Java 壓縮圖片并打包成ZIP文件的示例
更新時(shí)間：2020年12月02日 17:04:15 作者：煙-波-天-客
這篇文章主要介紹了Java 壓縮圖片并打包成ZIP文件的示例，幫助大家更好的理解和使用Java，感興趣的朋友可以了解下
JAVA 獲取網(wǎng)絡(luò)圖片或本地圖片壓縮后打成ZIP，但是獲取網(wǎng)絡(luò)流存在問(wèn)題：每次獲取圖片流的大小不一樣（圖片不完整），以致無(wú)法構(gòu)建圖片進(jìn)行壓縮？
/*
釋以下代碼：即可獲取完整圖片流網(wǎng)絡(luò)不穩(wěn)定情況且網(wǎng)絡(luò)流是順序讀取，所以獲得前部份流，不需要關(guān)閉連接，只需要將用完的流關(guān)閉即可
