Java implements an example of directly reading Zip files and file contents without decompression

本篇文章主要介绍了详解Java无需解压直接读取Zip文件和文件内容，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

整理文档，搜刮出一个Java无需解压直接读取Zip文件和文件内容的代码，稍微整理精简一下做下分享。

package test;

import java.io.BufferedInputStream; 
import java.io.BufferedReader; 
import java.io.FileInputStream; 
import java.io.InputStream; 
import java.io.InputStreamReader; 
import java.util.zip.ZipEntry; 
import java.util.zip.ZipFile; 
import java.util.zip.ZipInputStream; 


public class aaaa {

  public static void main(String[] args) throws Exception {
    try { 
        readZipFile("D:\\ztree.zip"); 
      } catch (Exception e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
      } 
  }
  
  public static void readZipFile(String file) throws Exception { 
      ZipFile zf = new ZipFile(file); 
      InputStream in = new BufferedInputStream(new FileInputStream(file)); 
      ZipInputStream zin = new ZipInputStream(in); 
      ZipEntry ze; 
      while ((ze = zin.getNextEntry()) != null) { 
        if (ze.isDirectory()) {
        } else { 
          System.err.println("file - " + ze.getName() + " : " 
              + ze.getSize() + " bytes"); 
          long size = ze.getSize(); 
          if (size > 0) { 
            BufferedReader br = new BufferedReader( 
                new InputStreamReader(zf.getInputStream(ze))); 
            String line; 
            while ((line = br.readLine()) != null) { 
              System.out.println(line); 
            } 
            br.close(); 
          } 
          System.out.println(); 
        } 
      } 
      zin.closeEntry(); 
    } 
}
