Java 中jasperReport實(shí)現(xiàn)動(dòng)態(tài)列打印的實(shí)現(xiàn)代碼

        以下代碼中注釋說(shuō)明很清楚,希望能幫助到大家,大家參考下。

示例代碼:

public ActionResult projectPrint() { 
  String[] printValue = null; 
  // 從頁(yè)面中獲得要查詢的字段 
  String reqPrintValue = getRequest().getParameter("printValue"); 
  // 沒(méi)有選擇則默認(rèn)全打印 
  if (null == reqPrintValue || StringUtils.isEmpty(reqPrintValue)) { 
   printValue = new String[] { "pnumber", "pname", "pdepart", "pdecision", "pthrow", "plastmonth", "pfund", "ploan" }; 
  } else { 
   printValue = reqPrintValue.split(","); 
  } 
  // 查詢統(tǒng)計(jì)數(shù)據(jù) 
  List<Object[]> projectList = getEntityManager().queryPrintProjectInfo(printValue); 
 
  // 將數(shù)據(jù)轉(zhuǎn)換為Map對(duì)象,換化成Map對(duì)象 
  List<Map> reportDataList = new ArrayList<Map>();

   Map reportData = new HashMap(); 
   for (int j = 0; j < personStr.length; j++) { 
    reportData.put("field_" + j, String.valueOf(personStr[j])); 
   } 
   reportDataList.add(reportData); 
  } 
 
  int columCount = 0;// 數(shù)據(jù)列 
  int fieldCount = 0;// 字段列數(shù)(因?yàn)閜name比較長(zhǎng)所以想讓pname比其它的列長(zhǎng)些,故設(shè)計(jì)這個(gè)變量)

  for (int i = 0; i < printValue.length; i++) {

   } else if ("ploan".equals(printValue[i])) {
