吸收了很多网上的方案，发现掺合起来才好使。。。。
1. 上传 form传参 a要使用过滤器utf-8 b页面设置成utf-8 c 使用struts1.1以上版本
2. 下载 url传参，过滤器居然不好用。把tomcat server.xml URIEncode设成 utf-8传进来的参数终于不是乱码了。
但是下载时的名字还是乱码。又在网上查了好多方法 URLEncode 啥的都不好用
开始设成 String name = new String(uForm.getFileName().getBytes("utf-8"),
"ISO8859_1");
firefox下载的名字终于对了，ie还是乱码....
最后设成 String name = new String(uForm.getFileName().getBytes(""),
"ISO8859_1");
最后是这个写的终于通过了 下载时都是正确的中文名字了。
贴代码吧~ 没有用到spring action 继承struts的就好了 没必要继承 ActionSupport
