springboot打包jar运行

修改pom.xml文件:

增加

<packaging>jar</packaging>

增加build配置:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <mainClass>com.example.tioncico.TioncicoApplication</mainClass><!--自己项目的启动类-->
            </configuration>
        </plugin>
    </plugins>
</build>

修改启动类:

package com.example.tioncico;

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;

//springboot 应用启动类的标识
@SpringBootApplication
//继承SpringBootServletInitializer 用于springboot内部启动tomcat,并且可自定义端口号,项目名
public class TioncicoApplication extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(this.getClass());
    }
}

maven编译打包

编译打包成功之后,会在根目录生成target目录:

使用java -jar ./target/xxx.jar即可运行:

修改端口

在appliation.properties 中增加:

server.port=9090

重新打包即可根据新端口运行:
