一个简单Java zip类压缩源代码

package com.zip;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.zip.Deflater;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

public class TestZipOut {
	public static void main(String[] args) {
		String[] filename = {"xiaoming.txt","xiaohong.txt"};
		String destName = "person2.zip";
		
		ZipOutputStream out = null;
		try {
			out = new ZipOutputStream(new FileOutputStream(destName));
			
			for(String file: filename){
				ZipEntry ze = new ZipEntry(file);
				out.putNextEntry(ze);				
				FileInputStream in = new FileInputStream(file);
				byte[] b = new byte[1024];
				int count = 0;
				while((count = in.read(b))!= -1){
					out.write(b);
				}
				
				in.close();
				out.closeEntry();
			}
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}finally{
			try {
				out.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		
	}
}
执行后:

使用ZLIB库 包装的压缩压缩文件的源码 VS2005 工程创建 /* */ class ZIPWRAP_EXP CZipper { public: CZipper(); virtual ~CZipper(); // simple interface static bool ZipFile(const char* szFilePath); // saves as same name with .zip static bool ZipFolder(const char* szFilePath, bool ignoreself = false); // saves as same name with .zip bool AddFolderToZipFile(const char*foldername, const char* rootfolder); bool AddFileToZipFile(const char*filename, const char*relfolder = NULL, const char* comment = NULL); bool AddFolderOnlyPathToFile(const char* foldername, const char* comment = NULL); bool OpenZipFile(const char* zipfilename, bool append = false); bool CloseZipFile(const char* global_comment = NULL); private: void* zipfile_;/* = NULL */ }; /* */ #define MAX_COMMENT (255) /* tm_unz contain date/time info */ typedef struct UZ_s { unsigned int tm_sec; /* seconds after the minute - [0,59] */ unsigned int tm_min; /* minutes after the hour - [0,59] */ unsigned int tm_hour; /* hours since midnight - [0,23] */ unsigned int tm_mday; /* day of the month - [1,31] */ unsigned int tm_mon; /* months since January - [0,11] */ unsigned int tm_year; /* years - [1980..2044] */ } UZ_s; // create our own fileinfo struct to hide the underlying implementation struct UZ_FileInfo { char szFileName[260 + 1]; char szComment[255 + 1]; unsigned long dwVersion; unsigned long dwVersionNeeded; unsigned long dwFlags; unsigned long dwCompressionMethod; unsigned long dwDosDate; unsigned long dwCRC; unsigned long dwCompressedSize; unsigned long dwUncompressedSize; unsigned long dwInternalAttrib; unsigned long dwExternalAttrib; bool bFolder; UZ_s tmu_date; }; class ZIPWRAP_EXP CUnZipper { public: CUnZipper(); virtual ~CUnZipper(); // simple interface static bool UnZip( const char* filename, const char* dstfolder, bool ingorepath = false, const char* password = NULL); bool OpenUnZipFile(const char* filename); bool CloseUnZipFile(); bool UnZipTo( const char* dstfolder, bool ingorepath = false, const char* password = NULL); int GetFileCount(); bool GotoFirstFile(); bool GotoNextFile(); bool GotoZipFile(int index); bool GotoZipFile(const char* zipfilename); bool GetCurrentFileInfo(UZ_FileInfo&fileinfo;); bool UnCurrentZipFile(const char* dstfolder, bool ingorepath = false, const char* password = NULL); bool UnOneZipFile(const char* filename, const char* dstfolder, bool ingorepath = false, const char* password = NULL); bool UnOneZipFile(int index, const char* dstfolder, bool ingorepath = false, const char* password = NULL); private: void* unzipfile_; };
