现在要导出格式如下:
实体如下:
- public class TestEntity{
- @Excel(name = "姓名", width = 15)
- private String username;
- @Excel(name = "年龄", width = 15)
- private int age;
- .....省略后续getset
数据格式如下:
- //多个map,对应了多个sheet
- List<Map<String, Object>> listMap = new ArrayList<Map<String, Object>>();
- for(int i=0;i<3;i++){
- Map<String, Object> map = new HashMap<String, Object>();
- map.put("title",getExportParams("测试"+i));//表格title
- map.put("entity",TestEntity.class);//表格对应实体
- //数据封装方式一:map数据,手动封装ExcelExportEntity集合
- List<Map> ls=new ArrayList<Map> ();
- for(int j=0;j<10;j++){
- Map map = new HashMap();
- map1.put("name","李四"+j);
- map1.put("age",18+j);
- ls.add(map);
- }
- //数据封装方式二:实体类
- List<TestEntity> ls=new ArrayList<TestEntity> ();
- for(int j=0;j<10;j++){
- TestEntity testEntity = new TestEntity();
- testEntity.setName("张三"+j);
- testEntity.setAge(18+j);
- ls.add(testEntity);
- }
- map.put("data", ls);
- listMap.add(map);
- }
- //导出参数
- public static ExportParams getExportParams(String name) {
- //表格名称,sheet名称,导出版本
- return new ExportParams(name,name,ExcelType.XSSF);
- }
调用ExcelExportUtil.exportExcel方法生成workbook
- Workbook wb = ExcelExportUtil.exportExcel(listMap,ExcelType.XSSF);
