无法传递参数 apache shiro jsp sevlet

Question

表单提交后，参数没有传递给servlet。附上了 HTML 提交页面。在 shiro 中.ini文件具有 JDBC 领域。

 `<form name="loginForm" method="get" action="LoginCheckController">
        <table width="20%" bgcolor="0099CC" align="center">
            <input type="hidden" id="action"  name="page" value="home"/>
            <tr>
                <td colspan=2><center>
                        <font size=4><b>HTML Login Page</b></font>
                    </center></td>
            </tr>
            <tr>
                <td>Username:</td>
                <td><input name="username" id="username" type="text" size=25 ></td>
            </tr>
            <tr>
                <td>Password:</td>
                <td><input name="password" type="password" size=25 ></td>
            </tr>
            <tr>
                <td><input type="Reset"></td>
                <td><input type="submit" value="Login"></td>
            </tr>
        </table>
    </form>`

这是四郎.ini配置文件。 有一个JDBC领域。 它用于获取日志记录详细信息。 初始日志记录文件是登录.jsp。 所有参数都给出了空结果。
