Spring Boot创建非可执行jar包的实例教程

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
