Easypoi 是一个基于 Apache POI 和 Jxls 封装的 Java Excel 工具类库,提供了丰富的导入导出功能。以下是 Easypoi 的导入导出功能的使用方法:
1. 导出 Excel
(1)创建实体类,实体类中的属性需要添加 @Excel 注解,如下所示:
```
public class User {
@Excel(name = "ID", orderNum = "0")
private Integer id;
@Excel(name = "姓名", orderNum = "1")
private String name;
@Excel(name = "年龄", orderNum = "2")
private Integer age;
}
```
(2)调用 ExcelExportUtil.exportExcel 方法导出 Excel,示例代码如下:
```
List<User> userList = userService.getUserList();
Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams("用户列表", "用户"), User.class, userList);
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode("用户列表.xls", "UTF-8"));
workbook.write(response.getOutputStream());
```
2. 导入 Excel
(1)创建实体类,实体类中的属性需要添加 @Excel 注解,如下所示:
```
public class User {
@Excel(name = "ID", orderNum = "0")
private Integer id;
@Excel(name = "姓名", orderNum = "1")
private String name;
@Excel(name = "年龄", orderNum = "2")
private Integer age;
}
```
(2)调用 ExcelImportUtil.importExcel 方法导入 Excel,示例代码如下:

userService.saveUserList(userList);
