本文详细介绍如何将SpringBoot项目打成可独立运行的jar包，包括修改Application类以继承SpringBootServletInitializer，以及在pom.xml中配置必要的插件和参数。通过遵循这些步骤，可以简化部署流程。

因Spring Boot自带服务器，所以只需打成jar即可。

步骤如下：

1. 修改*Application.java文件，使其继承[SpringBootServletInitializer]类，并重写[configure]方法

package com.chyer.apigateway;

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;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@EnableEurekaClient
@RestController
public class ApiGatewayApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(ApiGatewayApplication.class, args);
    }

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

2. 修改pom.xml文件，追加2个插件（如报缺少servlet包，可自行引入）
