SpringMVC excel导出遇到的问题

问题：点击导出excel按钮后无反应

之前我使用的ajax来做的，点击后没有反应，调试了半天才发现ajax的方式行不通，不知道大神些是怎么玩的，反正我改成了form表单提交就可以了

1.form表单

<form id="exportData" action="<%=request.getContextPath() %>/logController/exportLukyBallDate.do" method="post">
			<input type="hidden" name="fileName" value="导出.xls"/>
			<input type="hidden" value='exportData' name="method" />
    </form>

2、js

function exportData(previous_id){
	alert("导出:"+previous_id);
	document.getElementById("previous_id").value=previous_id;
	document.getElementById("exportData").submit();
	
	}

3、Controller

@RequestMapping(value = "/logController")
public class DataHisBallController {
//excle导出
	@RequestMapping(value="/exportLukyBallDate")
	public String exportLukyBallDate(String getPreviousId,HttpServletRequest request,HttpServletResponse response){
		
		String previous_id = request.getParameter("previous_id");
		String fileName = request.getParameter("fileName");
		response.setContentType("application/ms-excel;charset=UTF-8");  
	        try {
		    response.setHeader("Content-Disposition", "attachment;filename=".concat(String.valueOf(URLEncoder.encode(fileName, "UTF-8"))));
			} catch (UnsupportedEncodingException e) {
				e.printStackTrace();
			} 
}
