apache ant进行zip解压缩操作示例分享
需要导入ant.jar包，apache网站（http://ant.apache.org/bindownload.cgi）下载即可。复制代码代码如下:
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipOutputStream;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.taskdefs.Expand;
import org.apache.tools.zip.ZipEntry;
import com.xyq.io.util.CloseIoUtil;
public class ZipUtil {
private static final String ENCODE = "UTF-8";
public static void zip(String inputFilePath, String zipFileName) {
File inputFile = new File(inputFilePath);
if (!inputFile.exists())
throw new RuntimeException("原始文件不存在!!!");
File basetarZipFile = new File(zipFileName).getParentFile();
if (!basetarZipFile.exists() && !basetarZipFile.mkdirs())
throw new RuntimeException("目标文件无法创建!!!");
BufferedOutputStream bos = null;
FileOutputStream out = null;
ZipOutputStream zOut = null;
try {
// 创建文件输出对象out,提示:注意中文支持
out = new FileOutputStream(new String(zipFileName.getBytes(ENCODE)));
bos = new BufferedOutputStream(out);
// 將文件輸出ZIP输出流接起来
zOut = new ZipOutputStream(bos);
zip(zOut, inputFile, inputFile.getName());
CloseIoUtil.closeAll(zOut, bos, out);
} catch (Exception e) {
e.printStackTrace();
}
}
private static void zip(ZipOutputStream zOut, File file, String base) {
try {
// 如果文件句柄是目录
if (file.isDirectory()) {
// 获取目录下的文件
File[] listFiles = file.listFiles();
// 建立ZIP条目
zOut.putNextEntry(new ZipEntry(base + "/"));
base = (base.length() == 0 ? "" : base + "/");
if (listFiles != null && listFiles.length > 0)
// 遍历目录下文件
for (File f : listFiles)
// 递归进入本方法
zip(zOut, f, base + f.getName());
}
// 如果文件句柄是文件
else {
if (base == "") {
base = file.getName();
}
// 填入文件句柄
zOut.putNextEntry(new ZipEntry(base));
// 开始压缩
// 从文件入流读,写入ZIP 出流
writeFile(zOut, file);
}
} catch (Exception e) {
e.printStackTrace();
}
}
private static void writeFile(ZipOutputStream zOut, File file)
throws IOException {
FileInputStream in = null;
BufferedInputStream bis = null;
in = new FileInputStream(file);
bis = new BufferedInputStream(in);
int len = 0;
byte[] buff = new byte;
while ((len = bis.read(buff)) != -1)
zOut.write(buff, 0, len);
zOut.flush();
CloseIoUtil.closeAll(bis, in);
}
