Java实现文件压缩

最近碰到了关于Java实现文件压缩的问题，在这里记录下代码：

 

public File fileCompress(File file){

    File zipfile = new File(FilenameUtils.getFullPath(file.getAbsolutePath())
                .concat(FilenameUtils.getBaseName(file.getAbsolutePath()))
                .concat(".zip"));
    BufferedInputStream br = null;
    ZipOutputStream zos = null;
    try{
        zos = new ZipOutputStream(new FileOutputStream(zipfile));
        zos.putNextEntry(new ZipEntry(file.getName()));
        br = new BufferedInputStream(new FileInputStream(file));
        byte[] by = new byte[2 * 1024 * 1024];
        int c = 0;
        while((c = br.read(by)) != -1) {
            zos.write(by,0,c);
        }
        zos.flush();
    } catch(Exception e){

    } finally {
        if(br != null) {
           try{
               br.close();
           } catch (IOException e) {

           }
         }

        if(zos != null) {
           try{
               zos.close();
           } catch (IOException e) {

           }
         }
    }

    return zipfile;
}
