Vulgarisons d'abord ce qu'est Shiro. Le nom original de Shiro est Apache Shiro. Il s'agit d'un framework de sécurité (autorisation) Java. Shiro facilite le développement d'applications suffisamment performantes qui peuvent être utilisées non seulement dans l'environnement JavaSE, mais également dans l'environnement JavaEE. Shiro peut effectuer l'authentification, l'autorisation, le cryptage, la gestion de session, l'intégration Web, la mise en cache et d'autres applications avancées. Voir le schéma de fonction et d'architecture de shiro comme indiqué sur la figure :
Sans plus tarder, Springboot intègre shiro, passons directement au code
