程式大意解讀:
1. Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
SecurityManager securityManager = factory.getInstance();
讀取配置檔案擷取SecurityManager執行個體;
2. SecurityUtils.setSecurityManager(securityManager);
Subject currentUser = SecurityUtils.getSubject();
Session session = currentUser.getSession();
securityManager作為參數擷取“目前操作使用者”currentUser ,擷取目前使用者(被shiro架構封裝好)的session執行個體;
3. UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
token.setRememberMe(true);
生成使用者名/密碼密碼,并選擇了記住我(實用cookie儲存了帳号的資訊);
4. log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");
if (currentUser.hasRole("schwartz")) {
log.info("May the Schwartz be with you!");
} else {
log.info("Hello, mere mortal.");
}
