自定义载入模板

1. 用word写一个需要导出的word模板，然后存为xml格式。

2. 将xml中需要动态修改内容的地方，换成freemarker的标识符，例如：

         <w:pPr>
             <w:jcw:val="center"/>
             <w:rPr>
                 <w:rFontsw:hint="fareast"/>
             </w:rPr>
         </w:pPr>
         <w:r>
             <w:t>${year}</w:t>
         </w:r>
         <w:r>
             <w:rPr>
                 <wx:fontwx:val="宋体"/>
             </w:rPr>
             <w:t>年度工作报告</w:t>
         </w:r><spanstyle="line-height:22px;font-family:'Courier New';"class="Apple-style-span"><spanstyle="color:#0000ff;"></</span><spanstyle="color:#800000;">w:p</span><spanstyle="color:#0000ff;">></span></span>

3. 用代码生成：

添加图片

如果你需要在word中添加图片，那你就在第一步制作模板时，加入一张图片占位，然后打开xml文档，可以看到如下的一片base64编码后的代码：

1 <w:binData w:name="wordml://03000001.png" xml:space="preserve">iVBORw0…(很省略很省略)…CC</w:binData>

只要将base64的代码替换成例如：${image}，如下：

1 <w:binData w:name="wordml://03000001.png" xml:space="preserve">${image}</w:binData>

这里要注意“>${image}<”这尖括号中间不能加任何其他的诸如空格，tab，换行等符号。

然后用代码生成：
