具体思路
1.创建一个docx文档模板,其中的英文是根据自己需要填充的内容。
2.把docx文档修改为ZIP格式(修改.docx后缀名为.zip),然后把zip解压到当前目录
3.修改word目录下document.xml文档,把如下原来是time改为${time},改好后放入项目中,用于后边内容填充。【有时候一个单词可能会被拆分,自己要做相应的调整】
<#list minuteList as minute></#list> 可用于循环填充,相当于 for (Minute minte:minuteList),示列如下:
<#list minuteList as minute> <w:p w14:paraId="3BB7AF6B" w14:textId="2AD2E958" w:rsidR="00D80192" w:rsidRDefault="00C4552D" w:rsidP="00E47882"> <w:pPr> <w:pStyle w:val="a6"/> <w:numPr> <w:ilvl w:val="0"/> <w:numId w:val="2"/> </w:numPr> <w:ind w:firstLineChars="0"/> </w:pPr> <w:proofErr w:type="spellStart"/> <w:r w:rsidRPr="00C4552D"> <w:t>${minute.meeting_decision_content}</w:t> </w:r> <w:proofErr w:type="spellEnd"/> <w:r> <w:t xml:space="preserve"> </w:t> </w:r> <w:bookmarkStart w:id="0" w:name="_GoBack"/> <w:bookmarkEnd w:id="0"/> <w:r> <w:rPr> <w:rFonts w:hint="eastAsia"/> </w:rPr> <w:t>交由</w:t> </w:r> <w:proofErr w:type="spellStart"/> <w:r w:rsidRPr="00C4552D"> <w:t>${minute.meeting_decision_executor} </w:t> </w:r> <w:proofErr w:type="spellEnd"/> <w:r> <w:rPr> <w:rFonts w:hint="eastAsia"/> </w:rPr> <w:t>负责,在</w:t> </w:r> <w:proofErr w:type="spellStart"/> <w:r w:rsidRPr="00C4552D"> <w:t>${minute.meeting_decision_deadline} </w:t> </w:r> <w:proofErr w:type="spellEnd"/> <w:r> <w:rPr> <w:rFonts w:hint="eastAsia"/> </w:rPr> <w:t>前完成。</w:t> </w:r> </w:p> </#list>
---------下边思路在代码中实现------------
4..把内容填充到document.xml里
5.在输入docx文档的时候把填充过内容的的 document.xml用流的方式写入zip(详见下面代码)。
6.输出docx文档
docx模板修改成zip格式后的信息如下(因为word文档本身就是ZIP格式实现的)
注:【在文档里边加入图片须进行rels文档的相关操作,我这里没用到,如有需要可以查看上边的参考链接】
---------代码部分------------
pom中导入依赖:
<dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> </dependency>
