Spring Boot 之Hello Word
Spring Boot官网:http://projects.spring.io/spring-boot/
环境准备:maven 3.3.5、jdk8、Idea
1.创建maven项目工程
2.引入starters
1 <parent> 2 <groupId>org.springframework.boot</groupId> 3 <artifactId>spring-boot-starter-parent</artifactId> 4 <version>1.5.11.RELEASE</version> 5 </parent> 6 <dependencies> 7 <dependency> 8 <groupId>org.springframework.boot</groupId> 9 <artifactId>spring-boot-starter-web</artifactId> 10 </dependency> 11 </dependencies>
3.创建主程序
1 @SpringBootApplication 2 public class HelloWorldMainApplication { 3 4 public static void main(String[] args){ 5 //Spring 应用启动起来 6 SpringApplication.run(HelloWorldMainApplication.class, args); 7 } 8 }
4.创建一个Controller
1 @Controller 2 public class HelloController { 3 4 @RequestMapping("/hello") 5 @ResponseBody 6 public String hello(){ 7 return "Hello Word!"; 8 } 9 }
5.运行主方法,并在浏览器输入:localhost:8080/hello ,就会出现Hello Word!
6.也可以打包成jar包 进行部署
url:https://docs.spring.io/spring-boot/docs/1.5.11.RELEASE/reference/htmlsingle/#getting-started-first-application-executable-jar
这个插件,可以将应用打包成一个jar包
1 <build> 2 <plugins> 3 <plugin> 4 <groupId>org.springframework.boot</groupId> 5 <artifactId>spring-boot-maven-plugin</artifactId> 6 </plugin> 7 </plugins> 8 </build>
