我在我的项目中使用struts和jasper报告,现在我遇到问题,每当我尝试打印报告时,打印机对话框出现在服务器机器上,我希望它在客户端而不导出任何格式的报告
答案 0 :(得分:2)
我尝试了以下代码镫骨,它对我来说很好。
第1步: 在基础Jsp(report.jsp)
input type =“hidden”name =“contextPath”value =“<%= request.getContextPath()%>” ID = “contextPath中”/>
第2步: 在includesed js(report.js)
var contextPath=document.getElementById("contextPath").value;
var url=contextPath+"/generateRecptReport.do?method=generateRecptReport;
popupWin= window.open(url,'Report','menubar, toolbar, location, directories, status, scrollbars, resizable, dependent, width=1, height=1 left=0, top=0');
第3步 在struts-config.xml文件
<action path="/generateRecptReport" scope="request" parameter="method" type="com.cm.actions.ReceiptMakerProcessAction">
</action>
* *第4步 on Action(Java代码)(ReceiptMakerProcessAction.java)
public ActionForward generateRecptReport(ActionMapping mapping,ActionForm form, HttpServletRequest request,HttpServletResponse response) throws Exception
{
logger.info("In generateRecptReport");
String p_company_logo=getServlet().getServletContext().getRealPath("/")+"reports/logo.bmp";
String reportPath="/reports/MSSQLREPORTS/";
String reportName="receiptMemoReport";
ReportsDAO reportdao = (ReportsDAO)DaoImplInstanceFactory.getDaoImplInstance(ReportsDAO.IDENTITY);
logger.info("Implementation class: "+reportdao.getClass());
reportName=reportdao.getReceiptReportName();
if(CommonFunction.checkNull(reportName).trim().equalsIgnoreCase(""))
reportName="receiptMemoReport";
Connection connectDatabase = ConnectionDAO.getConnection();
Map<Object,Object> hashMap = new HashMap<Object,Object>();
hashMap.put("p_company_logo",p_company_logo);
hashMap.put("IS_IGNORE_PAGINATION",true);
try
{
InputStream reportStream = getServlet().getServletConfig().getServletContext().getResourceAsStream(reportPath+reportName+".jasper");
JasperPrint jasperPrint = null;
PrintWriter out=response.getWriter();
out.append("<head><script type='text/javascript' src='"+request.getContextPath()+"/js/report/report.js'></script></head>");
out.append("<body onLoad='self.print();self.close()'></body>");
response.setContentType("text/html");
String htmlReportFileName=reportName+".html";
JRHtmlExporter exporter = new JRHtmlExporter();
request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE,jasperPrint);
exporter.setParameter(JRHtmlExporterParameter.OUTPUT_WRITER, out);
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN ,Boolean.FALSE);
exporter.setParameter(JRHtmlExporterParameter.IGNORE_PAGE_MARGINS ,Boolean.TRUE);
exporter.setParameter(JRHtmlExporterParameter.IS_WHITE_PAGE_BACKGROUND,Boolean.FALSE);
exporter.setParameter(JRHtmlExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS,Boolean.TRUE);
exporter.setParameter(JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR, Boolean.TRUE);
exporter.setParameter(JRHtmlExporterParameter.BETWEEN_PAGES_HTML,"");
exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, response.getWriter());
float f1=1.2f;
exporter.setParameter(JRHtmlExporterParameter.ZOOM_RATIO ,f1);
exporter.exportReport();
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
ConnectionDAO.closeConnection(connectDatabase, null);
hashMap.clear();
}
return null;
}
希望在没有生成报告的情况下对客户端的Jasper报告打印有帮助
