我从示例代码中复制了这个以使用zip4j,特别是名为CreateSplitZipFileFromFolder.java
问题是,即使我将createZipFileFromFolder
的第三个参数设置为true,当我调用方法ZipFile.isSplitArchive()
看来它只是将ZipModel
对象设置为我设置的布尔标志,但是我得到了一个不同的值。任何想法为什么会这样?
答案 0 :(得分:1)
生成的ZIP文件是否大于splitLength
字节(在您的示例中为10485760)?来自createZipFile
如果必须拆分存档,则必须拆分
的字节长度
我假设只有在大于该大小的情况下才会创建拆分Zip文件。
