這篇文章主要介紹了使用IDEA創(chuàng)建SpringBoot項(xiàng)目的方法步驟，小編覺得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過來(lái)看看吧

1.打開IDEA,創(chuàng)建新項(xiàng)目，選擇Spring Initializr

2.輸入Artifact

3.勾選Web

4.點(diǎn)擊finish完成

5.進(jìn)入項(xiàng)目，可以將以下內(nèi)容刪除

pom.xml文件：

<?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.example</groupId> 
 <artifactId>springbootdemo</artifactId> 
 <version>0.0.1-SNAPSHOT</version> 
 <packaging>jar</packaging> 
 
 <name>springbootdemo</name> 
 <description>Demo project for Spring Boot</description> 
 
 <!--起步依賴--> 
 <parent> 
  <groupId>org.springframework.boot</groupId> 
  <artifactId>spring-boot-starter-parent</artifactId> 
  <version>1.5.2.RELEASE</version> 
  <relativePath/> <!-- lookup parent from repository --> 
 </parent> 
 
 <properties> 
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
  <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> 
  <java.version>1.8</java.version> 
 </properties> 
 
 <dependencies> 
  <!--開發(fā)web項(xiàng)目相關(guān)依賴--> 
  <dependency> 
   <groupId>org.springframework.boot</groupId> 
   <artifactId>spring-boot-starter-web</artifactId> 
  </dependency> 
  <!--springboot單元測(cè)試--> 
  <dependency> 
   <groupId>org.springframework.boot</groupId> 
   <artifactId>spring-boot-starter-test</artifactId> 
   <scope>test</scope> 
  </dependency> 
 </dependencies> 
 
 <!--maven構(gòu)建--> 
 <build> 
  <plugins> 
   <plugin> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-maven-plugin</artifactId> 
   </plugin> 
  </plugins> 
 </build> 
</project>

6.創(chuàng)建一個(gè)HelloController

package com.example; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RestController; 
@RestController 
public class HelloController { 
 @RequestMapping("/hello") 
 public String hello() { 
  return "hello,this is a springboot demo"; 
 } 
}

7.程序自動(dòng)生成的SpringbootdemoApplication，會(huì)有一個(gè)@SpringBootApplication的注解，這個(gè)注解用來(lái)標(biāo)明這個(gè)類是程序的入口

package com.example; 
 
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
 
//入口 
@SpringBootApplication 
public class SpringbootdemoApplication { 
 
 public static void main(String[] args) { 
  SpringApplication.run(SpringbootdemoApplication.class, args); 
 } 
}

@SpringBootApplication開啟了Spring的組件掃描和springboot的自動(dòng)配置功能，相當(dāng)于將以下三個(gè)注解組合在了一起

（1）@Configuration：表名該類使用基于Java的配置,將此類作為配置類

（2）@ComponentScan：?jiǎn)⒂米⒔鈷呙?/p>

（3）@EnableAutoConfiguration：開啟springboot的自動(dòng)配置功能

8.運(yùn)行SpringbootdemoApplication類
