Shiro中的jdbcRealm工具类(2)

JdbcRealm的方式访问数据库，通过与数据库的连接，验证相应的登录用户与授权。

mysql数据库表

CREATE TABLE users(
    id BIGINT(30) PRIMARY KEY AUTO_INCREMENT,
    username VARCHAR(40),
    PASSWORD VARCHAR(40)
)

注意：数据库表必须是users

public class Shiro_Realm_Dey02 {

    public static void main(String[] args) {
        //创建工厂类
        Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:jdbc_realm.ini");
        //jdbc_realm.ini文件的数据
        SecurityManager securityManager = factory.getInstance();
        //获取当前用户
        SecurityUtils.setSecurityManager(securityManager);
        Subject user = SecurityUtils.getSubject();

        //通过usernamePasswordToken来模拟html/jsp传递过来的用户名和密码
        UsernamePasswordToken token = new UsernamePasswordToken("admin", "123");
        try {
            user.login(token);
            System.out.println("登录成功");
        } catch (AuthenticationException e) {
            e.printStackTrace();
            System.out.println("登录失败");
        }
    }

}

直接通过mian方法启动项目就出结果了。
