
    
    自定义 `cookie` 的名字：
    
        
            <bean id="sessionManager" class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager">
                <property name="sessionIdCookieEnabled" value="true"/>
                <property name="sessionIdCookie" ref="sessionIdCookie"/>
            </bean>
            <bean id="sessionIdCookie" class="org.apache.shiro.web.servlet.SimpleCookie">
                <constructor-arg name="name" value="jeesite.session.id"/>
            </bean>

## shiroFilter 的工作原理 ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_100_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lvdW5neW91dGg_size_60_color_AAAAAA_t_70]

`shiroFilter` 是一个拦截器，浏览器的任何访问都会被拦截到；

其中 `loginUrl` 是入口，在配置文件中进行配置；

--------------------

## 权限配置细节 ##

在上面配置 `shiroFilter` 的时候，使用了如下配置：

注意写出后缀名：

<property name="filterChainDefinitions">
                <value>
                    /logout.action = logout
                    /index.jsp = anon
                    /shiro/isAllowLogin.action = anon
                    / = authc
                    /** = authc
                </value>
            </property>

**其具体规则如下：**
