1、web.xml文件的配置
所有javaweb项目第一步要做的就是对web.xml文件进行配置。

<?xml version="1.0" encoding="UTF-8"?>

2、spring-mvc.xml文件的配置
这个文件主要是对springmvc的相关配置。

<?xml version="1.0" encoding="UTF-8"?>

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd">

<!-- 它背后注册了很多用于解析注解的处理器,其中就包括context:annotation-config/配置的注解所使用的处理器 -->

<!-- 所以配置了之后,便无需再配置context:annotation-config -->

<!-- 启用SpringMVC的注解功能,它会自动注册HandlerMapping、HandlerAdapter、ExceptionResolver的相关实例 -->  
<mvc:annotation-driven/>  

<!-- 配置SpringMVC的视图解析器 -->  
<!-- 其viewClass属性的默认值就是org.springframework.web.servlet.view.JstlView -->  
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
    <property name="prefix" value="/"/>  
    <property name="suffix" value=".jsp"/>  
</bean>  

<!-- 默认访问跳转到登录页面(即定义无需Controller的url<->view直接映射) -->  
<mvc:view-controller path="/" view-name="forward:/login.jsp"/>  

<!-- 由于web.xml中设置是:由SpringMVC拦截所有请求,于是在读取静态资源文件的时候就会受到影响(说白了就是读不到) -->  
<!-- 经过下面的配置,该标签的作用就是:所有页面中引用"/js/**"的资源,都会从"/resources/js/"里面进行查找 -->  
<!-- 我们可以访问http://IP:8080/xxx/js/my.css和http://IP:8080/xxx/resources/js/my.css对比出来 -->  
<mvc:resources mapping="/js/**" location="/resources/js/"/>  
<mvc:resources mapping="/css/**" location="/resources/css/"/>  
<mvc:resources mapping="/WEB-INF/**" location="/WEB-INF/"/>  

<!-- SpringMVC在超出上传文件限制时,会抛出org.springframework.web.multipart.MaxUploadSizeExceededException -->  
<!-- 该异常是SpringMVC在检查上传的文件信息时抛出来的,而且此时还没有进入到Controller方法中 -->  
<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">  
    <property name="exceptionMappings">  
        <props>  
            <!-- 遇到MaxUploadSizeExceededException异常时,自动跳转到/WEB-INF/error_fileupload.jsp页面 -->  
            <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">WEB-INF/error_fileupload</prop>  
            <!-- 处理其它异常(包括Controller抛出的) -->

        </props>  
    </property>  
</bean>  

3、spring-context-shiro.xml文件配置
这个文件是对shiro权限框架的配置。

<?xml version="1.0" encoding="UTF-8"?>
xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

<!-- 继承自AuthorizingRealm的自定义Realm,即指定Shiro验证用户登录的类为自定义的ShiroDbRealm.java -->

<!-- 定义缓存管理器 --> 


<!-- session的失效时长,单位毫秒 -->

<!-- 删除失效的session -->

<!-- Shiro默认会使用Servlet容器的Session,可通过sessionMode属性来指定使用Shiro原生Session -->  
<!-- 即<property name="sessionMode" value="native"/>,详细说明见官方文档 -->  
<!-- 这里主要是设置自定义的单Realm应用,若有多个Realm,可使用'realms'属性代替 -->  
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">  
    <property name="realm" ref="myRealm"/>
    <!-- 使用配置的缓存管理器 --> 
 <property name="cacheManager" ref="cacheManager"></property> 
 <!-- 会话管理 -->
 <property name="sessionManager" ref="sessionManager" />

<!-- Shiro主过滤器本身功能十分强大,其强大之处就在于它支持任何基于URL路径表达式的、自定义的过滤器的执行 -->  
<!-- Web应用中,Shiro可控制的Web请求必须经过Shiro主过滤器的拦截,Shiro对基于Spring的Web应用提供了完美的支持 -->  
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">  
    <!-- Shiro的核心安全接口,这个属性是必须的 -->  
    <property name="securityManager" ref="securityManager"/>  
    <!-- 要求登录时的链接(可根据项目的URL进行替换),非必须的属性,默认会自动寻找Web工程根目录下的"/login.jsp"页面 -->  
    <property name="loginUrl" value="/"/>  
    <!-- 登录成功后要跳转的连接(本例中此属性用不到,因为登录成功后的处理逻辑在LoginController里硬编码为main.jsp了) -->  
    <!-- <property name="successUrl" value="/system/main"/> -->  
    <!-- 用户访问未对其授权的资源时,所显示的连接 -->  
    <!-- 若想更明显的测试此属性可以修改它的值,如unauthor.jsp,然后用[玄玉]登录后访问/admin/listUser.jsp就看见浏览器会显示unauthor.jsp -->  
    <property name="unauthorizedUrl" value="/"/>  
    <!-- Shiro连接约束配置,即过滤链的定义 -->  
    <!-- 此处可配合这篇文章来理解各个过滤连的作用http://blog.csdn.net/jadyer/article/details/12172839 -->  
    <!-- 下面value值的第一个'/'代表的路径是相对于HttpServletRequest.getContextPath()的值来的 -->  
    <!-- anon:它对应的过滤器里面是空的,什么都没做,这里.do和.jsp后面的*表示参数,比方说login.jsp?main这种 -->  
    <!-- authc:该过滤器下的页面必须验证后才能访问,它是Shiro内置的一个拦截器org.apache.shiro.web.filter.authc.FormAuthenticationFilter -->  
    <property name="filterChainDefinitions">  
        <value>  
            /mydemo/login=anon  
            /mydemo/getVerifyCodeImage=anon  
            /main**=authc  
            /user/info**=authc  
            /admin/listUser**=authc,perms[admin:manage]  
        </value>  
    </property>  
</bean>  

<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->  
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>  

<!-- 开启Shiro的注解(如@RequiresRoles,@RequiresPermissions),需借助SpringAOP扫描使用Shiro注解的类,并在必要时进行安全逻辑验证 -->  
<!-- 配置以下两个bean即可实现此功能 -->  
<!-- Enable Shiro Annotations for Spring-configured beans. Only run after the lifecycleBeanProcessor has run -->  
<!-- 由于本例中并未使用Shiro注解,故注释掉这两个bean(个人觉得将权限通过注解的方式硬编码在程序中,查看起来不是很方便,没必要使用) -->  
<!--   
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/>

spring+ boot+ shiro+ jwt怎么监听用户是否在线

关于shiro在跨域情况下的验证码存session取不到的问题请教下会shiro的大神们。
(后端springboot整合shiro,前端vue) shiro配置 参考文章 https://blog.csdn.net/qq_34021712/article/details/80470738 在跨域的情况下 (两台机器,前端8080端口访问后台8081端口),后端就写了2个接口验证码接口和登录接口 。 问题描述:请求验证码接口以后把验证码存到shiro的session里面并返给前端页面展示(没问题),问题出在登录的时候,登录接口首先从session里获取验证码为null,我看过session不是同一个,这是怎么回事呢?(当我把前端代码和后端都放在一台机器上运行没有问题) filter拦截验证码请求的response我设置了跨域* 还是没有解决,是否和shiro的配置有关呢?
Spring boot项目,使用IP访问正常,使用域名访问时请求头出现多个JSESSIONID
如题 Spring Boot + shiro + freemarker项目,使用IP访问一切正常,切换为域名访问就出现异常了,导致后台无法正常提取session 如图: ![图片说明](https://img-ask.csdn.net/upload/202001/15/1579089726_304557.png) 第二个sessionid才是系统后台生成的,第一个不知道怎么来的 请大神帮忙!!
单一入口的API接口使用shiro如果进行权限鉴权
在进行数据通讯当中,全部数据都是走 http://host/api/ 这个URL地址,用业务请求码来控制请求返回的结果,每个请求码可能会有多种情况发生,不同的用户角色控制其使用接口的权限,包含一个接口中不同的情况也要控制,在使用Shiro中就方了,大佬们有好的解决方案吗
手机端登录shiro验证问题

Springboot整合Shiro 记住密码(RememberM)之后怎么实现重启浏览器,我的登录信息也不过期?
1. cookie管理对象 ``` @Bean public CookieRememberMeManager cookieRememberMeManager() { CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager(); SimpleCookie simpleCookie = new SimpleCookie("rememberMe"); simpleCookie.setMaxAge(259200000); cookieRememberMeManager.setCookie(simpleCookie); cookieRememberMeManager.setCipherKey(Base64.decode("6Zm+6I2j5Y+R5aS+5ZOlAA==")); return cookieRememberMeManager; } ``` 2. 上面可以实现cookie保存,重启浏览器,无需登录;但是我发现,cookie虽在, 如我重启之后,ajax调用getRequest().getSession().getAttribute("userName") 这个时候发现Session已经不存在。会报java.lang.NullPointerException空指针异常。在网上找了博客,有些有人说关闭浏览器cookie都也释放了,但是我上面确实也能实现关闭重启之后无需登录,只要不获取session。在程序里面不获取session不可能的。 * 哪位大佬能给点解释?怎么才能实现关闭浏览器session也不过期? 记住密码之后,关闭浏览器,重启电脑再次打开也无需登录? ## **解决办法:** ``` /** * cookie对象; * @return */ @Bean public SimpleCookie rememberMeCookie(){ // 这个参数是cookie的名称,对应前端的checkbox的name = rememberMe SimpleCookie simpleCookie = new SimpleCookie("rememberMe"); // cookie生效时间30天,单位秒; simpleCookie.setMaxAge(2592000); // 浏览器中通过document.cookie可以获取cookie属性,设置了HttpOnly=true,在脚本中就不能的到cookie,可以避免cookie被盗用 simpleCookie.setHttpOnly(true); // JSESSIONID的path为/用于多个系统共享JSESSIONID simpleCookie.setPath("/"); return simpleCookie; } /** * cookie管理对象;记住我功能 * @return */ @Bean public CookieRememberMeManager rememberMeManager(){ CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager(); cookieRememberMeManager.setCookie(rememberMeCookie()); // rememberMe cookie加密的密钥 建议每个项目都不一样 默认AES算法 密钥长度(128 256 512 位) cookieRememberMeManager.setCipherKey(Base64.decode("2A2V+RFLUs+eTA3Kpr+dag==")); return cookieRememberMeManager; } /** * 自定义过滤器 * @author : fyk * @create : 2019/11/14 16:12 **/ @Bean public CustomUserFilter customUserFilter() { CustomUserFilter customUserFilter = new CustomUserFilter(); return customUserFilter; } ``` ``` package com.cocosum.blog.core.shiro.filter; import com.cocosum.blog.commons.utils.SysConstant; import com.cocosum.blog.system.entity.UserInfo; import lombok.extern.slf4j.Slf4j; import org.apache.shiro.subject.Subject; import org.apache.shiro.web.filter.AccessControlFilter; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpSession; import java.util.Objects; /** * 自定义过滤器 * @author : fyk * @create : 2019/11/14 17:06 **/ @Slf4j public class CustomUserFilter extends AccessControlFilter { @Override protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception { Subject subject = getSubject(request, response); if (subject == null) { return false; } // 转成HttpSession对象 HttpSession session = ((HttpServletRequest) request).getSession(); // 获取当前登录用户(获取用户) Object userName = session.getAttribute(SysConstant.UserConstant.USER_NAME); // 如果因为session过时或者浏览器关闭,导致保存的登录信息随着session的关闭而清空了 if (Objects.isNull(userName)) { // 获取主体信息, session被清空之后,主体信息不会被清除掉 UserInfo userInfo = (UserInfo) subject.getPrincipal(); if (Objects.nonNull(userInfo)) { session.setAttribute(SysConstant.UserConstant.USER_NAME, userInfo.getUserName()); } else { // 否则session与主体信息都为空,那就说明没有登录。则需要重新登录 } } return true; } @Override protected boolean isAccessAllowed(ServletRequest servletRequest, ServletResponse servletResponse, Object o) throws Exception { return true; } @Override protected boolean onAccessDenied(ServletRequest servletRequest, ServletResponse servletResponse) throws Exception { return true; } } ```
