JAVA操作ZIP文件

第一种:

import java.io.BufferedInputStream;   
import java.io.File;   
import java.io.FileInputStream;   
import java.io.FileOutputStream;   
import java.util.zip.CRC32;   
import java.util.zip.CheckedOutputStream;   
  
import org.apache.tools.zip.ZipEntry;   
import org.apache.tools.zip.ZipOutputStream;   
  
public class ZipCompressor {   
    static final int BUFFER = 8192;   
  
    private File zipFile;   
  
    public ZipCompressor(String pathName) {   
        zipFile = new File(pathName);   
    }   
  
    public void compress(String srcPathName) {   
        File file = new File(srcPathName);   
        if (!file.exists())   
            throw new RuntimeException(srcPathName + "不存在！");   
        try {   
            FileOutputStream fileOutputStream = new FileOutputStream(zipFile);   
            CheckedOutputStream cos = new CheckedOutputStream(fileOutputStream,   
                    new CRC32());   
            ZipOutputStream out = new ZipOutputStream(cos);   
            String basedir = "";   
            compress(file, out, basedir);   
            out.close();   
        } catch (Exception e) {   
            throw new RuntimeException(e);   
        }   
    }   
  
    private void compress(File file, ZipOutputStream out, String basedir) {   
        /* 判断是目录还是文件 */  
        if (file.isDirectory()) {   
            System.out.println("压缩：" + basedir + file.getName());   
            this.compressDirectory(file, out, basedir);   
        } else {   
            System.out.println("压缩：" + basedir + file.getName());   
            this.compressFile(file, out, basedir);   
        }   
    }   
  
    /** 压缩一个目录 */  
    private void compressDirectory(File dir, ZipOutputStream out, String basedir) {   
        if (!dir.exists())   
            return;   
  
        File[] files = dir.listFiles();   
        for (int i = 0; i < files.length; i++) {   
            /* 递归 */  
            compress(files[i], out, basedir + dir.getName() + "/");   
        }   
    }   
  
    /** 压缩一个文件 */  
    private void compressFile(File file, ZipOutputStream out, String basedir) {   
        if (!file.exists()) {   
            return;   
        }   
        try {   
            BufferedInputStream bis = new BufferedInputStream(   
                    new FileInputStream(file));   
            ZipEntry entry = new ZipEntry(basedir + file.getName());   
            out.putNextEntry(entry);   
            int count;   
            byte data[] = new byte[BUFFER];   
            while ((count = bis.read(data, 0, BUFFER)) != -1) {   
                out.write(data, 0, count);   
            }   
            bis.close();   
        } catch (Exception e) {   
            throw new RuntimeException(e);   
        }   
    }   
}  

 

第二种：

import java.io.File;   
  
import org.apache.tools.ant.Project;   
import org.apache.tools.ant.taskdefs.Zip;   
import org.apache.tools.ant.types.FileSet;   
  
public class ZipCompressorByAnt {   
  
    private File zipFile;   
  
    public ZipCompressorByAnt(String pathName) {   
        zipFile = new File(pathName);   
    }   
       
    public void compress(String srcPathName) {   
        File srcdir = new File(srcPathName);   
        if (!srcdir.exists())   
            throw new RuntimeException(srcPathName + "不存在！");   
           
        Project prj = new Project();   
        Zip zip = new Zip();   
        zip.setProject(prj);   
        zip.setDestFile(zipFile);   
        FileSet fileSet = new FileSet();   
        fileSet.setProject(prj);   
        fileSet.setDir(srcdir);   
        //fileSet.setIncludes("**/*.java"); 包括哪些文件或文件夹 eg:zip.setIncludes("*.java");   
        //fileSet.setExcludes(...); 排除哪些文件或文件夹   
        zip.addFileset(fileSet);   
           
        zip.execute();   
    }   
}  

 测试类：

public class TestZip {
	public static void main(String[] args) {
		//ZipCompressor zc = new ZipCompressor("E:\\szhzip.zip");
		//zc.compress("E:\\test");

		ZipCompressorByAnt zca = new ZipCompressorByAnt("E:\\111.zip");
		zca.compress("E:\\111");
	}
}
