springboot获取freemarker模版内容

添加依赖

在项目的pom.xml文件中添加

1 <dependency>
2   <groupId>org.freemarker</groupId>
3   <artifactId>freemarker</artifactId>
4   <version>${freemarker.version}</version>
5 </dependency>

或者

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-freemarker</artifactId>
  <version${freemarker.version}</version>
</dependency>

如果没有特殊要求建议添加第一个依赖。后面的依赖项是一个整合依赖，包含了前面依赖项。平常的开发中使用第一个足以满足

工具类

 1 package org.tang.stock.common.utils;
 2 
 3 import freemarker.template.Configuration;
 4 import freemarker.template.Template;
 5 import freemarker.template.TemplateException;
 6 import freemarker.template.TemplateExceptionHandler;

25      * @return String
26      * @throws IOException
27      */
28     public static String parseTemplate(String path,String filename,Object data) throws IOException {
29         Configuration configuration = new Configuration(Configuration.getVersion());
30         configuration.setDefaultEncoding("UTF-8");
31         configuration.setClassForTemplateLoading(FreeMarkerUtil.class,path);
32         configuration.setTemplateExceptionHandler(TemplateExceptionHandler.RETHROW_HANDLER);
33         configuration.setWhitespaceStripping(true);
34         Template template = configuration.getTemplate(filename);
35         // 接收处理后的模版内容
36         StringWriter stringWriter = new StringWriter();
37         try{
38             template.process(data,stringWriter);
39             return stringWriter.toString();
40         }catch (TemplateException e){
41             e.printStackTrace();
42         }finally {
43             stringWriter.close();
44         }
45         return "";
46     }
47 }

ftl模版

 1 <!doctype html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <meta name="viewport"
 6           content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
 7     <meta http-equiv="X-UA-Compatible" content="ie=edge">
 8     <title>Document</title>
 9 </head>
10 <body>
11 
12 <h1>spring boot stock</h1>
13 <span>name </span><span> ${name} </span>
14 <span>desc </span><span> ${desc} </span>
15 </body>
16 </html>

编写测试

 1 import org.junit.jupiter.api.Test;
 2 import org.tang.stock.common.utils.FreeMarkerUtil;
 3 
 4 import java.io.IOException;
 5 import java.util.HashMap;
 6 import java.util.Map;
 7 
 8 
 9 class HtmlFreeMarkerServiceImplTest {
10 
11     String path;
12     String filename;
13     {
14         path = "/freemarker/html/";
15         filename = "index.ftl";
16     }
17     @Test
18     void fetchHtml() throws IOException {
19         Map<String,String> data = new HashMap<>();
20         data.put("name","jack");
21         data.put("desc","xxx");
22 
23         String template = FreeMarkerUtil.parseTemplate(path, filename, data);
24         System.out.println(template);
25     }
26 }
