Linux上上传跟Windows上上传不一样，在Windows上测试没问题，但是放到Linux服务器上跑，上传的文件中文显示乱码。解决方案：

文件内容构建处：

private static String encoding = System.getProperty("file.encoding");//获取当前系统编码，Windows跟Linux不同，这样可以自动获取处理编码

.....

// 上传到EcssCus
String remotefilename = "\\EcssCus\\" + orderNo + ".xml";
// 上传到Ciq
String remotefilename1 = "\\Ciq\\" + orderNo + ".xml";
// 上传到EcssOrders
String remotefilename2 = "\\Ciq\\Orders\\" + orderNo + ".xml";

} catch (UnsupportedEncodingException e) {
e.printStackTrace();
