从Spring Boot 2.1.0.RELEASE更新到2.1.1.RELEASE之后，所有HTTPS请求均失败，并显示以下错误：

恢复到2.1.0.RELEASE解决了该问题。

• 作业系统：Ubuntu 18.04.1 LTS
• Java：OpenJDK运行时环境（内部版本10.0.2 + 13-Ubuntu-1ubuntu0.18.04.4）
• 解放：1.2.16-1build1

怀疑与此有关：https :

boot/issues/15261

明确锁定对tomcat-embed-core 9.0.12的依赖关系可以解决此问题。

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-core</artifactId>
            <version>9.0.12</version>
        </dependency>
    </dependencies>
</dependencyManagement>

怀疑libtcnative更新也可以解决该问题，但是Ubuntu LTS的当前版本是1.2.16-1build1，因此我们认为这是Spring
Boot中的回归。

https://packages.ubuntu.com/search?keywords=libtcnative-1

上面列出的依赖项锁定已解决问题。
