參考:spring官方文檔 spring官網: spring.io
- idea 創建一個基礎maven工程
- 編輯創建工程的 pom文件如下:
- 工程繼承
spring-boot-starter-parent <!-- Inherit defaults from Spring Boot --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.0.RELEASE</version> </parent>
- 加入spring boot 工程啓動依賴
-
<!-- Add typical dependencies for a web application --> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies>
-
- 工程繼承
- 創建工程啓動類:
- Application.java
- 加上註解
@SpringBootApplication
- 如果當前啓動類沒有在對應controller同包下需要加上包掃描
@ComponentScan("org.yasser.controller")
- 加上註解
- Application.java
- 添加配置文件 application.yml 文件
- 創建controller類
controller:
package org.yasser.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* SLOGAN: 做一個會寫四種茴,笨且自律的人
*
* @Author Yasser
* @Date 2019-11-05
* @Description
*/
@RestController
public class HelloWorldController {
@GetMapping("hello-world")
public String helloWorld() {
return "hello world!";
}
}
application.yml:
server:
port: 8081
spring:
application:
name: yasser-spring-boot
Application.java :
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
/**
* SLOGAN: 做一個會寫四種茴,笨且自律的人
*
* @Author Yasser
* @Date 2019-11-05
* @Description
*/
@SpringBootApplication
@ComponentScan("org.yasser.controller")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
