出错场景：springboot开发环境，ssl+wss报错

网上说是一个bug：

于是直接升级springboot内置tomcat

原来：

 <parent>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-parentartifactId>
        <version>2.0.2.RELEASEversion>
        <relativePath/> 
    parent>

升级后：

 <parent>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-parentartifactId>
        <version>2.1.6.RELEASEversion>
        <relativePath/> 
    parent>

以上方案会把tomcat8.x.x升级到9.x.x,慎重使用。
