SpringBoot与Shiro整合权限管理实战 作者 ： Stanley 罗昊 【 转载请注明出处和署名，谢谢！ 】 *观看本文章需要有一定SpringBoot整合经验* Shiro框架简介 Apache Shiro是一个强大且易用的Java安全框架，执行身份验证、授权、密码学和会话管理。使用Shiro的易于理解的API，可以快速、轻松地获得任何应用程序， 从最小的移动应用程序到最大的网络和企业应用程序。 分析Shiro的核心API 其实，Shiro的核心类有三个，分别是： 1.Subject：这个类呢，我们称之当前用户的主体，这个用户的主体包含了登陆、注销等等的一些方法，还有一些判断授权的一些方法； 2.SecurityManager：这个名称翻译过来就是，安全管理器的意思； 3.Realm：这个Realm呢其实我们Shiro去链接数据库的一个桥梁，因为，我们的程序需要去操作数据库去获取一些用户的信息，这些操作都需要Realm去完成； 这个三个API呢，都存在一些关系，比如.SecurityManager是需要去关联我们的Realm，Subject是需要把操作交给我们的SecurityManager，总结下来就是，Subject是需要去管理我们的SecurityManager，而SecurityManager去关联我们的Realm；

shiro配置流程 web.xml中配置shiro的filter spring中配置shiro的过滤器工厂，指定对不同地址权限控制 ， 传入安全管理器 配置安全管理器，传入realm，realm中定义具体授权和认证的流程 配置自定义凭证匹配器，指定token和info的匹配方式。 权限访问的配置 定义所有的权限的String集合 在自定义realm中重写doGetAuthoriaztionInfo（）,创建所有权限的String集合， 创建SimpleAuthorizationInfo的对象，调用addStringPermission,添加权限的集合，返回该对象 控制访问指定资源时所需要的权限 a. 用代码校验。 //拿到当前的subject Subject subject = SecurityUtils.getSubject(); //检查是否具有指定权限 subject.checkPermission("部门管理"); b. 在过滤器工厂中配置拦截地址 /system/user/list.do = perms["部门管理"] /system/user/list.do = authc,roles[用户管理] c. 注解实现 @RequiresPermissions("用户管理") 使用shiro标签对视图渲染进行控制 <shiro:hasPermission name="用户管理

It is easy to use Realm with classes by inheriting from Object . But how would I save a struct containing several fields to realm in Swift? E.g. struct DataModel { var id = 0 var test = "test" } I know the documentation is clear about supported types. But maybe there is nice workaround or - even better - someone from realm could write about future plans about structs. To save a struct in Realm, means copying the data into a Realm Object . The reason why Realm Objects are classes and not structs is because they are not inert values, but auto-updating objects that represent the persisted data in

I'm trying to compare Realm with Snappydb ( This is my repo for those who would like to have a look at benchmark). I guess my way is wrong, as store-to-db time takes super long time in Realm in compare with Sanppydb. Benchmark shows following result. As you can see in the image, Realm is around 100-200 times slower than Snappydb. What I'm doing is creating 10,000 objects first and then storing them into the db. So, in my code I store a Booking object in this way (there is a for loop that iterates 10,000 times): public void storeBooking(final Booking booking) { mRealm.executeTransaction(new

I have the choice of doing a migration, but I would prefer to delete everything in my defaultRealm(). How can I do this easily? realm.deleteObject(object) is the only function along with .deleteObjects. I have tried the following code: Method 1 realm.deleteObjects(RLMObject.objectsInRealm(realm, withPredicate: NSPredicate(value: true))) Method 2 realm.deleteObjects(Dog.allObjectsInRealm(realm)) realm.deleteObjects(Person.allObjectsInRealm(realm)) realm.deleteObjects(Goal.allObjectsInRealm(realm)) realm.deleteObjects(Goals.allObjectsInRealm(realm)) Both fail to prevent the migration exception.

I want remove all message object from realm those are equal to userid RealmQuery<Message> rowQuery = realm.where(Message.class).equalTo(Message.USER_ID, userId); realm.beginTransaction(); //TODO : here I want to remove all messages where userId is equal to "9789273498708475" realm.commitTransaction(); Christian Melchior In 0.88.3 and below you can do: realm.executeTransaction(new Realm.Transaction() { @Override public void execute(Realm realm) { RealmResults<Message> rows = realm.where(Message.class).equalTo(Message.USER_ID,userId).findAll(); rows.clear(); } }); From 0.89 (next release) this
