开源jxls - java导Excel(多sheet) - 模板文件定义类似jsp的el表达式
想不想像写jsp一样的去定义一个excel模板，然后再像用jstl和el表达式那样往excel模板里面传入变量，现在用jxls全部可以轻松搞定了，核心代码非常简单。
//调用引擎生成excel报表 XLSTransformer transformer = new XLSTransformer(); Workbook workbook = transformer.transformMultipleSheetsList(is, objects, listSheetNames, "list", new HashMap(), 0); workbook.write(new FileOutputStream("c:\\xlsExportUtils.xls"));
下面来看看excel模板是怎么定义的。
是不是和jsp里面的jstl很像。
下面是这个测试例子的完整代码：
