问题 I'm trying to convert my json data to a .realm file, i think i'm succeeding since i see the default.realm file increasing size but when i try to open it using realm studio i get this error: I'm not sure what to do at this point. The realm/realm mongodb realm sync names are very confusing and links to docs go from one product to another which makes it a lot more confusing. 回答1: Realm is in the process of a change from Realm to MongoDB Realm The first, I call 'classic' Realm. That's going be be

问题 Upon initial load of the app, the Bundled Realm (Realm1) is copied to the documents folder. Now that the bundled realm is set as the default realm, I am able update the bool property so that the table view can show marked and unmarked cells. However I am looking for a way to bundle a second realm (Realm2) with a later update, that will add new data to the existing default realm, but without overwriting the current default realm. I am currently working in swift 5 and Xcode 11.1, if that is

Shiro入门学习与实战（一）

由 强颜欢笑 提交于 2021-02-12 09:56:39
一、概述 1、Shiro是什么？ 　　Apache Shiro是java 的一个安全框架，主要提供：认证、授权、加密、会话管理、与Web集成、缓存等功能，其不依赖于Spring即可使用； 　　Spring Security（Oauth2）也是一个开源的权限框架，但其依赖于Spring运行，功能相对强大；而Shiro相对独立，不依赖于Spring，使用简单、灵活，所以我选择Shiro学习。哈哈~ 2、Shiro基本功能 ①Authentication（音标： [ɔːˌθentɪˈkeɪʃn] ） 　　身份认证，验证用户是不是拥有相应的身份。 ②Authorization（音标：[ˌɔːθərəˈzeɪʃn]） 　　授权即权限验证，验证某个已认证的用户是否拥有某个权限（比如接下来我要实现的：不用用户拥有不用的菜单树） ③Session Management 　　会话管理，在用户登录后，退出之前，所有信息都存在于会话中（这里可以用于sso单点登录） ④Crptography 　　加密，保护数据的安全性（比如密码加密存储到数据库，而不是明文存储） ⑤Web支持 　　非常容易集成到Web环境 ⑥Caching 　　缓存，比如用户登录后，其用户信息、拥有的角色/权限不必每次去查，这样可以提高效率 ⑦Concurrency 　　Shiro支持多线程应用宝并发验证，（即在一个线程中开启另一个线程
