模板工具Jaspersoft Studio创建模板并普通打印、分组打印；Jaspersoft Studio的基本使用方法
整合springboot打印，工程结构：
打印效果图
这里如果要分组打印，选中当前project右键选择Create Group，选择要根据哪个列分组，然后将fields下字段拖动后设置title，通过创建Variables可以自定义展现一些统计数据和页码展示的功能;Basic Elements里面有饼状图，图片等等各种也可以视情况插入到页面中
相关代码：
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; import org.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 /** * 基于javaBean方式填充数据 * GetMapping注解已经默认封装了@RequestMapping(method = RequestMethod.GET) */ @GetMapping("/testJasper") public void createPdf(HttpServletRequest request, HttpServletResponse response) throws IOException { //1.引入jasper文件 Resource resource = new ClassPathResource("template/testReport.jasper"); FileInputStream fis = new FileInputStream(resource.getFile()); //2.创建JasperPrint,向jasper文件中填充数据 ServletOutputStream os = response.getOutputStream(); try { /** * fis: jasper 文件输入流 * parameters ：向模板中输入的参数 * JasperDataSource：数据源（和数据库数据源不同） * 填充模板的数据来源（connection，javaBean，Map） * 填充空数据来源：JREmptyDataSource */ Map parameters = new HashMap<>(); parameters.put("printDate","2010-11-28"); //3.查询具体需要显示的数据集合 List<User> userList = getUserList(); //4.通过数据集合创建javaBean的数据源对象 JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(userList); //JasperPrint print = JasperFillManager.fillReport(fis, parameters,new JREmptyDataSource()); //有展示的表格数据就将new JREmptyDataSource()参数替换成javaBean的数据源对象 JasperPrint print = JasperFillManager.fillReport(fis, parameters,ds); //5.将JasperPrint以PDF的形式输出 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+"","张三"+i,"10010"+i); users.add(user); } return users; } }
springboot启动类
package com.test; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication(scanBasePackages = "com.test") public class JasperApplication { /** * 启动方法 */ 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配置文件
server: port: 8080 #spring配置 spring: #1.应用配置 application: name: jasper #指定服务名(和项目名称一样) #2.数据库连接池 datasource: driver-class-name: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/ihrm?useUnicode=true&characterEncoding=utf8 username: root password: root
解决中文乱码相关文件(这里只添加了华文宋体)
