SpringBoot 增量部署发布的实现步骤

<!--1.打包当前web项目-->
<plugin>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-maven-plugin</artifactId>
	<configuration>
		<!-- 指定该jar包启动时的主类-->
		<mainClass>com.rc114.bms.RbApplication</mainClass>

		<!-- 模块打包需要增加这个配置,带exec的为可执行jar,不带的为可引用jar-->
		<classifier>exec</classifier>
		<includeSystemScope>true</includeSystemScope>

		<!--必须为ZIP模式，不指定的话-Dloader.path不生效-->
		<layout>ZIP</layout>

		<!-- 打包的时候排除的jar包-->
		<includes>
			<include>
				<groupId>non-exists</groupId>
				<artifactId>non-exists</artifactId>
			</include>
		</includes>
	</configuration>
</plugin>

<!--2.打包依赖项-->
<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-dependency-plugin</artifactId>
	<version>3.2.0</version> <!-- 使用适合你的版本 -->
	<executions>
		<execution>
			<id>copy-dependencies</id>
			<phase>prepare-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>

<build>
