通过freemarker制作word比较简单
步骤:制作word模板。制作方式是:将模板word保存成为xml----在xml的word模板中添加相应的标记----将xml的word文件的后缀名改成ftl文件(要注意的是生成xml格式要是2003格式的xml,也就是说拿到的word模板得是2003格式的,否则用wps打开word将会出现问题)
详细步骤如下:
模板制作(将要动态显示的数据打上标记,这个标记是freemarker中的EL标记,要注意的是,要控制值为空的情况,下面${(site.wzmc)?default(“”)}标识当网站名称为空的时候显示空值,如果这里如果不做控制,在实际项目中会显示错误!)
另外要注意的是:
一、不要直接在word中替换掉文字的方式添加标记,这种会有问题。
二、不要使用Eclipse对xml文件进行格式化,这种生成word的时候会提示文档有问题。解决这个的问题是通过firstobject对word的xml进行格式化,对xml进行编辑。(使用firstobject打开带有中文文件名的xml文件的时候,会出现问题,建议使用英文word文档名称)
三、firstobject下载地址:http://www.firstobject.com/dn_editor.htm
其中,要想软件能够格式化xml代码,需要进行设置,设置方式是:打开firstobject----Tools-----Preferences------Format-----Tabs
点击Indent,结果xml变成了有格式化的,效果图如下:
常见标签:
行标记:
<w:p w:rsidR="00790C22"w:rsidRPr="00C07F75" w:rsidRDefault="00790C22"w:rsidP="004018B7">
标识是一个表格的标签
<w:tbl></w:tb1>
表格行:
<w:trw:rsidR="00790C22" w:rsidRPr="00C07F75"w:rsidTr="004018B7"></w:tr>
表格中的单元格:
<w:tc></w:tc>
循环输出数据的方式
<#list problemInfoInterview as problemInfo> <w:tbl> <w:tblPr> <w:tblW w:w="0" w:type="auto"/> <w:tblBorders> <w:top w:val="single" w:sz="4" w:space="0" w:color="auto"/> <w:left w:val="single" w:sz="4" w:space="0" w:color="auto"/> <w:bottom w:val="single" w:sz="4" w:space="0" w:color="auto"/> <w:right w:val="single" w:sz="4" w:space="0" w:color="auto"/> <w:insideH w:val="single" w:sz="4" w:space="0" w:color="auto"/> <w:insideV w:val="single" w:sz="4" w:space="0" w:color="auto"/> </w:tblBorders> <w:tblLook w:val="04A0" w:firstRow="1" w:lastRow="0" w:firstColumn="1" w:lastColumn="0" w:noHBand="0" w:noVBand="1"/> </w:tblPr> <w:tblGrid> <w:gridCol w:w="2235"/> <w:gridCol w:w="6287"/> </w:tblGrid> <w:tr w:rsidR="00790C22" w:rsidRPr="00C07F75" w:rsidTr="004018B7"> <w:tc> <w:tcPr> <w:tcW w:w="2235" w:type="dxa"/> <w:shd w:val="clear" w:color="auto" w:fill="auto"/> <w:vAlign w:val="center"/> </w:tcPr> <w:p w:rsidR="00790C22" w:rsidRPr="00C07F75" w:rsidRDefault="00790C22" w:rsidP="004018B7"> <w:pPr> <w:jc w:val="center"/> <w:rPr> <w:rFonts w:ascii="Times New Roman" w:eastAsia="黑体" w:hAnsi="Times New Roman"/> <w:sz w:val="24"/> <w:szCs w:val="24"/> </w:rPr> </w:pPr> <w:r> <w:rPr> <w:rFonts w:ascii="Times New Roman" w:eastAsia="黑体" w:hAnsi="Times New Roman" w:hint="eastAsia"/> <w:sz w:val="24"/> <w:szCs w:val="24"/> </w:rPr> <w:t>问题名称</w:t> </w:r> </w:p> </w:tc> <w:tc> <w:tcPr> <w:tcW w:w="6287" w:type="dxa"/> <w:shd w:val="clear" w:color="auto" w:fill="auto"/> <w:vAlign w:val="center"/> </w:tcPr> <w:p w:rsidR="00790C22" w:rsidRPr="00C07F75" w:rsidRDefault="00790C22" w:rsidP="004018B7"> <w:pPr> <w:jc w:val="left"/> <w:rPr> <w:rFonts w:ascii="Times New Roman" w:eastAsia="宋体" w:hAnsi="Times New Roman"/> <w:sz w:val="24"/> <w:szCs w:val="24"/> </w:rPr> </w:pPr> <w:r> <w:rPr> <w:rFonts w:ascii="Times New Roman" w:eastAsia="宋体" w:hAnsi="Times New Roman" w:hint="eastAsia" /> <w:sz w:val="24" /> <w:szCs w:val="24" /> </w:rPr> <w:t>${(problemInfo.problemName)?default("")}</w:t> </w:r> </w:p> </w:tc> </w:tr> 这里面的行删除 </w:tbl> <w:p w:rsidR="007F35A8" w:rsidRPr="007F35A8" w:rsidRDefault="007F35A8" w:rsidP="007F35A8" /> -4-5下午6:02:11 *@version V1.0 */ publicclass FreeMarkerUtil { privatestatic Configurationconfiguration =null; privatestatic Map<String, Template>allTemplates =null; static { configuration =new Configuration(); configuration.setDefaultEncoding("utf-8"); //configuration.setClassForTemplateLoading(FreeMarkerUtil.class, // "../template"); try { configuration.setDirectoryForTemplateLoading( new File(TemplateUtil.reportTemplatePath)); }catch (IOException e1) { e1.printStackTrace(); } allTemplates =new HashMap<String, Template>(); try { allTemplates.put("word",configuration.getTemplate(TemplateUtil.templateFileName)); }catch (Exception e) { e.printStackTrace(); thrownew RuntimeException(e); } } public FreeMarkerUtil() { } publicstatic File createDoc(Map<?, ?> dataMap,String type){ String name ="temp" + (int) (Math.random() * 100000) +".doc"; File f =new File(name); Template t =allTemplates.get(type); try { //这个地方不能使用FileWriter因为需要指定编码类型否则生成的Word //文档会因为有无法识别的编码而无法打开 Writer w =new OutputStreamWriter(new FileOutputStream(f),"utf-8"); t.process(dataMap, w); w.close(); }catch (Exception ex) { ex.printStackTrace(); thrownew RuntimeException(); } return f; } publicstatic String getImageString(String fileName)throws IOException { InputStream in =null; byte[] data =null; try { in =new FileInputStream(fileName); data =newbyte[in.available()]; in.read(data); in.close(); }catch (Exception e) { e.printStackTrace(); }finally { if (in !=null){ in.close(); } } Base64Encoder encoder =new Base64Encoder(); return data !=null ? encoder.encode(data) :""; } } |

Ftl语法:
一、判断list的channelUpdateResults是否为空,判断list的大小是否大于某个值,注意加括号 |
<#if channelUpdateResults??> <#if (channelUpdateResults?size>=10) > 未更新数量为“单项否决”。 </#if> </#if> |
二、list迭代 |
<#list queryMainPageScanFailList as mainPageScanFail> </#list> |
四、迭代的时候输出序号 |
${( mainPageScanFail _index+1)?default("")} 其中 |
五、if语句中取数组的值 |
<#if deadUrl[0] == 1> 是 <#else> 否 </#if> |
六、<#assign>赋值,并且通过x_has_next来辨别当前项是否是序列的最后一项的布尔值。 |
<#assign seq = ["winter", "spring", "summer", "autumn"]> <#list seq as x> ${x_index+ 1}. ${x}<#ifx_has_next>,</#if> </#list> |
七、解决出word中因为特殊字符“&”出现的问题,同时判断字符串为NULL和“”空字符串。如果在链接地址中出现了&字符,在生成的word会报错,解决办法是将这个特殊字符用“&”替换掉,示例加链接的代码如下:
<#if (channelUpdate.url)??> <w:hlink w:dest="${(channelUpdate.url)?replace('&','&')}"> <w:r wsp:rsidR="002F59FF" wsp:rsidRPr="002F59FF"> <w:rPr> <w:rStyle w:val="ab"/> <w:rFonts w:ascii="仿宋" w:fareast="仿宋" w:h-ansi="仿宋"/> <wx:font wx:val="仿宋"/> <w:sz w:val="24"/> <w:sz-cs w:val="30"/> </w:rPr> <w:t>${(channelUpdate.url)?replace('&','&')}</w:t> </w:r> </w:hlink> </#if> |
八、多次替换以及replace多次:
${(problemInfo.problemUrl)?replace("&","&")?replace("<","<")?replace(">",">")}
