原因分析：

分析猜想：1、pom文件缺少依赖 2、找不到webServerStartStop的bean

全局搜org.wildfly.common 发现在pom文件中，其被排除了；奇怪，我没有手动加exclusions，噢，可能是因为之前选中想要忽略的类右键->Mark Derictory as -> excluded时，idea自动加了exclusion

解决方案：

提示：这里填写该问题的具体解决方案：

在pom.xml中注释或者删除exclusions：

<!--            <exclusions>-->
<!--                <exclusion>-->
<!--                    <artifactId>wildfly-common</artifactId>-->
<!--                    <groupId>org.wildfly.common</groupId>-->
<!--                </exclusion>-->
<!--            </exclusions>-->
