1.下載maven並解壓 http://maven.apache.org/ 2.配置eclipse中要使用maven,將maven解壓好的路徑配置進來 Window->Preferences->Maven->Installations->add 3.配置要使用的maven的setting配置檔案(在maven的conf目錄下)，local Repository本地倉庫沒有的話就預設就行 如果需要指定jdk版本需要在setting中新增

<profiles>
	<profile>    
    <id>jdk-1.8</id>
 

    <activation>
        <activeByDefault>true</activeByDefault>
        <jdk>1.8</jdk>
    </activation>
    <properties>   
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target
 
>
    <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
    </properties>
	</profile>
</profiles>

4.在eclipse中新建maven工程 (1).new maven Project (2).選擇預設 (3).選擇quickstart (4)設定工程名 (5)工程建立成功 如果程式中不出現src/main/java,src/test/java等，需要為工程設定正確的jre（建議是選裝好的jdk路徑，因為spring boot打包成jar包需要jdk） 即右鍵工程->properties->java Build Path

<parent>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>2.0.3.RELEASE</version>
	<relativePath />
</parent>
<dependencies>
	<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
</dependencies>

6.建立hello world測試 (1)建立兩檔案，HelloSpringboot.java和MainApplication.java(主函式)

HelloSpringboot.java

package com.haha.SpringbootTest.controller;

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

@Controller
public class HelloSpringboot {

	@RequestMapping("/hello")
	@ResponseBody
	public String hello()
	{
		return "hellow world";
	}
}

MainApplication.java

package com.haha.SpringbootTest;

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

@SpringBootApplication
public class MainApplication {

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

2.在MainApplication.java中執行工程，然後在瀏覽器輸入http://localhost:8080/hello
