Description: 查看图片Controller
示例URL：
http://xxx:port/contextPath/image.do?method=showImage&id={fileId|showImageId}&size={Source|Original|Custom}&h={12}&w={35}&handler={handlerName}
http://xxx:port/contextPath/commonimage.do?method=showImage&id={fileId|showImageId}&size={Source|Original|Custom}&h={12}&w={35}&handler={handlerName}
id:表示自定义尺寸，h表示要切图片的高，w表示要切图片的宽
size: custom：表示自定义尺寸，h表示要切图片的高，w表示要切图片的宽、source：图片源文件、original：图片等比压缩后的图片，该图片的高和宽不会变；auto动态自动计算算法(用于大图查看)--尽量让图片小并且不失真
h:要切图的高，只对size=custom有效
w:要切图的宽，只对size=custom有效
handler：如果文件不是通过Id不能从FileManager中获取，则可以通过实行 ImageHandler 来获取图片文件

参数:

request -

response -

抛出:

com.seeyon.ctp.common.exceptions.BusinessException
