在SSH框架下按条件分页查询

这里是按照条件模糊查询要查找的内容

在jsp页面：

<table align="center" class="table-showboat" cellpadding="0" cellspacing="0">
        <tr>
            <td align="right" colspan="14" height="30">

                <input type="button" value="查询" onclick="bclickcha()"><br>
                <input type="radio" value="中文名" name="ming" id="zh" checked="checked">中文名
                <input type="radio" value="英文名" name="ming" id="yi">英文名&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            </td>
        </tr>

js代码：

var bcha=document.getElementById("bchaxun");
    function bfocuscha(){
        bcha.value="";
    }
    function bclickcha(){
        var bxun=bcha.value;

在dao包中，如果模糊查询的条件不是外键的情况：
