easyexcel 列头合并_Easyexcel使用文档及动态列的实现

發(fā)布時(shí)間：2024/8/23 46 豆豆

生活随笔收集整理的這篇文章主要介紹了 easyexcel 列头合并_Easyexcel使用文档及动态列的实现小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

Java解析、生成Excel比較有名的框架有Apache poi、jxl。但他們都存在一個(gè)嚴(yán)重的問題就是非常的耗內(nèi)存，poi有一套SAX模式的API可以一定程度的解決一些內(nèi)存溢出的問題，但POI還是有一些缺陷，比如07版Excel解壓縮以及解壓后存儲都是在內(nèi)存中完成的，內(nèi)存消耗依然很大。easyexcel重寫了poi對07版Excel的解析，能夠原本一個(gè)3M的excel用POI sax依然需要100M左右內(nèi)存降低到KB級別，并且再大的excel不會出現(xiàn)內(nèi)存溢出，03版依賴POI的sax模式。在上層做了模型轉(zhuǎn)換的封裝，讓使用者更加簡單方便。

我建議大家使用1.1.2-beta4版本，也就是官方給的最新版，maven倉庫查到的最新版比這個(gè)版本略低，最顯著的區(qū)別就是excel中數(shù)字的輸出，最新版本到處excel會將數(shù)字專為數(shù)字格式，而maven庫給出的最新版則會輸出成文本格式。其他變化需要各位自己去發(fā)現(xiàn)。

1.1.2-beta4

使用方法

1.表頭帶注解方法

這種方法首先需要一個(gè)繼承BaseRowModel的模型，在Hap框架dto的角色就相當(dāng)于這個(gè)模型，示例如下

package ect.report.dto;

import com.alibaba.excel.annotation.ExcelProperty;

import com.alibaba.excel.metadata.BaseRowModel;

import java.math.BigDecimal;

import java.util.Date;

/**

* @ClassName: TraBilDetail

* @Description: TODO

* @Date: 2019-03-29 09:52

* @Version 1.0

public class TraBilDetail extends BaseRowModel {

//開票申請?zhí)?/p>

@ExcelProperty(value = {"開票申請?zhí)?#34;}, index = 0)

private String applyNum;

//批次號

@ExcelProperty(value = {"批次號"}, index = 1)

private String batchNum;

//制單部門

@ExcelProperty(value = {"制單部門"}, index = 2)

private String name;

//客戶名稱

@ExcelProperty(value = {"客戶名稱"}, index = 3)

private String custName;

//業(yè)務(wù)類型

@ExcelProperty(value = {"業(yè)務(wù)類型"}, index = 4)

private String busiType;

//批次開票金額

@ExcelProperty(value = {"批次開票金額"}, index = 5)

private BigDecimal sumPrice;

//批次開票重量

@ExcelProperty(value = {"批次開票重量"}, index = 6)

private BigDecimal invoWeight;

//批次財(cái)務(wù)入總金額

@ExcelProperty(value = {"批次財(cái)務(wù)入總金額"}, index = 7)

private BigDecimal findInAmoundSum;

//郵寄信息

@ExcelProperty(value = {"郵寄信息"}, index = 8)

private String mailAddress;

private String contactName;

private String telephone;

/*=========================== 查詢字段================================*/

private Long comId;

private Date applyDateStart;

private Date applyDateEnd;

/*=====================================*/

get和set方法省略

/*=====================================*/

}

然后mapper.java,Service.java,～ServiceImpl.java都要去掉繼承系統(tǒng)框架的base接口。mapper層寫好查詢出需要展示的數(shù)據(jù)，dto的注解中字段對應(yīng)的顯示。上述例子寫的是單層頭結(jié)構(gòu)，如果想要寫成雙層或者多層，可以想一下示例一樣添加。

package ect.report.dto;

import com.alibaba.excel.annotation.ExcelProperty;

import com.alibaba.excel.metadata.BaseRowModel;

import java.math.BigDecimal;

/**

* @ClassName: BatchSupply

* @Description: TODO

* @Date: 2019-04-02 09:00

public class BatchSupply extends BaseRowModel {

private String comName;

//倉庫名稱

@ExcelProperty(value = {"在庫貨源","倉庫名稱"} ,index = 1)

private String subinvName;

//產(chǎn)地

@ExcelProperty(value = {"在庫貨源","產(chǎn)地"} ,index = 2)

private String terrName;

//等級

@ExcelProperty(value = {"在庫貨源","等級"} ,index = 3)

private String ctLevel;

//長度

@ExcelProperty(value = {"在庫貨源","長度"} ,index = 4)

private String length;

//長度均值

@ExcelProperty(value = {"在庫貨源","長度均值"} ,index = 5)

private String lengthMean;

//馬值

@ExcelProperty(value = {"在庫貨源","馬值"} ,index = 6)

private String micron;

@ExcelProperty(value = {"在庫貨源","提單號"} ,index = 10)

private String blNum;

//入庫單號

@ExcelProperty(value = {"在庫貨源","入庫單號"} ,index = 11)

private String entryNum;

//箱號

@ExcelProperty(value = {"在庫貨源","箱號"} ,index = 12)

private String batchNum;

//入庫件數(shù)

@ExcelProperty(value = {"在庫貨源","入庫件數(shù)"} ,index = 13)

private BigDecimal batchQty;

//銷售合同號

@ExcelProperty(value = {"在庫貨源","銷售合同號"} ,index = 14)

private String conNum;

//出庫單號

@ExcelProperty(value = {"在庫貨源","出庫單號"} ,index = 15)

private String outNum;

//出庫件數(shù)

@ExcelProperty(value = {"在庫貨源","出庫件數(shù)"} ,index = 16)

private BigDecimal outBatchQty;

//在庫箱數(shù)

@ExcelProperty(value = {"在庫貨源","在庫箱數(shù)"} ,index = 17)

private String outStatus;

//在庫件數(shù)

@ExcelProperty(value = {"在庫貨源","在庫件數(shù)"} ,index = 18)

private BigDecimal wareQty;

//采購合同單價(jià)

@ExcelProperty(value = {"在庫貨源","采購合同單價(jià)"} ,index = 19)

private BigDecimal conPrice;

//財(cái)務(wù)入庫成本

@ExcelProperty(value = {"在庫貨源","財(cái)務(wù)入庫成本"} ,index = 20)

private BigDecimal finaPrice;

//初始財(cái)務(wù)入庫成本(USD)

@ExcelProperty(value = {"在庫貨源","財(cái)務(wù)入庫成本"} ,index = 21)

private BigDecimal firstUsdPrice;

//初始財(cái)務(wù)入庫成本(CNY)

@ExcelProperty(value = {"在庫貨源","初始財(cái)務(wù)入庫成本"} ,index = 22)

private BigDecimal firstRmbPrice;

private String lengthMax;

private String lengthMin;

private String micronMax;

private String micronMin;

private String strongMax;

private String strongMin;

private String terrCode;

private String comCode;

private String subinvId;

private String isBatchFlag;

private Long specId;

/*=====================================*/

get和set方法省略

/*=====================================*/

}

然后在Service層組裝業(yè)務(wù)邏輯并且輸出excel文檔。

package ect.report.service.impl;

import com.alibaba.excel.ExcelWriter;

import com.alibaba.excel.metadata.Sheet;

import com.alibaba.excel.support.ExcelTypeEnum;

import ect.inv.util.StringUtils;

import ect.report.dto.TraBilDetail;

import ect.report.mapper.TraBilDetailMapper;

import ect.report.utils.EasyEacelUtils;

import jodd.util.StringUtil;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import ect.report.service.ITraBilDetailService;

import org.springframework.transaction.annotation.Transactional;

import javax.servlet.ServletOutputStream;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

import java.util.List;

/**

* @ClassName: TraBilDetailServiceImpl

* @Description: TODO

* @Date: 2019-03-29 09:53

* @Version 1.0

@Service

@Transactional(rollbackFor = Exception.class)

public class TraBilDetailServiceImpl implements ITraBilDetailService{

@Autowired

private TraBilDetailMapper traBilDetailMapper;

@Override

public void export(HttpServletRequest request, TraBilDetail traBilDetail, HttpServletResponse httpServletResponse) throws IOException {

String fileName="內(nèi)貿(mào)開票明細(xì)表";

//組裝輸出流

ServletOutputStream outputStream = EasyEacelUtils.createOutputStream(request, httpServletResponse, fileName);

try {

ExcelWriter writer = new ExcelWriter(outputStream, ExcelTypeEnum.XLSX);

Sheet sheet1 = new Sheet(1, 0, TraBilDetail.class);

//自適應(yīng)寬度

sheet1.setAutoWidth(Boolean.TRUE);

//添加數(shù)據(jù)

writer.write(traBilDetailMapper.selectTraBilDetail(traBilDetail), sheet1);

writer.finish();

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

outputStream.close();

} catch (IOException e) {

e.printStackTrace();

}

這樣一個(gè)非常簡單的excel導(dǎo)出就完成了，這種方法適合于常規(guī)的excle導(dǎo)出。如果sql查詢的數(shù)據(jù)還不能瞞住需求，需要Java中繼續(xù)添加業(yè)務(wù)邏輯的話，可以繼續(xù)組裝成一個(gè)返回List的方法。示例如下

官方示例dome

ExcelWriter writer = EasyExcelFactory.getWriterWithTemp(inputStream,out,ExcelTypeEnum.XLSX,true);

//寫第一個(gè)sheet, sheet1 數(shù)據(jù)全是List 無模型映射關(guān)系

Sheet sheet1 = new Sheet(1, 3);

sheet1.setSheetName("第一個(gè)sheet");

//設(shè)置列寬設(shè)置每列的寬度

Map columnWidth = new HashMap();

columnWidth.put(0,10000);columnWidth.put(1,40000);columnWidth.put(2,10000);columnWidth.put(3,10000);

sheet1.setColumnWidthMap(columnWidth);

sheet1.setHead(createTestListStringHead());

//or 設(shè)置自適應(yīng)寬度

//sheet1.setAutoWidth(Boolean.TRUE);

writer.write1(createTestListObject(), sheet1);

//寫第二個(gè)sheet sheet2 模型上打有表頭的注解，合并單元格

Sheet sheet2 = new Sheet(2, 3, JavaModel1.class, "第二個(gè)sheet", null);

sheet2.setTableStyle(createTableStyle());

writer.write(createTestListJavaMode(), sheet2);

//寫第三個(gè)sheet包含多個(gè)table情況

Sheet sheet3 = new Sheet(3, 0);

sheet3.setSheetName("第三個(gè)sheet");

Table table1 = new Table(1);

table1.setHead(createTestListStringHead());

writer.write1(createTestListObject(), sheet3, table1);

//寫sheet2 模型上打有表頭的注解

Table table2 = new Table(2);

table2.setTableStyle(createTableStyle());

table2.setClazz(JavaModel1.class);

writer.write(createTestListJavaMode(), sheet3, table2);

//關(guān)閉資源

writer.finish();

out.close();

2.表頭不帶注解的方法

這種dto的寫法跟上述的dto寫法基本相同，就是去掉了注解。也可以不用dto，直接用List來代替dto的作用，其他都一樣。表頭帶注解的方法不用自己寫表頭，不帶注解的方法需要自己去組裝表頭，但是這種方法可以去調(diào)整表頭字段的寬度。帶注解的方法表頭會自適應(yīng)一個(gè)寬度出來。

總結(jié)

以上舉例是常用的兩種組裝數(shù)據(jù)成excel的方法，第一種適用常規(guī)的excel導(dǎo)出，但是表頭不能控制，數(shù)據(jù)也必須跟dto中對應(yīng)，限制相對大一點(diǎn)。第二種方法靈活行比較大，表頭可以自己組裝，數(shù)據(jù)也不用局限dto。在實(shí)際運(yùn)用中就最大的不同就是第二種可以做動態(tài)列，但是由于第一種因?yàn)槠渚窒扌跃蜔o法完成動態(tài)列的實(shí)現(xiàn)，但是它卻省了很多功夫來組裝數(shù)據(jù)。兩者各有優(yōu)劣，就看實(shí)際的業(yè)務(wù)需求了。

當(dāng)然還有同一個(gè)sheet中使用table來實(shí)現(xiàn)兩部分?jǐn)?shù)據(jù)塊的展示方法等等，這些都可以從官方文檔中找個(gè)具體的使用方法。這里就不做詳細(xì)闡述了，本文主要就是講解數(shù)據(jù)的組裝邏輯方法。
