本文介绍如何使用Spring Boot结合Thymeleaf模板引擎进行Web开发，涵盖项目搭建、依赖配置及基本控制器实现。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

Spring boot开发web项目，通常打成jar包，使用内置的web服务器 Tomcat、Jetty、undertow 来运行。静态资源（css、js、图片等）默认放在resources/static下面。如果要修改默认存放目录，可以通过设置属性 spring.mvc.static-path-pattern来实现。

模板文件默认放在 templates目录下。Spring boot支持使用模板来开发web应用，支持的模板类型包括：

FreeMarker
Groovy
Thymeleaf
Mustache

Spring boot不建议使用jsp开发web。本文使用Thymeleaf来作为模板引擎开发web项目。

Thymeleaf

Thymeleaf是一个Java模板引擎开发库，可以处理和生成HTML、XML、JavaScript、CSS和文本，在Web和非Web环境下都可以正常工作。Thymeleaf可以跟Spring boot很好的集成。

项目结构

几个重要文件整理如下：

JsoupApplication.java

package com.example.jsoup;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;


@SpringBootApplication
@EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class)
@ComponentScan(basePackages= {"com.example.jsoup.*"})
public class JsoupApplication extends SpringBootServletInitializer{

	public static Logger logger = LoggerFactory.getLogger(JsoupApplication.class);
	
	
	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		logger.info("《使用外部tomcat配置启动springboot》");
		application.sources(this.getClass());
		return super.configure(application);
	}
	
	public static void main(String[] args) {
		
		SpringApplication.run(JsoupApplication.class, args);
		logger.info("*****************");
		logger.info("与Jsoup整合springboot_thymeleaf启动完成!!");
		logger.info("*****************");
	}
}
