1、导入maven依赖

<dependency>
    <groupId>com.sargeraswang.util</groupId>
    <artifactId>excel-util</artifactId>
    <version>1.2.1</version>
</dependency>

官网1.2.4在maven中央仓库好像没有

2、准备实体类

public class Propmanger {

    private String proOrgCode;

    private String cityOrgCode;

    @ExcelCell(index = 0)
    private String provinceName;

    @ExcelCell(index = 1)
    private String cityName;

    //setter and getter 省略...
}

3、到出逻辑

        List<Propmanger> propmangers = propertyMangerService.seleceAll();
        System.out.println(propmangers.size());
        Map<String,String> map = new LinkedHashMap<>();
        map.put("provinceName","省");
        map.put("cityName","市");
        File f=new File("test.xls");
        OutputStream out =new FileOutputStream(f);

        ExcelUtil.exportExcel(map, propmangers, out);
        out.close();

4、结果
