springboot打包与依赖包分离
前言:
springboot项目部署时,需要本地打包成一个jar放到服务器进行部署(使用jenkins自动打包部署同理),部署包里包含了其它所有依赖包,整个包会比较大,小则几M,大则几十上百。
正文:
1、pom文件plugins标签中添加以下内容
<!-- 去除配置文件,启动时默认指定外置config目录下的配置文件 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<excludes>
<exclude>*.properties</exclude>
<exclude>*.xml</exclude>
<exclude>*.yml</exclude>
</excludes>
</configuration>
</plugin>
<!-- 指定启动类,打包去除依赖包 -->
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>com.bangdao.parking.ordercenter.Application</mainClass>
<layout>ZIP</layout>
<includes>
<include>
<groupId>nothing</groupId>
<artifactId>nothing</artifactId>
</include>
</includes>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
<!-- 指定jdk版本 -->
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<!-- 打包指定依赖包的目录 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
2、本地打包


3、在服务器上部署文件夹内新建lib目录,并将本地locallib(见上图)copy到新建的lib目录【注:只有在第一次部署时才需要复制】
4、指定依赖包目录,执行启动命令
nohup java -Dloader.path='lib/' -jar applets-api.jar &
从此可以开心的部署了,网络传输慢也可以轻松搞定。
未来的事,谁也说不准,活在当下!
