1，需求

需求要求实现多个文件压缩为zip文件

2，代码

package com.example.demo;

import java.io.*;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

public class ZIP {

    public static void compressFiles(String zipPathDir, String zipFileName, List<String> fileList)  throws  Exception{
            ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(new File(zipPathDir + zipFileName)));
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(zos));
            File zipFile = new File(zipPathDir);
            if (!zipFile.exists()) {
                zipFile.mkdirs();
            }
            for (String filePath : fileList) {
                File file = new File(filePath);
                if (file.exists()) {
                    ZipEntry zipEntry = new ZipEntry(file.getName());
                    zos.putNextEntry(zipEntry);
                    Path path = Paths.get(filePath);
                    BufferedReader reader = new BufferedReader(new InputStreamReader(Files.newInputStream(path)));
                    while (reader.ready()) {
                        writer.write(reader.readLine());
                    }
                    writer.flush();
                    reader.close();
                    zos.closeEntry();
                }else{
                    //文件路径异常filePath：filePath
                }
            }
            zos.flush();
            writer.close();
    }

    public static void main(String[] args) throws  Exception{
        String zipPathDir ="D://test/";
        String zipFileName ="test.zip";
        List<String> fileList = new ArrayList<>();
        fileList.add("D://test/file.csv");
        fileList.add("D://test/1.txt");
        fileList.add("D://test/HelloWorld.txt");
        compressFiles( zipPathDir,  zipFileName,  fileList);
    }
