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
leaves project url:http://github.com/wunanyu/leaves
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
pom.xml
leaves项目pom.xml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>
<addClasspath>true</addClasspath>
<!-- 指定包含的依赖文件位置 -->
<classpathPrefix>lib/</classpathPrefix>

</manifest>
</archive>
</configuration>
</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
tar.gz 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tar.gz
