freemarker是一种web应用组件,类似thymeleaf模板引擎。
1 要利用freemarker生成word文档,首先需要创建word文档模板(即.doc文档),需要用户填写的值可以使用${string}代替,但是在后台给Model赋值的时候要名称对应,然后将后缀名改为.ftl。将如模板名称为model.ftl
2 再将model.ftl放置在springboot项目的resource目录下
3 导入freemarker依赖的jar包
org.springframework.boot
spring-boot-starter-freemarker
org.freemarker
freemarker
2.3.22
4 配置文件
spring.freemarker.template-loader-path=/
#关闭缓存即时刷新,生产环境需要改成true;
spring.freemarker.cache=false
spring.freemarker.charset=utf-8
spring.freemarker.check-template-location=true
spring.freemarker.content-type=text/html
spring.freemarker.expose-request-attributes=true
spring.freemarker.expose-session-attributes=true
spring.freemarker.request-context-attribute=request
5 页面访问控制
@RequestMapping("/tomodel.action")
public String freemarker(Model model){
Map map=new HashMap();
map.put("name","张三");
model.addAttribute("name","张三1");
model.addAttribute("sex","男"); model.addAttribute("age","20"); model.addAttribute("xueli","本科"); model.addAttribute("live","湖南.衡阳"); model.addAttribute("hukou","湖南.郴州"); model.addAttribute("tel","15570960031");
model.addAttribute("email","[email protected]"); model.addAttribute("where","广州"); model.addAttribute("gongzi","20000"); model.addAttribute("zhuangtai","找工作"); model.addAttribute("xingzhi","全职"); model.addAttribute("hangye","it行业");
model.addAttribute("pingjia","积极向上,动手能力强,善于解决问题。");
return "model";
}
6 界面(乱码了,统一了编码格式还是乱码,再找找)
7 下载生成word文档(这里没有下载图片,图片存在于服务器,所以只要根据url下载图片到本地文件夹再引入就可以了)
7 .1 生成word的方法:
/**
* 生成word文件
* @param dataMap word中需要展示的动态数据,用map集合来保存
* @param templateName word模板名称,例如:model.ftl
* @param filePath 文件生成的目标路径,例如:D:\\freemarker
* @param fileName 生成的文件名称,例如:Test.doc
*/ public static void createWord(Map dataMap,String templateName,String filePath,String fileName){
try {
//创建配置实例
Configuration configuration = new Configuration();
//设置编码
configuration.setDefaultEncoding("utf-8");
//ftl模板文件
configuration.setClassForTemplateLoading(FreemarkerUtil.class,"/");
//获取模板
Template template = configuration.getTemplate(templateName);
//输出文件
File outFile = new File(filePath+File.separator+fileName);
//如果输出目标文件夹不存在,则创建
if (!outFile.getParentFile().exists()){
outFile.getParentFile().mkdirs();
}
//将模板和数据模型合并生成文件
Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile),"utf-8"));
//生成文件
template.process(dataMap, out);
//关闭流
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
7.2 下载请求:
@RequestMapping("/model.action")
public void model(){
Map dataMap=new HashMap();
dataMap.put("name","张三");
dataMap.put("sex","男"); dataMap.put("age","20");dataMap.put("xueli","本科"); dataMap.put("live","湖南.衡阳"); dataMap.put("hukou","湖南.郴州");dataMap.put("tel","15570960031");
dataMap.put("email","[email protected]"); dataMap.put("where","广州"); dataMap.put("gongzi","20000"); dataMap.put("zhuangtai","找工作"); dataMap.put("xingzhi","全职"); dataMap.put("hangye","it行业");dataMap.put("zhiye","it行业");
dataMap.put("pingjia","积极向上,动手能力强,善于解决问题。");
String templateName="model.ftl";
String filePath="D:\\freemarker";
String fileName="Test.doc";
try {
FreemarkerUtil.createWord(dataMap,templateName,filePath,fileName);
} catch (Exception e) {
e.printStackTrace();
System.out.println("文件下载失败");
}
}
8 左后在D:\\freemarker下生成了Test.doc文档(还是有乱码,再找找)。
