FreeMarker生成word

FreeMarker生成word数据填充是经过,Map填充。java

Map dataMap = new HashMap<String, Object>();数据库

List<User> list=new List<User>();apache

dataMap.put("title", "测试");dom

dataMap.put("listUser",list);工具

步骤1：测试

   编辑word模块，模板配置好后。另存为word 2003 XML格式，并选择“仅保存数据”。lua

步骤2：spa

   将生成好的xml打开，里面的内容复制到新建的ftl文件，将ftl文件放到项目中做为模板.net

步骤3：code

打开ftl文件，替换要填充的数据  如要提货 “Fan” 打开后输入  ${userName},”userName“是Map里面的key的名字，freemarker数据填充是经过Map的

FTL模板：

if语句使用：

根据条件展现某一块的数据

<#if (AllNetWork="true")>
                <w:p wsp:rsidR="00A635F3" wsp:rsidRDefault="00A635F3" wsp:rsidP="00A635F3">
                    <w:pPr>
                        <w:pStyle w:val="1" />
                        <w:listPr>
                            <w:ilvl w:val="0" />
                            <w:ilfo w:val="2" />
                            <wx:t wx:val="一、" />
                            <wx:font wx:val="Times New Roman" />
                        </w:listPr>
                        <w:ind w:first-line-chars="0" />
                        <w:outlineLvl w:val="1" />
                    </w:pPr>

</#if>

非空判断

${time!}

<#if rscpList.startTime??>
    ${rscpList.startTime?string('yyyy-MM-dd HH:mm:ss')}
</#if>

图片插入：image二进制图片流

<w:pict>
<w:binData w:name="wordml://03000001.jpg">${image}</w:binData>
<v:shape id="_x0000_i1025" type="#_x0000_t75" style="width:450.75pt;height:200pt">
<v:imagedata src="${"wordml://03000001.jpg"}" />
</v:shape>
</w:pict>

List填充数据表格：

在这里表头没有加入太长了，只是从第二行开始生成数据！

<#list RNCList as RNCList>
                    <w:tr wsp:rsidR="003A2EA1" wsp:rsidRPr="006F59E7" wsp:rsidTr="006F59E7">
