JasperReport和iReport的java集成大全

好久没更新了，最近在研究java开源报表

JasperReports和 iReport

实际使用效果还不错，美中不足的是没有自带补空行的功能（通过给报表数据增加null值可以实现）和文字旋转（好像不支持带@的旋转字体）

不过应付日常简单报表已经绰绰有余，还是值得记录一下！！！

 

通过 iReport设计报表请自己学习，比较容易上手，我只贴出调用报表预览打印的相关代码

先上 pom.xml

使用jdbc数据源示例

不带参数

    @RequestMapping("/report2")
    public void createtopdf(HttpServletRequest request, HttpServletResponse response) throws Exception {
        Resource resource = new ClassPathResource("templates/report2.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map parameters = new HashMap<>();
            Connection conn = getConnection();
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, conn);
            JasperExportManager.exportReportToPdfStream(print, os);
        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }
　　　/**
     * 返回一个mysql的数据连接对象
     *
     * @return
     * @throws Exception
     */
    public Connection getConnection() {
        String url = "jdbc:mysql://localhost:3306/xxxx?serverTimezone=UTC";
        try {
            Class.forName("com.mysql.cj.jdbc.Driver");
            Connection conn = DriverManager.getConnection(url, "root", "root");
            return conn;
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return null;
    }

带有参数可以进行数据筛选的

设计报表时设置相应的参数如下

核心代码如下：

    /**
     * 可以带有参数筛选的JDBC连接源填充
     *
     * @param request
     * @param response
     * @param params
     * @throws Exception
     */
    @RequestMapping("/params")
    public void createpdf33(HttpServletRequest request, HttpServletResponse response, String params) throws Exception {
        Resource resource = new ClassPathResource("templates/hasparams.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            parameters.put("id", params);
            Connection conn = getConnection();
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, conn);
            JasperExportManager.exportReportToPdfStream(print, os);
        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

使用javabean作为数据源填充数据调用示例：

    /**
     * 使用javabean填充数据
     *
     * @param request
     * @param response
     * @throws Exception
     */
    @RequestMapping("/bean2")
    public void javabeantest222(HttpServletRequest request, HttpServletResponse response) throws Exception {
        Resource resource = new ClassPathResource("templates/bean2.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            List<SysUser> list = getuser();
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);

//            Connection conn = getConnection();
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, ds);
            JasperExportManager.exportReportToPdfStream(print, os);
        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

使用LIst<Map<String,Object>>填充数据调用方式：

    /**
     * 使用List<Map<String，Object>>集合填充数据
     *
     * @param request
     * @param response
     * @throws Exception
     */
    @RequestMapping("/testmap")
    public void testmapcollection(HttpServletRequest request, HttpServletResponse response) throws Exception {
        Resource resource = new ClassPathResource("templates/javabean.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            List<Map<String, Object>> list = getMapmodel();
            System.out.println(list.toString());
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
//            Connection conn = getConnection();
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, ds);
            String filename = "javabean";
            response.setContentType("application/pdf");
//            response.setHeader("Content-Disposition", "attachment; filename=" + URLEncoder.encode(filename, "UTF-8") + ".pdf");
            JasperExportManager.exportReportToPdfStream(print, os);
        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

使用HTML方式预览报表调用代码：

    /**
     * 预览html格式
     *
     * @param request
     * @param response
     * @throws Exception
     */
    @RequestMapping("/html")
    public void testhtml(HttpServletRequest request, HttpServletResponse response) throws Exception {
        Resource resource = new ClassPathResource("templates/javabean.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            List<Map<String, Object>> list = getMapmodel();
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
//            Connection conn = getConnection();
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, ds);
//            JasperExportManager.exportReportToPdfStream(print,os);
            JasperExportManager.exportReportToHtmlFile(print, request.getServletContext().getRealPath("/") + "test.html");
            response.sendRedirect("test.html");
        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

在服务器端批量转成word代码示例：

    /**
     * 在服务器端批量导出生成word文件，可以一次性导出多个JasperPrint
     * @param request
     * @param response
     * @throws Exception
     */
    @RequestMapping("/report.doc")
    public void testword(HttpServletRequest request, HttpServletResponse response) throws Exception {
        Resource resource = new ClassPathResource("templates/javabean.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            List<Map<String, Object>> list = getMapmodel();
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
//            Connection conn = getConnection();
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, ds);
//            JasperExportManager.exportReportToPdfStream(print,os);
//            JasperExportManager.exportReportToHtmlFile(print, request.getServletContext().getRealPath("/") + "test.html");
//            response.sendRedirect("test.html");
            JRDocxExporter exporter = new JRDocxExporter();
            List<JasperPrint> plist = new ArrayList<>();
            plist.add(print);
            exporter.setExporterInput(SimpleExporterInput.getInstance(plist));
            exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(new File("D:/javabean.doc")));
            exporter.exportReport();

            System.out.println("批量导出word文件成功");

        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

直接使用 .jrxml模板先进行代码编译然后调用示例：

    /**
     * 把jrxml文件编译成 jrasper文件，之后填充数据
     * @param request
     * @param response
     * @throws IOException
     * @throws SQLException
     */
    @RequestMapping("/compile")
    public void Compilejrxml(HttpServletRequest request,HttpServletResponse response)throws IOException,SQLException {
        String path = "D:\\Idea Projects\\jasper\\src\\main\\resources\\templates\\report6.jrxml";
        File  file = new File(path);
        String parentPath = file.getParent();
        String jrxmlDestSourcePath = parentPath+"/report9.jasper";
        try {
            JasperCompileManager.compileReportToFile(path,
                    jrxmlDestSourcePath);
        } catch (JRException e) {
            e.printStackTrace();
        }
        File jfile = new File(parentPath+"\\report9.jasper");

        FileInputStream fis = new FileInputStream(jfile);
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            List<Map<String, Object>> list = getMapmodel11();
            System.out.println(list.toString());
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, ds);
            JasperExportManager.exportReportToPdfStream(print, os);
        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

报表生成pdf并在客户端下载示例：

    /**
     * 下载报表pdf格式
     * @param request
     * @param response
     * @throws Exception
     */
    @RequestMapping("/downloadpdf")
    public void testmapcollection1234(HttpServletRequest request, HttpServletResponse response) throws Exception {
        Resource resource = new ClassPathResource("templates/javabean.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            List<Map<String, Object>> list = getMapmodel();
            System.out.println(list.toString());
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, ds);
            response.setContentType("application/pdf");
            response.setCharacterEncoding("UTF-8");
            String filename = "javabean";
            response.setHeader("Content-Disposition", "attachment; filename=" + URLEncoder.encode(filename, "UTF-8") + ".pdf");
            JRPdfExporter exporter = new JRPdfExporter();
            exporter.setExporterInput(new SimpleExporterInput(print));
            exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(os));
            SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
            exporter.setConfiguration(configuration);
            exporter.exportReport();
        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

报表生成Excel并下载至客户端代码：

    /**
     * 报表下载xls格式
     * @param request
     * @param response
     * @throws Exception
     */
    @RequestMapping("/downloadxls")
    public void testmapcollection12342(HttpServletRequest request, HttpServletResponse response) throws Exception {
        Resource resource = new ClassPathResource("templates/javabean.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            List<Map<String, Object>> list = getMapmodel();
            System.out.println(list.toString());
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, ds);
            response.setContentType("application/xls");
            response.setCharacterEncoding("UTF-8");
            String filename = "javabean";
            response.setHeader("Content-Disposition", "attachment; filename=" + URLEncoder.encode(filename, "UTF-8") + ".xls");
            JRXlsExporter exporter = new JRXlsExporter();
            exporter.setExporterInput(new SimpleExporterInput(print));
            exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(os));
            SimpleXlsExporterConfiguration configuration = new SimpleXlsExporterConfiguration();
            exporter.setConfiguration(configuration);
            exporter.exportReport();
        } catch (JRException e) {
            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

 

报表生成word格式并下载至客户端代码示例：

    /**
     * 报表下载word（DOC）格式
     * @param request
     * @param response
     * @throws Exception
     */
    @RequestMapping("/downloadword")
    public void testmapcollection1232342(HttpServletRequest request, HttpServletResponse response) throws Exception {
        Resource resource = new ClassPathResource("templates/javabean.jasper");
        FileInputStream fis = new FileInputStream(resource.getFile());
        ServletOutputStream os = response.getOutputStream();
        try {
            Map<String, Object> parameters = new HashMap<>();
            List<Map<String, Object>> list = getMapmodel();
            System.out.println(list.toString());
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
            JasperPrint print = JasperFillManager.fillReport(fis, parameters, ds);

            e.printStackTrace();
        } finally {
            os.flush();
        }
    }

JasperReports生成的PDF报表会存在中文显示的问题，需要自行设置字体

处理如下

在项目的 resources文件夹下新建文件：

fonts.xml

jasperreports_extension.properties

然后下载ttf的字体文件，放在同级目录下，我下载的时 STSong.ttf 即为宋体

fonts.xml如下

<?xml version="1.0" encoding="UTF-8"?>
<fontFamilies>
    <fontFamily name="仿宋">
        <normal>STSONG.TTF</normal>
        <bold>STSONG.TTF</bold>
        <italic>STSONG.TTF</italic>
        <boldItalic>STSONG.TTF</boldItalic>
        <pdfEncoding>Identity-H</pdfEncoding>
        <pdfEmbedded>true</pdfEmbedded>
        <exportFonts>
            <export key="net.sf.jasperreports.html">'仿宋', Arial, Helvetica, sans-serif</export>
            <export key="net.sf.jasperreports.xhtml">'仿宋', Arial, Helvetica, sans-serif</export>
        </exportFonts>
    </fontFamily>

</fontFamilies>

jasperreports_extension.properties的内容如下

net.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.lobstertwo=fonts.xml

项目的层级如下：

至此，日常简单报表应该已经能彻底满足需求了，代码也比较详细，谢谢大家，有问题可以留言（反正我也不会给你答疑哈哈哈哈）！！！
