Excel和Word 简易工具类,JEasyPoi 2.1.5 版本发布
摘要:
jeasypoi 功能如同名字easy,主打的功能就是容易,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。
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
一、升级日志
- 一对多表结构导入导出BUG修正;
- jeecg 个性化定制版;
- 支持配置jeecg字典code 翻译导出;
- 支持自定义字典扩展接口,方便用户自定义;
- 大数据导入导出优化;
二、在线WIKI文档
这几篇是旧的教程,不过和现在大同小异
Excel 介绍篇 Excel 工具类 Excel 注解介绍.第一篇 Excel 注解介绍.第二篇 Excel 实体类 Word模板导出教程
后面都是新的了
三、JEasyPoi 集成方法
1. 采用 maven方式
在pom.xml 引入以下依赖。配置私服http://maven.jeecg.org/nexus/
<dependency>
<groupId>org.jeecgframework</groupId>
<artifactId>jeasypoi-base</artifactId>
<version>2.1.5</version>
</dependency>
<dependency>
<groupId>org.jeecgframework</groupId>
<artifactId>jeasypoi-web</artifactId>
<version>2.1.5</version>
</dependency>
<dependency>
<groupId>org.jeecgframework</groupId>
<artifactId>jeasypoi-annotation</artifactId>
<version>2.1.5</version>
</dependency>
2. 非maven方式
直接拷贝相关jar进项目Lib中
四、源码下载

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);
