1、struts.xml
<action name="downLoad" class="org.wll.prj.action.HelloAction" method="exportFile">
</action>
2、export.jsp
<script type="text/javascript">
function daochu()
{
window.document.forms[0].submit();
}
</script>
<body>
<form action="<%=path%>/downLoad.action?method=exportFile" method="post">
<input id="wll" name="wll" value="helloworld!"></input>
</form>
This is my JSP page. <br>
<button onclick="daochu();">点击</button>
</body>
3、导出文件action
public void exportFile() throws Exception {
request = ServletActionContext.getRequest();
response = ServletActionContext.getResponse();
String[] ss = request.getParameterValues("wll");
String filepath = "D://test.txt";
response.setContentType("application/octet-stream; charset=gbk");
response.setHeader("Content-disposition", "attachment; filename=\"" + filepath + "\"");
PrintWriter pw = null;
try {
pw = response.getWriter();
pw.print(ss[0]);
pw.println("");
} catch (Exception e) {
// TODO: handle exception
}finally{
}
