一个简单的SpringBoot入门程序

1. 使用IDEA构建Maven项目

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <project xmlns="http://maven.apache.org/POM/4.0.0"
 3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 5     <modelVersion>4.0.0</modelVersion>

 7     <groupId>cn.burgundy</groupId>
 8     <artifactId>springboot-cheatsheep</artifactId>
 9     <version>1.0-SNAPSHOT</version>
10 
11     <!-- 继承SpringBoot插件 -->
12     <parent>
13         <groupId>org.springframework.boot</groupId>
14         <artifactId>spring-boot-starter-parent</artifactId>
15         <version>1.3.3.RELEASE</version>
16     </parent>
17 
18     <dependencies>
19         <!-- 启动springBoot web启动器 -->
20         <dependency>
21             <groupId>org.springframework.boot</groupId>
22             <artifactId>spring-boot-starter-web</artifactId>
23         </dependency>
24     </dependencies>
25 
26     <build>
27         <plugins>
28             <!-- 使用maven启动springboot -->
29             <plugin>
30                 <groupId>org.springframework.boot</groupId>
31                 <artifactId>spring-boot-maven-plugin</artifactId>
32             </plugin>
33         </plugins>
34     </build>
35 </project>

2. 创建SpringBoot启动类

 1 /**
 2  * Created by IntelliJ IDEA.
 3  *
 4  * @Auther: ShaoHsiung
 5  * @Date: 2018/8/29 11:11
 6  * @Title: 一个简单的SpringBoot应用
 7  * @Description: SpringBoot启动类
 8  */
 9 @SpringBootApplication
10 public class HelloApp {
11     public static void main(String[] args) {
12         SpringApplication.run(HelloApp.class, args);
13     }
14 }

备注:

1) @SpringBootApplication

2) SpringApplication.run(HelloApp.class, args);

3. 创建第一个Controller

 1 /**
 2  * Created by IntelliJ IDEA.
 3  *
 4  * @Auther: ShaoHsiung
 5  * @Date: 2018/8/29 11:14
 6  * @Title: 一个简单的SpringBoot应用
 7  * @Description: 第一个controller
 8  */
 9 @RestController
10 public class HelloController {
11     @RequestMapping(method = RequestMethod.GET, path = "/hello")
12     public String hello() {
13         return "Hello SpringBoot";
14     }
15 }
