Java中jasperReport实现动态列打印的实现代码
以下代码中注释说明很清楚，希望能帮助到大家，大家参考下。
示例代码：
publicActionResultprojectPrint(){
String[]printValue=null;
//从页面中获得要查询的字段
StringreqPrintValue=getRequest().getParameter("printValue");
//没有选择则默认全打印
if(null==reqPrintValue||StringUtils.isEmpty(reqPrintValue)){
printValue=newString[]{"pnumber","pname","pdepart","pdecision","pthrow","plastmonth","pfund","ploan"};
}else{
printValue=reqPrintValue.split(",");
}
//查询统计数据
ListprojectList=getEntityManager().queryPrintProjectInfo(printValue);

//将数据转换为Map对象，换化成Map对象
ListreportDataList=newArrayList();

for(inti=0;ipageCountList=newArrayList();
Object[]obj=newString[]{"合计","15299","","","67121","92420","155877",};
pageCountList.add(obj);
obj=newString[]{"","","","XXX小计","","24473","16470",};
pageCountList.add(obj);
obj=newString[]{"","","","WWW小计","","7289","1674",};
pageCountList.add(obj);
obj=newString[]{"","","","ZZZ小计","","32700","13000",};
pageCountList.add(obj);
obj=newString[]{"","","","YYY小计","","12733","120733",};
pageCountList.add(obj);
obj=newString[]{"","","","AAA小计","","2225","120733",};
pageCountList.add(obj);
obj=newString[]{"","","","BBB小计","","3000","0",};
pageCountList.add(obj);
