实现java导入excel文件的例子,在做的过程中如果出现Workbook打不开，请更换jxl版本，尽量用低版本，这样与jdk兼容会好点，我在做这个导入excel的时候，就遇到了版本兼容问题，处理了半天才发现问题所在。所以想做这个例子给大家参考，以后不要犯和我同样的错误。-Examples of java achieve import excel file, in the process of doing Workbook if not open, replace jxl version, try to use low version, so compatible with jdk be a good point, I' m doing this import excel when they encountered version compatibility issues to deal with for a long time only to find the problem. So want this example for your reference, this will not make me the same error.
