我是用ss2h做的我上传图片到服务器上，地址上传到数据库中，这是成功的，可是我删除就不行了，服务器上的图片删不了，获取不到img的值，我都找了好久了，实在没办法，还得请大神们看看
public String deleteTest(){
testBiz.delTest(shopPoster.getId());
String savePath = ServletActionContext.getServletContext().getRealPath(
""); // 获取项目根路径
savePath = savePath + "/upload/";
File file=new File(savePath+shopPoster.getContext());
file.delete();
resultMap="testActionshow.action";
return SUCCESS;
}
jsp上的 <script type="text/javascript">
function del(id){
location.href="shopEcsVoteOptiondeletePoster.action?shopPoster.id="+id
}
function ret(){
location.href="addPoster.jsp";
}
</script>
<body ><!--
<form action="shopEcsVoteOptiondeletePosters.action" method="post" name="myForm">
--><table align="center" border="1">
<s:iterator value="#request['listShopPoster']" var="listShopPoster">
<tr>
<td>
<img src="Poster/<s:property value="#listShopPoster.context"/>" height="50" width="50" />
</td>
<td>
<input type="button" value="删除" onclick="del(<s:property value="#listShopPoster.id"/>)">
</td>
</tr>
</s:iterator>
<tr>
<td>
<input type="button" value="继续添加" onclick="ret()">
</td>
</tr>
</table><!--
</form>
--></body>

给你传一个我用来删除图片的
- Java code
@Override public void init() throws ServletException { try { String tomcatPath = System.getProperty("user.dir"); String filePath = tomcatPath.substring(0,tomcatPath.length()-4)+"/webapps/ios/images"; File file = new File(filePath); if(file.exists()&&file.isDirectory()){ File [] files = file.listFiles(); for(int i=0;i<files.length;i++){ if(files[i].isFile()){ files[i].delete(); } } } System.out.println("<提示:清理图片缓存成功！>"); } catch (Exception e) { System.out.println("<提示:清理图片缓存失败！>"); e.printStackTrace(); } super.init(); }
