}文件是可以上传了，但是返回值，总是提示下载，奇怪的很，请高人帮忙呀！
我是采用注解的方式呀。@Action(value = "imageUpload", results = { @Result(name = "success", type = "json") }, params = { "contentType", "text/html" })
楼主是用的struts2的json插件吧，struts.xml中继承一下，然后修改一下<struts>
<package name="struts2.1" extends="json-default">
<result name="success" type="json">
<param>.....</param>
</result>
</package>
</struts>这里推荐楼主使用google的Gson工具
我是采用的注解的方式的，不用struts.xml的配置文件的呀。
