springboot项目报错

写的一个springboot小项目，打的jar包在服务器上跑着，在没人访问的情况下会报这个错误。但是tomcat服务并不会结束，还可以正常使用。这个是什么问题呢？项目只使用了SSM，其他的都没使用。

这个是部分配置文件，因为安装了ssl证书，会将http转发为https

@Configuration
public class HttpsConfig {

    @Bean
    public TomcatServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint constraint = new SecurityConstraint();
                constraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                constraint.addCollection(collection);
                context.addConstraint(constraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(httpConnector());
        return tomcat;
    }

    private Connector httpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        // Connector 监听的 http 的端口号
        connector.setPort(8090);
        connector.setSecure(false);
        // 监听到http的端口号后转向到的https的端口号
        connector.setRedirectPort(443);
        return connector;
    }

}

出现了http，你不会是https访问的接口吧;
我擦，还真是；如果只是自己玩，没必要搞https

安装个nginx 转发下到tomcat http/https都能兼顾到，那需要在tomcat上做文章啊。性能也不合适啊
