> 省略创建springboot项目的步骤

配置pox.xml添加freemarker依赖

<dependency>
    			<groupId>com.ibeetl</groupId>
    			<artifactId>beetl-framework-starter</artifactId>
    			<version>1.1.70.RELEASE</version>
    		</dependency>

**法一：**

starter 自动处理以btl结尾的视图，模板根目录是Spring Boot默认的templates目录。

这样看来可以直接使用

创建beetl页面userInfo.btl ![20181226171651680.png][]当然也可用直接用html，以btl为后缀是为了区分其他模板语言，也为了让启动以来直接处理。

<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    ${name}
    ${id}
    </body>
    </html>

编写BeetlController

@Controller
    @RequestMapping("beetl")
    public class BeetlController {
    
        @RequestMapping("/showuser.html")
        public ModelAndView showUsername(String id) {
            ModelAndView mv = new ModelAndView();
            mv.addObject("id", id);
            mv.addObject("name", "dongguo1");
            mv.setViewName("/userInfo.btl");
            return mv;
        }
    }

application.yml中的配置

server:
        port: 8080
        servlet:
          context-path: /springboot-web

** 法二(转** [https://blog.csdn.net/xslde\_com/article/details/81132673][https_blog.csdn.net_xslde_com_article_details_81132673]**)：**

使用Starter来配置已经够用，如果你想自己配置模板引擎， 通过java config来配置 beetl需要的BeetlGroupUtilConfiguration，和 BeetlSpringViewResolver，

创建beetl配置文件：BeetlConf.class

package com.xslde.configurer;
     
    import org.beetl.core.resource.ClasspathResourceLoader;
    import org.beetl.ext.spring.BeetlGroupUtilConfiguration;
    import org.beetl.ext.spring.BeetlSpringViewResolver;
    import org.springframework.beans.factory.annotation.Qualifier;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
     
    /**
     * @Author xslde
     * @Description
     * @Date 2018/7/20 15:17
     */
    @Configuration //加载配置文件
    public class BeetlConf {
     
        @Value("${beetl.templatesPath}") String templatesPath;//模板根目录 ，比如 "templates"
        @Bean(name = "beetlConfig")
        public BeetlGroupUtilConfiguration getBeetlGroupUtilConfiguration() {
            BeetlGroupUtilConfiguration beetlGroupUtilConfiguration = new BeetlGroupUtilConfiguration();
            //获取Spring Boot 的ClassLoader
            ClassLoader loader = Thread.currentThread().getContextClassLoader();
            if(loader==null){
                loader = BeetlConf.class.getClassLoader();
            }
            //beetlGroupUtilConfiguration.setConfigProperties(extProperties);//额外的配置，可以覆盖默认配置，一般不需要
            ClasspathResourceLoader cploder = new ClasspathResourceLoader(loader,
                    templatesPath);
            beetlGroupUtilConfiguration.setResourceLoader(cploder);
            beetlGroupUtilConfiguration.init();
            //如果使用了优化编译器，涉及到字节码操作，需要添加ClassLoader
            beetlGroupUtilConfiguration.getGroupTemplate().setClassLoader(loader);
            return beetlGroupUtilConfiguration;
     
        }
     
        @Bean(name = "beetlViewResolver")
        public BeetlSpringViewResolver getBeetlSpringViewResolver(@Qualifier("beetlConfig") BeetlGroupUtilConfiguration beetlGroupUtilConfiguration) {
            BeetlSpringViewResolver beetlSpringViewResolver = new BeetlSpringViewResolver();
            beetlSpringViewResolver.setContentType("text/html;charset=UTF-8");
            beetlSpringViewResolver.setOrder(0);
            beetlSpringViewResolver.setConfig(beetlGroupUtilConfiguration);
            return beetlSpringViewResolver;
        }
     
    }

在application.yml中配置模板引擎路径：

server:
        port: 8080
        servlet:
          context-path: /springboot-web
    #模板路径
    beetl:
      templatesPath: templates

创建一个 BeetlAction.class

package com.xslde.action;
     
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.GetMapping;
     
    /**
     * @Author xslde
     * @Description
     * @Date 2018/7/20 15:22
     */
    @Controller
    public class BeetlAction {
     
        @RequestMapping("/index")
        public String beetl(Model model) {
            model.addAttribute("beetl", "测试一下通过模板引擎传递参数！");
            return "index.html";
        }
     
    }

在templates文件夹下创建一个html文件

index.html

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>测试页面</title>
    </head>
    <body>
    <span>通过beetl取值</span>
    <h1>${beetl!}</h1>
    </body>
    </html>
