一、springboot 打包时分离jar依赖

			<!--    
			<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            -->
			<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>3.1.1</version>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <classpathPrefix>lib/</classpathPrefix>
                            <mainClass>com.xx.XXXApplication</mainClass>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id>copy-lib</id>
                        <phase>package</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>target/lib</outputDirectory>
                            <excludeTransitive>false</excludeTransitive>
                            <stripVersion>false</stripVersion>
                            <includeScope>runtime</includeScope>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

如果只需要jar包分离，按照上面配置就可以了。（注意需要把spring-boot-maven-plugin插件注释掉）

二、使用maven-assembly-plugin组装打包结果（可选）

(注意：该步骤插件需要配置在上面的插件之后)

1. 设置依赖插件

			<plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>2.4.1</version>
                <configuration>
                    <descriptors>
                        <descriptor>src/main/assembly/assembly.xml</descriptor>
                    </descriptors>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

2. assembly.xml配置示例

<assembly>
	<id>Alpha</id>
	<formats>
		<format>tar.gz</format>
	</formats>
	<includeBaseDirectory>true</includeBaseDirectory>
	<fileSets>
		<fileSet>
			<directory>src/main/assembly/bin</directory>
			<outputDirectory>bin</outputDirectory>
		</fileSet>
		<fileSet>
			<directory>src/main/assembly/sql</directory>
			<outputDirectory>sql</outputDirectory>
		</fileSet>
		<fileSet>
			<directory>target</directory>
			<outputDirectory>main</outputDirectory>
			<includes>
				<include>dss.jar</include>
			</includes>
		</fileSet>
		<fileSet>
			<directory>target</directory>
			<outputDirectory></outputDirectory>
			<includes>
				<include>lib/*.jar</include>
			</includes>
		</fileSet>
		<fileSet>
			<directory>src/main/resources</directory>
			<outputDirectory>logs</outputDirectory>
			<excludes>
				<exclude>**/*</exclude>
			</excludes>
		</fileSet>
		<fileSet>
			<directory>src/main/resources</directory>
			<outputDirectory>word</outputDirectory>
			<excludes>
				<exclude>**/*</exclude>
			</excludes>
		</fileSet>
	</fileSets>
</assembly>

三、Jar包分离后的启动脚本

#!/bin/bash
nohup java -server -Xms2048m -XX:MetaspaceSize=128M -XX:MaxMetaspaceSize=2048M -Djava.ext.dirs=../lib:$JAVA_HOME/jre/lib/ext -Dspring.config.location=../application.properties -jar ../xxxxxx-RELEASE.jar &
