springboot:shiro
第一次学习系统学习shiro 并将shiro集成到springboot中
参考了很多同学的文章 这里表示非常感谢
demo东拼西凑 基本想实现的东西都凑齐了 实现了
===========================================
本demo是基于前后端分离的形式写的demo 基于api 没有页面 请不要思考页面在哪
本demo主要包括:
1.基于filter md5 加盐登陆(用户名密码写死 自己修改测试)
2.用户角色roles控制 权限perms控制
3.基于redis的session分布式 基于redis的cache分布式(redis亲测 没有问题)
注：含有ehcache 但整体基于redis 所以将网上所有使用ehcache的demo改成redis形式
4.验证码(写死的验证码 自己修改测试)
5.登陆尝试次数限制(自己修改时间测试 注意expiretime单位是秒)
6.session管理(外加一个kitout 未成功 仅做参考)
7.用户修改密码 修改权限 切换用户(非切换角色)
===========================================
readme.md
===========================================
1.用户登陆 通过拦截器MyFormAuthenticationFilter处理
访问地址http://localhost:8080/adminlogin
2.用户登陆成功之后 再次访问/adminlogin地址 会直接访问TestController:submitLogin方法
3.用户退出
访问地址http://localhost:8080/adminlogout
4.MyRoleAuthorizationFilter控制角色
可修改MyShiroRealm中的doGetAuthorizationInfo
String role = "admin"; 改为guest或abc等
5.MyPermAuthorizationFilter控制权限
6.MyAccessControlFilter自定义拦截器 配置在/** 表示全部拦截
7.有权限地址http://localhost:8080/admin/manage
无权限地址http://localhost:8080/admin/test
8.切换用户(注:是切换用户 不是 切换角色) 登陆后访问 http://localhost:8080/switchuser
切换指定账户后 要将账户登录名传递过去 这时在MyShiroRealm中的doGetAuthorizationInfo方法
会获取用户名重新加载传递的用户名的权限
9.修改密码 admin/manage/modifypass
修改密码后要重新登陆
10.修改权限 admin/manage/modifyauth
修改完权限 会调用MyShiroRealm中的doGetAuthorizationInfo方法 重新加载权限
11.session对话管理SessionController
12.用户密码加盐(随机字符串) 加密 需要在用户设置密码的时候处理 并把盐入库存储
用户在登陆的时候 会调用MyShiroRealm中的doGetAuthenticationInfo方法
在方法中将盐查出 传递 进行授权验证
13.cache包下是处理分布式session和cache的 使用的是redis
14.MyModularRealmAuthenticator自定义ModularRealmAuthenticator 处理多realms
15.RetryLimitCredentialsMatcher 匹配器处理登陆尝试次数
16.由于使用了redis做分布式 ehcache-shiro.xml未使用到
