背景是有一個(gè)上傳壓縮包，然后解析出指定出包名和版本的需求，直接上代碼：
接口：

    @PostMapping(value = "/upload")
    public Map<String,String> upload(@RequestParam("file") MultipartFile file){
        try {
            File zipFile = new File(FILE_UPLOAD_PATH + file.getOriginalFilename());
            file.transferTo(zipFile);
            return UploadAndUnzipUtils.getContainerName(zipFile.getAbsolutePath());
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

工具類：

package com.lenovo.common.utils;

import java.io.IOException;
import java.io.InputStream;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Map;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;


import org.w3c.dom.Document;
import org.w3c.dom.Element;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;


public class UploadAndUnzipUtils {

    public static Map<String,String> getContainerName(String zipFilePath) throws IOException {

        try {
            ZipFile zipFile = new ZipFile(zipFilePath);
            Enumeration<?> entries = zipFile.entries();

            while (entries.hasMoreElements()) {
                ZipEntry entry = (ZipEntry) entries.nextElement();
                if (entry.getName().equals("Container.xml")) {
                    Map<String,String> res = new HashMap<>();
                    InputStream inputStream = zipFile.getInputStream(entry);
                    DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
                    Document document = documentBuilder.parse(inputStream);
                    Element container = document.getDocumentElement();
                    res.put("name",container.getAttribute("name"));
                    res.put("version",container.getAttribute("version"));
                    return res;
                }
            }
        }catch (Exception e){

        }
        return null;
    }
}

如果稍微幫到你了記得點(diǎn)個(gè)喜歡點(diǎn)個(gè)關(guān)注~
