方法代码：

ClassLoader loader = Thread.currentThread().getContextClassLoader();InputStream flagInputStream = loader.getResourceAsStream("static/imagesLogo/imageaaa.png");BufferedImage read;read = ImageIO.read(flagInputStream);System.out.println("测试读取图片" + read);InputStream resourceAsStream = LectureMessageServiceImpl.class.getClassLoader().getResourceAsStream("static/imagesLogo/imageaaa.png");BufferedImage read2;read2 = ImageIO.read(resourceAsStream);System.out.println("测试读取图片" + read2);
