Shiro Note +Shiro integration Springboot implementation of login interception, user login authentication, integration of Mybatis

This is the 22nd day of my participation in the August Wen Challenge.More challenges in August

Shiro profileShiro is what? Apache Shiro is a Java security (permissions) framework Shiro can easily develop good enough applications that can be used not only in Javase environment but also in Javaee environment Shiro can complete, authentication, authorization, encryption, session management, Web integration, Cache, etc.

●Authentication: identity Authentication, login, verify whether the user has the corresponding identity;
●Authorization: verifies whether an authenticated user has a certain permission. That is, determine whether the user can perform any operations
For example, verify whether a user has a role, or fine-grained verify whether a user has a permission on a resource!
●Session Manager: Session management, that is, after the user logs in, it is the first Session. All its information is in the Session before the user logs out.
The session can be a normal JavaSE environment or a Web environment;
●Cryptography: to protect the security of data, such as encrypted passwords stored in a database, rather than in clear text;
●Web Support: Web Support, can be very easy to integrate into the Web environment;
●Caching: For example, after a user logs in, the user information, roles, and permissions do not need to be checked every time. This improves efficiency
Concurrency Concurrency for multi-threaded applications is supported. For example, when a thread is opened within another thread, Concurrency is automatically transferred
On the past
●Testing: provide Testing support;
●Run As: allow – a user to pretend to be another user (if they allow) to access;
● This is a very common feature that allows you to log in once and then not log in the next time

●Subject: any ‘user’ who can interact with the application;
●Security Manager: equivalent to DispatcherServlet in SpringMVC; Is Shiro’s heart, through which all concrete interactions pass
The Security Manager controls, manages all the Subjects and is responsible for authentication, authorization, session, and cache management.
●Authenticator: responsible for Subject authentication, is an extension point, can be customized implementation; Authentication policies can be used
Strategy), that is, under what circumstances is the user authenticated;
●Authorizer: an Authorizer, that is, an access controller, used to determine whether a subject has permission to perform the corresponding operation; It controls the user’s access to the application
Those functions of;
● Realms: There can be one or more realms, which can be considered secure entity data sources. That is, secure entities can be obtained using DBC real
Now, it can also be memory implementation and so on, provided by the user; So you’ll need to implement your own realm in your applications
●SessionManager: a component that manages the Session lifecycle, Shiro can be used not only in Web environments, but also in general
JavaSE environment
●Authorizer: an Authorizer, that is, an access controller, used to determine whether a subject has permission to perform the corresponding operation; It controls the user’s access to the application
Those functions of; .
● Realms: There can be one or more realms that can be considered secure entity data sources. That is, secure entities can be obtained using DBC real
Now, it can also be memory implementation and so on, provided by the user; So all applications need to implement their own realm
●SessionManager: a component that manages the Session lifecycle, Shiro can be used not only in Web environments, but also in general
JavaSE environment
CH with English J”, Jane Feast:
●CacheManager: cache controller to manage caches such as users, roles, and permissions. Because these data basically change very little, put in slow
Storage can improve the performance of access;
●Cryptography: Cryptography module, Shiro improves — some common encryption components for password encryption, decryption, etc
