- 创建一个Maven项目
eclipse右键新建Maven Project
默认一直下一步即可 - 修改pom.xml
4.0.0
cn.moexc
boot
0.0.1-SNAPSHOT
jar
boot
http://maven.apache.org
UTF-8
org.springframework.boot
spring-boot-starter-parent
2.0.5.RELEASE
org.springframework.boot
spring-boot-starter
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-devtools
true
org.springframework.boot
spring-boot-maven-plugin
true
等待jar包下载完毕....
新建yml文件
在/src/main/resources目录下新建一个application.yml并填写：
server:
#监听端口
port: 80
servlet:
#工程名
context-path: /boot
- 修改启动类
启动类添加注解@SpringBootApplication
把main方法中修改为
SpringApplication.run(App.class, args);
完整的启动类：
package cn.moexc.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Hello world!
*
*/
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
-
右键启动
启动... 控制台输出：

当然还有更简单方法：
只需要填写项目名就可以，还可以按照需要构造pom，一步到位：在线生成
OK :)
