1.首先打开eclipse，创建一个Maven项目，如图所示的项目结构

2.在src/main/resources目录下创建一个application.properties文件（如过需要修改端口号的话），在里面加上一句话即可

//这个端口号是可以随意写的，只要不冲突就行
    server.port=8888

3.在pom.xml中添加各种包的依赖

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.0.1.RELEASE</version>
            <relativePath />
        </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>
            
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

4.在src/main/java路径下创建com.light.springboot类路径，添加一个SpringbootApplication.java带main方法的类，

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

5.创建一个package,如：com.light.springboot.controller，编写一个简单的controller类，

@RestController
    public class TestController {
        @GetMapping(value = "/helloworld")
        public String helloworld() {
            return "helloworld";
        }
    }

6.右键启动SpringbootApplication.java类，出现      Started SpringbootApplication in 3.16 seconds (JVM running for 3.582) 字样，即启动成功！

在浏览器中输入localhhost:/helloworld
