SpringBoot 整合Shiro实现动态权限加载更新+Session共享+单点登录
作者:sans_
juejin.im/post/5d087d605188256de9779e64
一.说明
shiro是一个安全框架,项目中主要用它做认证,授权,加密,以及用户的会话管理,虽然shiro没有springsecurity功能更丰富,但是它轻量,简单,在项目中通常业务需求shiro也都能胜任.
二.项目环境
-
mybatis-plus版本: 3.1.0
-
springboot版本:2.1.5
-
jdk版本:1.8
-
shiro版本:1.4
-
shiro-redis插件版本:3.1.0
数据表(sql文件在项目中):数据库中测试号的密码进行了加密,密码皆为123456

log-impl: org.apache.ibatis.logging.stdout.stdoutimpl
二.编写项目基础类
用户实体,dao,service等在这里省略,请参考源码
编写exception类来处理shiro权限拦截异常
创建sha256util加密工具
创建spring工具
/**
* @description spring上下文工具类
* @author sans
* @createtime 2019/6/17 13:40
*/
@component
public class springutil implements applicationcontextaware {
private static applicationcontext context;
/**
* spring在bean初始化后会判断是不是applicationcontextaware的子类
* 如果该类是,setapplicationcontext()方法,会将容器中applicationcontext作为参数传入进去
* @author sans
* @createtime 2019/6/17 16:58
*/
@override
public void setapplicationcontext(applicationcontext applicationcontext) throws beansexception {
context = applicationcontext;
}
/**
* 通过name返回指定的bean
* @author sans
* @createtime 2019/6/17 16:03
*/
public static <t> t getbean(class<t> beanclass) {
return context.getbean(beanclass);
}
}
创建shiro工具
/**
* @description shiro工具类
* @author sans
* @createtime 2019/6/15 16:11
*/
public class shiroutils {
/** 私有构造器 **/
private shiroutils(){}
private static redissessiondao redissessiondao = springutil.getbean(redissessiondao.class);
/**
* 获取当前用户session
* @author sans
* @createtime 2019/6/17 17:03
* @return sysuserentity 用户信息
*/
public static session getsession() {
return securityutils.getsubject().getsession();
}
/**
* 用户登出
* @author sans
* @createtime 2019/6/17 17:23
*/
public static void logout() {
securityutils.getsubject().logout();
}
/**
* 获取当前用户信息
* @author sans
* @createtime 2019/6/17 17:03
* @return sysuserentity 用户信息
*/
public static sysuserentity getuserinfo() {
return (sysuserentity) securityutils.getsubject().getprincipal();
}
/**
* 删除用户缓存信息
* @author sans
* @createtime 2019/6/17 13:57
* @param username 用户名称
* @param isremovesession 是否删除session
* @return void
*/
public static void deletecache(string username, boolean isremovesession){
//从缓存中获取session
session session = null;
collection<session> sessions = redissessiondao.getactivesessions();
sysuserentity sysuserentity;
object attribute = null;
for(session sessioninfo : sessions){
//遍历session,找到该用户名称对应的session
attribute = sessioninfo.getattribute(defaultsubjectcontext.principals_session_key);
if (attribute == null) {
continue;
}
sysuserentity = (sysuserentity) ((simpleprincipalcollection) attribute).getprimaryprincipal();
if (sysuserentity == null) {
continue;
}
if (objects.equals(sysuserentity.getusername(), username)) {
session=sessioninfo;
}
}
if (session == null||attribute == null) {
return;
}
//删除session
if (isremovesession) {
redissessiondao.delete(session);
}
//删除cache,在访问受限接口时会重新授权
defaultwebsecuritymanager securitymanager = (defaultwebsecuritymanager) securityutils.getsecuritymanager();
authenticator authc = securitymanager.getauthenticator();
((logoutaware) authc).onlogout((simpleprincipalcollection) attribute);
}
}
创建shiro的sessionid生成器
三.编写shiro核心类
创建realm用于授权和认证
/**
* @description shiro权限匹配和账号密码匹配
* @author sans
* @createtime 2019/6/15 11:27
*/
public class shirorealm extends authorizingrealm {
@autowired
private sysuserservice sysuserservice;
@autowired
private sysroleservice sysroleservice;
@autowired
private sysmenuservice sysmenuservice;
/**
* 授权权限
* 用户进行权限验证时候shiro会去缓存中找,如果查不到数据,会执行这个方法去查权限,并放入缓存中
* @author sans
* @createtime 2019/6/12 11:44
*/
@override
protected authorizationinfo dogetauthorizationinfo(principalcollection principalcollection) {
simpleauthorizationinfo authorizationinfo = new simpleauthorizationinfo();
sysuserentity sysuserentity = (sysuserentity) principalcollection.getprimaryprincipal();
//获取用户id
long userid =sysuserentity.getuserid();
//这里可以进行授权和处理
set<string> rolesset = new hashset<>();
set<string> permsset = new hashset<>();
//查询角色和权限(这里根据业务自行查询)
list<sysroleentity> sysroleentitylist = sysroleservice.selectsysrolebyuserid(userid);
for (sysroleentity sysroleentity:sysroleentitylist) {
rolesset.add(sysroleentity.getrolename());
list<sysmenuentity> sysmenuentitylist = sysmenuservice.selectsysmenubyroleid(sysroleentity.getroleid());
for (sysmenuentity sysmenuentity :sysmenuentitylist) {
permsset.add(sysmenuentity.getperms());
}
}
//将查到的权限和角色分别传入authorizationinfo中
authorizationinfo.setstringpermissions(permsset);
authorizationinfo.setroles(rolesset);
return authorizationinfo;
}
/**
* 身份认证
* @author sans
* @createtime 2019/6/12 12:36
*/
@override
protected authenticationinfo dogetauthenticationinfo(authenticationtoken authenticationtoken) throws authenticationexception {
//获取用户的输入的账号.
string username = (string) authenticationtoken.getprincipal();
//通过username从数据库中查找 user对象,如果找到进行验证
//实际项目中,这里可以根据实际情况做缓存,如果不做,shiro自己也是有时间间隔机制,2分钟内不会重复执行该方法
sysuserentity user = sysuserservice.selectuserbyname(username);
//判断账号是否存在
if (user == null) {
throw new authenticationexception();
}
//判断账号是否被冻结
if (user.getstate()==null||user.getstate().equals("prohibit")){
throw new lockedaccountexception();
}
//进行验证
simpleauthenticationinfo authenticationinfo = new simpleauthenticationinfo(
user, //用户名
user.getpassword(), //密码
bytesource.util.bytes(user.getsalt()), //设置盐值
getname()
);
//验证成功开始踢人(清除缓存和session)
shiroutils.deletecache(username,true);
return authenticationinfo;
}
}
创建sessionmanager类
创建shiroconfig配置类
/**

@configuration
public class shiroconfig {
private final string cache_key = "shiro:cache:";

}

四.实现权限控制
shiro可以用代码或者注解来控制权限,通常我们使用注解控制,不仅简单方便,而且更加灵活.shiro注解一共有五个:
一般情况下我们在项目中做权限控制,使用最多的是requirespermissions和requiresroles,允许存在多个角色和权限,默认逻辑是and,也就是同时拥有这些才可以访问方法,可以在注解中以参数的形式设置成or
示例
使用顺序:shiro注解是存在顺序的,当多个注解在一个方法上的时候,会逐个检查,知道全部通过为止,默认拦截顺序是:requiresroles->requirespermissions->requiresauthentication->
requiresuser->requiresguest
示例
创建userrolecontroller角色拦截测试类
/**
* @description 角色测试

return map;
}

}
创建userlogincontroller登录类
/**

*/
@restcontroller
@requestmapping("/userlogin")
public class userlogincontroller {

map<string,object> map = new hashmap<>();
//进行身份验证
try{
//验证身份和登陆
subject subject = securityutils.getsubject();
usernamepasswordtoken token = new usernamepasswordtoken(sysuserentity.getusername(), sysuserentity.getpassword());
//验证成功进行登录操作
subject.login(token);
}catch (incorrectcredentialsexception e) {

map.put("msg","登录失败,该用户已被冻结");
return map;

map.put("code",500);
map.put("msg","该用户不存在");
return map;
} catch (exception e) {

public map<string,object> unauth(){
map<string,object> map = new hashmap<>();
map.put("code",500);
map.put("msg","未登录");
return map;
}
}
五.postman测试
登录成功后会返回token,因为是单点登录,再次登陆的话会返回新的token,之前redis的token就会失效了
当第一次访问接口后我们可以看到缓存中已经有权限数据了,在次访问接口的时候,shiro会直接去缓存中拿取权限,注意访问接口时候要设置请求头.
admin这个号现在没有sys:info:all这个权限的,所以无法访问getinfoall接口,我们要动态分配权限后,要清掉缓存,在访问接口时候,shiro会去重新执行授权方法,之后再次把权限和角色数据放入缓存中
访问添加权限测试接口,因为是测试,我把增加权限的用户admin写死在里面了,权限添加后,调用工具类清掉缓存,我们可以发现,redis中已经没有缓存了
再次访问getinfoall接口,因为缓存中没有数据,shiro会重新授权查询权限,拦截通过
