pdf开发文档（快速Office,PDF 开发 工具 EasyPoi）

easypoi 功能如同名字easy,主打的功能就是易容,让一个没见接触过poi的人员 就可以方便的写出Excel导出,Excel模板导出,Excel导入,Word模板导出,通过简单的注解和模板 语言(熟悉的表达式语法),完成以前复杂的写法

EasyPoi的主要特点

1.设计精巧,使用简单 2.接口丰富,扩展简单 3.默认值多,write less do more 4.AbstractView 支持,web导出可以简单明了

EasyPoi的几个入口工具类

1.ExcelExportUtil Excel导出(普通导出,模板导出) 2.Exc大流量卡elImportUtil Excel导入 3.WordExportUtil Word导出(只支持docx ,doc版本poi存在图片的bug,暂不支持)

版本修改

2.0.6-SNAPSHOT增加map的导出增加index 列

EasyPoi导出实例

1.注解,导入导出都是基于注解的,实体上做上注解,标示导出对象,同时可以做一些操作

@ExcelTarget(“courseEntity”) public class CourseEntity implements java.io.Serializable { /** 主键 */ privat大流量卡e String id; /** 课程名称 */ @Excel(name = “课程名称”, orderNum = “1”, needMerge = true) private String name; /** 老师主键 */ @ExcelEntity(id = “yuwen”) @ExcelVerify() private TeacherEntity teacher; /** 老师主键 */ @ExcelEntity(id = “shuxue”) 大流量卡 private TeacherEntity shuxueteacher; @ExcelCollection(name = “选课学生”, orderNum = “4”) private List students;

2.基础导出 传入导出参数,导出对象,以及对象列表即可完成导出

HSSFWorkbook workbook = ExcelExportUtil.exportExcel(new ExportParams( “2412312”, “测试”, “测试”), CourseEntity.class, list);

3.基础导出,带有索引大流量卡 在到处参数设置一个值,就可以在导出列增加索引

ExportParams params = new ExportParams(“2412312”, “测试”, “测试”); params.setAddIndex(true); HSSFWorkbook workbook = ExcelExportUtil.exportExcel(params, TeacherEntity.class, telist);

4.导出Map 创建类似注解的集合,即可完成Map的导出,略有麻烦

List entity = new ArrayList(); ent大流量卡ity.add(new ExcelExportEntity(“姓名”, “name”)); entity.add(new ExcelExportEntity(“性别”, “sex”)); List> list = new ArrayList>(); Map map; for (int i = 0; i < 10; i++) { map = new HashMap(); map.put(“name”, “1” + i); map.put(“sex”, “2” + i); 大流量卡 list.add(map); } HSSFWorkbook workbook = ExcelExportUtil.exportExcel(new ExportParams( “测试”, “测试”), entity, list);

5.模板导出 根据模板配置,完成对应导出

TemplateExportParams params = new TemplateExportParams(); params.setHeadingRows(2); params.setHeadingStartRow(2); Map大流量卡 map = new HashMap(); map.put(“year”, “2013”); map.put(“sunCourses”, list.size()); Map obj = new HashMap(); map.put(“obj”, obj); obj.put(“name”, list.size()); params.setTemplateUrl(“org/jeecgframework/poi/excel/doc/exportTemp.xls”); Workbook bo大流量卡ok = ExcelExportUtil.exportExcel(params, CourseEntity.class, list, map);

6.导入 设置导入参数,传入文件或者流,即可获得相应的list

ImportParams params = new ImportParams(); params.setTitleRows(2); params.setHeadRows(2); //params.setSheetNum(9); params.setNeedSave(true); long star大流量卡t = new Date().getTime(); List list = ExcelImportUtil.importExcel(new File( “d:/tt.xls”), CourseEntity.class, params);

7.和spring mvc的无缝融合 简单几句话,Excel导出搞定

@RequestMapping(params = “exportXls”) public String exportXls(CourseEntity course,HttpServletRequest request,HttpServletResp大流量卡onse response , DataGrid dataGrid,ModelMap map) { CriteriaQuery cq = new CriteriaQuery(CourseEntity.class, dataGrid); org.jeecgframework.core.extend.hqlsearch.HqlGenerateUtil.installHql(cq, course, request.getParameterMap()); List courses = this.courseService.getListB大流量卡yCriteriaQuery(cq,false); map.put(NormalExcelConstants.FILE_NAME,”用户信息”); map.put(NormalExcelConstants.CLASS,CourseEntity.class); map.put(NormalExcelConstants.PARAMS,new ExportParams(“课程列表”, “导出人:Jeecg”, “导出信息”)); map.put(NormalExcelConstants.DATA_LIST,courses大流量卡); return NormalExcelConstants.JEECG_EXCEL_VIEW; }
