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

[warning] it is highly recommended to fix these problems because they threaten the stability of your build.
[warning] 
[warning] for this reason, future maven versions might no longer support building such malformed projects.
