nmyphp / util-excel

Java对象与Excel文件之间的转换工具

功能

包装Apache-pio API对外提供以下静态方法：

• 将Java实体集合转成Excel文档
• Excel文件转成Java对象集合

快速开始

• Java 转 Excel

  // 指定excel列和对象属性的对应关系
  excelColumns.add(new ExcelColumn("id", "编号"));
  excelColumns.add(new ExcelColumn("name", "姓名"));
  excelColumns.add(new ExcelColumn("sex", "性别"));
  excelColumns.add(new ExcelColumn("age", "年龄"));
  excelColumns.add(new ExcelColumn("score", "分数"));
  // 构造一些User对象供测试
  List<User> users = new ArrayList<>();
  users.add(new User(1L, "张小敬", '男', 35, 98.8d));
  users.add(new User(1L, "闻染", '女', 25, 92.5d));
  
  ExcelUtil.object2Excel(excelColumns, users, "/Users/nmyphp/User.xlsx");

  运行后在指定目录/Users/nmyphp/User.xlsx生成如下excel文件如下：

  

• Excel 转 Java

  // 指定excel列和对象属性的对应关系
  ExcelHead excelHead = new ExcelHead();
  excelColumns.add(new ExcelColumn("id", "编号"));
  excelColumns.add(new ExcelColumn("name", "姓名"));
  excelColumns.add(new ExcelColumn("sex", "性别"));
  excelColumns.add(new ExcelColumn("age", "年龄"));
  excelHead.setColumns(excelColumns);
  
  List<User> transResult = ExcelUtil.excel2Object("/Users/nmyphp/User.xlsx", excelHead, User.class);
  // 输出
  System.out.println(new Gson().toJson(transResult));

  运行后输出Json如下：

  [
      {
          "id":1,
          "name":"张小敬",
          "sex":"男",
          "age":35,
          "score":98.8
      },
      {
          "id":1,
          "name":"闻染",
          "sex":"女",
          "age":25,
          "score":92.5
      },
      {
          "id":1,
          "name":"龙泽",
          "sex":"男",
          "age":38,
          "score":100
      }
  ]
