jxls

Question

我正在尝试使用 jxls 库创建 excel 表单。

我的 excel 模板是：

当我将一张地图添加到列表中并绑定它时，它起作用了。我的代码很简单：

List<Map<String,Object>> sss = new ArrayList();

HashMap<String,Object> sm = new HashMap<String,Object>();
sm.put("name1", "AtestName");
sm.put("name2", "AtestName2");
sm.put("name3", "AtestName3");
sss.add(sm);

Map<String, Object> model = new HashMap<String,Object>();
model.put("sData", sss);
....  XLSTransformer transformer = new XLSTransformer(); .....

但是当我将多个地图添加到列表并绑定它时，它无法抛出异常。听说jxls库自动识别列表。我在做什么？

List<Map<String,Object>> sss = new ArrayList();
HashMap<String,Object> sm = new HashMap<String,Object>();
sm.put("name1", "AtestName");
sm.put("name2", "AtestName2");
sm.put("name3", "AtestName3");
sss.add(sm);

HashMap<String,Object> sm2 = new HashMap<String,Object>();
sm.put("name1", "BtestName");
sm.put("name2", "BtestName2");
sm.put("name3", "BtestName3");
sss.add(sm2);

HashMap<String,Object> sm3 = new HashMap<String,Object>();
sm.put("name1", "CtestName");
sm.put("name2", "CtestName2");
sm.put("name3", "CtestName3");
sss.add(sm3);

Map<String, Object> model = new HashMap<String,Object>();
model.put("sData", sss);
....  XLSTransformer transformer = new XLSTransformer(); .....

Answer 1

您收到的错误 java.lang.NoSuchMethodError:org.apache.poi.ss.usermodel.Sheet.getSheetConditionalFormatting 很可能意味着您的 POI 版本有问题。

所以请检查您使用的 Apache POI 版本以及它是否支持 Sheet.getSheetConditionalFormatting() 方法

jxls - 多行（列表）绑定不起作用

jxls - multiple row (list) binding doesn't work
