jxls -多行(列表)绑定无效

Question

我正在尝试使用jxls库创建excel表单。

我的excel模板是：

​

​

当我只添加一张地图来列出并绑定它时，它就能工作了。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，当我添加多个映射来列出并绑定它时，它将失败抛出异常。我听说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

您得到的java.lang.NoSuchMethodError:org.apache.poi.ss.usermodel.Sheet.getSheetConditionalFormatting错误很可能意味着POI版本有问题。

因此，请检查您使用的Apache版本，以及它是否支持Sheet.getSheetConditionalFormatting()方法。
