java根据模板导出word，并在word中插入echarts相关统计图片
java根据word模板生成对应的word文档，并且要在word文档中插入Echarts的一些统计图表，例如柱状图、折线图、柱状混合图等。思路是根据Echatrs的option生成json文件，然后通过命令行调用phantomjs执行echarts-convert的js脚本生成Echarts对应图表的图片，然后将图片转为Base64的字符串，替换word文档中的图片占位符，实现往word文档中插入统计图表的需求。

创建word模板
创建ftl模板文件
首先使用word创建一个doc文件，其中的主要字段全部用${param}占位符替换，示例如下：
然后将doc模板另存为xml
重命名为ftl文件。
保存的ftl可能会出现占位符分割的问题，需要处理
import cn.hutool.core.io.FileUtil;
import cn.hutool.core.io.file.FileAppender;
import cn.hutool.core.io.file.FileReader;
import java.util.List;
/**
* 将分离的占位符去除、变量值重新拼装
*/
public class formatXml {
public static void main(String[] args) {
//文件读取-FileReader
//默认UTF-8编码，可以在构造中传入第二个参数作为编码 原始ftl文件
FileReader fileReader = new FileReader("C:\\Users\\Desktop\\jijiaritemp11.ftl");
//从文件中读取每一行数据
List<String> strings = fileReader.readLines();
//文件追加-FileAppender
//destFile – 目标文件
//capacity – 当行数积累多少条时刷入到文件
//isNewLineMode – 追加内容是否为新行
FileAppender appender = new FileAppender(FileUtil.newFile("C:\\Users\\Desktop\\jiejiaritemp.ftl"), 16, true);
//遍历得到每一行数据
for (String string : strings) {
//判断每一行数据中不包含'$'的数据先添加进新文件
if (!string.contains("$")) {
appender.append(string);
continue;
}
//如果一行数据中包含'$'变量符将替换为'#$'
string = string.replaceAll("\\$", "#\\$");
//然后以'#'切割成每一行（数组）,这样一来'$'都将在每一行的开头
String[] ss = string.split("#");
// 同一行的数据写到同一行,文件追加自动换行了(最后的完整数据)
StringBuilder sb = new StringBuilder();
//遍历每一行（数组ss）
for (int i = 0; i < ss.length; i++) {
//暂存数据
String s1 = ss[i];
//将不是以'$'开头的行数据放进StringBuilder
if (!s1.startsWith("$")) {
sb.append(s1);
continue;
}
//被分离的数据一般都是'${'这样被分开
//匹配以'$'开头的变量找到'}' 得到索引位置
int i1 = s1.lastIndexOf("}");
//先切割得到这个完整体
String substr = s1.substring(0, i1 + 1);
//把变量追加到StringBuilder
sb.append(substr.replaceAll("<[^>]+>", ""));
//再将标签数据追加到StringBuilder包裹变量
sb.append(s1.substring(i1 + 1));
}
appender.append(sb.toString());
}
appender.flush();
appender.toString();
}
}
将ftl文件中的图片的Base64删除，并使用占位符代替
搜索<w:binData标签，删除Base64字符串，使用占位符代替
这样，word模板文件ftl就创建好了，只需组装数据即可。

这里需要替换JSpath为echarts-convert1.js的路径、phantomjs.exe的路径。
对于echarts的optiona，可以先在 echarts官网上找到对应的统计图表，然后调整好样式后复制到代码中，主要参数需要替换为真实数据。
