Java 打包zip压缩文件，和读取不解压的zip文件

Java打包压缩包，简单代码如下：

//文件压缩到zip
@Test
public void createZip() throws IOException {
    ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(new File("hello.zip")));
    BufferedOutputStream bos = new BufferedOutputStream(zos);

    List<String> files = asList("log.txt");//文件列表

    for (String fileName : files) {
        File file = new File(fileName);
        ZipEntry zipEntry = new ZipEntry("file/" + file.getName());
        zos.putNextEntry(zipEntry);//设置即将用来写的文件

        FileInputStream fis = new FileInputStream(file);
        BufferedInputStream bis = new BufferedInputStream(fis);

        int read;
        while ((read = bis.read()) != -1){
            bos.write(read);
            bos.flush();
        }
    }
    zos.close();
}

Java读取压缩包，不解压zip直接读取文件内容：  

//读取压缩包
@Test
public void readZip() throws IOException {
    ZipFile zipFile = new ZipFile(new File("hello.zip"));
    Enumeration<? extends ZipEntry> entries = zipFile.entries();

    while (entries.hasMoreElements()){
        ZipEntry zipEntry = entries.nextElement();
        InputStream is = zipFile.getInputStream(zipEntry);

        BufferedReader reader = new BufferedReader(new InputStreamReader(is));

        String str;
        while ((str = reader.readLine()) != null){
            System.out.println(str);
        }
    }
}

可拷贝到自己代码中，main方法中运行，看看效果，
更多个性化使用，自行定制，
