shiro保险框架用户传递更多信息的方法（用实体）
shiro安全框架用户传递更多信息的方法（用实体）
只要在认证的方法中传入bo那么以后从安全框架拿的就是bo,传的是string，安全框架拿的就是string

*
* Subject Security specific user 'view' of an application user. It can be a human being, a third-party process,
* a server connecting to you application application, or even a cron job. Basically, it is anything or
* anyone communicating with your application.
*
* PrincipalsA subjects identifying attributes. First name, last name, social security number, username
*
* Credentialssecret data that are used to verify identities. Passwords, Biometric data, x509 certificates,
*
* RealmsSecurity specific DAO, data access object, software component that talkts to a backend data source.
* If you have usernames and password in LDAP, then you would have an LDAP Realm that would communicate
* with LDAP. The idea is that you would use a realm per back-end data source and Shiro would know how
* to coordinate with these realms together to do what you have to do.
