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

 1     @RequestMapping("/report2")2     public void createtopdf(HttpServletRequest request, HttpServletResponse response) throws Exception {3         Resource resource = new ClassPathResource("templates/report2.jasper");4         FileInputStream fis = new FileInputStream(resource.getFile());5         ServletOutputStream os = response.getOutputStream();6         try {7             Map parameters = new HashMap<>();8             Connection conn = getConnection();9             JasperPrint print = JasperFillManager.fillReport(fis, parameters, conn);
10             JasperExportManager.exportReportToPdfStream(print, os);
11         } catch (JRException e) {
12             e.printStackTrace();
13         } finally {
14             os.flush();
15         }
16     }
17 　　　/**
18      * 返回一个mysql的数据连接对象
19      *
20      * @return
21      * @throws Exception
22      */
23     public Connection getConnection() {
24         String url = "jdbc:mysql://localhost:3306/xxxx?serverTimezone=UTC";
25         try {
26             Class.forName("com.mysql.cj.jdbc.Driver");
27             Connection conn = DriverManager.getConnection(url, "root", "root");
28             return conn;
29         } catch (ClassNotFoundException e) {
30             e.printStackTrace();
31         } catch (SQLException e) {
32             e.printStackTrace();
33         }
34         return null;
35     }

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(</span>"批量导出word文件成功"<span style="color: rgba(0, 0, 0, 1)">);} </span><span style="color: rgba(0, 0, 255, 1)">catch</span><span style="color: rgba(0, 0, 0, 1)"> (JRException e) {e.printStackTrace();} </span><span style="color: rgba(0, 0, 255, 1)">finally</span><span style="color: rgba(0, 0, 0, 1)"> {os.flush();}
}</span></pre>

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 </span>= <span style="color: rgba(0, 0, 255, 1)">new</span><span style="color: rgba(0, 0, 0, 1)"> FileInputStream(jfile);ServletOutputStream os </span>=<span style="color: rgba(0, 0, 0, 1)"> response.getOutputStream();</span><span style="color: rgba(0, 0, 255, 1)">try</span><span style="color: rgba(0, 0, 0, 1)"> {Map</span>&lt;String, Object&gt; parameters = <span style="color: rgba(0, 0, 255, 1)">new</span> HashMap&lt;&gt;<span style="color: rgba(0, 0, 0, 1)">();List</span>&lt;Map&lt;String, Object&gt;&gt; list =<span style="color: rgba(0, 0, 0, 1)"> getMapmodel11();System.out.println(list.toString());JRBeanCollectionDataSource ds </span>= <span style="color: rgba(0, 0, 255, 1)">new</span><span style="color: rgba(0, 0, 0, 1)"> JRBeanCollectionDataSource(list);JasperPrint print </span>=<span style="color: rgba(0, 0, 0, 1)"> JasperFillManager.fillReport(fis, parameters, ds);JasperExportManager.exportReportToPdfStream(print, os);} </span><span style="color: rgba(0, 0, 255, 1)">catch</span><span style="color: rgba(0, 0, 0, 1)"> (JRException e) {e.printStackTrace();} </span><span style="color: rgba(0, 0, 255, 1)">finally</span><span style="color: rgba(0, 0, 0, 1)"> {os.flush();}
}</span></pre>

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);response.setContentType("application/ms-word");response.setCharacterEncoding("UTF-8");String filename = "javabean";response.setHeader("Content-Disposition", "attachment; filename=" + URLEncoder.encode(filename, "UTF-8") + ".doc");JRDocxExporter exporter = new JRDocxExporter();exporter.setExporterInput(new SimpleExporterInput(print));exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(os));SimpleDocxExporterConfiguration configuration = new SimpleDocxExporterConfiguration();exporter.setConfiguration(configuration);exporter.exportReport();

    } </span><span style="color: rgba(0, 0, 255, 1)">catch</span><span style="color: rgba(0, 0, 0, 1)"> (JRException e) {e.printStackTrace();} </span><span style="color: rgba(0, 0, 255, 1)">finally</span><span style="color: rgba(0, 0, 0, 1)"> {os.flush();}
}</span></pre>

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）！！！
