参考Beetl官网：http://ibeetl.com/guide/#beetl_4_6

添加maven依赖

<dependency>
    <groupId>com.ibeetl</groupId>
    <artifactId>beetl-framework-starter</artifactId>
    <version>1.1.22.RELEASE</version>
</dependency>

配置beetl

通过java config来配置 beetl需要的BeetlGroupUtilConfiguration，和 BeetlSpringViewResolver，参考代码如下：

@Configuration
public class BeetlConf {
    @Value("templates") 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);
        beetlSpringViewResolver.setSuffix(".html");      //设置后缀后即可在controller中使用 return "/hello" 而不必 return "hello.html"
        return beetlSpringViewResolver;
    }


}

将其中

@Value("${beetl.templatesPath}") String templatesPath;//模板跟目录 ，比如 "templates"

替换为自己项目下的templates目录

注意：可以通过Application.properties 配置如下属性禁用Beetl
beetl.enabled=false
