SpringBoot壓縮png, jpg, jpeg, webp類型圖片的實(shí)現(xiàn)代碼

更新時(shí)間：2024年08月26日 09:22:54 作者：三過(guò)食堂而不入

這篇文章主要介紹了SpringBoot壓縮png, jpg, jpeg, webp類型圖片的實(shí)現(xiàn),文中通過(guò)代碼示例和圖文結(jié)合的方式給大家講解的非常詳細(xì),對(duì)大家的學(xué)習(xí)或工作有一定的幫助,需要的朋友可以參考下

1.需求

業(yè)務(wù)要求對(duì)png, jpg, jpeg, webp 格式圖片進(jìn)行等比例壓縮

2.開(kāi)發(fā)中遇到的問(wèn)題

使用 Thumbnails 包, 發(fā)現(xiàn)只能壓縮 jpg 和 jpeg , 不能壓縮webp
接著找到了 webp-imageio 解決webp , 又發(fā)現(xiàn) 這倆都不支持 png ,
接著找到了 OpenViewerFX 去處理png…

3.2 controller 代碼

我這里自己定死了生產(chǎn)圖片文件夾的路徑 , 各位大神按照自己實(shí)際的需求改動(dòng)

        // 將quality轉(zhuǎn)為 float
        float qualityFloat = Float.parseFloat(quality);

        imageCompressionService.compressImageBySize(inputFile, outputFile,qualityFloat);

        inputFile.delete();

        return "File compressed successfully by size: " + outputFile.getAbsolutePath();
