• 本例中使用连接池。
• 注：密码为空就填双引号，但是不能不填。

• 测试类

public class TestMain {
    public static void main(String[] args) {

        
        Factory<SecurityManager> factory=new IniSecurityManagerFactory("classpath:shiro.ini");
        SecurityManager securityManager=factory.getInstance();
        
        SecurityUtils.setSecurityManager(securityManager);
        
        Subject subject=SecurityUtils.getSubject();
        UsernamePasswordToken token=new UsernamePasswordToken("admin", "12342");
        
        try {
            subject.login(token);
            System.out.println("登录成功");
        } catch (UnknownAccountException e) {
            System.out.println("用户名错误");
        }catch(IncorrectCredentialsException e){
            System.out.println("密码错误");
        }
        
        System.out.println(securityManager);
        
    }
}

• 数据库。注意：这里的userName和password不能修改为其他名字，而且表明users也不能修改.

•  结果：
