Java读取Zip

1. 读取所有entry,并输出entry内容:

private void readAllEntries(Path path) throws IOException {
        ZipFile zipFile = new ZipFile(path.toFile());
        try(InputStream inputStream = Files.newInputStream(path)){
            ZipInputStream zipInputStream = new ZipInputStream(inputStream);
            ZipEntry zipEntry;
            while ((zipEntry = zipInputStream.getNextEntry()) != null){
                LOG.info("entry={}, is directory={}", zipEntry.getName(), zipEntry.isDirectory());
                if(zipEntry.isDirectory()){
                    continue;
                }
                final InputStream inputStream1 = zipFile.getInputStream(zipEntry);
                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream1, StandardCharsets.UTF_8));
                StringBuilder sb = new StringBuilder();
                String line;
                while ((line = bufferedReader.readLine()) != null){
                    sb.append(line).append(System.getProperty("line.separator"));
                }
                LOG.info("{}的内容{}", zipEntry.getName(), sb.toString());
                bufferedReader.close();
            }
                    zipInputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

2. 递归读取zip中的zip

public void readZipFileRecursive(final Path zipFile) {
        try (final InputStream zipFileStream = Files.newInputStream(zipFile)) {
            this.readZipFileStream(zipFileStream);
        } catch (IOException e) {
            LOG.error("error reading zip file %s!", zipFile, e);
        }
    }

    private void readZipFileStream(final InputStream zipFileStream) {
        final ZipInputStream zipInputStream = new ZipInputStream(zipFileStream);
        ZipEntry zipEntry;
        try {
            while ((zipEntry = zipInputStream.getNextEntry()) != null) {
                LOG.info("name of zip entry: {}, directory? {}", zipEntry.getName(), zipEntry.isDirectory());
                if (!zipEntry.isDirectory() && zipEntry.getName().endsWith(".zip")) {
                    this.readZipFileStream(zipInputStream); // recursion
                }
            }
                     zipInputStream.close();
        } catch (IOException e) {
            LOG.error("error reading zip file stream", e);
        }
    }
