默認狀況下,插件 spring-boot-maven-plugin
會把整個項目打包成一個可運行的Jar包(即所謂的Flat Jar),致使了這個Jar包很大(一般有幾十M+)。現在迭代發佈時常有的事情,每次都上傳一個如此龐大的文件,會浪費不少時間,有些時候上傳的過程當中還會出錯。java
形成Jar包很大的根本緣由就是依賴第三方的jar不少,很大,下面咱們就把第三方的JAR與項目代碼分離,第三方的JAR把移除到lib文件夾中,便可實現爲咱們的可執行JAR瘦身,配置以下:spring
<plugins> <!-- spring boot thin jar configuration --> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <!-- main 入口 --> <mainClass>com.bdfint.logistics.app.driver.LogisticsAppDriverApplication</mainClass> <!-- 設置爲ZIP,此模式下spring-boot-maven-plugin會將Manifest.MF文件中的Main-Class設置爲org.springframework.boot.loader.PropertiesLauncher --> <layout>ZIP</layout> <!-- 須要包含的jar包 --> <includes> <!-- 不包含任何jar包 --> <!--<include>--> <!--<groupId>nothing</groupId>--> <!--<artifactId>nothing</artifactId>--> <!--</include>--> <include> <groupId>com.bdfint.logistics</groupId> <artifactId>logistics-api</artifactId> </include> <include> <groupId>com.bdfint.logistics</groupId> <artifactId>logistics-common</artifactId> </include> </includes> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> <!-- third-party jar into lib directory --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>copy-dependencies</id> <phase>prepare-package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <outputDirectory>${project.build.directory}/lib</outputDirectory> <!-- 須要排除的jar的 groupId --> <excludeGroupIds> com.bdfint.logistics </excludeGroupIds> </configuration> </execution> </executions> </plugin> </plugins>
接下來,執行打包命令:mvn clean package -Dmaven.test.skip=true,打包後在target目錄下就包含咱們的JAR和lib目錄,以下圖:apache
CMD定位到target目錄下,執行命令:java -Dloader.path=./lib -jar logistics-app-driver-2.9.1.1.jar,便可把項目JAR跑起來!api
