Spring boo + thymeleaf 生成静态html文件，实现小程序嵌套模板

1.引入依赖

Maven方式

 
        org.thymeleaf
         thymeleaf
         3.0.7.RELEASE
     

Grade方式

compile("org.thymeleaf:thymeleaf:3.0.7.RELEASE")

2.引入两个工具类

ApplicationContextHolder

package com.taoweilai.common.utils;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextHolder implements ApplicationContextAware {
	
	private static ApplicationContext applicationContext;
	@Override
	public void setApplicationContext(ApplicationContext ctx) throws BeansException {
		applicationContext = ctx;
	}
	public static ApplicationContext getApplicationContext() {
		return applicationContext;
	}
	
	public static  T getBean(Class clazz){
		return applicationContext.getBean(clazz);
	}

	@SuppressWarnings("unchecked")
	public static  T getBean(String name){
		return (T) applicationContext.getBean(name);
	}
}

TemplateUtils

package com.taoweilai.common.utils;

import java.io.FileWriter;
import java.io.IOException;

import org.springframework.beans.factory.annotation.Autowired;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;

public class TemplateUtils {
	
	@Autowired
	public static final TemplateEngine engine = ApplicationContextHolder.getBean(TemplateEngine.class);
	/**
	 * 生成静态文件
	 * @param freeTempName 模板名称
	 * @param context 数据内容
	 * @param outFilePath 输出路径
	 * @return
	 */
	public static boolean process(String freeTempName,Context context,String outFilePath) {
		FileWriter fileWriter = null;
		try {
			fileWriter = new FileWriter(outFilePath);
			engine.process(freeTempName, context,fileWriter);
		} catch (IOException e) {
			e.printStackTrace();
			return false;
		} finally {
			try {
				fileWriter.close();
			} catch (IOException e) {
				e.printStackTrace();
				return false;
			}
		}
		return true;
	}
}

3.创建模板

templates/example.html

4.在单元测试里面测试

在D中创建test目录

@Test
public void testTemplate() {
	String url = "D:/test/";
	Context context = new Context();
	context.setVariable("name", "world");
	TemplateUtils.process("template.html", context, url+"test.html");
}

右击Juint Test运行后

在文件夹中查看已有文件生成

开发页面

生成成功

小程序中使用web-view标签可以嵌套html
