Zip4j支持创建拆分zip文件.这是一个创建拆分zip文件的示例(样本取自Zip4j examples package)

ZipFile.createZipFile(File sourceFile, ZipParameters parameters, boolean splitArchive, long splitLength)

是创建拆分zip文件的方法.在这种情况下,boolean splitArchive必须设置为true.您可以通过long splitLength为每个拆分文件(z01,z02等)设置最大文件大小

import java.util.ArrayList;

import net.lingala.zip4j.exception.ZipException;

public class CreateSplitZipFile {

public CreateSplitZipFile() {

try {

// Initiate ZipFile object with the path/name of the zip file.

ZipFile zipFile = new ZipFile("c:\ZipTest\CreateSplitZipFile.zip");

// Build the list of files to be added in the array list

// Objects of type File have to be added to the ArrayList

ArrayList filesToAdd = new ArrayList();

filesToAdd.add(new File("c:\ZipTest\sample.txt"));

filesToAdd.add(new File("c:\ZipTest\myvideo.avi"));

filesToAdd.add(new File("c:\ZipTest\mysong.mp3"));

// Initiate Zip Parameters which define various properties such

// as compression method, etc.

ZipParameters parameters = new ZipParameters();

// set compression method to store compression

parameters.setCompressionMethod(Zip4jConstants.COMP_DEFLATE);

// Set the compression level. This value has to be in between 0 to 9

parameters.setCompressionLevel(Zip4jConstants.DEFLATE_LEVEL_NORMAL);

// Create a split file by setting splitArchive parameter to true

// and specifying the splitLength. SplitLenth has to be greater than

// 65536 bytes

// Please note: If the zip file already exists, then this method throws an

// exception

zipFile.createZipFile(filesToAdd, parameters, true, 10485760);

e.printStackTrace();
