由于最近系统中要做报表,所以使用到了Ireport来制作报表.我就不再介绍Ireport是干嘛的了.下面我将用SpringBoot整合Ireport的一个入门Demo来告诉你们在项目中怎么使用iReport导出pdf文件.

 

• 创建一个maven项目

• Pom.xml配置

---

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

• 编写一个简单的hello.jrxml

• 导入到项目中去

• 编写Controller

---

@RestController

public class HelloController {

 

/**

 * 导入为PDF

 * @return

 * @throws Exception

 */

@RequestMapping(value="/exportPdf")

public ResponseEntity<byte[]> exportPdf() throws Exception{

 

   PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();

   Resource resource = resolver.getResource("jasper/HelloReport.jasper");

  JasperPrint jasperPrint=JasperFillManager.fillReport(resource.getInputStream(), null,new JREmptyDataSource());

  byte[] body = JasperExportManager.exportReportToPdf(jasperPrint);

  HttpHeaders header=new HttpHeaders();

  header.setContentType(MediaType.APPLICATION_PDF);

  header.add("Content-Disposition", "inline;filename=hello.pdf");

  return new ResponseEntity<byte[]>(body, header, HttpStatus.OK);

 

  }

}

---

• 启动SpringBoot项目

  

---

@SpringBootApplication(scanBasePackages="com.hjy")

public class App {

public static void main(String[] args) throws Exception {

      SpringApplication.run(App.class, args);

  }

}

---

• 项目目录结构

• 访问PDF
