Springboot打包(一) jar包

1.配置server端口：

server:
    port: 8080

2.在Maven中指定启动类，打包方式

<packaging>jar</packaging>

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.example.XXX.XXX.DemoApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>

3.在启动类当中加上extends SpringBootServletInitializer并重写configure方法

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringDemoApplication extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(SpringDemoApplication .class, args);
    }

    @Override//为了打包springboot项目
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(this.getClass());
    }
}

4.运行mvn clean 再 mvn install
