SpringBoot项⽬部署的打包⽅式（maven）项⽬使⽤maven打包
在springboot 项⽬中，将项⽬打包部署到服务器，使⽤maven的⽅式很常见，此处⽤到assembly插件
在项⽬代码写好，运⾏没有问题后，就可以将项⽬打包，部署到服务器
mvn
mvn是maven命令
常见的有
mvn clean # 清空maven输出（打包内容）
mvn install #项⽬打包并且放⼊maven仓库
mvn package # 项⽬打包
还可以⼀起使⽤，如 mvn clean install #先清空maven 项⽬输出，再install 打包项⽬
result
leaves项⽬l配置⽂件如下(使⽤assembly插件将配置⽂件与jar⽂件分开)

打包⽅式
所有⽂件打成⼀个包
包括依赖的jar⽂件，保持springboot-maven启动时初始样⼦就好，什么也不⽤配置
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
⽂件⼤⼩为 30M左右，因为包括依赖jar包，全部打包进⼀个jar⽂件中
依赖放在lib包
将⾃⼰写的源码分开打成⼀个jar包，依赖jar⽂件统⼀放在lib⽬录下
<!-- 将⾃⼰的项⽬代码打包成jar⽂件 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>

</archive>
</configuration>
</plugin>

<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
项⽬源代码⽣成的jar包⽂件⼤⼩只有27KB
其他依赖放⼊lib⽬录
配置⽂件外置，依赖放到lib⽬录
虽然前⾯配置已经做到将依赖jar⽂件与项⽬jar⽂件区分开，但是配置⽂件依然在项⽬jar⽂件内，有些时候，只是需要改动配置⽂件，⽽不需要修改源代码，因此配置⽂件放在jar⽂件外，会⽅便些。这⾥配置项⽬单独打包jar包，并提取config配置⽂件到项⽬jar包外⾯
assembly输出
< 压缩内容
config
lib为依赖jar包⽬录，config配置⽂件⽬录，leaves-0.0.1.jar 项⽬class⽂件
这⾥⽤到 assembly插件，
1.将依赖jar包，放到lib⽬录，
2.本⾝项⽬单独⽣成jar包，放到根⽬录，并排除配置⽂件，
3.将项⽬配置⽂件放到config⽬录下（jar⽂件外，可以动态修改）
4.将上⾯三个分类⽂件统⼀打包压缩放⼊⼀个⽂件中
