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

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
/**

public static void deleteCache(String username, boolean isRemoveSession){
//从缓存中获取Session
Session session = null;
Collection<Session> sessions = redisSessionDAO.getActiveSessions();

}
}
if (session == null||attribute == null) {

}
//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

*/
@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) {

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;
}
/**

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")){

}
//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

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UserLoginController登录类

//进行身份验证
try{
//验证身份和登陆

UsernamePasswordToken token = new UsernamePasswordToken(sysUserEntity.getUsername(), sysUserEntity.getPassword());
//验证成功进行登录操作

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
