使用 Jaspersoft Studio 设计报表样式

用你熟悉的环境设计一套最简单的模板,名称定义为: Reports.jrxml
report_template.png
下载源文件:report.jrxml

  • 语法比较特殊,需要努力学习

    新建 Spring Boot 项目

  • 新建 Spring Boot 项目,不多说
    需包含的内容比较特殊,pom.xml,jasperreports 是依赖包,jasperreports-fonts 是字体支持包

          <dependency>
              <groupId>net.sf.jasperreports</groupId>
              <artifactId>jasperreports</artifactId>
              <version>6.15.0</version>
          </dependency>
          <dependency>
              <groupId>net.sf.jasperreports</groupId>
              <artifactId>jasperreports-fonts</artifactId>
              <version>6.15.0</version>
          </dependency>
          <dependency>
              <groupId>org.springframework</groupId>
              <artifactId>spring-support</artifactId>
              <version>2.0.8</version>
          </dependency>
  • 新建各种类
    controller, domain, repository, service, 其他,大概目录结构如下
    report2.png
  • 创建 Postgresql 数据表

    CREATE TABLE public.product
    (
      id bigint NOT NULL,
      name character varying(255) COLLATE pg_catalog."default",
      price numeric,
      quantity integer,
      category_name character varying(255) COLLATE pg_catalog."default",
      CONSTRAINT product_pkey PRIMARY KEY (id)
    )

集成 JasperReports 到 Spring Boot 项目

中文支持文章:Spring Boot 集成 JasperReports,并支持中文PDF

  • Service 服务层处理要求

    @RequestMapping(value = "/report", method = RequestMethod.GET)
      public void report(HttpServletResponse response, @RequestParam(name = "type", defaultValue = "pdf") String type) throws Exception {
    
          JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(productService.report());
          InputStream inputStream = this.getClass().getResourceAsStream("/report_templates/report.jrxml");
          JasperReport jasperReport = JasperCompileManager.compileReport(inputStream);
          JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, dataSource);
    
          switch (type) {
          case "html":
              response.setContentType("text/html;charset=utf-8");
              HtmlExporter exporter = new HtmlExporter(DefaultJasperReportsContext.getInstance());
              exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
              exporter.setExporterOutput(new SimpleHtmlExporterOutput(response.getWriter()));
              exporter.exportReport();
              break;
    
          case "pdf":
    
          default:
              JRPdfExporter exporterPdf = new JRPdfExporter();
              exporterPdf.setExporterInput(new SimpleExporterInput(jasperPrint));
              OutputStream outputStream = response.getOutputStream();
              exporterPdf.setExporterOutput(new SimpleOutputStreamExporterOutput(outputStream));
              exporterPdf.exportReport();
              break;
          }
    
      }
