问题现象：

Java上传图片时，对某些图片进行缩放、裁剪或者生成缩略图时会蒙上一层红色，经过检查只要经过ImageIO.read()方法读取后再保存，该图片便已经变成红图。因此，可以推测直接原因在于ImageIO.read()方法加载图片的过程存在问题。

1 public static BufferedImage getImages(byte[] data) throwsIOException {2 ByteArrayInputStream input = newByteArrayInputStream(data);3 returnImageIO.read(input);4 }

经过查阅得知ImageIO.read()方法读取图片时可能存在不正确处理图片ICC信息的问题，ICC为JPEG图片格式中的一种头部信息，导致渲染图片前景色时蒙上一层红色。

解决方案：

1、使用awt Toolkit

不再使用ImageIO.read()方法加载图片，而使用JDK中提供的Image src=Toolkit.getDefaultToolkit().getImage

Image src = Toolkit.getDefaultToolkit().getImage(file.getPath());

BufferedImage image= BufferedImageBuilder.toBufferedImage(src);//Image to BufferedImage

或者Toolkit.getDefaultToolkit().createImage

1 Image imageTookit =Toolkit.getDefaultToolkit().createImage(bytes);2 BufferedImage cutImage = BufferedImageBuilder.toBufferedImage(imageTookit);

BufferedImageBuilder源码：

public staticBufferedImage toBufferedImage(Image image) {if (image instanceofBufferedImage) {return(BufferedImage) image;

}//This code ensures that all the pixels in the image are loaded

image = newImageIcon(image).getImage();

BufferedImage bimage= null;

GraphicsEnvironment ge=GraphicsEnvironment

.getLocalGraphicsEnvironment();try{int transparency =Transparency.OPAQUE;

GraphicsDevice gs=ge.getDefaultScreenDevice();

GraphicsConfiguration gc=gs.getDefaultConfiguration();

bimage= gc.createCompatibleImage(image.getWidth(null),

image.getHeight(null), transparency);

}catch(HeadlessException e) {//The system does not have a screen

}if (bimage == null) {//Create a buffered image using the default color model

int type =BufferedImage.TYPE_INT_RGB;

bimage= new BufferedImage(image.getWidth(null),

image.getHeight(null), type);

}//Copy image to buffered image

Graphics g =bimage.createGraphics();//Paint the image onto the buffered image

g.drawImage(image, 0, 0, null);

g.dispose();returnbimage;

}

如果该方法在Windows平台下使用正常，而在Linux平台上总是报异常，这种解决方式可以参考：http://blog.csdn.net/shixing_11/article/details/6897871/

2、使用阿里巴巴的SImpleImage

主要依赖以下jar包：commons-io-2.4.jar、commons-lang.jar、commons-logging-1.1.1.jar、jai_codec-1.1.3.jar、jai_core-1.1.3.jar

SimpleImage github地址：https://github.com/alibaba/simpleimage
