How to open two ports in JAVA springboot

#Development environment configurationserver:
    # The server's HTTP port, default is 8080    port: 8080
# Add start    # https certificate configuration, if you don't write it, just two http ports    # Put the certificate in src/main/resources    ssl:
        key-store: classpath:Certificate name.pfx
        key-alias: alias
        key-store-password: Key
        key-store-type: PKCS12
# Add end    servlet:
        # The access path of the application        context-path: /
    tomcat:
        # tomcat's URI encoding        uri-encoding: UTF-8
        # The number of queues after the number of connections is full, the default is 100        accept-count: 1000
        threads:
            # tomcat maximum number of threads, default is 200            max: 800
            # Tomcat starts initialization number, default value is 10            min-spare: 100
