iso9660
ISO 9660文件系统是一个标准的CD-ROM文件系统，它允许您在PC、Mac和其它主要计算机平台上读取CD-ROM文件。
------摘自百度百科
使用genisoimage linux命令的方式打包iso9660
String shellCommand = "genisoimage -input-charset utf-8 -o " + isoTempPath + " -iso-level 1 -r -l " + targetFileDir;
其中的isoTempPath 是生成iso的存储路径，targetFileDir是默认把这个文件夹下所有的文件都打进iso包里。
这种方式依赖服务器安装的genisoimage命令，如果做服务迁移得确保服务器中安装了这个命令。
纯java实现iso9660
在github上找到一个国外大佬的实现方式：https://github.com/stephenc/java-iso-tools.git
可以把源码下载下来，在examples文件夹里有使用方法介绍。
或者看我下面总结的：
maven引入：
<dependency>
<groupId>com.github.stephenc.java-iso-tools</groupId>
<artifactId>iso9660-writer</artifactId>
<version>2.1.0</version>
</dependency>
<dependency>
<groupId>com.github.stephenc.java-iso-tools</groupId>
<artifactId>loop-fs-iso-impl</artifactId>
<version>2.0.1</version>
</dependency>
打包
新建IsoCreation工具类：

import java.io.File;
import java.io.FileNotFoundException;
import com.github.stephenc.javaisotools.eltorito.impl.ElToritoConfig;

JolietConfig jolietConfig;
ElToritoConfig elToritoConfig;
// This is a conversion of https://github.com/danveloper/provisioning-gradle-plugin/blob/

public IsoCreation() {
root = new ISO9660RootDirectory();
}
public void insertFile(File passedInsert) {
try {
root.addContentsRecursively(passedInsert);
} catch (HandlerException e) {
e.printStackTrace();
}
}
public ISO9660Config setIsoConfig(String volumeId) {
//Let's make a new configuration for the basic file system
iso9660config = new ISO9660Config();
iso9660config.allowASCII(false);
//The standard says you are not allowed more than 8 levels, unless you enable RockRidge support
iso9660config.restrictDirDepthTo8(true);
//Set the volume ID
try {
iso9660config.setVolumeID(volumeId.substring(0, Math.min(volumeId.length(), 15)));
} catch (ConfigException e) {
e.printStackTrace();
}
iso9660config.forceDotDelimiter(false);
try {
iso9660config.setInterchangeLevel(3);
} catch (ConfigException e) {
e.printStackTrace();
}
return iso9660config;
}
public RockRidgeConfig setRockConfig() {
rockConfig = new RockRidgeConfig();
rockConfig.setMkisofsCompatibility(false);
rockConfig.hideMovedDirectoriesStore(true);
rockConfig.forcePortableFilenameCharacterSet(true);
return rockConfig;
}
public JolietConfig setJolietConfig(String volumeId) {
jolietConfig = new JolietConfig();
try {
//Not sure if there is a limit here, but it seems most names are fine
jolietConfig.setVolumeID(volumeId);
} catch (ConfigException e) {
e.printStackTrace();
}
jolietConfig.forceDotDelimiter(false);
return jolietConfig;
}
/**
* This is for boot information on the iso
*
* @return The finalized config.
*/
public ElToritoConfig setElToritoConfig(){
elToritoConfig = null;
return elToritoConfig;
}
/**
* Close out the disc.
* @param isoPath
*/
public void finalizeDisc(File isoPath) {
ISOImageFileHandler handler = null;
try {
handler = new ISOImageFileHandler(isoPath);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
try {
CreateISO iso = new CreateISO(handler, root);
try {
iso.process(iso9660config, rockConfig, jolietConfig, elToritoConfig);
} catch (HandlerException e) {
e.printStackTrace();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
封装createIso方法
public static void createIso(String inputFileDir, String outIsoPath) {
//Create a new root of our disc
IsoCreation sampleCreation = new IsoCreation();
//Add our files, you have to give a directory to use the recusively adding function
sampleCreation.insertFile(new File(inputFileDir));
//This is the base iso9660 standard file system
sampleCreation.setIsoConfig("test");
//To quote wikipedia "Rock Ridge is an extension to the ISO 9660 volume format, commonly used on CD-ROM and
// DVD media, which adds POSIX file system semantics."
// sampleCreation.setRockConfig();
//This is another extension to the standard after Windows 95 to add support for longer filenames
sampleCreation.setJolietConfig("test");
//El Torito is boot information for the disc
// sampleCreation.setElToritoConfig();
//Finalize and save our ISO
sampleCreation.finalizeDisc(new File(outIsoPath));
}
然后调用这个方法
createIso(targetFileDir, isoTempPath);
其中targetFileDir是要打包的文件夹 isoTempPath是打包之后iso存储的路径，如此就可以打包成功。
解压包
新建ReadIso工具类：
package org.openjfx.offlinepackage.utils;
import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import com.github.stephenc.javaisotools.loopfs.iso9660.Iso9660FileEntry;
import com.github.stephenc.javaisotools.loopfs.iso9660.Iso9660FileSystem;
/***
* This is a adaptation of https://github.com/danveloper/provisioning-gradle-plugin/blob/master/src/main/groovy/
* gradle/plugins/provisioning/tasks/image/ImageAssemblyTask.groovy
*/
public class ReadIso {
Iso9660FileSystem discFs;
public ReadIso(File isoToRead, File saveLocation) {
try {
//Give the file and mention if this is treated as a read only file.
discFs = new Iso9660FileSystem(isoToRead, true);
} catch (IOException e) {
e.printStackTrace();
}
//Make our saving folder if it does not exist
if (!saveLocation.exists()) {
saveLocation.mkdirs();
}
//Go through each file on the disc and save it.
for (Iso9660FileEntry singleFile : discFs) {
if (singleFile.isDirectory()) {
new File(saveLocation, singleFile.getPath()).mkdirs();
} else {
File tempFile = new File(saveLocation, singleFile.getPath());
try {
//This is java 7, sorry if that is too new for some people
Files.copy(discFs.getInputStream(singleFile), tempFile.toPath());
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
调用下面方法解压包：
ReadIso tempIso = new ReadIso(new File("test.iso"), new File("test directory"));
其中第一个参数是iso的File对象，第二个参数是解压路径的File对象。
至此java实现iso9660打包和解包都可实现，完结撒花~
