SpringBoot项目打包分离lib包与配置文件

### 1. 不分离打包（默认） ###

SpringBoot初始化建立项目默认的`spring-boot-maven-plugin`插件，进行项目打包，这个插件会将项目所有的依赖打入`BOOT-INF/lib`下，`pom`文件配置如下：

<build>
    		<plugins>
    			<plugin>
    				<groupId>org.springframework.boot</groupId>
    				<artifactId>spring-boot-maven-plugin</artifactId>
    			</plugin>
    		</plugins>
    	</build>

`package`打包后，打出的是完整的可运行的`jar`包，根据项目的不同大小不同，整体来说是比较大的。

### 2. 分离打包 ###

替换为`maven-jar-plugin`打包插件，`pom`文件修改如下：

<build>
    		<plugins>
    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-jar-plugin</artifactId>
    				<configuration>
    					
    					<excludes>
    						<exclude>*.properties</exclude>
    						<exclude>*.yml</exclude>
    						<exclude>*.yaml</exclude>
    					</excludes>
    					<archive>
    						<manifest>
    							
    							<mainClass>com.dcxuexi.Springboot03JarApplication</mainClass>
    							
    							<addClasspath>true</addClasspath>
    							
    							<classpathPrefix>lib/</classpathPrefix>
    							
    							<useUniqueVersions>false</useUniqueVersions>
    						</manifest>
    						<manifestEntries>
    							
    							<Class-Path>config/</Class-Path>
    						</manifestEntries>
    					</archive>
    				</configuration>
    			</plugin>
    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-dependency-plugin</artifactId>
    				<executions>
    					<execution>
    						<id>copy</id>
    						<phase>package</phase>
    						<goals>
    							<goal>copy-dependencies</goal>
    						</goals>
    						<configuration>
    							<outputDirectory>${project.build.directory}/lib/</outputDirectory>
    						</configuration>
    					</execution>
    				</executions>
    			</plugin>
    
    			<plugin>
    				<artifactId>maven-resources-plugin</artifactId>
    				<executions>
    					<execution>
    						<id>copy-resources</id>
    						<phase>package</phase>
    						<goals>
    							<goal>copy-resources</goal>
    						</goals>
    						<configuration>
    							<resources>
    								
    								<resource>
    									<directory>src/main/resources/</directory>
    									<includes>
    										<include>*.properties</include>
    										<include>*.yml</include>
    										<exclude>*.yaml</exclude>
    									</includes>
    								</resource>
    							</resources>
    							<outputDirectory>${project.build.directory}/config</outputDirectory>
    						</configuration>
    					</execution>
    				</executions>
    			</plugin>
    		</plugins>
    	</build>

先后分别双击执行`clean`和`package`命令，进行清理和打包。

打包后的结构如下：

使用命令`java -jar .\springboot_03_jar-0.0.1-SNAPSHOT.jar`启动jar

这样就完成了配置文件以及`lib`包和`jar`的分离了，并且`jar`在运行的时候会默认去读取`config`文件夹中的配置，修改起来非常方便。
