maven exec plugin启动springboot应用并且change port更改端口（多模块）

<!--在子模块的pom中添加-->
 <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <version>3.2.0</version> 		
		<configuration>
          <executable>java</executable>
          <arguments>
            <argument>-classpath</argument>
            <!-- automatically creates the classpath using all project dependencies,
                 also adding the project build directory -->
            <classpath/>
              <argument>-Dserver.port=8081</argument> 
            <argument>com.rf.wxshop.WxshopApplication</argument>
          </arguments>
        </configuration>
</plugin>

mvn exec:exec

多模块时，假设wxshop-main 为子模块
首先需要将所有模块安装到本地（会安装parent pom中的dependencies)

mvn install -pl wxshop-main -am

然后执行命令

mvn exec:exec -pl wxshop-main
