本文介绍如何从start.spring.io创建Spring Boot项目，并通过Eclipse进行配置和测试。文章详细记录了项目构建过程，包括pom.xml配置及使用Maven构建。

１２年开始正式从事软件研发工作．

先后从事windows media，linux流媒体开发，学习ocr，opencv，ffmpeg，srs，rtmp，rtsp，kurento

１．在start.spring.io网站上创建一个spring boot项目，选择合适的jdk和maven以及spring boot 版本．

２．打开eclipse，选择file　import 导入Demo项目．

３．打开DemoApplication.java文件，右键　选择Run As - Java Application

一起正常．

另外，为了测试web端显示．

需要修改两个文件.DemoApplication.java pom.xml

代码如下:

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.*;

@SpringBootApplication
@RestController
@EnableAutoConfiguration
public class DemoApplication {
    
    @RequestMapping("/")
    String home() {
        return "Hello World!";
    }

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

pom.xml　文件配置如下：

<?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">

            </plugin>
        </plugins>
    </build>

</project>

配置maven build

在Demo根目录上右键，选择Debug As-Debug Configurations

选择maven build子节点

最后，选择Ｄｅｍｏ项目根目录，右键选择Maven As -> Maven Build，查看Console控制台输出．

会在工程目录ｔａｒｇｅｔ下生成对应的demo-0.0.1-SNAPSHOT.jar文件．可以通过

java -jar demo-0.0.1-SNAPSHOT.jar运行项目，在浏览器输入

http://localhost:8443　查看网页输入．

备注：端口号设置，在/target/classes/application.properties 文件

由maven构建的war包，同样可以再windows平台cmd启动，命令 java -jar *.war 即可
