エラーシーン:springboot開発環境、ssl+wssエラー
ネット上ではバグと呼ばれています.
そこでspringboot内蔵tomcatを直接アップグレード
元:

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

アップグレード後:

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

以上のシナリオではtomcat 8.x.xを9.x.xにアップグレードし、慎重に使用します.
