java利用Freemarker模板生成docx格式的word文档(全过程)

作者:互联网

参考:https://my.oschina.net/u/3737136/blog/2958421?tdsourcetag=s_pcqq_aiomsg

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>
