IReport配合pdfjs或者pdfObject预览打印pdf

pdf JS javascript IReport

弄了好些天终于把IReport配合pdfjs(html5编写的，兼容ie9+)或者pdfObjec(能兼容ie7+,但是Chrome,FireFox兼容不好)预览打印pdf的功能了，简单总结如下：

存在子报表的.jrxml无法通过工具ireport-designer工具生成的，应该怎么转换成.jasper？只有通过调用原生态的 JasperCompileManager.compileReportToFile 方法下可以转换

 public static void main(String[] args) {
        try {
            JasperCompileManager.compileReportToFile
                    ("E:\\work\\workspace\\bssspace\\ctg-itrdc\\ctg-itrdc-order\\ctg-itrdc-order-service\\src\\main" +
                                    "\\resources\\jasper\\template\\report1_main.jrxml",
                            "E:\\work\\workspace\\bssspace\\ctg-itrdc\\ctg-itrdc-order\\ctg-itrdc-order-service\\src" +
                                    "\\main\\resources\\jasper\\template\\report1_main.jasper");
            JasperCompileManager.compileReportToFile
                    ("E:\\work\\workspace\\bssspace\\ctg-itrdc\\ctg-itrdc-order\\ctg-itrdc-order-service\\src\\main" +
                                    "\\resources\\jasper\\template\\report_new_subreport1.jrxml",
                            "E:\\work\\workspace\\bssspace\\ctg-itrdc\\ctg-itrdc-order\\ctg-itrdc-order-service\\src" +
                                    "\\main\\resources\\jasper\\template\\report_new_subreport1.jasper");
        } catch (JRException e) {
            e.printStackTrace();
        }
    }

相对应的pdfjs和pdfObjecr，请查看附件上传
由于pdfjs是html5编写的第三方插件，所以不用借助PDFreader展示只需要在viewer.html加入：

<script type="text/javascript" src="../js/jquery/1.8.0/jquery-1.8.0.min.js"></script>
<script type="text/javascript" src="../js/pdfjs/compatibility.js"></script>
<link rel="resource" type="application/l10n" href="../js/pdfjs/viewer.properties"/>
<script type="text/javascript" src="../js/pdfjs/l10n.js"></script>
<script src="../js/pdfjs/viewer.js"></script>
<script src="../js/pdfjs/build/pdf.js"></script>
<script src="../js/pdfjs/debugger.js"></script>
<link rel="stylesheet" type="text/css" href="../js/pdfjs/viewer.css" />
<script type="text/javascript">

	var DEFAULT_URL = contextPath + "/receipt/outPutStream?custOrderId=100";//application/pdf类型
</script>

把相对应的 viewer.js中的

var DEFAULT_URL = 'compressed.tracemonkey-pldi-09.pdf'; 替换掉

如果是使用pdfObject的话，相对应的js的如下

<script src="<%=contextPath%>/js/pdfobject.js" type="text/javascript"></script>
<script type="text/javascript">
$(function(){
	
	//设置PDF文件的URL地址
// 	var pdfUrl = contextPath+"/modules/order/receipt/SpringMVC.pdf";//application/pdf类型
	
	var pdfUrl = contextPath+"/receipt/outPutStream?orderId=100";//application/pdf类型
//  	var pdfUrl = contextPath+"/receipt/exportPdf?orderId=100";//application/pdf类型
	//设置PDF预览DIV的长度和宽度
	var w = $(document).width();
	var h = $(document).height();
	$("#pdfDiv").css("width", w).css("height", h);

	//构造PDF对象
	var pdfObj = new PDFObject({ url: pdfUrl,	
		pdfOpenParams: {
		navpanes: 1,
		view: "FitV",
		pagemode: "thumbs"
	}
});
	var obj = pdfObj.embed("pdfDiv");
    if (!obj) {
//     	if(pdfObj.hasReaderActiveX()) {
			$('#pdfDiv').hide();
			window.location = pdfUrl;
//     	}
	};
})
</script>
</head>
<body>
  <div id="pdfDiv" >对不起,您还没有安装PDF阅读器软件呢,为了方便预览PDF文档,请选择安装！下载地址：
  <a href="http://dlsw.baidu.com/sw-search-sp/soft/31/12612/AdbeRdr11000_zh_CN11.0.0.379.1410747856.exe">AdbeRdr</a>安装后请重启</div>	
</body>

静态文件替换成后台输出的outputstream的字节流即可；如下

   /**
     * 输出pdf
     * @return
     */
    @RequestMapping("/outPutStream")
    @ResponseBody
    public void outPutStream(HttpServletRequest request, HttpServletResponse response) {
        OutputStream outputStream = null;
        try {
            outputStream = response.getOutputStream();
            response.setContentType("application/pdf;charset=UTF-8");
            String orderId = request.getParameter("orderId");
            System.out.println("orderID:" + orderId);
            String fileName = System.currentTimeMillis() + ".pdf";
            response.setHeader("Content-Disposition", "attachment; filename=" + fileName);
            Map<String, Object> paramMap = new HashMap<>();
            byte[] data = new byte[4096];
            JRDataSource jrDataSource = new JRBeanCollectionDataSource(JavaBeanPerson.getList());
            InputStream inputStream = getClass().getResourceAsStream("/jasper/template/spring_report.jasper");
            JasperReport jasperReport = (JasperReport) JRLoader.loadObject(inputStream);
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, paramMap, jrDataSource);
            data = JasperExportManager.exportReportToPdf(jasperPrint);
            outputStream.write(data);
            outputStream.flush();
        } catch (Exception ex) {
            logger.error("生成回执流异常", ex);
            ex.printStackTrace();
        } finally {
            try {
                outputStream.close();
            } catch (IOException e) {
                logger.error("文件流关闭异常", e);
                e.printStackTrace();
            }
        }
    }

中间填充数据的时候需要2个jar包 iTextAsian.jar iText-5.0.5.jar 可以查看附件下载；

spring_report.jrxml spring_report.jasper 查看附件receipt_jasper.rar下载
