##### 本项目主要是讲创建一个SpringBoot的HelloWorld项目 #####

#### 项目地址：[https://github.com/Chakid/SpringBoot-example][https_github.com_Chakid_SpringBoot-example] ####

该项目直接以maven的方式创建

pom文件中导入相关包：

<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>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
    
        
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

创建SpringBoot启动类：

@SpringBootApplication
    public class MainApplication { 
    
        /** * Spring应用启动起来 */
        public static void main(String[] args) { 
            SpringApplication.run(MainApplication.class,args);
        }
    }

创建一个控制类

@Controller
    public class HelloController { 
    
    
        @ResponseBody
        @RequestMapping("/hello")
        public String hello(){ 
            return "Hello SpringBoot";
        }
    }

创建好相关类，具体代码可见项目中的实现，运行启动类；浏览器访问 [http://127.0.0.1:8080/hello][http_127.0.0.1_8080_hello]  
即可见到相关效果：
