直接在IDEA里面运行SpringBoot启动类是可以正常访问的，但是使用mvn install打包后，报出如下错误：

java.lang.ClassNotFoundException: cn.licoy.service.entity.User
        at java.net.URLClassLoader.findClass(Unknown Source) ~[na:1.8.0_131]
        at java.lang.ClassLoader.loadClass(Unknown Source) ~[na:1.8.0_131]
        at org.springframework.boot.loader.LaunchedURLClassLoader.loadClass(LaunchedURLClassLoader.java:94) ~[rest-0.1.jar:0.1]

其中,Springboot启动包是rest包，当中引用了service包中的User类，在打包之后的rest.jar里面lib目录下有service.jar，但是一访问就找不到类

解决方法：要给被依赖的module的pom.xml中添加

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.bootgroupId>
                <artifactId>spring-boot-maven-pluginartifactId>
                <configuration>
                    <classifier>execclassifier>
                configuration>
