// The easiest way to create a Shiro SecurityManager with configured
// realms, users, roles and permissions is to use the simple INI config.
// We'll do that by using a factory that can ingest a .ini file and
// return a SecurityManager instance:
// Use the shiro.ini file at the root of the classpath
// (file: and url: prefixes load from files and urls respectively):
Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
SecurityManager securityManager = factory.getInstance();
// for this simple example quickstart, make the SecurityManager
// accessible as a JVM singleton. Most applications wouldn't do this
// and instead rely on their container configuration or web.xml for
// webapps. That is outside the scope of this simple quickstart, so
// we'll just do the bare minimum so you can continue to get a feel
// for things.
SecurityUtils.setSecurityManager(securityManager);

// get the currently executing user:
Subject currentUser = SecurityUtils.getSubject();
// 通过当前用户拿到session
