**一、简单介绍**  
这里使用的工具是ireport-5.6.0来制作报表模板，内容主要有报表中如何遍历数据，报表与报表之间如何传值。  
**二、报表设计图**

1.  主报表  
    ![在这里插入图片描述][70]  
    说明：主报表包括两部分：头部（Title）、循环体（Detail1）；这里将Detail1的内容放到了二级报表中，如下所示：
2.  二级报表  
    ![在这里插入图片描述][70 1]  
    说明：同样二级报表循环体也嵌套了一个三级报表，如下：
3.  三级报表  
    ![在这里插入图片描述][70 2]  
    **三、后台代码**  
    1、在控制类里面创建工具类（ProductTraceController内部类）  
    （1）、第一层循环的工具类
    
        public class Product_iReport{
        private String productno;
        private String partsno;
        private String partsname;
        private  List<Process_iReport> twoiReport;
        public String getProductno() {
        	return productno;
        }
        public void setProductno(String productno) {
        	this.productno = productno;
        }
        public String getPartsno() {
        	return partsno;
        }
        public void setPartsno(String partsno) {
        	this.partsno = partsno;
        }
        public String getPartsname() {
        	return partsname;
        }
        public void setPartsname(String partsname) {
        	this.partsname = partsname;
        }
        public List<Process_iReport> getTwoiReport() {
        	return twoiReport;
        }
        public void setTwoiReport(List<Process_iReport> twoiReport) {
        	this.twoiReport = twoiReport;
        }
        
        }

（2）、第二层循环的工具类(ProductTraceController内部类)

public class Process_iReport{
    	private  String processno;
    	private  String processname;
    	private  List<SubreportClass> measureList;
    	public String getProcessno() {
    		return processno;
    	}
    	public void setProcessno(String processno) {
    		this.processno = processno;
    	}
    	public String getProcessname() {
    		return processname;
    	}
    	public void setProcessname(String processname) {
    		this.processname = processname;
    	}
    	public List<SubreportClass> getMeasureList() {
    		return measureList;
    	}
    	public void setMeasureList(List<SubreportClass> measureList) {
    		this.measureList = measureList;
    	}
    }

（3）、第三层循环的工具类（ProductTraceController内部类）

public class SubreportClass{
    	private String itemNo;        //序号
    	private String itemName;      //项目名称
    	private String testValue;     //实测值
    	private String normalValue;   //名义值
    	private String uslValue;      //上公差
    	private String lslValue; 	  //下公差
    	private String deviation;     //偏差
    	private String evaluate;      //评定
    	private String toolsNo;       //器具编号
    	private String toolsName;     //器具名称
    	private String measureMan;    //测量人
    	private String measureTime;   //测量时间
    	public String getItemNo() {
    		return itemNo;
    	}
    	public void setItemNo(String itemNo) {
    		this.itemNo = itemNo;
    	}
    	public String getItemName() {
    		return itemName;
    	}
    	public void setItemName(String itemName) {
    		this.itemName = itemName;
    	}
    	public String getTestValue() {
    		return testValue;
    	}
    	public void setTestValue(String testValue) {
    		this.testValue = testValue;
    	}
    	public String getNormalValue() {
    		return normalValue;
    	}
    	public void setNormalValue(String normalValue) {
    		this.normalValue = normalValue;
    	}
    	public String getUslValue() {
    		return uslValue;
    	}
    	public void setUslValue(String uslValue) {
    		this.uslValue = uslValue;
    	}
    	public String getLslValue() {
    		return lslValue;
    	}
    	public void setLslValue(String lslValue) {
    		this.lslValue = lslValue;
    	}
    	public String getDeviation() {
    		return deviation;
    	}
    	public void setDeviation(String deviation) {
    		this.deviation = deviation;
    	}
    	public String getEvaluate() {
    		return evaluate;
    	}
    	public void setEvaluate(String evaluate) {
    		this.evaluate = evaluate;
    	}
    	public String getToolsNo() {
    		return toolsNo;
    	}
    	public void setToolsNo(String toolsNo) {
    		this.toolsNo = toolsNo;
    	}
    	public String getToolsName() {
    		return toolsName;
    	}
    	public void setToolsName(String toolsName) {
    		this.toolsName = toolsName;
    	}
    	public String getMeasureMan() {
    		return measureMan;
    	}
    	public void setMeasureMan(String measureMan) {
    		this.measureMan = measureMan;
    	}
    	public String getMeasureTime() {
    		return measureTime;
    	}
    	public void setMeasureTime(String measureTime) {
    		this.measureTime = measureTime;
    	} 
    }

2、获取获取全部树形表格中的值—产品报告模板，对应接口如下：

@RequestMapping(value = {"ReportProductList-{grano}@{ProductSerielno}@{workPieceNum}@{TmpSelectedParentId}@{ProductName}"}, method = RequestMethod.GET)
    @ResponseBody
    public void ReportProductList(@PathVariable(value = "grano") String grano,@PathVariable(value = "ProductSerielno") String 
    		ProductSerielno,@PathVariable(value = "workPieceNum") String workPieceNum,@PathVariable(value = "TmpSelectedParentId") String TmpSelectedParentId,
    		@PathVariable(value = "ProductName") String ProductName,
    		HttpServletResponse response,HttpServletRequest request) throws JRException, IOException 
    { 
    	String path = System.getProperty("emrpwebapp.root") + "\\jasperreports\\";
    	// 避免路径中出现转译字符
    	try {
    		path = java.net.URLDecoder.decode(path, "utf-8");
    	} catch (UnsupportedEncodingException e) {
    		 
    		e.printStackTrace();
    	}
    	Map<String, Object> parameters = new HashMap<String, Object>();
    	parameters.put("ReportLogo", path + "image\\ReportLogo.jpg");
    	parameters.put("Title", "西安");
    	parameters.put("SubTitle", "德翼测量软件有限公司");
    	
    	parameters.put("SUBREPORT_DIR", path);
    	
    	/***标签**/
    	parameters.put("ProductNoTag", "工件编号");
    	parameters.put("ProgramNoTag", "产品代号");
        parameters.put("ProductNameTag","产品名称");
        parameters.put("PartsNumTag", "零部件代号");
        parameters.put("PartsNameTag", "零部件名称");
        parameters.put("Empty", "");
        
        /**通用值**/
        parameters.put("ProgramNo", grano);
        parameters.put("ProductName", ProductName);
        
        
        /**遍历二级报表-表头标签***/
        Map<String, Object> subreportMap = new HashMap<String, Object>();
        subreportMap.put("SUBREPORT_DIR", path);
        subreportMap.put("ProcessNoTag", "工序编号：");
        subreportMap.put("ProcessNameTag", "工序名称：");
        /**循环遍历表数据***/
        subreportMap.put("ItemNoTag", "编号");//编号
        subreportMap.put("ItemNameTag","项目名称");
        subreportMap.put("TestValueTag", "实测值"); 
        subreportMap.put("NormalValueTag", "名义值");
        subreportMap.put("UslValueTag", "上公差"); 
        subreportMap.put("LslValueTag", "下公差"); 
        subreportMap.put("DeviationTag", "偏差");
        subreportMap.put("EvaluateTag", "评定"); 
        subreportMap.put("ToolsNoTag", "器具编号");
        subreportMap.put("ToolsNameTag", "器具名称");
        subreportMap.put("MeasureManTag", "测量人");
        subreportMap.put("MeasureTimeTag", "测量时间");
        
        parameters.put("TwoSubreport", subreportMap);
        
    	JSONArray jsonPrdLists= ResultQuery(grano,ProductSerielno,workPieceNum,TmpSelectedParentId);
    	 List<Product_iReport> lst=new ArrayList<Product_iReport>();//一级主表
    	for(int a=0;a<jsonPrdLists.size();a++){
    		JSONObject jo=jsonPrdLists.getJSONObject(a);
    		Product_iReport pi=new Product_iReport();
    		pi.setProductno(jo.getString("workPieceNum"));
    		pi.setPartsno(jo.getString("productnum"));
    		pi.setPartsname(jo.getString("productname"));
    		String pid=jo.getString("id");
    		List<Process_iReport> prList=iReport_ListValue(pid,jo.getString("workPieceNum"));
    		pi.setTwoiReport(prList); 
    		lst.add(pi);
    	}
    	FileInputStream jasperStream = new FileInputStream(path + "/rpt_ReportProductList.jasper");
    
    	JasperReport jasperReport = (JasperReport) JRLoader.loadObject(jasperStream);
    	
    	JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters,
    			new JRBeanCollectionDataSource(lst));
    	
    	response.setContentType("application/pdf");
    	response.setHeader("Content-disposition", "inline; filename=ReportProductList.pdf");
    	final OutputStream outStream = response.getOutputStream();
    	JasperExportManager.exportReportToPdfStream(jasperPrint, outStream);
    }

3、上面三层循环报表中进行值传递的方法是：  
①、首先将下层报表的值放到map集合中，java代码如下：

Map<String, Object> subreportMap = new HashMap<String, Object>();
        subreportMap.put("SUBREPORT_DIR", path);
        subreportMap.put("ProcessNoTag", "工序编号：");
        subreportMap.put("ProcessNameTag", "工序名称：");
        /**循环遍历表数据***/
        subreportMap.put("ItemNoTag", "编号");//编号
        subreportMap.put("ItemNameTag","项目名称");
        subreportMap.put("TestValueTag", "实测值"); 
        subreportMap.put("NormalValueTag", "名义值");
        subreportMap.put("UslValueTag", "上公差"); 
        subreportMap.put("LslValueTag", "下公差"); 
        subreportMap.put("DeviationTag", "偏差");
        subreportMap.put("EvaluateTag", "评定"); 
        subreportMap.put("ToolsNoTag", "器具编号");
        subreportMap.put("ToolsNameTag", "器具名称");
        subreportMap.put("MeasureManTag", "测量人");
        subreportMap.put("MeasureTimeTag", "测量时间");
       
        /**parameters是一个Map集合，存放主报表表头参数，这里将二级报表的表头参数
        首先放到一个Map集合里，然后将二级报表表头参数的map集合subreportMap放到
        主报表的parameters集合中**/
        parameters.put("TwoSubreport", subreportMap);

②，给二级传递参数不但要在java代码中进行处理，在ireport中也要进行处理（如图）  
![在这里插入图片描述][70 3]  
a、如①所标注的地方为要传递给二级报表的参数  
b、详见下图：  
![在这里插入图片描述][70 4]  
里面的配置为：

new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{twoiReport})

③、二级报表如图所示：  
![在这里插入图片描述][70 5]  
④、到这里后台和ireport的准备工作全部完成，来看web显示部分：

4、《补充》只有两层嵌套报表的接口对应如下：  
/**获取树形表格中单个的值—零部件报告模板**/

@RequestMapping(value = { "ReportProcessList-{rowid}@{workPieceNum}@{ProductName}"}, method = RequestMethod.GET)
    @ResponseBody
    public void ReportProcessList(@PathVariable(value = "rowid") String rowid,@PathVariable(value = "workPieceNum") String workPieceNum,@PathVariable(value = "ProductName") String ProductName,
    		HttpServletResponse response,HttpServletRequest request) throws JRException, IOException 
    { 
    	Productview pv=prdViewServ.findById(rowid);
    	
    	String path = System.getProperty("emrpwebapp.root") + "\\jasperreports\\";
    	// 避免路径中出现转译字符
    	try {
    		path = java.net.URLDecoder.decode(path, "utf-8");
    	} catch (UnsupportedEncodingException e) {
    		 
    		e.printStackTrace();
    	}
    	
    	
    	Map<String, Object> parameters = new HashMap<String, Object>();
    	parameters.put("ReportLogo", path + "image\\ReportLogo.jpg");
    	parameters.put("Title", "西安");
    	parameters.put("SubTitle", "德翼测量软件有限公司");
    	
    	parameters.put("SUBREPORT_DIR", path);
    	
    	/***标签**/
    	parameters.put("ProductNoTag", "工件编号");
    	parameters.put("ProgramNoTag", "产品代号");
        parameters.put("ProductNameTag","产品名称");
        parameters.put("PartsNumTag", "零部件代号");
        parameters.put("PartsNameTag", "零部件名称");
        
        /****值****/
        parameters.put("ProductNo", workPieceNum);
        parameters.put("ProgramNo", pv.getGrano());
        parameters.put("ProductName", ProductName);
        parameters.put("Partsnum", pv.getProductnum());
        parameters.put("PartstName", pv.getProductname());
        parameters.put("Empty", "");
        
    	/**遍历表头标签***/
        parameters.put("ProcessNoTag", "工序编号：");
        parameters.put("ProcessNameTag", "工序名称：");
        /**循环遍历表数据***/
        parameters.put("ItemNoTag", "编号");//编号
        parameters.put("ItemNameTag","项目名称");
        parameters.put("TestValueTag", "实测值"); 
        parameters.put("NormalValueTag", "名义值");
        parameters.put("UslValueTag", "上公差"); 
        parameters.put("LslValueTag", "下公差"); 
        parameters.put("DeviationTag", "偏差");
    	parameters.put("EvaluateTag", "评定"); 
    	parameters.put("ToolsNoTag", "器具编号");
    	parameters.put("ToolsNameTag", "器具名称");
    	parameters.put("MeasureManTag", "测量人");
    	parameters.put("MeasureTimeTag", "测量时间");
        
        List<Process_iReport> lst=iReport_ListValue(rowid,workPieceNum);//主表
       
    	FileInputStream jasperStream = new FileInputStream(path + "/rpt_ReportProcessList.jasper");
    
    	JasperReport jasperReport = (JasperReport) JRLoader.loadObject(jasperStream);
    	
    	JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters,
    			new JRBeanCollectionDataSource(lst));
    	
    	response.setContentType("application/pdf");
    	response.setHeader("Content-disposition", "inline; filename=rpt_ReportProcessList.pdf");
    	final OutputStream outStream = response.getOutputStream();
    	JasperExportManager.exportReportToPdfStream(jasperPrint, outStream);
    
    }
