jsp按钮怎么传递两个参数给后台

通过get传参方式.不过这种情况会有get请求乱码问题.
jsp页面:

<td><a href="#" οnclick="openDialogView('查看平台管理-企业金融-审核记录', '${ctx}/approvedmemo/businessFinance/form?businessType=${businessFinance.businessType}&id=${businessFinance.id}','800px', '500px')">
<fmt:formatDate value="${businessFinance.auditTime}" pattern="yyyy-MM-dd HH:mm:ss"/>
</a></td>

Java代码

@RequestMapping(value = "form")
public String form(BusinessFinance businessFinance, Model model) {
model.addAttribute("businessFinance", businessFinance);
return "modules/om/approvedmemo/businessFinanceForm";
}
