Question

我无法在Java中读取URL中的图像。在我下载Eclipse Luna并安装Java 8之前，一切都在三四天前工作正常。

try {

    URL url = new URL("some url");
    spriteSheet = ImageIO.read(url);

}catch(IOException e) {

}

System.out.println(spriteSheet);

打印出＆＃39; null＆＃39;，无论我使用什么网址。我的旧项目工作正常，也遇到了同样的问题。但是，我可以从文件中读取图像。有谁知道发生了什么？这是安全设置吗？感谢。

编辑：抱歉!这是堆栈跟踪：
