你知道springboot+maven的打包骚操作吗?

## 前言 ##

本人在公司担任的活儿比较杂,包括部署上线,调试都是自己干.那么在项目打包部署遇到以下困扰

1.  项目打包,代码本身不多,但是依赖太重,导致打出的jar包很大,上传到服务器比较慢
2.  配置文件打包到jar包内部,不便于调试修改

这是一个springboot+maven写的demo,主要演示springboot项目通过maven插件,将依赖与配置文件打包到jar包外部,实现灵活的项目管理.仅供参考学习  
方法总比问题多,觉得我这个办法比较low的,请不要往下看

*  适用场景:内网项目
 *  如果是外网项目建议用更优雅的解决方案,比如使用脚本拉取代码,用配置中心动态修改配置.

         *  三.代码参考

### 一.创建SpringBoot项目 ###

1.用idea新建项目  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nvcmxlb25lXzRldmVy_size_16_color_FFFFFF_t_70]2.填写项目信息  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nvcmxlb25lXzRldmVy_size_16_color_FFFFFF_t_70 1]3.这里勾选spring web 版本选择低版本

4.选择 项目名,然后finish

5.新建一个TestController,写先经典的hello world  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nvcmxlb25lXzRldmVy_size_16_color_FFFFFF_t_70 4]

package xyz.hashdog.pk;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class TestController { 
        @RequestMapping("test")
        public String test(){ 
            return "hello world";
        }
    }

6.配置文件改一下端口

server.port=4567

7.启动项目

8.成功访问接口  
http://localhost:4567/test  
![在这里插入图片描述][2020043015253032.png]

### 二.项目打包 ###

1.执行package打包(默认打包到target目录)  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nvcmxlb25lXzRldmVy_size_16_color_FFFFFF_t_70 6]2.修改pom文件  
去掉原有的spring-boot-maven-plugin  
将pom.xml中的plugin修改为

<plugins>
                
                <plugin>

3.执行package,将整个项目打包到app目录下了

4.将config中properties配置文件端口改为4568,的启动jar文件
