开门见山：应用到的技术有spring-boot,mybatis,springmvc,mysql,thymeleaf。
首先给自己的eclipse安装sts，传送门：https://blog.csdn.net/zhen_6137/article/details/79383941
1.创建spring-boot项目
new project找到Spring Starter Project
点击next之后 填写参数
下图可选择依赖，可以跳过
2.创建必要文件及文件夹
finish之后可以看到我们创建的项目，在src/main/resources源代码文件夹上右键，选择new->folder。新建以下几个文件夹，static（用于存放静态资源，如js、css或img）和templates（用于存放html）。
添加依赖，pom.xml文件：

配置文件为：
server:
port: 8080
servlet:
context-path: /boot
# =====================数据源配置===========================
spring:
datasource:
url: jdbc:mysql://127.0.0.1:3306/boottest?characterEncoding=utf8
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
# =====================Thymeleaf 配置===========================
thymeleaf:
enabled: true # 是否启用thymeleaf模板解析
cache: false # 是否开启模板缓存（建议：开发环境下设置为false，生产环境设置为true）
check-template-location: true # Check that the templates location exists.
servlet:
content-type: text/html # 模板的媒体类型设置，默认为text/html
encoding: UTF-8 # 模板的编码设置，默认UTF-8
characterEncoding: UTF-8
#view-names: # 设置可以被解析的视图，以逗号,分隔
#excluded-view-names: # 排除不需要被解析视图，以逗号,分隔
#mode:HTML5 # 模板模式设置，默认为HTML5
prefix: classpath:/templates/ # 前缀设置，SpringBoot默认模板放置在classpath:/template/目录下
suffix: .html # 后缀设置，默认为.html
#template-resolver-order: # 模板在模板链中被解析的顺序
jmx:
# enabled: false
default-domain: springboottest
logging:
path: D:\JavaFiles\logs\spring boot\logs
level:
com.springboottest.dao: DEBUG图示：
3.测试项目是否可运行
接下来创建controller和html测试项目是否可运行：
图示：
IndexController.java代码：
package com.springboottest.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/")
public class IndexController {
@RequestMapping("/")
public String indexPage(){
return "index";
}
}
index.html代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>welcome to spring-boot</h1>
</body>
</html>由于我们安装了sts插件，eclipse可以很方便的启动项目，如图示操作即可：
待启动完毕之后，在浏览器输入http://localhost:8080/boot/地址之后效果：
至此eclipse搭建springboot项目完毕。
在下篇博客将使用thymeleaf、bootstrap实现注册登录。《Spring-boot使用eclipse搭建项目（二）》
