spring boot 中如果存在公共类提取成的项目是没main方法类的，这时候就需要 排除掉main方法类

<build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>1.5.2.RELEASE</version>
                <configuration>
                    <skip>true</skip><!--不需要main类打包-->
                </configuration>
            </plugin>
            <!-- maven打包 跳过测试包 -->
			<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <skip>true</skip>
                </configuration>
            </plugin>

        </plugins>
    </build>
