问题描述
我有一个 .jp2 图像文件，我想将其转换为 .jpg.
I have a .jp2 image file that I want to convert to .jpg.
BufferedImage background = ImageIO.read(new File("images\\"
+ randNum + ".jp2"));
ImageIO.write(background, "jpg", new File("images\\" + randNum
+ ".jpg"));
我有这个例外:
java.util.ServiceConfigurationError: javax.imageio.spi.ImageWriterSpi: Provider com.github.jaiimageio.jpeg2000.impl.J2KImageWriterSpi could not be instantiated
...
Caused by: java.lang.NoClassDefFoundError: com/github/jaiimageio/impl/common/PackageUtil
...
Caused by: java.lang.ClassNotFoundException: com.github.jaiimageio.impl.common.PackageUtil
推荐答案
显然发生了冲突，我使用的是来自不同库的类，这里我有 jai_imageio 和 jai-imageio-jpeg2000，我通过简单地删除其中一个来解决这个问题.
Apparently, a conflict occured, I was using classes from different libraries, here I had both jai_imageio and jai-imageio-jpeg2000, I solved this problem by simply removing one of them.
