Freemarker静态化Demo(两种方式)

Freemarker

Demo

使用单元测试，集成springboot开发

1. 在test下创建resources目录，在固定文件夹(template)在创建模板文件
   

2. 添加依赖

   <dependencies>
       <dependency>
           <groupId>org.springframework.bootgroupId>
           <artifactId>spring-boot-starter-freemarkerartifactId>
       dependency>
       <dependency>
           <groupId>org.projectlombokgroupId>
           <artifactId>lombokartifactId>
       dependency>
       <dependency>
           <groupId>com.squareup.okhttp3groupId>
           <artifactId>okhttpartifactId>
       dependency>
       <dependency>
           <groupId>commons-iogroupId>
           <artifactId>commons-ioartifactId>
       dependency>
       <dependency>
           <groupId>org.springframework.bootgroupId>
           <artifactId>spring-boot-starter-testartifactId>
       dependency>
       <dependency>
           <groupId>org.springframework.bootgroupId>
           <artifactId>spring-boot-starter-webartifactId>
       dependency>
   dependencies>
   

3. 编写操作类

   /**
    * 模板测试类
    */
   @SpringBootTest
   @RunWith(SpringRunner.class)
   public class FreemarkerTest {
   
       /**
        * 根据模板文件生成html文件
        */
       @Test
       public void getHtmlByFile() throws IOException, TemplateException {
           //创建配置类
           Configuration configuration = new Configuration(Configuration.getVersion());
           //设置模板路径
           String path = this.getClass().getResource("/").getPath();
           configuration.setDirectoryForTemplateLoading(new File(path+"/templates/"));
           //加载模板
           Template template = configuration.getTemplate("test1.ftl");
           //数据模型
           Map<String,Object> map = new HashMap<>();
           map.put("name","黑马程序员");
           //静态化
           String templateString = FreeMarkerTemplateUtils.processTemplateIntoString(template, map);
           //输出文件到指定目录
           //System.out.println(templateString);
           InputStream is = IOUtils.toInputStream(templateString);
           FileOutputStream os = new FileOutputStream(new File("f:/test1.html"));
           IOUtils.copy(is, os);
           os.close();
           is.close();
       }
   
       /**
        * 根据模板字符串生成html文件
        */
       @Test
       public void getHtmlByString() throws IOException, TemplateException {
           //创建配置类
           Configuration configuration = new Configuration(Configuration.getVersion());
           //设置模板字符串
           String  templateString=""  +
               "\n"  +
               "        \n"  +
               "        \n"  +
               "        名称：${name}\n"  +
               "        \n"  +
               "";
           //模板加载器获取模板
           StringTemplateLoader loader = new StringTemplateLoader();
           loader.putTemplate("template",templateString);
           configuration.setTemplateLoader(loader);
           //获取模板
           Template template = configuration.getTemplate("template");
           //数据模型
           Map<String,Object> map = new HashMap<>();
           map.put("name","黑马程序员");
           //静态化
           String content = FreeMarkerTemplateUtils.processTemplateIntoString(template, map);
           //输出文件到指定目录
           //System.out.println(content);
           InputStream is = IOUtils.toInputStream(content);
           FileOutputStream os = new FileOutputStream(new File("f:/test1.html"));
           IOUtils.copy(is, os);
           os.close();
           is.close();
       }
   }
