AutoPOI (Excel和 Word简易工具类)

AutoPOI 功能如同名字auto,追求的就是自动化,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。

当前最新版本: 1.4.3(发布日期:20220902)

反馈问题:发现bug请在github 发issue


AutoPOI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

AutoPOI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.autopoi-parent 父包--作用大家都懂得
2.autopoi 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.autopoi-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

maven

	<dependency>
	 <groupId>org.jeecgframework</groupId>
	 <artifactId>autopoi-web</artifactId>
	 <version>1.4.3</version>
	</dependency>

AutoPoi 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

AutoPoi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.SpringMvc的无缝融合 简单几句话,Excel导出搞定

	@RequestMapping(value = "/exportXls")
	public ModelAndView exportXls(HttpServletRequest request, HttpServletResponse response) {
		ModelAndView mv = new ModelAndView(new JeecgEntityExcelView());
		List<JeecgDemo> pageList = jeecgDemoService.list();
		//导出文件名称
		mv.addObject(NormalExcelConstants.FILE_NAME,"导出Excel文件名字");
		//注解对象Class
		mv.addObject(NormalExcelConstants.CLASS,JeecgDemo.class);
		//自定义表格参数
		mv.addObject(NormalExcelConstants.PARAMS,new ExportParams("自定义导出Excel模板内容标题", "自定义Sheet名字"));
		//导出数据列表
		mv.addObject(NormalExcelConstants.DATA_LIST,pageList);
		return mv;
	}
自定义视图 用途 描述
JeecgMapExcelView 实体对象导出视图 例如:List
JeecgEntityExcelView Map对象导出视图 List<Map<String, String>> list
JeecgTemplateExcelView Excel模板导出视图 -
JeecgTemplateWordView Word模板导出视图 -

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);

10.字典用法 在实体属性注解excel中添加dicCode="",此处dicCode即为jeecg系统中数据字典的Code

   @Excel(name="性别",width=15,dicCode="sex")
   private java.lang.String sex;

11.字典表用法 此处dictTable为数据库表名,dicCode为关联字段名,dicText为excel中显示的内容对应的字段

	@Excel(name="部门",dictTable="t_s_depart",dicCode="id",dicText="departname")
    private java.lang.String depart;

12.Replace用法 若数据库中存储的是0/1 ,则导出/导入的excel单元格中显示的是女/男

	@Excel(name="测试替换",width=15,replace={"男_1","女_0"})
	private java.lang.String fdReplace;

13.高级字段转换用法

  • exportConvert:在导出的时候需要替换值则配置该值为true,同时增加一个方法,方法名为原get方法名前加convert。
  • importConvert:在导入的时候需要替换值则配置该值为true,同时增加一个方法,方法名为原set方法名前加convert。
	@Excel(name="测试转换",width=15,exportConvert=true,importConvert=true)
	private java.lang.String fdConvert;
	
	/**
	  * 转换值示例: 在该字段值的后面加上元
	  * @return
	  */
	public String convertgetFdConvert(){
	  return this.fdConvert+"元";
	}
	  
	/**
	 * 转换值示例: 替换掉excel单元格中的"元"
	 * @return
	 */
	public void convertsetFdConvert(String fdConvert){
	  this.fdConvert = fdConvert.replace("元","");
	}

Excel 注解说明

@Excel

属性 类型 默认值 功能
name String null 列名,支持name_id
needMerge boolean fasle 是否需要纵向合并单元格(用于含有list中,单个的单元格,合并list创建的多个row)
orderNum String "0" 列的排序,支持name_id
replace String[] {} 值得替换 导出是{a_id,b_id} 导入反过来
savePath String "upload" 导入文件保存路径,如果是图片可以填写,默认是upload/className/ IconEntity这个类对应的就是upload/Icon/
type int 1 导出类型 1 是文本 2 是图片,3 是函数,10 是数字 默认是文本
width double 10 列宽
height double 10 列高,后期打算统一使用@ExcelTarget的height,这个会被废弃,注意
isStatistics boolean fasle 自动统计数据,在追加一行统计,把所有数据都和输出 这个处理会吞没异常,请注意这一点
isHyperlink boolean FALSE 超链接,如果是需要实现接口返回对象
isImportField boolean TRUE 校验字段,看看这个字段是不是导入的Excel中有,如果没有说明是错误的Excel,读取失败,支持name_id
exportFormat String "" 导出的时间格式,以这个是否为空来判断是否需要格式化日期
importFormat String "" 导入的时间格式,以这个是否为空来判断是否需要格式化日期
format String "" 时间格式,相当于同时设置了exportFormat 和 importFormat
databaseFormat String "yyyyMMddHHmmss" 导出时间设置,如果字段是Date类型则不需要设置 数据库如果是string 类型,这个需要设置这个数据库格式,用以转换时间格式输出
numFormat String "" 数字格式化,参数是Pattern,使用的对象是DecimalFormat
imageType int 1 导出类型 1 从file读取 2 是从数据库中读取 默认是文件 同样导入也是一样的
suffix String "" 文字后缀,如% 90 变成90%
isWrap boolean TRUE 是否换行 即支持\n
mergeRely int[] {} 合并单元格依赖关系,比如第二列合并是基于第一列 则{0}就可以了
mergeVertical boolean fasle 纵向合并内容相同的单元格
fixedIndex int -1 对应excel的列,忽略名字
isColumnHidden boolean FALSE 导出隐藏列

@ExcelCollection

属性 类型 默认值 功能
id String null 定义ID
name String null 定义集合列名,支持nanm_id
orderNum int 0 排序,支持name_id
type Class<?> ArrayList.class 导入时创建对象使用

单表导出实体注解源码

public class SysUser implements Serializable {

    /**id*/
    private String id;

    /**登录账号 */
    @Excel(name = "登录账号", width = 15)
    private String username;

    /**真实姓名*/
    @Excel(name = "真实姓名", width = 15)
    private String realname;

    /**头像*/
    @Excel(name = "头像", width = 15)
    private String avatar;

    /**生日*/
    @Excel(name = "生日", width = 15, format = "yyyy-MM-dd")
    private Date birthday;

    /**性别(1:男 2:女)*/
    @Excel(name = "性别", width = 15,dicCode="sex")
    private Integer sex;

    /**电子邮件*/
    @Excel(name = "电子邮件", width = 15)
    private String email;

    /**电话*/
    @Excel(name = "电话", width = 15)
    private String phone;

    /**状态(1:正常  2:冻结 )*/
    @Excel(name = "状态", width = 15,replace={"正常_1","冻结_0"})
    private Integer status;

一对多导出实体注解源码

public class JeecgOrderMainPage {
	
	/**主键*/
	private java.lang.String id;
	/**订单号*/
	@Excel(name="订单号",width=15)
	private java.lang.String orderCode;
	/**订单类型*/
	private java.lang.String ctype;
	/**订单日期*/
	@Excel(name="订单日期",width=15,format = "yyyy-MM-dd")
	private java.util.Date orderDate;
	/**订单金额*/
	@Excel(name="订单金额",width=15)
	private java.lang.Double orderMoney;
	/**订单备注*/
