2. 如何在springboot 项目中实现各种报表导出、PDF文件导出

2.1使用IDEA创建maven工程 

打开idea,New Project选择Maven Archetype ,创建web工程

右键新建Module 

 

    工程是这样的:   

 设置一下工程:

 pom.xml变灰了,需要设置一下,把这个勾选去掉,点击“应用”

 添加 springboot、ureport、数据库相关的依赖 pom.xml

</project>

 2.2添加yml配置信息

application.yml:

server:
  port: 8090
  servlet:
    context-path:
spring:
  http:
    encoding:
      force: true
      enabled: true
      charset: UTF-8
  datasource:
    driver-class-name: ***.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false&allowMultiQueries=true&nullNamePatternMatchesAll=true
    username: root
    password: 123456
    type: ***.alibaba.druid.pool.DruidDataSource

  resources:
    static-locations: classpath:/,classpath:/static/

2.3添加引用UReport2的Spring配置文件context.xml 

放在resources

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!-- 创建context.xml是第六步,引入ureport2报表xml配置文件 -->
    <import resource="classpath:ureport-console-context.xml" />
    <bean id="propertyConfigurer" parent="ureport.props">
        <property name="location">
            <value>classpath:config.properties</value>
        </property>
    </bean>
</beans>

2.4添加property文件

config.properties

#配置文件系统对应的报表文件地址
ureport.fileStoreDir=D:/work/ForTest/SpringBootDemo/ureport/src/main/webapp/WEB-INF/ureportfiles
# 是否禁用
ureport.disableFileProvider=false
ureport.debug=true
ureport.disableHttpSessionReportCache=false
# 配置ureport根路径
ureport.contextPath=/ureport

2.5新建webapp目录,新建WEB-INF

在WEB-INF下新建ureportfiles目录存放报表模板文件

2.7 创建启动类 

Application.java
package org.springboot.demo;

import ***.bstek.ureport.console.UReportServlet;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@ImportResource("classpath:context.xml")
public class Application {
    public static void main(String[] args) {

       try {
           SpringApplication.run(Application.class, args);
       }catch (Exception e){
           System.out.println(e.getMessage());
       }
    }
    // ureport2使用到servlet
    @Bean
    public ServletRegistrationBean buildUReportServlet(){
        return new ServletRegistrationBean(new UReportServlet(),"/ureport/*");
    }
}

 执行启动 点击Application.java 右键启动项目

 浏览器输入:http://localhost:8090/ureport/designer

就可以访问到ureport 模板设计页面了

 2.8 新建 ureport 数据源类

新建 ureportSource.java
package org.springboot.demo.util;
import org.springframework.stereotype.***ponent;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

@***ponent("ureportSource")
public class ureportSource {
    /**
     *
     * @param dsName
     * @param datasetName
     * @param parameters
     * @return
     */
    public List<Map<String, Object>> usrInfo(String dsName, String datasetName, Map<String, Object> parameters) {
        List<Map<String, Object>> mapList = new ArrayList<>();
        mapList.add(parameters);
        return mapList;
    }
}

新建实体类

user.java

package org.springboot.demo.entity;

import lombok.Data;
import java.io.Serializable;
@Data
public class user implements Serializable{
    private static final long serialVersionUID = -1518203115685933730L;
    private String userName;
    private String birthDate;
    private String sex;
    private String school;
    private String grade;
    private Integer age;
    private String address;
}

再次 重启项目

记得一定要重启,或者热部署

 2.9 配置ureport数据源

ureport数据源 有三种:直连数据源、SpringBean连接、内置数据源

这个优先使用SpringBean连接,安全性高,使用简单

这里配置SpringBean连接、点击中间这个按钮

2.9.1新建数据源

Bean ID是我们建的那个java类的类名,这个需要对应上

 2.9.2 添加数据集

 

确定后,点击userInfo 刷新,就可以看到实体类的属性了

2.9.3设计模板

分别给每个表格赋值 

属性名称,使用“普通文本” 类型

属性值,使用“数据集” 类型

所有属性和值设置好后,点击保存

保存后,我们可以看到工程下生成了一个报表模板文件

3.0 新建导出excel、pdf公共类

ExportUtils.java

package org.springboot.demo.util;

import ***.bstek.ureport.export.ExportConfigureImpl;
import ***.bstek.ureport.export.ExportManager;

import java.io.FileOutputStream;
import java.io.OutputStream;
import java.util.Map;
import java.util.Objects;
/**
导出excel、pdf
 */
public class ExportUtils {
    public static void exportPdf(ExportManager exportManager, String sourcePath, String targetPath, Map<String, Object> param) throws Exception {
        try {
            OutputStream fos = new FileOutputStream(targetPath);
            try {
                ExportConfigureImpl exportConfigure = new ExportConfigureImpl(sourcePath, param, fos);
                exportManager.exportPdf(exportConfigure);
            } catch (Exception e) {
                throw new Exception("exportPdf error", e);
            } finally {
                if (fos != null) {
                    try {
                        fos.close();
                    }catch(Exception e) {
                        throw new Exception("exportPdf error", e);
                    }
                }
            }
        } catch (Exception e) {
            throw new Exception("exportPdf error", e);
        }
    }
    public static void exportExcel(ExportManager exportManager, String sourcePath, String targetPath, Map<String, Object> param) throws Exception {
        try {
            OutputStream fos = new FileOutputStream(targetPath);
            try {
                String ext = targetPath.substring(targetPath.indexOf(".") + 1);
                ExportConfigureImpl exportConfigure = new ExportConfigureImpl(sourcePath, param, fos);
                if (Objects.equals(ext, "xls")) {
                    exportManager.exportExcel97(exportConfigure);
                } else {
                    if (!Objects.equals(ext, "xlsx")) {
                        throw new Exception("File name is not support!");
                    }
                    exportManager.exportExcel(exportConfigure);
                }
            } catch (Exception e) {
                throw new Exception("exportExcel error", e);
            } finally {
                if (fos != null) {
                    try {
                        fos.close();
                    } catch (Exception e) {
                        throw new Exception("exportExcel error", e);
                    }
                }
            }
        } catch (Exception e) {
            throw new Exception("exportExcel error", e);
        }
    }

}

3.1 新建测试类

urePortController.java
package org.springboot.demo.controller;


import ***.bstek.ureport.export.ExportManager;

import lombok.SneakyThrows;

import org.springboot.demo.util.ExportUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;

@RestController
@RequestMapping("/user")
public class urePortController {
    @Autowired
    private ExportManager exportManager;

    @SneakyThrows
    @RequestMapping("/generatePDF")
    public Map<String, Object> generatePDF(){
        Map<String,Object> dataMap = new HashMap<>();
        dataMap.put("userName","张三");
        dataMap.put("age","20");
        dataMap.put("sex","男");
        dataMap.put("grade","大三");
        dataMap.put("birthDate","2003-01-01");
        dataMap.put("address","广州市天河区");
        dataMap.put("school","广东工业大学");
        String filePath="D:/userInfo.pdf";
        ExportUtils.exportPdf(exportManager,"file:userInfo.ureport.xml",filePath,dataMap);
        //返回页面信息
        Map<String,Object> result = new HashMap<>();
        result.put("result","Su***ess");
        result.put("data",dataMap);
        return result;
    }
    @SneakyThrows
    @RequestMapping("/generateExcel")
    public Map<String, Object> generateExcel(){
        Map<String,Object> dataMap = new HashMap<>();
        dataMap.put("userName","张三");
        dataMap.put("age","20");
        dataMap.put("sex","男");
        dataMap.put("grade","大三");
        dataMap.put("birthDate","2003-01-01");
        dataMap.put("address","广州市天河区");
        dataMap.put("school","广东工业大学");
        String filePath="D:/userInfo.xls";
        ExportUtils.exportExcel(exportManager,"file:userInfo.ureport.xml",filePath,dataMap);
        //返回页面信息
        Map<String,Object> result = new HashMap<>();
        result.put("result","Su***ess");
        result.put("data",dataMap);
        return result;
    }
