之前写过一篇极其简单的excel导入导出,是单个文件的:
Springboot 最简单的结合MYSQL数据实现EXCEL表格导出及数据导入_小目标青年的博客-CSDN博客
还写过一篇单个,多个 excel文件导出,转成ZIP包的:
Springboot 导出Excel文件,多个需要压缩成 zip 包_小目标青年的博客-CSDN博客
然后:
于是该篇就来了, 指定模板(自定义)导出数据,就像:
开始实战:
pom.xml依赖:
<!-- 导入和导出-->
<dependency>
<groupId>cn.afterturn</groupId>
<artifactId>easypoi-base</artifactId>
<version>3.0.3</version>
</dependency>
<dependency>
<groupId>cn.afterturn</groupId>
<artifactId>easypoi-web</artifactId>
<version>3.0.3</version>
</dependency>
<dependency>
<groupId>cn.afterturn</groupId>
<artifactId>easypoi-annotation</artifactId>
<version>3.0.3</version>
</dependency>
我们导出数据的实体类 UserExcelDTO.java
import cn.afterturn.easypoi.excel.annotation.Excel;
/**
* @Author: JCccc
* @Date: 2022-7-14 10:58
* @Description:
*/
public class UserExcelDTO {
@Excel(name = "学号", height = 8, width = 13, isImportField = "true")
private Integer id;
@Excel(name = "姓名", height = 8, width = 13, isImportField = "true")
private String userName;
@Excel(name = "年龄", height = 8, width = 13, isImportField = "true")
private String userAge;
@Override
public String toString() {
return "User{" +
"id=" + id +
", userName='" + userName + '\'' +
", userAge='" + userAge + '\'' +
'}';
}
public UserExcelDTO() {
}
public UserExcelDTO(Integer id, String userName, String userAge) {
this.id = id;
this.userName = userName;
this.userAge = userAge;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserAge() {
return userAge;
}
public void setUserAge(String userAge) {
this.userAge = userAge;
}
}
里面使用了 @Excel注解标记一下相关字段
然后自定义模板, 注意里面细节:
每一行数据都是一个对象,都在list 里面,
所以看到 首个字段 和 末尾最后的字段 是有 括号的 {}:
示例格式:
{{$fe: list t.id
t.userName
t.userAge}}
然后把自定义模板文件丢到 静态资源路径下:
然后是实现使用自定义模板,填充list数据导出excel文件:
/**
* excel导出 列表 指定模板
*
* @return
*/
@GetMapping(value = "/exportAssignTemplateExcel")
public void opportunityExport(HttpServletResponse response) {
List<UserExcelDTO> exportList = new ArrayList<>();
UserExcelDTO userExcel1=new UserExcelDTO(1001,"JCccc","18");
UserExcelDTO userExcel2=new UserExcelDTO(1002,"ACccc","29");
UserExcelDTO userExcel3=new UserExcelDTO(1003,"GCccc","50");
exportList.add(userExcel1);
exportList.add(userExcel2);
exportList.add(userExcel3);
Map map = Maps.newHashMap();
map.put("list", exportList);
//获取导出模板地址
ClassPathResource classPathResource = new ClassPathResource("static/export/template/MyUserTemplate.xlsx");
String path = classPathResource.getPath();
TemplateExportParams templateExportParams1 = new TemplateExportParams(path);
Workbook wb = ExcelExportUtil.exportExcel(templateExportParams1, map);
String time = LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy_MM_dd_HH_mm_ss"));
String fileName = "用户数据"+time+".xlsx";
try {
response.setContentType("application/octet-stream;charset=utf-8");
response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "utf-8"));
response.flushBuffer();
wb.write(response.getOutputStream());
} catch (IOException e) {
e.printStackTrace();
}
}
代码简析:
调用一下接口,看看效果:
excel文件内容:
好了,该篇就到这。
