修改启动类文件，重配置一下tomcat

@Configuration
public class TomcatConfig {
    @Value("${server.http.port}")
    private int httpPort;

    @Bean
    public ServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
        tomcat.addAdditionalTomcatConnectors(createStandardConnector()); // 添加http
        return tomcat;
    }

    private Connector createStandardConnector() {
        Connector connector = new Connector(TomcatServletWebServerFactory.DEFAULT_PROTOCOL);
        connector.setPort(httpPort);
        return connector;
    }
}
