easypoi插入超链接

今天遇到个问题，在excel中插入超链接，用于直接打开表格链接的文件

1. 类似这种，ctrl+鼠标左键能直接打开，下面用easypoi来实现

2. 查看easypoi文档，字段@Excel注解属性 isHyperlink = true 打开超链接插入功能

3. 实际代码实现

1. 实体类字段属性开启超链接

@Excel(name = "参数(input)", orderNum = "12", isHyperlink = true)
private String input;
@Excel(name = "返回值(returnInfo)", orderNum = "13", isHyperlink = true)
private String returnInfo;

2. 编写属性拦截器

/**
 * @author :yepk
 * @version :1.0
 * @apiNote :用于导出
 * @date :2019-04-24-9:25
 */

public class ExcelDataHandler extends ExcelDataHandlerDefaultImpl<ShakerRequestLogInfo> {
    @Override
    public Hyperlink getHyperlink(CreationHelper creationHelper, ShakerRequestLogInfo obj, String name, Object value) {
        Hyperlink hyperlink = creationHelper.createHyperlink(HyperlinkType.FILE);
        hyperlink.setLabel(name);
        hyperlink.setAddress((String) value);
        return hyperlink;
    }
}

3. 导出参数设置数据拦截器

ExportParams params = new ExportParams(String.format("%s-日志", date), last);
params.setDataHandler(new ExcelDataHandler());

4. 给对应实体类字段添加 超链接

// 本例子采用绝对路径
String inputPath = "txt/" + System.currentTimeMillis() + "-input.txt";
// 具体逻辑自行书写
info.setInput(inputPath);

5、完整版测试用例

/**
 * @author :yepk
 * @version :1.0
 * @apiNote :测试类
 * @date :2023-07-28-15:52
 */
@Data
public class TempBean implements Serializable {

    @Excel(name = "序号", orderNum = "0")
    private Integer id;

    @Excel(name = "标题", orderNum = "1")
    private String title;

    @Excel(name = "链接", orderNum = "2", isHyperlink = true)
    private String path;


    public static void main(String[] args) {
        List<TempBean> beanList = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            TempBean temp = new TempBean();
            temp.setId(i + 1);
            temp.setTitle("标题" + (i + 1));
            temp.setPath("https://www.baidu.com/s?wd=" + i);
            beanList.add(temp);
        }

        ExportParams params = new ExportParams("测试", "测试");
        params.setDataHandler(new ExcelDataHandler());
        Workbook workbook = ExcelExportUtil.exportExcel(params, TempBean.class, beanList);
        try {
            OutputStream os = new FileOutputStream("C:\\Users\\yepk\\Desktop\\test.xls");
            workbook.write(os);
            workbook.close();
            os.flush();
            os.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

class ExcelDataHandler extends ExcelDataHandlerDefaultImpl<TempBean> {
    @Override
    public Hyperlink getHyperlink(CreationHelper creationHelper, TempBean obj, String name, Object value) {
        Hyperlink hyperlink = creationHelper.createHyperlink(HyperlinkType.URL);
        hyperlink.setLabel(name);
        hyperlink.setAddress((String) value);
        return hyperlink;
    }
}
