package com.test.controller; import com.test.entity.User; import net.sf.jasperreports.engine.*; import net.sf.jasperreports.engine.data.JRBeanCollectionDataSource; import org.springframework.core.io.ClassPathResource; import org.springframework.core.io.Resource; importorg.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; import javax.servlet.ServletOutputStream; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.FileInputStream; import java.io.IOException;import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; @RestController public class JasperController { //模板工具：Jaspersoft Studio /** * 基於javaBean方式填充資料 * GetMapping註解已經預設封裝了@RequestMapping(method = RequestMethod.GET) */ @GetMapping("/testJasper")public void createPdf(HttpServletRequest request, HttpServletResponse response) throws IOException { //1.引入jasper檔案 Resource resource = new ClassPathResource("template/testReport.jasper"); FileInputStream fis = new FileInputStream(resource.getFile()); //2.建立JasperPrint,向jasper檔案中填充資料 ServletOutputStream os = response.getOutputStream(); try { /** * fis: jasper 檔案輸入流 * parameters ：向模板中輸入的引數 * JasperDataSource：資料來源（和資料庫資料來源不同） * 填充模板的資料來源（connection，javaBean，Map） * 填充空資料來源：JREmptyDataSource */ Map parameters = new HashMap<>(); parameters.put("printDate","2010-11-28"); //3.查詢具體需要顯示的資料集合 List<User> userList = getUserList(); //4.通過資料集合建立javaBean的資料來源物件 JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(userList); //JasperPrint print = JasperFillManager.fillReport(fis, parameters,new JREmptyDataSource()); //有展示的表格資料就將new JREmptyDataSource()引數替換成javaBean的資料來源物件 JasperPrint print = JasperFillManager.fillReport(fis, parameters,ds); //5.將JasperPrint以PDF的形式輸出 JasperExportManager.exportReportToPdfStream(print,os); } catch (JRException e) { e.printStackTrace(); }finally { os.flush(); } } public List<User> getUserList() { ArrayList<User> users = new ArrayList<>(); for(int i=0;i<3;i++){ User user = new User(i+"","張三"+i,"10010"+i); users.add(user); } return users; } }
springboot啟動類
package com.test; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication(scanBasePackages = "com.test") public class JasperApplication { /** * 啟動方法 */ public static void main(String[] args) { SpringApplication.run(JasperApplication.class,args); } }
javaBean
package com.test.entity; public class User { private String orderId; private String userName; private String phone; public User(String orderId, String userName, String phone) { this.orderId = orderId; this.userName = userName; this.phone = phone; } public String getOrderId() { return orderId; } public void setOrderId(String orderId) { this.orderId = orderId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getPhone() { return phone; } public void setPhone(String phone) { this.phone = phone; } }
springboot配置檔案
server: port: 8080 #spring配置 spring: #1.應用配置 application: name: jasper #指定服務名(和專案名稱一樣) #2.資料庫連線池 datasource: driver-class-name: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/ihrm?useUnicode=true&characterEncoding=utf8 username: root password: root
