更新時間：2025年06月11日 10:59:30 作者：cccl.

這篇文章主要為大家詳細介紹了java導出Echarts圖表的示例代碼,包括柱狀圖,餅形圖,折線圖等,文中的示例代碼講解詳細,感興趣的小伙伴可以了解下

1、Apache POI依賴

代碼如下所示：

<dependencies>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>4.1.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml-schemas</artifactId>
        <version>4.1.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>4.1.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-scratchpad</artifactId>
        <version>4.1.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.xmlbeans</groupId>
        <artifactId>xmlbeans</artifactId>
        <version>3.1.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>ooxml-schemas</artifactId>
        <version>1.4</version>
    </dependency>

2、導出word報告Controller

  @ApiOperation(value = "導出word報告", notes = "導出word報告")
   @GetMapping("/exportWord")
   public void exportWord(HttpServletResponse response) throws Exception {
      XWPFDocument word = commonService.exportWord();
         try {
             response.setHeader("Content-disposition",
            "attachment;filename=" + new String("analysis_report.doc".getBytes(), "utf-8"));
              response.setContentType("application/x-msdownload");
               OutputStream os = response.getOutputStream();
                 word.write(os);
                 os.close();
        } catch (IOException e) {
            logger.info("文件下載出錯！");
        }
    }

3、service

//導出word報告
XWPFDocument  exportWord() throws Exception;

4、servicelmpl

package com.iecas.satresource.service.impl;
import org.apache.poi.util.Units;
import org.apache.poi.xddf.usermodel.chart.*;
import org.apache.poi.xwpf.usermodel.XWPFChart;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import java.io.FileOutputStream;
@Override
public XWPFDocument exportWord() {
    // 1、創(chuàng)建word文檔對象
    XWPFDocument doc = new XWPFDocument();
    XWPFParagraph para;
    XWPFRun run;
     //2.// x軸標題
     String name = " ";
      // 3、X軸(分類軸)數(shù)據(jù)
   String[] xAxisData = new String[] {
            "2022-01","2022-02","2022-03","2022-04","2022-05","2022-06",
            "2022-07","2022-08","2022-09","2022-10","2022-11","2022-12",
    };
        yAxis.setTitle("流量（個）"); // Y軸標題
    yAxis.setCrossBetween(AxisCrossBetween.BETWEEN); // 設置圖柱的位置:BETWEEN居中
     // 4、y軸數(shù)據(jù)
    Integer[] yAxisData = new Integer[]{
            20, 37, 21, 75, 79, 118,
            29, 112, 51, 85, 101, 89
    };
 //如一次性導出多個ECharts柱形圖可創(chuàng)建多個方法進行調(diào)用創(chuàng)建,如果數(shù)據(jù)類型不一樣可在創(chuàng)建工具類創(chuàng)建多個方法進行調(diào)用
    wordUtil.WordReadZc(doc, xAxisDate, yAxisDat4, name);
    return doc;
    }

5、工具類

package com.iecas.satresource.utils;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.util.Units;
import org.apache.poi.xddf.usermodel.chart.*;
import org.apache.poi.xwpf.usermodel.XWPFChart;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

import java.io.IOException;

/**
 * 導出ECharts柱形圖
 */
public class WordUtil {
 XWPFChart chart = null;
  public XWPFChart WordRead(XWPFDocument doc, String[] xAxisDate, Integer[] yAxisDate, String name) {
      try {
        this.chart = doc.createChart(5400000, 3600000);
    } catch (InvalidFormatException var15) {
        var15.printStackTrace();
    } catch (IOException var16) {
        var16.printStackTrace();
    }

    this.chart.setTitleOverlay(false);
    XDDFChartLegend legend = this.chart.getOrAddLegend();
    legend.setPosition(LegendPosition.TOP);
    XDDFCategoryAxis xAxis = this.chart.createCategoryAxis(AxisPosition.BOTTOM);
    //標題名稱
    xAxis.setTitle(name);
    //x數(shù)據(jù)
    XDDFCategoryDataSource xAxisSource = XDDFDataSourcesFactory.fromArray(xAxisDate);
    XDDFValueAxis yAxis = this.chart.createValueAxis(AxisPosition.LEFT);
    yAxis.setCrossBetween(AxisCrossBetween.BETWEEN);
    XDDFBarChartData barChart;
    Series barSeries;
    //y數(shù)據(jù)
      XDDFNumericalDataSource<Integer> yAxisSource1 = XDDFDataSourcesFactory.fromArray(yAxisDate);
        barChart = (XDDFBarChartData)this.chart.createData(ChartTypes.BAR, xAxis, yAxis);
        barChart.setBarDirection(BarDirection.COL);
        barSeries = (Series)barChart.addSeries(xAxisSource, yAxisSource1);
        barSeries.setTitle("", (CellReference)null);
        this.chart.plot(barChart);
            return this.chart;
  }
}
