2.创建maven项目

3.填写groupid, artifactid,version.

4.预览project

5.完成创建

6.配置项目，添加一些文件夹。默认是没有src/main/java

File -> Project Structrue -> Modules -> Demo -> 右键创建folder -> mark as Sources

项目结构：

二、创建Spring boot 项目

1. pom.xml内容，dependency

<?xml version="1.0" encoding="UTF-8"?><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">  <modelVersion>4.0.0</modelVersion>  <groupId>com.test</groupId>  <artifactId>Demo</artifactId>  <version>1.0-SNAPSHOT</version>  <parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>1.4.6.RELEASE</version>  </parent>  <dependencies>    <dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-web</artifactId>    </dependency>    <dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-tomcat</artifactId>      <scope>provided</scope>    </dependency>    <dependency>      <groupId>org.apache.tomcat.embed</groupId>      <artifactId>tomcat-embed-jasper</artifactId>    </dependency>  </dependencies>  <properties>    <java.version>1.8</java.version>  </properties>  <build>    <plugins>      <plugin>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-maven-plugin</artifactId>      </plugin>    </plugins>  </build></project>

2. MyApplication.java

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

3. Controller

@Controllerpublic class IndexController {    @RequestMapping("/index")    public String testIndex(){        return "index";    }}

4.在src/main/resources/下创建application.properties

spring.mvc.view.prefix=/WEB-INF/jsp/spring.mvc.view.suffix=.jsp

5.在src/main/webapp/jsp/下创建index.jsp

6.运行MyApplication.java，在网址输入http://localhost:8080/index
