spring boot+thymeleaf+bootstrap实现后台管理系统界面

最近在学spring boot ，学习一个框架无非也就是使用它来做以前做的事情，两者比较才有不同，说一下自己使用的体会。
先来说下spring boot ，微框架。快速开发，相当于零配置，从一个大神那看来的说：spring boot 相当于框架的框架 ，就是集成了很多，用哪个添加哪个的依赖就行，这样的话自己看不到配置，对于习惯了使用配置刚使用spring boot的开发者来说可能还有点不习惯，什么都不用配，看不到配置感觉对项目整体架构有点陌生，再说在spring boot 中使用 thymeleaf 。就拿个最简单的例子来说明 jsp显示helloworld , thymeleaf显示helloworld，两者也就pom文件引入依赖和属性文件配置不同，在你使用jsp的时候不要引入thymeleaf的依赖，当然在使用thymeleaf的时候也不要引入jsp的依赖 有可能会产生冲突，spring boot 官方是推荐使用thymeleaf 我个人感觉也不错，开始项目吧！

1 、首先 建一个meaven项目 看一下建好的项目整体结构

建好项目结构弄pom.xml ,这个demo只用到thymeleaf，没有数据库方面的依赖，所需依赖很少

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

 <!-- thymeleaf -->

 <plugins>
  <plugin>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-maven-plugin</artifactId>
  </plugin>
 </plugins>
 </build>
</project>

在src /main/resource 建立 application.properties文件

server.port=8080
server.session.timeout=10
server.tomcat.uri-encoding=UTF-8 

spring.thymeleaf.prefix=classpath:/views/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
spring.thymeleaf.cache=false

写入口程序

package com.zanghan.youyu; 

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication; 

@SpringBootApplication
public class YouYuApplication { 

 public static void main(String[] args) {
 SpringApplication.run(YouYuApplication.class, args);
 }
}

控制器跳转bootstrap界面

package com.zanghan.youyu.controller; 

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller
public class LoginController {
 @RequestMapping("/")
 public String index(){
 return "/index";
 }
}

引入bootstrap js css 放在哪里？放在static文件夹里，views中放的是页面

index.html界面存放在 src/main/resource 下的views 文件夹里，为啥不是tepmlates 因为在属性配置文件中写的是views ，thymeleaf 的前缀和后缀都可以改变的

搞定，运行application 输入localhost:8080
