javax.imageio.ImageIO的异常

代码：

String basePath = Thread.currentThread().getContextClassLoader().getResource("").getPath();
Thumbnails.of(new File("C:/test/test.jpg")).size(200, 200).watermark(Positions.BOTTOM_RIGHT,ImageIO.read(new File(basePath + "/watermark.jpg")),0.25f).outputQuality(0.8f).toFile("C:/test/testnew.jpg");

错误信息：

Exception in thread "main" javax.imageio.IIOException: Can't read input file!at javax.imageio.ImageIO.read(Unknown Source)at com.tbx.o2o.util.ImageUtil.main(ImageUtil.java:18)

原因：

路径获取错误

/D:/Javaee%20_workspaces/o2o/target/classes/  
//出现%20的错误

解决方法：

basePath=URLDecoder.decode(basePath,"utf-8");

添加以后：

/D:/Javaee _workspaces/o2o/target/classes/
正常，异常排除
