本篇博文将和大家一起使用Spring Boot 2.0 和FreeMarker 模板引擎整合实战。
1. 创建新的项目
2. 填写项目配置信息
3. 勾选web 模块
4. 勾选freemarker模板引擎模块
5.填写项目名称和项目保存路径
6. 修改POM文件,添加Freemarker 项目依赖

7. 配置applicaiton.properties
# 设定ftl文件路径
spring.freemarker.template-loader-path=classpath:/templates
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=false
spring.freemarker.expose-session-attributes=false
spring.freemarker.request-context-attribute=request
spring.freemarker.suffix=.ftl
Tips: 其实我试了下，把.ftl 换成.jsp ，创建JSP 文件也是可以的。
8. 创建文件夹和ftl格式文件
index.ftl
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
this is index page
</body>
</html>
welcome.ftl
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
this is welcome page
</body>
</html>
9. 创建 Controller
package com.xingyun.springbootwithfreemarkersample.controller; import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController; @Controller
public class HomeController { @RequestMapping(value = "/")
public String index(){
return "views/index";
} @RequestMapping(value = "/welcome") public String home(){
return "views/welcome";
}
}
Tips: 由于要返回模板页面文件，所以我们只能使用@Controller 而不可以使用@RestController
