jasperreport（jasperreport背景透明）

1.代码如下

传递parameters参数，单个属性



/**
 * 打印员工pdf报表
 */
@RequestMapping(value = "/{id}/pdf" , method = RequestMethod.GET)
public void pdf(@PathVariable String id) throws IOException {
    //1.引入jasper文件
    org.springframework.core.io.Resource resource = new ClassPathResource("templates/profile.jasper");
    FileInputStream fis = new FileInputStream(resource.getFile());

    //2.构造数据
    //用户详情数据
    UserCompanyPersonal personal = userCompanyPersonalService.findById(id);
    //用户岗位信息数据
    UserCompanyJobs jobs = userCompanyJobsService.findById(id);

    //用户头像
    String staffPhoto = "http://qav8b72pi.bkt.clouddn.com/" + id + "?t=100";

    //3.填充pdf模版数据,并输出pdf
    Map params = new HashMap();


    Map<String, Object> personalMap = BeanMapUtils.beanToMap(personal);
    Map<String, Object> jobsMap = BeanMapUtils.beanToMap(jobs);

    params.putAll(personalMap);
    params.putAll(jobsMap);
    params.put("staffPhoto" , staffPhoto);

    ServletOutputStream sos = response.getOutputStream();
    try{
        JasperPrint print = JasperFillManager.fillReport(fis , params , new JREmptyDataSource());
        JasperExportManager.exportReportToPdfStream(print , sos);
    }catch (JRException e){
        e.printStackTrace();
    }finally {
        sos.flush();
    }

}

传递数据库jabc数据源列表参数

右键添加band

java bean数据源

创建field

构造模板

package cn.itcast.controller;

import cn.itcast.domain.User;

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.sql.Connection;
import java.sql.DriverManager;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

@RestController
public class JasperController04 {

    /**
     *  基于javaBean数据源的形式填充数据
     */
    @GetMapping("/testJasper4")
    public void createPdf(HttpServletRequest request, HttpServletResponse response) throws Exception {
        //1.引入jasper文件
        Resource resource = new ClassPathResource("templates/testBean.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 {
            Map parameters = new HashMap<>();
            //构建javaBean的数据源
            //1.获取到对象的list集合
            List<User> userList = getUserList();
            //2.通过list集合创建javaBean的数据源对象
            JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(userList);
            JasperPrint print = JasperFillManager.fillReport(fis,parameters,ds);
            JasperExportManager.exportReportToPdfStream(print,os);
        } catch (JRException e) {
            e.printStackTrace();
        }finally {
            os.flush();
        }
    }

    public List<User> getUserList() {
        List<User> list = new ArrayList<>();
        for(int i=0;i<10;i++) {
            User user = new User(i+"", "用户"+i, "传智播客","讲师", "1380000000"+i);
            list.add(user);
        }
        return list;
    }


}

2.模板如下

fonts.xml


    <?xml version="1.0" encoding="UTF-8"?>

3.模板设计如下
