排查后发现S是因为加入了jasper依赖

<!--jetty容器这句不需要!!! 会报错-->
        <!--加入支持JSP的依赖-->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
        </dependency>
<!--jetty容器这句不需要!!! 会报错-->

将其去掉即可。

总结:此类启动报错,大多是依赖jar包不全或者冲突或者依赖多了。
