我正在创建一个程序，它将解压缩一个zip，然后将文件插入到数据库中，每隔一段时间我就会得到错误

java.lang.Exception: java.io.EOFException: Unexpected end of ZLIB input stream

我不能找出原因，因为提取代码是几乎相同的所有其他代码，你可以在网上找到。我的代码如下：

public void extract(String zipName, InputStream content) throws Exception {

    int BUFFER = 2048;

    //create the zipinputstream 
    ZipInputStream zis = new ZipInputStream(content);

    //Get the name of the zip
    String containerName = zipName;

    //container for the zip entry
    ZipEntry entry;

    // Process each entry
    while ((entry = zis.getNextEntry()) != null) {

        //get the entry file name
        String currentEntry = entry.getName();

        try {

                ByteArrayOutputStream baos = new ByteArrayOutputStream();

                // establish buffer for writing file
                byte data[] = new byte[BUFFER];
                int currentByte;

                // read and write until last byte is encountered
                while ((currentByte = zis.read(data, 0, BUFFER)) != -1) {

                    baos.write(data, 0, currentByte);
                }

                baos.flush(); //flush the buffer 

                //this method inserts the file into the database
                insertZipEntry(baos.toByteArray());

                baos.close();

        } 
        catch (Exception e) {
            System.out.println("ERROR WITHIN ZIP " + containerName);
        }
    }
}
