spring boot 我们都知道是一个简化配置的服务，省去繁琐的xml配置，以properties和yml还有 注解形式来替代之前的xml配置。

我们首先实现spring boot 对freemarker的支持，引入pom

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

在yml中添加配置项：

spring:     freemarker:         template-loader-path: classpath:/ftl/

classpath后面为前缀。也可以在注解配置类中实现

新建配置类：FreeMarkerConfig.java

import com.jagregory.shiro.freemarker.ShiroTags; import freemarker.template.TemplateException; import freemarker.template.TemplateModelException; import java.io.IOException; import java.util.Properties; import javax.annotation.PostConstruct; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.ui.freemarker.FreeMarkerConfigurationFactory; import org.springframework.web.servlet.ViewResolver; import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer; import org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver; /**  * @author zhuxiaomeng  * @date 2018/1/2.  * @email 154040976@qq.com  */ @Configuration public class FreeMarkerConfig {     @Bean   public ViewResolver viewResolver() {     FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();     resolver.setCache(false);     resolver.setViewClass(org.springframework.web.servlet.view.freemarker.FreeMarkerView.class);     resolver.setRequestContextAttribute("re");     resolver.setExposeSpringMacroHelpers(true);     resolver.setExposeRequestAttributes(true);     resolver.setExposeSessionAttributes(true);     resolver.setSuffix(".ftl");     resolver.setContentType("text/html; charset=UTF-8");     return resolver;   }    @Bean   public FreeMarkerConfigurer freemarkerConfig() throws IOException, TemplateException {     FreeMarkerConfigurationFactory factory = new FreeMarkerConfigurationFactory();     factory.setTemplateLoaderPaths("classpath:/ftl/", "src/main/resources/ftl");     factory.setDefaultEncoding("UTF-8");     FreeMarkerConfigurer result = new FreeMarkerConfigurer();      freemarker.template.Configuration configuration = factory.createConfiguration();     configuration.setClassicCompatible(true);     result.setConfiguration(configuration);     Properties settings = new Properties();     settings.put("template_update_delay", "0");     settings.put("default_encoding", "UTF-8");     settings.put("number_format", "0.##########");     settings.put("datetime_format", "yyyy-MM-dd HH:mm:ss");     settings.put("classic_compatible", true);     settings.put("template_exception_handler", "ignore");     result.setFreemarkerSettings(settings);     return result;   }  }

setRequestContextAttribute：设置属性名称，为freemarker前端 RequestContext 的别名
