java使用poi在word中生成柱状图、折线图、饼图、柱状图 及替换word文档里的动态变量

本文主要是介绍java使用poi在word中生成柱状图、折线图、饼图、柱状图 及替换word文档里的动态变量,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

感谢以下博客

1.java使用poi操作world生成饼图,柱状图,折线图,组合图:二_不知所终的博客-CSDN博客2.java使用poi在word中生成柱状图、折线图、饼图、柱状图+折线图组合图、动态表格、文本替换、图片替换、更新内置Excel数据、更新插入的文本框内容、合并表格单元格;_u014427811的博客-CSDN博客

本文参考以上两个博客,并做了部分修改做了记录

解决的问题

1.填充数据后,图例却没动态改变,还是模板里的图例。

数据分析时,需要往图形缓存里赋值图例标题

 

2.动态删除图表,如有要求,图表没有数据时动态删除图表。

通过图形所在段落位置删除的,没找到其他方法。

图形的位置是通过一段文字位置的找到,比如我的图形在“1)到访游客规模”下面,我先找到这个文字的位置,文字的位置+1就是我图形的位置。哈哈,有点牵强,但是没找到其他办法。

 

 获取图片的位置

private Integer getParagraphIndex(List<XWPFParagraph> xwpfParagraphList,String mark) {
        for (int i=0;i<xwpfParagraphList.size();i++){
            XWPFParagraph paragraph=xwpfParagraphList.get(i);
            List<XWPFRun> xwpfRuns= paragraph.getRuns();
            String runStr="";
            for (int z=0; z<xwpfRuns.size(); z++) {
                runStr+=xwpfRuns.get(z).toString();
            }
            if(mark.equals(runStr)){
                return i+1;
            }
        }
        return null;
    }

 

3.假如我们模板某个折线图有四条数据,但实际我们填充的数据只填充了两条,最后生成的图表里会有四条数据,前两条就是我们实际的数据,后两条我们填充数据,模板数据却保留了。

新增图标数据前,先删除调模板里边的数据,不知道为啥滴倒着删,正着顺序会乱。。。 

1.准备一个简单的word模板,后缀名为.docx

 

2.上代码

测试类

说明:dataSource是数据源,可通过调接口获取json格式数据

           wordTemplete可配置系统参数里,定义图标位置及类型等,可动态改变word模板里的图形,不用改动代码。
