各位大侠，谁有JAVA报表的源代码，给小弟分享下，没有分了，但是会有别的方式感谢的！谢谢！急！！！
什么格式的报表？
如果是EXCEL的用POI，控制。
PDF的用iText (免费的) svf(付费的)
报表输出成html怎么实现分页
用Jatools打印插件，目前好像都是收费的版本，但我在网上找到个免费的版本就拿来用了，做的练习。
可实现分页，打印。
script type="text/javascript"
function JatoolsPrinterViewPDFReport(page){
var frm = document.getElementById("toolsForm");
var url = "%=webapp %/B1F216Action.do?method=JatoolsPrinterViewPDFReport";
url+="page="+page;
frm.action=url;
frm.target='_self';
frm.submit();
}
function doPrint(how)
{
//打印文档对象
var myDoc = {
documents:document, // 打印页面(div)们在本文档中
copyrights:'杰创软件拥有版权 '
};
// 调用打印方法
if(how == '打印预览...')
jatoolsPrinter.printPreview(myDoc,true ); // 打印预览
else if(how == '打印...')
jatoolsPrinter.print(myDoc ,true); // 打印前弹出打印设置对话框
else
jatoolsPrinter.print(myDoc ,false); // 不弹出对话框打印
}
body style="margin:10px;"
html:form styleId="toolsForm" method="post"
action="/B1F216Action.do?method=JatoolsPrinterViewPDFReport"

后台代码
// 1.html显示
JRHtmlExporter exporter = new JRHtmlExporter();
//设置导出参数
request.getSession().setAttribute( BaseHttpServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, jasperPrint);
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out);
exporter.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN, Boolean.FALSE);//页面显示图片为X，可设置false
exporter.setParameter(JRExporterParameter.CHARACTER_ENCODING, "GBK");
int pageIndex = 0;
int lastPageIndex = 0;
if (jasperPrint.getPages() != null)
{
lastPageIndex = jasperPrint.getPages().size() - 1;
}
String pageStr = request.getParameter("page");
try
{
pageIndex = Integer.parseInt(pageStr);
}
catch(Exception e)
{
}
if (pageIndex 0)
{
pageIndex = 0;
}
if (pageIndex lastPageIndex)
{
pageIndex = lastPageIndex;
}
StringBuffer sbuffer = new StringBuffer();
exporter.setParameter(JRExporterParameter.PAGE_INDEX, Integer.valueOf(pageIndex));
exporter.setParameter(JRHtmlExporterParameter.HTML_HEADER, "");
exporter.setParameter(JRHtmlExporterParameter.BETWEEN_PAGES_HTML, "");
exporter.setParameter(JRHtmlExporterParameter.HTML_FOOTER, "");
exporter.setParameter(JRExporterParameter.OUTPUT_STRING_BUFFER, sbuffer);
request.setAttribute("pageIndex", pageIndex);
request.setAttribute("lastPageIndex", lastPageIndex);
request.setAttribute("sbuffer", sbuffer);
//此处就是html导出方式，打印部分在页面通过插件实现
exporter.exportReport();
