java 本地打印docflavor java打印模版

 

• 通过iText打印pdf文档

1 导入jar包

<dependency>
            <groupId>com.lowagie</groupId>
            <artifactId>itext</artifactId>
            <version>2.1.7</version>
        </dependency>

2  详细代码段

Document document = new Document();
            PdfWriter.getInstance(document,new FileOutputStream("F:\\test.pdf"));
            document.open();
            document.add(new Paragraph("hello itext"));
            document.close();

 

• 通过jasperreport和模板设计器jaspersort studio答应pdf文档

jasperreport的底层也是itext，jasperreport需要jrxml模板。jrxml模板可以由jaspersort studio生成。

1 导入jar包

<dependency>
            <groupId>net.sf.jasperreports</groupId>
            <artifactId>jasperreports</artifactId>
            <version>6.8.0</version>
        </dependency>

1. 详细代码段

String jrxmlPath ="F:\\Users\\lin\\IdeaProjects\\gitdemo1\\health_parent\\itext\\src\\main\\resources\\demo.jrxml";
        String jasperPath = "F:\\Users\\lin\\IdeaProjects\\gitdemo1\\health_parent\\itext\\src\\main\\resources\\demo.jasper";

        JasperCompileManager.compileReportToFile(jrxmlPath,jasperPath);

        Map paramter = new HashMap();
        paramter.put("reportDate","2019-10-10");
        paramter.put("company","itcast");

        List<Map> list = new ArrayList<>();
        Map map1 = new HashMap();
        map1.put("name","xiaoming");
        map1.put("address","beijing");
        map1.put("email","[e-mail]");
        Map map2 = new HashMap();
        map2.put("name","xiaoli");
        map2.put("address","nanjing");
        map2.put("email","[e-mail]");
        list.add(map1);
        list.add(map2);

        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperPath,paramter,new JRBeanCollectionDataSource(list));

        String pdfPath = "f:\\test.pdf";
        JasperExportManager.exportReportToPdfFile(jasperPrint,pdfPath);

 

• 介绍jaspersort studio

1. jdbc数据源式填充数据

在

在driver classpath中加载数据驱动，然后点击测试。

然后右击test1 选择databaseandquery 点击确定。之后可以在fields里拖拽变量。

//jrxmll 路径
        String jrxmlPath ="F:\\Users\\lin\\IdeaProjects\\gitdemo1\\health_parent\\itext\\src\\main\\resources\\demo3.jrxml";
        //生成的jasper文件的路径
        String jasperPath = "F:\\Users\\lin\\IdeaProjects\\gitdemo1\\health_parent\\itext\\src\\main\\resources\\demo.jasper";
        //把jrxmll编译成jasper文件
        JasperCompileManager.compileReportToFile(jrxmlPath,jasperPath);
        //需要提供mysql的连接
        Connection connection = connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/health","root","root");
            JasperPrint jasperPrint = null;
            //数据填充
            jasperPrint = JasperFillManager.fillReport (jasperPath,null,connection);
            //目标pdf的路径
            String pdfPath = "f:\\test.pdf";
            //打印pdf
            JasperExportManager.exportReportToPdfFile(jasperPrint,pdfPath);

1. javabean数据源式填充数据

在field新建，然后拖拽，详细java代码

String jrxmlPath ="F:\\Users\\lin\\IdeaProjects\\gitdemo1\\health_parent\\itext\\src\\main\\resources\\demo2.jrxml";
        String jasperPath = "F:\\Users\\lin\\IdeaProjects\\gitdemo1\\health_parent\\itext\\src\\main\\resources\\demo.jasper";
        JasperCompileManager.compileReportToFile(jrxmlPath,jasperPath);

        Map paramter = new HashMap();

        List<Map> list = new ArrayList<>();
        Map map1 = new HashMap();
        map1.put("id",1L);
        map1.put("name","tianyi");

        Map map2 = new HashMap();
        map1.put("id",2L);
        map1.put("name","lier");

        list.add(map1);
        list.add(map2);

        JasperPrint jasperPrint = JasperFillManager.fillReport (jasperPath,paramter,new JRBeanCollectionDataSource(list));

        String pdfPath = "f:\\test.pdf";
        JasperExportManager.exportReportToPdfFile(jasperPrint,pdfPath);
