1.首先新建一个SpringBoot微服务
2.只选择一个web就好
3.配置一下application.yml配置文件
server:
port: 8080
spring:
application:
name: easypoi
data:
thymeleaf:
encoding: UTF-8
servlet:
content-type: text/html
4.引入前台jar包以及easypoi核心jar包
org.springframework.boot
spring-boot-starter-thymeleaf
cn.afterturn
easypoi-base
3.0.3
cn.afterturn
easypoi-web
3.0.3
cn.afterturn
easypoi-annotation
3.0.3
5.接着我们创建model层实体类
package com.lsc.model;
import cn.afterturn.easypoi.excel.annotation.Excel;
import java.util.Date;
public class Person {
@Excel(name = "姓名", orderNum = "0")
private String name;
@Excel(name = "性别", replace = {"男_1", "女_2"}, orderNum = "1")
private String sex;
@Excel(name = "生日", exportFormat = "yyyy-MM-dd", orderNum = "2")
private Date birthday;
public Person(String name, String sex, Date birthday) {
this.name = name;
this.sex = sex;
this.birthday = birthday;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
}
6.创建easypoi导入导出工具类
package com.lsc.utils;
import cn.afterturn.easypoi.excel.ExcelExportUtil;
import cn.afterturn.easypoi.excel.ExcelImportUtil;
import cn.afterturn.easypoi.excel.entity.ExportParams;
import cn.afterturn.easypoi.excel.entity.ImportParams;
import cn.afterturn.easypoi.excel.entity.TemplateExportParams;
import cn.afterturn.easypoi.excel.entity.enmus.ExcelType;
import cn.afterturn.easypoi.excel.entity.params.ExcelExportEntity;
import com.lsc.model.Person;
import org.apache.commons.lang3.StringUtils;
import org.apache.poi.ss.usermodel.Workbook;
import org.springframework.web.multipart.MultipartFile;
import javax.servlet.http.HttpServletResponse;
import java.io.File;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import java.util.NoSuchElementException;
public class ExcelUtil {
public static void exportExcel(List list, String title, String sheetName, Class pojoClass, String fileName, boolean isCreateHeader, HttpServletResponse response) throws Exception {
ExportParams exportParams = new ExportParams(title, sheetName);
exportParams.setCreateHeadRows(isCreateHeader);
defaultExport(list, pojoClass, fileName, response, exportParams);
}
public static void exportExcel(List list, String title, String sheetName, Class pojoClass,String fileName, HttpServletResponse response) throws Exception {
defaultExport(list, pojoClass, fileName, response, new ExportParams(title, sheetName));
}
public static void exportExcel(List list, ExportParams exportParams, Class pojoClass,String fileName, HttpServletResponse response) throws Exception {
defaultExport(list, pojoClass, fileName, response, exportParams);
}
public static void exportExcel(List
7.创建controller层测试方法
package com.lsc.controller;
import com.lsc.model.Person;
import com.lsc.utils.ExcelUtil;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletResponse;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
@RequestMapping("test")
@RestController
public class TestController {
@RequestMapping("export")
public void export(HttpServletResponse response) throws Exception {
//模拟从数据库获取需要导出的数据
List personList = new ArrayList<>();
Person person1 = new Person("路飞","1",new Date());
Person person2 = new Person("娜美","2", new Date());
Person person3 = new Person("索隆","1", new Date());
Person person4 = new Person("小狸猫","1", new Date());
personList.add(person1);
personList.add(person2);
personList.add(person3);
personList.add(person4);
//导出操作
ExcelUtil.exportExcel(personList,"花名册","草帽一伙",Person.class,"海贼王.xls",response);
}
@RequestMapping("importExcel")
public void importExcel() throws Exception {
String filePath = "E:\\海贼王.xls";
//解析excel,
List personList = ExcelUtil.importExcel(filePath,1,1,Person.class);
//也可以使用MultipartFile,使用 FileUtil.importExcel(MultipartFile file, Integer titleRows, Integer headerRows, Class pojoClass)导入
System.out.println("导入数据一共【"+personList.size()+"】行");
//TODO 保存数据库
}
}
8.创建页面跳转路径PageController
package com.lsc.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("page")
public class PageController {
@RequestMapping("toindex")
public String toindex(){
return "list";
}
}
9.创建前台页面,一个导出的按钮。指定Controller层测试方法的导出方法跳转路径
Title
10.目前的包结构如下:
11.接着我们访问前台路径http://localhost:8080/page/toindex
12.点击导出按钮,就会导出出来了。
13.这是excel中的内容:
完成。只是一个小demo。经供参考。谢谢
