我们经常会有这种场景，只需要把Spring Boot打成普通的jar包，不包含配置文件，供其他程序应用
本文介绍如何使用Maven将Spring Boot应用打成普通的非可执行jar包。
配置maven-jar-plugin
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <classifier>exec</classifier> </configuration> </plugin> <plugin> <artifactId>maven-jar-plugin</artifactId> <executions> <execution> <id>exec</id> <phase>package</phase> <goals> <goal>jar</goal> </goals> <configuration> <classifier>exec</classifier> </configuration> </execution> <execution> <phase>package</phase> <goals> <goal>jar</goal> </goals> <configuration> <!-- Need this to ensure application.yml is excluded --> <forceCreation>true</forceCreation> <excludes> <exclude>application.yml</exclude> </excludes> </configuration> </execution> </executions> </plugin> </plugins></build>
执行mvn clean package打包
