java -jar your-application.jar

set SERVER_PORT=8081
java -jar your-application.jar

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class ServerPortConfig {

    @Value("${server.port}")
    private int port;

    public int getPort() {
        return port;
    }
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.stereotype.Component;

@Component
public class ServerPortConfig {

    @Autowired
    private Environment env;

    public int getPort() {
        return env.getProperty("server.port", Integer.class, 8080); // 默认端口为8080
    }
}
