1 前言

        之前用easypoi的导出用到了表头多层嵌套时，发现很麻烦，需要些很多的代码，所以今天看了一下easyexcel的导出，发现表头情况不复杂时和easypoi的难易程度是一样的，但是涉及到多层嵌套时，easyexcel就非常简单了。

相关依赖：

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>easyexcel</artifactId>
            <version>2.2.2</version>
        </dependency>

导出类：

@RestController
@RequestMapping("/test/")
public class TestEasyExcel {
 
    @GetMapping("/export")
    public void export( HttpServletResponse response) throws IOException {
 
        List<EasyExcelVo> list = new ArrayList<>();
 
        EasyExcelVo easyExcelVo = new EasyExcelVo();
        easyExcelVo.setName("文件夹");
        easyExcelVo.setResourceId("123");
        easyExcelVo.setResourceName("第一手资源");
        easyExcelVo.setAngle("正面");
        easyExcelVo.setBigArmLeft("fad");
        easyExcelVo.setBigArmRight("sgf");
        easyExcelVo.setSmallArmLeft("gsz");
        easyExcelVo.setSmallArmRight("gsz");
        easyExcelVo.setBodyRollDirection("向左转");
        easyExcelVo.setTurnHead("不转头");
        list.add(easyExcelVo);
 
        //解决中文乱码问题
        String fileName = new String("导出标记".getBytes(), "ISO-8859-1");
        response.setContentType("application/vnd.ms-excel");
        response.setHeader("Content-Disposition","attachment;filename="+fileName+".xlsx");
 
        writeExcel(response,list);
    }
 
 
        public static void writeExcel(HttpServletResponse response, List<EasyExcelVo> list) throws IOException {
            ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream()).build();
            //定义工具表对象
            WriteSheet sheet = EasyExcel.writerSheet(0, "导出标记").head(EasyExcelVo.class).build();
            //往excel文件中写入数据
            excelWriter.write(list, sheet);
            excelWriter.finish();
        }
 
 
 
 
 
 
}

EasyExcelVo：

@Data
public class EasyExcelVo {
 
    @ExcelIgnore
    private String id;
 
    @ExcelProperty(value = {"文件夹名称","文件夹名称","文件夹名称"},index = 0)
    @HeadStyle(fillBackgroundColor = 10) //设置表头颜色
    private String name;
 
    @ExcelProperty(value = {"资源id","资源id","资源id"},index = 1)
    private String resourceId;
 
    @ExcelProperty(value = {"资源名称","资源名称","资源名称"},index = 2)
    private String resourceName;
 
    @ExcelProperty(value = {"人工标注","拍摄角度","拍摄角度"},index = 3)
    private String angle;
 
    @ExcelProperty(value = {"人工标注","大臂抬起","左"},index = 4)
    private String bigArmLeft;
 
    @ExcelProperty(value = {"人工标注","大臂抬起","右"},index = 5)
    private String bigArmRight;
 
    @ExcelProperty(value = {"人工标注","小臂抬起","左"},index = 6)
    private String smallArmLeft;
 
    @ExcelProperty(value = {"人工标注","小臂抬起","右"},index = 7)
    private String smallArmRight;
 
    @ExcelProperty(value = {"人工标注","身体侧倾","身体侧倾"},index = 8)
    private String bodyRollDirection;
 
    @ExcelProperty(value = {"人工标注","身体侧倾","身体侧倾"},index = 9)
    private String turnHead;
 
 
}
