jasperReport和Ireport

用JasperResport生成模板文件,放在WEB-INF目录下

maven引入依赖

        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-all</artifactId>

根据jasperReport模板生成PDF的模板代码

// 根据 jasperReport模板 生成pdf
        // 读取模板文件
        String jrxml = ServletActionContext.getServletContext().getRealPath(
                "/WEB-INF/jasper/xxx.jrxml");
        JasperReport report = JasperCompileManager.compileReport(jrxml);

        // 设置模板数据
        // Parameter变量
        Map<String, Object> paramerters = new HashMap<String, Object>();
        paramerters.put("company", "xxx");
        // Field变量
        JasperPrint jasperPrint = JasperFillManager.fillReport(report,
                paramerters, new JRBeanCollectionDataSource(你的数据));
        
        // 生成PDF客户端
        JRPdfExporter exporter = new JRPdfExporter();
        exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
        exporter.setParameter(JRExporterParameter.OUTPUT_STREAM,
                ServletActionContext.getResponse().getOutputStream());
        exporter.exportReport();// 导出
        ServletActionContext.getResponse().getOutputStream().close();
