  • shiro环境搭建

    参考shiro官方文档进行学习
    1.环境搭建
    采用eclipse + maven + jetty插件的方式
    使用版本1.2.4

    shiro.ini配置后期会采用数据库的方式,只需要简单了解即可,users表示当前可用登录用户,urls表示连接, authc表示需要登录hour才能使用,anon表示无需登录就可以使用

     1 [main]
 2 
 3 [users]
 4 kite=aaa123456
 5 tom=kite
 6 [urls]
 7 /index.jsp=authc
 8 /login.jsp=anon
 9 /login=anon
10 /index=authc

    login.jsp页面  用来登录

    <!DOCTYPE html>
<body>
    <h2>Hello World!</h2>
    <form action="login">
        username:<input type="text" name="username" /><br/>
        password:<input type="text" name="password" /><br/>
        <input type="submit"/>
    </form>
</body>
</html>

    index.jsp页面

5 </html>

    同过一个简单的helloWord案例来进入shiro
