Springboot
1.引入Freemarker jar包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
2.配置application.properties
### freemarker spring.freemarker.templateLoaderPath=classpath:/templates/ spring.freemarker.suffix=.ftl spring.freemarker.charset=UTF-8 spring.freemarker.request-context-attribute=request spring.freemarker.settings.number_format=0.##########
3.創建ftl文件
在resource文件下新增文件夾templates，在templates文件夾下存放ftl文件，例如：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>FreeMarker</title>
</head>
<body>
<h1>Simple project</h1>
<h1>${key}</h1>
</body>
</html>
4.新建controller調用方法
@SuppressWarnings("unchecked")
@RequestMapping(value="/test",method=RequestMethod.GET)
public String test(Model model,HttpServletRequest request) {
model.addAttribute("key","test project");
return "test";
}
5.生成html靜態文件
使用工具類：
@Autowired
private Configuration cfg;
/** * @param modeName 模板名稱 * @param targetFileName 生成后的HTML名稱 * @param params 傳入模板的參數 * @Author: zy * @Date: 2020-6-4 09:39:47 * @Description:生成靜態頁面 */ public void createHtmlByMode(String modeName, String targetFileName, Map<String, Object> params) { Writer out = null; // 找到服務器緩存目錄，可以自己指定目錄 String folder = PropertisUtil.getApplicationProperties("healthReport.logs.urls") + targetFileName; // 通過匹配路徑格式拼接完整生成路徑 String outFile = folder; try { File file = new File(outFile); // 生成空HTML文件 if (!file.exists()) { file.createNewFile(); } // 創建模版對象 Template template = cfg.getTemplate(modeName); // 設置輸出流 out = new OutputStreamWriter(new FileOutputStream(file), "UTF-8");// 設置編碼 UTF-8 // 模版數據插入參數，通過輸出流插入到HTML中 template.process(params, out); } catch (Exception e) { e.printStackTrace(); } finally { if (null != out) { try { out.flush(); out.close(); } catch (IOException e) { e.printStackTrace(); } } } }
修改controller中的方法：
@SuppressWarnings("unchecked")
@RequestMapping(value="/test",method=RequestMethod.GET)
public String test(Model model,HttpServletRequest request) {
model.addAttribute("key","test project");
//生成靜態文件
Map param=new HashMap();
param.put("key", "我是被生成的靜態文件");
createHtmlByMode("test.ftl","test.html",param);
return "test";
}
實現效果（我這里默認保存到d:/testlogs）：
Springmvc（和springboot大致相同，此處只留下配置）
1.引入Freemarker jar包
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.freemarker/freemarker -->
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.25-incubating</version>
</dependency>
2.springmvc配置
<!-- freemarker -->
<bean id="freeMarkerConfigurer"
class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath" value="/freemarker/ftl/"></property>
<property name="defaultEncoding" value="utf-8" />
<property name="freemarkerSettings">
<props>
<prop key="template_update_delay">1</prop>
<prop key="locale">zh_CN</prop>
<prop key="datetime_format">yyyy-MM-dd</prop><!-- 時間格式化 -->
<prop key="date_format">yyyy-MM-dd</prop>
<prop key="number_format">#.##</prop>
</props>
</property>
</bean>
<bean id="freeMarkerViewResolver"
class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
<property name="cache" value="true" />
<property name="prefix" value="" /><!-- 上面已經配了，這里就不用配啦 -->
<property name="suffix" value=".ftl" />
<property name="contentType" value="text/html;charset=UTF-8" />
<property name="allowSessionOverride" value="true" />
<property name="allowRequestOverride" value="true" />
<property name="exposeSpringMacroHelpers" value="true" />
<property name="exposeRequestAttributes" value="true" />
<property name="exposeSessionAttributes" value="true" />
<property name="requestContextAttribute" value="request" />
</bean>
3.調用方式
/**返回模板信息*/ @SuppressWarnings("unchecked") @RequestMapping(value="/test",method={RequestMethod.GET}) public ModelAndView test(HttpServletRequest request) { ModelAndView mv = new ModelAndView(); //設置參數 mv.addObject("key", "測試freemarker"); //配置模板 mv.setViewName("test"); return mv; }
