shiro环境搭建

参考shiro官方文档进行学习

http://shiro.apache.org/java-authentication-guide.html

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

<!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>
