SpringMVC中使用FreeMarker生成Word文档
FreeMarker简介：
FreeMarker是一款模板引擎：即一种基于模板和要改变的数据，并用来生成输出文本（HTML网页、电子邮件、配置文件、源代码等）的通用工具，它不是面向最终用户的，而是一个Java类库，是一款程序员可以嵌入他们所开发产品的组件。
FreeMarker是免费的，基于Apache许可证2.0版本发布。其模板编写为FreeMarker Template Language（FTL），数据简单、专用的语言。需要准备数据在真实编程语言中来显示，比如数据库查询和业务运算，之后模板显示已经准备好的数据。在模板中，主要用于如何展示数据，而在模板之外注意于要展示什么数据。
SpringMVC是啥在这就不介绍了。
这实例主要是完成使用FreeMarker在SpringMVC框架中生成word文档下载。
1、实例是maven工程，工程对jar包的依赖，pom.xml中主要的依赖是对springMVC和freemarker的包依赖：

2、SringMV配置
applicationContext.xml的配置，这里没有其他复杂的配置，jdbc等，主要为测试FreeMarker的整合：
<!-- 配置自动扫描的包 -->
<context:component-scan base-package="com.zhihua.controller.*"/>
<context:annotation-config/>

接下来是SpringMVC整合FreeMarker最主要的配置了，spring-mvc.xml：
<?xml version="1.0" encoding="UTF-8"?>

3、maven工程的目录，其中com.zhihua.templates包中存放的模板文件，例如本实例中的resume.ftl文件：
4、我们所需要的模板.ftl文件是从哪里来的呢？（本例中的resume.ftl）其中很简单，FreeMarker是模板引擎，所以我们首先要一个模板，生成word文档当然也不例外，我们先新建一个word文件，然后把需要的改变的数据用类似${xxxx}形式当做占位符。
把该word文档另存为XML文件：
另存后建议用用Editplus、Notepad++、Sublime等工具打开查看一下，因为有的时候你写的占位符可能会被拆开（可能会出现类似为${xxxx, xxxxx.... .}</code>形式的拆分，要修改成<code>${}形式），用文件工具打开后，可能回出现未格式化的情况
建议使用工具格式化一下，也方便我们之后修改那些占位符被拆开的问题，不然我们一个个查找是很繁琐的一件事（个人使用Notepad++ XML格式化插件，这个百度一下有插件安装方式）。
5、好了，前期的准备工作都完成了，现在开始功能的实现了。
工具类代码：
package com.zhihua.util;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.HashMap;
import java.util.Map;
import freemarker.template.Configuration;
import freemarker.template.Template;
public class Resume_Word {
private static Configuration configuration = null;
private static Map<String,Template> allTemplate = null;
static{
configuration = new Configuration(Configuration.VERSION_2_3_0);
configuration.setDefaultEncoding("UTF-8");
configuration.setClassForTemplateLoading(Resume_Word.class, "/com/zhihua/templates");
// try {
// configuration.setDirectoryForTemplateLoading(new File("E:\\"));
// } catch (IOException e1) {
// e1.printStackTrace();
// }
allTemplate = new HashMap<String,Template>();
try{
allTemplate.put("test", configuration.getTemplate("resume.ftl"));
}catch(IOException e){
e.printStackTrace();
throw new RuntimeException(e);
}
}
private Resume_Word(){
}
public static File createDoc(Map<?,?> dataMap,String type){
String name = "temp"+(int)(Math.random()*100000)+".doc";
File f = new File(name);
Template t = allTemplate.get(type);
try{
//这个地方不能使用FileWriter因为需要指定编码类型否则声场的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 e){
e.printStackTrace();
throw new RuntimeException(e);
}
return f;
}
}

因为resume.ftl文件中的内容太多了，为了避免篇幅过大，这里就不贴出来了，如果按照前面的步骤，获得resume.ftl不难的。
6、代码部分都准备好了， 接下来就是演示部分
将该工程发布到tomcat中，运行
填写好全部信息（说一下我碰到的问题，我发现如果.ftl文件中的所有占位符如果没有全部填充数据的话，freemarker不能解析出来我们的想要的结果，后台会报错，改占位符的为值为null或者是miss，这是不允许的！）
打开下载的word文件，和原本word文档进行比较一下
自此本实例结束！

FreeMarker简介：
FreeMarker是一款模板引擎：即一种基于模板和要改变的数据，并用来生成输出文本（HTML网页、电子邮件、配置文件、源代码等）的通用工具，它不是面向最终用户的，而是一个Java类库，是一款程序员可以嵌入他们所开发产品的组件。
FreeMarker是免费的，基于Apache许可证2.0版本发布。其模板编写为FreeMarker Template Language（FTL），数据简单、专用的语言。需要准备数据在真实编程语言中来显示，比如数据库查询和业务运算，之后模板显示已经准备好的数据。在模板中，主要用于如何展示数据，而在模板之外注意于要展示什么数据。
SpringMVC是啥在这就不介绍了。
这实例主要是完成使用FreeMarker在SpringMVC框架中生成word文档下载。
1、实例是maven工程，工程对jar包的依赖，pom.xml中主要的依赖是对springMVC和freemarker的包依赖：

2、SringMV配置
applicationContext.xml的配置，这里没有其他复杂的配置，jdbc等，主要为测试FreeMarker的整合：
<!-- 配置自动扫描的包 -->
<context:component-scan base-package="com.zhihua.controller.*"/>
<context:annotation-config/>

接下来是SpringMVC整合FreeMarker最主要的配置了，spring-mvc.xml：
<?xml version="1.0" encoding="UTF-8"?>

3、maven工程的目录，其中com.zhihua.templates包中存放的模板文件，例如本实例中的resume.ftl文件：
4、我们所需要的模板.ftl文件是从哪里来的呢？（本例中的resume.ftl）其中很简单，FreeMarker是模板引擎，所以我们首先要一个模板，生成word文档当然也不例外，我们先新建一个word文件，然后把需要的改变的数据用类似${xxxx}形式当做占位符。
把该word文档另存为XML文件：
另存后建议用用Editplus、Notepad++、Sublime等工具打开查看一下，因为有的时候你写的占位符可能会被拆开（可能会出现类似为${xxxx, xxxxx.... .}</code>形式的拆分，要修改成<code>${}形式），用文件工具打开后，可能回出现未格式化的情况
建议使用工具格式化一下，也方便我们之后修改那些占位符被拆开的问题，不然我们一个个查找是很繁琐的一件事（个人使用Notepad++ XML格式化插件，这个百度一下有插件安装方式）。
5、好了，前期的准备工作都完成了，现在开始功能的实现了。
工具类代码：
package com.zhihua.util;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.HashMap;
import java.util.Map;
import freemarker.template.Configuration;
import freemarker.template.Template;
public class Resume_Word {
private static Configuration configuration = null;
private static Map<String,Template> allTemplate = null;
static{
configuration = new Configuration(Configuration.VERSION_2_3_0);
configuration.setDefaultEncoding("UTF-8");
configuration.setClassForTemplateLoading(Resume_Word.class, "/com/zhihua/templates");
// try {
// configuration.setDirectoryForTemplateLoading(new File("E:\\"));
// } catch (IOException e1) {
// e1.printStackTrace();
// }
allTemplate = new HashMap<String,Template>();
try{
allTemplate.put("test", configuration.getTemplate("resume.ftl"));
}catch(IOException e){
e.printStackTrace();
throw new RuntimeException(e);
}
}
private Resume_Word(){
}
public static File createDoc(Map<?,?> dataMap,String type){
String name = "temp"+(int)(Math.random()*100000)+".doc";
File f = new File(name);
Template t = allTemplate.get(type);
try{
//这个地方不能使用FileWriter因为需要指定编码类型否则声场的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 e){
e.printStackTrace();
throw new RuntimeException(e);
}
return f;
}
}

因为resume.ftl文件中的内容太多了，为了避免篇幅过大，这里就不贴出来了，如果按照前面的步骤，获得resume.ftl不难的。
6、代码部分都准备好了， 接下来就是演示部分
将该工程发布到tomcat中，运行
填写好全部信息（说一下我碰到的问题，我发现如果.ftl文件中的所有占位符如果没有全部填充数据的话，freemarker不能解析出来我们的想要的结果，后台会报错，改占位符的为值为null或者是miss，这是不允许的！）
打开下载的word文件，和原本word文档进行比较一下
自此本实例结束！
