springboot 2.0 集成 shiro 和 thymeleaf-extras-shiro 2.0 使用过程遇到的问题

用法就不写了,百度一搜一堆.

1.首先 如果使用springboot2.*, 则必须使用 thymeleaf-extras-shiro 2.0及以上(目前作者还没有更新更高版本).
2.遇到的问题
在页面中使用自定义权限标签add:mypermission

<a shiro:hasPermission="add:mypermission" class="">添加a>

如果前端页面加了两个或者以上的权限标签,而登录用户只有一个或者没有此权限,则会报错.
原因: 后台 UserRealm 类的 AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) 方法中
权限获取(SimpleAuthorizationInfo info)存在空值 “”

解决办法:
解决办法,在增加权限的后台加入判空处理即

   try {//不确定是什么原因导致权限可能会生成一个空值"", 会报错,所以将空值删除if (info != null && info.getStringPermissions() != null) {Set<String> permissions = info.getStringPermissions();for (String permission : permissions) {if (StringUtils.isEmpty(permission)) {permissions.remove(permission);}}}} catch (Exception e) {System.out.println("移除空值权限出错---"+e.getMessage());}

最后附完整错误
