Consider defining a bean of type 'com.corundumstudio.socketio.SocketIOServer' in your configuration.

To define a bean of type 'com.corundumstudio.socketio.SocketIOServer' in your configuration, you can follow these steps:

1. Add the necessary dependency to your project. If you are using Maven, you can include the following in your `pom.xml`:

<dependency>
    <groupId>com.corundumstudio.socketio</groupId>
    <artifactId>netty-socketio</artifactId>
    <version>1.7.17</version>
</dependency>

Make sure to replace the version with the appropriate one for your project.

2. Create a configuration class, for example, `SocketIOConfig`, and annotate it with `@Configuration`.

3. In the `SocketIOConfig` class, define a bean of type `com.corundumstudio.socketio.SocketIOServer`. You can do this by creating a method annotated with `@Bean`, and returning an instance of `SocketIOServer`. For example:

@Configuration
public class SocketIOConfig {

    @Bean
    public SocketIOServer socketIOServer() {
        Configuration config = new Configuration();
        // Configure the server settings, such as hostname and port
        config.setHostname("localhost");
        config.setPort(8080);
        
        // Customize other server settings if needed
        
        return new SocketIOServer(config);
    }
}

In this example, the `SocketIOServer` bean is created with a basic configuration, setting the hostname to "localhost" and the port to 8080. You can customize these settings as per your requirements.

4. Now you can use the `SocketIOServer` bean in other parts of your application by autowiring it where needed. For example, you can inject it into a service class:

@Service
public class MySocketService {

    private final SocketIOServer socketIOServer;

    @Autowired
    public MySocketService(SocketIOServer socketIOServer) {
        this.socketIOServer = socketIOServer;
    }
    
    // Use the socketIOServer instance in your methods
}

Remember to annotate the class where you use the `SocketIOServer` bean with `@Service` or `@Component`, depending on your use case.

Make sure to adjust the configuration and usage of the `SocketIOServer` according to your specific needs.
