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：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | < w:p wsp:rsidR = "00D02906" wsp:rsidRDefault = "00FA4C58" wsp:rsidP = "00FA4C58" > < w:pPr > < w:jc w:val = "center" /> < w:rPr > < w:rFonts w:hint = "fareast" /> </ w:rPr > </ w:pPr > < w:r > < w:t >${year}</ w:t > </ w:r > < w:r > < w:rPr > < wx:font wx:val = "宋体" /> </ w:rPr > < w:t >年度工作报告</ w:t > </ w:r >< span style = "line-height:22px;font-family:'Courier New';" class = "Apple-style-span" >< span style = "color:#0000ff;" ></</ span >< span style = "color:#800000;" >w:p</ span >< span style = "color:#0000ff;" >></ span ></ span > |

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：
只要将base64的代码替换成例如：${image}，如下：
这里要注意“>${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：
