现在要导出格式如下: ![](https://img.kancloud.cn/45/bb/45bb65225982b10f9689c666382659e5_318x493.png) 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); ~~~
