, the configuration is relatively troublesome, so generally, applications use custom reaml, create a custom JDBC readml and demonstrate the process of combining reaml with java programs.Because you need to create a database (create three tables: User, role, and permission, and associate the primary and Foreign keys in turn), first introduce the database driver jar package; in shiro, in the INI file, specify that the authentication policy used by the current securityManager is custom jdbcReaml.[m
