Spring boot之使用freemarker

大纲

（1）在pom.xml中引入freemarker;

（2）如何关闭freemarker缓存

（3）编写模板文件.ftl

（4）编写访问文件的controller

在pom.xml中引入freemarker

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>

如何关闭freemarker缓存

########################################################
###FREEMARKER (FreeMarkerAutoConfiguration)
########################################################
spring.freemarker.allow-request-override=false
spring.freemarker.cache=true
spring.freemarker.check-template-location=true
spring.freemarker.charset=UTF-8
spring.freemarker.content-type=text/html
spring.freemarker.expose-request-attributes=false
spring.freemarker.expose-session-attributes=false
spring.freemarker.expose-spring-macro-helpers=false

#spring.freemarker.suffix=.ftl
#spring.freemarker.template-loader-path=classpath:/templates/ #comma-separated list
#spring.freemarker.view-names= # whitelist of view names that can be resolved

编写模板文件.ftl

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head>
<title>Hello World!</title>
</head>
<body>
<h1>Hello.v.2</h1>
<p>${hello}</p>
</body>
</html>

编写访问文件的controller

@RequestMapping("/helloFtl")
public String helloFtl(Map<String,Object> map){
map.put("hello","from TemplateController.helloFtl");
return "/helloFtl";
}

代码如下：

Controller类

package com.kfit;

import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * 注意：
 * 1.在Thymeleaf 模板文件中，标签是需要闭合的，3.0之前是需要闭合的
 * 2. thymeleaf 3.0+ 是可以不强制要求闭合的。
 * 
 * 3. 支持同时使用多个模板引擎，比如：thymeleaf和freemarker 可以并存。
 * 
 
 */
@Controller
@RequestMapping("/templates")
public class TemplatesController {
    
    /**
     * 映射地址是：/templates/hello
     * @return
     */
    @RequestMapping("/hello")
    public String hello(Map<String,Object> map){
        //返回的是ModelAndView对象;
//        ModelAndView mv = new ModelAndView("hello");
//        return mv;
        map.put("name","Andy");
        return "hello";
    }
    
    @RequestMapping("/helloFtl")
    public String helloFtl(Map<String,Object> map){
        map.put("name","Andy");
        return "helloFtl";
    }
    
}

模板

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Insert title here</title>
</head>
<body>
    hello ${name}
        
</body>
</html>
