java - ZipOutputStream 提示 FileNotFoundException

Question

new_file_name 类似于 2013-03-15-08:59:10_65.zip

 fileZip = new ZipOutputStream(new FileOutputStream(new File(new_file_name)));
    byte[] buffer = new byte[1024];
    try{
        for(String fileName:fileList)
        {
            FileInputStream in = null;
            try{
                File file = new File(fileName);
                ZipEntry ze = new ZipEntry(fileName);
                fileZip.putNextEntry(ze);
                in = new FileInputStream(file);
                int len = 0;
                while((len = in.read(buffer)) > 0) {
                    fileZip.write(buffer, 0, len);
                }
                fileZip.closeEntry();
                in.close();
            } catch (Exception e) {
                log(0, "Exception writing "+fileName+" to "+new_file_name+": "+e.toString());
        }

我收到此异常 Exception writing to 2013-03-15-09:28:20_65.zip: java.io.FileNotFoundException: (No such file or directory)

该目录具有完全权限。我也看到在文件夹中创建了一个文件，我也尝试给出 getAbsolutePath()，仍然给了我同样的异常。

Answer 1

我编写了一些实用方法，使用 NIO.2 文件 API(该库是开源的)将目录复制到 Zip 文件或从 Zip 文件复制目录:

Maven:

<dependency>  
    <groupId>org.softsmithy.lib</groupId>  
    <artifactId>softsmithy-lib-core</artifactId>  
    <version>0.3</version>  
</dependency>

API:CopyFileVisitor.copy

也许您发现它很有用。
