同学好，咱们这里主要是在generateThumbnail里面的catch把异常吞了，可以调试一下 看看catch里面报了啥错，我猜应该是水印或者文件不对

  已经解决了仔哥。

  关于这个问题如何解决，我不知道其他的情况，单论我，首先还是debug看一下自己获取的basepath路径的字符串是否是正确的。我获取的路径有三个问题：第一是路径开始多了一个/，我目前还没有深究为什么会多出这个/，知识先将它给除去了；第二个是路径中有空格，上网搜索得知，如果路径有空格，会导致你通过Thread.currentThread().getContextClassLoader().getResource("").getPath()得到的路径，空格会被"%20"代替，所以这肯定是不对的，用replaceAll把这个"%20"替换成" "，第三个就是结尾多出了一个/，这个是个人失误，只要将"/watermark.jpg"的"/"删除就行。
