2 工具使用

public class ExcelUtil 
  
   
    /**
     * Excel格式多条数据
     * @param path
     * @param data
     */
    public static void storeExcelHandlerWithMultiple (String path)
        EasyExcel.write(path)
                .head(Head()).sheet("Sheet1")
                .doWrite(dataList());
    

    private static List<List<String>> Head() 
        List<List<String>> list = new ArrayList<>();
        List<String> head0 = new ArrayList<>();
        head0.add("name");
        List<String> head1 = new ArrayList<>();
        head1.add("age");
         List<String> head2 = new ArrayList<>();
        head2.add("Date");
        
        list.add(head0);
        list.add(head1);
        list.add(head2);
        return list;
    
    private static List<List<Object>> dataList() 
        List<List<Object>> list = new ArrayList<>();
        for (int i = 0; i < 10; i++) 
            List<Object> data = new ArrayList<>();
            data.add("张三");
            data.add(25);
            data.add(new Date());
            list.add(data);
        
        return list;
    

3 基本使用

ExcelUtil.storeExcelHandlerWithMultiple(“/path/demo01.xls”);
···

这样本地就会生成demo01..xls文件，dataList() 函数复杂构造一个假数据，有4列信息。
