javax.imageio.IIOException: Can't read input file!完美解决

路径名导致的异常：javax.imageio.IIOException: Can't read input file!

背景: 写了一个测试程序,目的是读取本地的图片,为其打上水印图片.在使用过程中总会遇到:javax.imageio.IIOException: Can't read input file!的错误,最开始以为是图片路径名称写的不对,按照网上的提示换成正斜线和反斜线都不行.后来发现问题的原因是:图片的路径中不能有点(英文点:.); 具体的错误异常提示如下: javax.imageio.IIOException: Can't read input file! at javax.imageio.Imag
