Shiro入门 1. 什么是shiro shiro是apache的一个开源框架，是一个权限管理的框架，实现 用户认证、用户授权。 spring中有spring security (原名Acegi)，是一个权限框架，它和spring依赖过于紧密，没有shiro使用简单。 shiro不依赖于spring，shiro不仅可以实现 web应用的权限管理，还可以实现c/s系统， 分布式系统权限管理，shiro属于轻量框架，越来越多企业项目开始使用shiro。 2. 在应用程序角度来观察如何使用Shiro完成工作(图01) Subject：主体，代表了当前“用户”，这个用户不一定是一个具体的人，与当前应用交互的任何东西都是Subject，如网络爬虫，机器人等；即一个抽象概念；所有Subject 都绑定到SecurityManager，与Subject的所有交互都会委托给SecurityManager；可以把Subject认为是一个门面；SecurityManager才是实际的执行者； SecurityManager：安全管理器；即所有与安全有关的操作都会与SecurityManager 交互；且它管理着所有Subject；可以看出它是Shiro 的核心，它负责与后边介绍的其他组件进行交互，如果学习过SpringMVC，你可以把它看成DispatcherServlet前端控制器； Realm：域

I have been trying to figure out how to use Realm with SwiftUI. The problem is that SwiftUI and Realm both have a List type. When you import SwiftUI into your Realm model to make the class a BindableObject and try to create a Realm List property there is an error. Is it possible to use an instance of the Realm object model and make it a BindableObject in SwiftUI? Sure, it's very simple, use the module identifier as prefix like this : let members = RealmSwift.List<Member>() Now to the second part of your question. It's easy to encapsulate a Realm object (or list, or resultset) in an

shiro异步请求返回JSON响应 需求1：当shiro请求资源，但是没有进行认证时，默认是进行重定向，现在需要返回JSON响应。注意异步请求，服务器重定向后，ajax拿到的是浏览器重定向后的到的页面源码。 解决2: 自定义FormAuthenticationFilter。覆盖onAccessDenied方法。返回JSON字符串。并将自定义的过滤器添加到ShiroFilterFactoryBean，键的名称为authc。 需求2：ShiroFilterFactoryBean用注解时，过滤的urls被写死在代码中，需要将urls的配置放到配置文件中。 解决2： 方法1:ShiroFilterFactoryBean不使用注解方法，而是xml配置注入。@ImportResource("classpath:shiro/shiro-config.xml") 方法2:自己通过shiro的Ini类加载ini配置文件。读取自定义的urls。 步骤 自定义 authc 对应过滤器 FormAuthenticationFilter。覆盖 onAccessDenied 方法返回JSON响应。 将自定义过滤器添加到 ShiroFilterFactoryBean。名称为 authc 。 ResultFormAuthenticationFilter package com.mozq.shiro.shiro01

I'm understand that <security-role><role-name>Admin</role-name></security-role> is for container map it with tomcat-users.xml (realm) but I confuse about if I didn't use realm but I use database how container know which field in my database is for role-name or it have naming convention in database field name like "role_name" and container will know it Thank you for every advices Just use a database realm and configure the table and column names in a <Realm> element in server configuration file. For Tomcat, this is described in the Realm HOWTO . Here's an extract of relevance, from the
