JEasyPoi (Excel和 Word简易工具类)

EasyPOI 功能如同名字easy,追求的就是简易,让一个没接触过poi的人员,可以傻瓜化的快速实现Excel导入导出、Word模板导出、可以仅仅5行代码就可以完成Excel的导入导出。


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.ExcelImportUtil 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)

关于Excel导出XLS和XLSX区别

1.导出时间XLS比XLSX快2-3倍
2.导出大小XLS是XLSX的2-3倍或者更多
3.导出需要综合网速和本地速度做考虑^~^

几个工程的说明

1.easypoi 父包--作用大家都懂得
2.easypoi-base 导入导出的工具包,可以完成Excel导出,导入,Word的导出,Excel的导出功能
3.easypoi-web  耦合了spring-mvc 基于AbstractView,极大的简化spring-mvc下的导出功能
4.sax 导入使用xercesImpl这个包(这个包可能造成奇怪的问题哈),word导出使用poi-scratchpad,都作为可选包了

EasyPoi 模板 表达式支持

  • 空格分割
  • 三目运算 {{test ? obj:obj2}}
  • n: 表示 这个cell是数值类型 {{n:}}
  • le: 代表长度{{le:()}} 在if/else 运用{{le:() > 8 ? obj1 : obj2}}
  • fd: 格式化时间 {{fd:(obj;yyyy-MM-dd)}}
  • fn: 格式化数字 {{fn:(obj;###.00)}}
  • fe: 遍历数据,创建row
  • !fe: 遍历数据不创建row
  • $fe: 下移插入,把当前行,下面的行全部下移.size()行,然后插入
  • !if: 删除当前列 {{!if:(test)}}
  • 单引号表示常量值 '' 比如'1' 那么输出的就是 1

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 */
	private 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")
	private TeacherEntity shuxueteacher;

	@ExcelCollection(name = "选课学生", orderNum = "4")
	private List<StudentEntity> 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 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<ExcelExportEntity> entity = new ArrayList<ExcelExportEntity>();
	entity.add(new ExcelExportEntity("姓名", "name"));
	entity.add(new ExcelExportEntity("性别", "sex"));

	List<Map<String, String>> list = new ArrayList<Map<String, String>>();
	Map<String, String> map;
	for (int i = 0; i < 10; i++) {
		map = new HashMap<String, String>();
		map.put("name", "1" + i);
		map.put("sex", "2" + i);
		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<String,Object> map = new HashMap<String, Object>();
    map.put("year", "2013");
    map.put("sunCourses", list.size());
    Map<String,Object> obj = new HashMap<String, Object>();
    map.put("obj", obj);
    obj.put("name", list.size());
	params.setTemplateUrl("org/jeecgframework/poi/excel/doc/exportTemp.xls");
	Workbook book = 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 start = new Date().getTime();
	List<CourseEntity> 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,HttpServletResponse response
			, DataGrid dataGrid,ModelMap map) {

        CriteriaQuery cq = new CriteriaQuery(CourseEntity.class, dataGrid);
        org.jeecgframework.core.extend.hqlsearch.HqlGenerateUtil.installHql(cq, course, request.getParameterMap());
        List<CourseEntity> courses = this.courseService.getListByCriteriaQuery(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);
        return NormalExcelConstants.JEECG_EXCEL_VIEW;

	}

8.Excel导入校验,过滤不符合规则的数据,追加错误信息到Excel,提供常用的校验规则,已经通用的校验接口

	/**
     * Email校验
     */
    @Excel(name = "Email", width = 25)
    @ExcelVerify(isEmail = true, notNull = true)
    private String email;
    /**
     * 手机号校验
     */
    @Excel(name = "Mobile", width = 20)
    @ExcelVerify(isMobile = true, notNull = true)
    private String mobile;
    
    ExcelImportResult<ExcelVerifyEntity> result = ExcelImportUtil.importExcelVerify(new File(
            "d:/tt.xls"), ExcelVerifyEntity.class, params);
    for (int i = 0; i < result.getList().size(); i++) {
        System.out.println(ReflectionToStringBuilder.toString(result.getList().get(i)));
    }

9.导入Map 设置导入参数,传入文件或者流,即可获得相应的list,自定义Key,需要实现IExcelDataHandler接口

	ImportParams params = new ImportParams();
	List<Map<String,Object>> list = ExcelImportUtil.importExcel(new File(
			"d:/tt.xls"), Map.class, params);
