通过freemarker出word的技术解决方案
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
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:
标识是一个表格的标签
表格行:
表格中的单元格：
循环输出数据的方式
<#list problemInfoInterview as problemInfo>
w:hAnsi="Times New Roman" w:hint="eastAsia" />
这里面的行删除

另外，往文档中插入图片的时候，在做模板的时候要往模板中插入一个图片，然后打开文档，然后替换掉base64转码的图片部分。
将图片资源变成base64加密后的图片的代码
将图片转成base64串的方式：
public static String getImageString(String fileName) throws IOException { InputStream in = null; byte[] data = null; try { in = new FileInputStream(fileName); data = new byte[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) : ""; } |
下面是出word用的相关的类：
