是否可以将非托管参数/bean 参数与@value 和/或 spring 托管 bean 一起传递

Question

I think this is not possible and possibly breaking the Spring-managed bean concept. Basically, right now I am initializing beans (multiple beans of the same class in some cases based on constructor args) from the @SpringBootApplication class. eg

@SpringBootApplication
public class App  { 
  @Autowired
  private Registry registry;
  
  @Autowired
  private Gson gson;
  
  @Bean(name="AtlantaClient")
  public Client atlantaClient() throws URISyntaxException, InterruptedException {
      var address = "ws://" + atlantaIP + ":" + atlantaPort;          
      Client client = new Client(address, gson, registry);
      client.connect();   
      return client;
  }
  
  @Bean(name="MumbaiClient")
  public Client mumbaiClient() throws URISyntaxException, InterruptedException {
      var address = "ws://" + mumbaiIP + ":" + mumbaiPort;        
      Client client = new Client(address, gson, registry);
      client.connect();   
      return client;
  }  
}

So rather than specifying Registry and Gson as Autowired here in App class, can I somehow use/inject directly in Client 's constructor along with address??

Not sure, if that's what you want, but you can specify such bean dependencies directly as method arguments in the @Bean methods:

@SpringBootApplication
public class App {

    @Bean(name = "AtlantaClient")
    public Client atlantaClient(Registry registry, Gson gson) throws URISyntaxException, InterruptedException {
        var address = "ws://" + atlantaIP + ":" + atlantaPort;
        Client client = new Client(address, gson, registry);
        client.connect();
        return client;
    }

    @Bean(name = "MumbaiClient")
    public Client mumbaiClient(Registry registry, Gson gson) throws URISyntaxException, InterruptedException {
        var address = "ws://" + mumbaiIP + ":" + mumbaiPort;
        Client client = new Client(address, gson, registry);
        client.connect();
        return client;
    }
}
