dom4j 生成xml windows 是GB2312中文正常，linux是乱码解决方法

 OutputFormat format = OutputFormat.createPrettyPrint();
                format.setEncoding("GB2312");
            file = new File(configHandler.getExportPath() + "/" + fileName);
            FileWriterWithEncoding fw = new FileWriterWithEncoding(file,"GB2312");
            output = new XMLWriter(fw,format);
            output.write(document);
