记一次Docker容器中写出文件编码错误

时间：2018-7-31

现象：项目在本地启动下载文件压缩后，没有出现乱码问题，但在docker容器中部署项目后，写出文件压缩后中文乱码

解决过程: 首先在代码中尝试了多种写出方法。因为有文件需要压缩，使用最java自带工具类java.util.zip,出现了乱码（乱码为？？？）。此时想到的肯定是自己java编码压缩有问题，然后又换成了org.apache.tools.zip还是乱码，那我就想了啊，是不是在压缩前生成文件时就乱码了呢？

一看文件果然是输出文件时文件名就已经乱码了，此时想到的就是Java 的系统属性 sun.jnu.encoding 的编码问题，然后在系统中打印出来，如图，系统编码为ANSI_X3.4-1968,

顿时感觉问题有希望解决了,在输出文件之前添加了System.setProperty("sun.jnu.encoding","utf-8");此时再打印出来

 虽然已经改成了utf-8但是文件输出的还是乱码，这时候真的很尴尬了，试过很多方法从代码下手试过很多方法依旧不行，此时心里严重怀疑是机器问题，上网查询了一下关于docker编码的问题，发现大家的却经常碰到docker中文编码错误，想去找dockerfile文件看一下，然而怎么找都找不到，问管服务器的人，那人也不吊我，实在没办法硬着头皮让那人换了一个docker镜像(换的这个dokcer镜像是其他项目使用的，文件写出没有问题)，然后！然后就好了！此时再去看看java的系统变量编码sun.jnu.encoding就成了utf-8。

 果然还是系统编码问题，大家以后还是要相信自己的判断啊！当然前提是要从自身开始找问题，若尝试过各种方法还是不行，就要换一个思路去解决了！不能走进死胡同！

附文件压缩代码：

        String txtFileName = new String("测试文本.txt");
        String txtContent = new String("测试文本内容");
System.out.println("sun.jnu.encoding"+System.getProperty("sun.jnu.encoding"));
        File fileDir = new File(sysDir);
        if(!fileDir.exists()){
            fileDir.mkdirs();
        }
        try {
            OutputStreamWriter oStreamWriter = new OutputStreamWriter(new FileOutputStream(sysDir+File.separator+txtFileName), "utf-8");
            oStreamWriter.append(txtContent);
            oStreamWriter.flush();
            oStreamWriter.close();
        }catch (IOException e){

//            ZipEntry entry = new ZipEntry(baseDir + new String(file.getName().getBytes(systemEncoding),"UTF-8"));
            ZipEntry entry = new ZipEntry(zipDir+file.getName());
            zos.putNextEntry(entry);
            int count;
            byte[] buf = new byte[1024];
            while ((count = bis.read(buf)) != -1) {
                zos.write(buf, 0, count);
            }
            bis.close();

        } catch (Exception e) {
            // TODO: handle exception

        }
    }

    private static void compressDir(File dir, ZipOutputStream zos,String zipDir) {
        if (!dir.exists())
            return;
        File[] files = dir.listFiles();
        if(files.length == 0){
            try {
                zos.putNextEntry(new ZipEntry(zipDir + dir.getName()+File.separator));
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        for (File file : files) {
            compressbyType(file, zos, zipDir + dir.getName() + File.separator);
