springboot加载远程freemarker模板ftl

springboot加载远程freemarker模板ftl

解决方法：

1、springboot启动类继承以下类：

package com.bx.common;

import com.bx.common.conf.MyFreemarkerView;

import freemarker.template.Configuration;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.CommandLineRunner;

import org.springframework.boot.autoconfigure.freemarker.FreeMarkerProperties;

import org.springframework.boot.builder.SpringApplicationBuilder;

import org.springframework.context.annotation.Bean;

import org.springframework.core.env.Environment;

import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;

import org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver;

import java.util.*;

public class BaseApplication {

   @Autowired

   private Environment env;

   @Autowired

   private FreeMarkerProperties fmkProp;

   protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

       return null;

   }

   @Bean

   public FreeMarkerConfigurer freeMarkerConfigurer() {

       FreeMarkerConfigurer factory = new FreeMarkerConfigurer();

       factory.setTemplateLoaderPaths(this.fmkProp.getTemplateLoaderPath());

       factory.setPreferFileSystemAccess(this.fmkProp.isPreferFileSystemAccess());

       factory.setDefaultEncoding(this.fmkProp.getCharsetName());

       Properties settings = new Properties();

       settings.putAll(this.fmkProp.getSettings());

       factory.setFreemarkerSettings(settings);

       Configuration configuration = null;

       try {

           configuration = factory.createConfiguration();

          // configuration.setAutoImports(new HashMap());

           String path=this.env.getProperty("spring.freemarker.template-loader-path");

           //加载远程的ftl文件路径

           configuration.setTemplateLoader(new RemoteTemplateLoader(path));

       } catch (Exception var4) {

           var4.printStackTrace();

       }

       factory.setConfiguration(configuration);

       return factory;

   }

   @Bean

   public CommandLineRunner customFreemarker(final FreeMarkerViewResolver resolver) {

       return new CommandLineRunner() {

           public void run(String... strings) throws Exception {

               resolver.setViewClass(MyFreemarkerView.class);

           }

       };

   }

}

2、MyFreemarkerView类

import org.springframework.web.servlet.view.freemarker.FreeMarkerView;

import javax.servlet.http.HttpServletRequest;

import java.util.Map;

public class MyFreemarkerView extends FreeMarkerView {

   public MyFreemarkerView() {

   }

   protected void exposeHelpers(Map<String, Object> model, HttpServletRequest request) throws

Exception {

       model.put("yml", "全局变量，可以在ftl中使用");

       super.exposeHelpers(model, request);

   }

}

3、application.yml配置

spring:

 freemarker:

   cache: false

   template-loader-path: http://localhost:18080/
