继上次report的demo后，还在继续做着report方面的research，今天主要是实现了通过javabean datasource填充chart图表，通过webservice下载pdf格式的报表。

       开始这一段快乐之旅吧，首先我在包下定义了两个类分别是Student和Mark，Student类下有三个属性，他们分别是

 

private String name;private String number;private List mark;

Mark类下定义了两个属性

 

 

private String name;private double mark;

另外写了一个函数去获取student的列表List，这将是填充JavaBean的数据源

 

 

public List
    
      getBeanData(){		List
     
       listStudent = new ArrayList
      
       ();		Student student = new Student();		student.setName("cheng");		student.setNumber("01");				List
        listMark = new ArrayList();		listMark.add(new Mark("销售", 100));		listMark.add(new Mark("IT", 139));		listMark.add(new Mark("s", 110.6));		listMark.add(new Mark("d", 120.4));		listMark.add(new Mark("e", 120));				student.setMark(listMark);		listStudent.add(student);		return listStudent;	}
      
     
    

设计report chart报表

 

最后的任务是写webservice,打印出报表，贴主要的代码实现，有一些函数在上一篇文章中已经实现

 

public List
    
      getBeanData(){		List
     
       listStudent = new ArrayList
      
       ();		Student student = new Student();		student.setName("cheng");		student.setNumber("01");				List
        listMark = new ArrayList();		listMark.add(new Mark("销售", 100));		listMark.add(new Mark("IT", 139));		listMark.add(new Mark("s", 110.6));		listMark.add(new Mark("d", 120.4));		listMark.add(new Mark("e", 120));				student.setMark(listMark);		listStudent.add(student);		return listStudent;	}		//javabean	@Path("download/chart")	@Produces(MediaType.TEXT_PLAIN)	@Transactional	public String downloadReportByJavaBean(@Context HttpServletRequest req , @Context HttpServletResponse res) throws Exception{		String designFilePath = req.getSession().getServletContext().getRealPath("/jasper") + 				File.separator + "chartreport.jrxml";		File designFile = new File(designFilePath);				if(designFile.exists()){			JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(getBeanData());			JasperReport jasperReport = null;			JasperDesign design = JRXmlLoader.load(designFile);			jasperReport = JasperCompileManager.compileReport(design);						JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,null,dataSource);			XLSReportProcess process = new XLSReportProcess();			process.exportWebReport(ReportProcess.Type.pdf, res, jasperPrint , "chart.pdf");					}		return "success";	}
      
     
    

最后实现的效果是通过webservice自动下载pdf文档，内容显示
