自动装配在构造的情况下，与插座

Question

我的主要代码

public static void main(String[] args) { 
    System.out.println("Hello World!"); 
    ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
      "DataSource.xml"); 
    App app = applicationContext.getBean(App.class); 
    app.start(); 
} 

而且我做起方法

public void start() { 

    try { 
     ServerSocket mobCom = new ServerSocket(9846); 
     ExecutorService executorService = Executors.newCachedThreadPool(); 

     while (true) { 
      Socket socket = mobCom.accept(); 
      PortService portService = new PortService(socket); 
      executorService.submit(portService); 
     } 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

} 

参数，但我想从春天创建PortService对象，而不是直接，因为它有db通信类。我该怎么做。

我已经这样做，在过去实现了这个 -

您PortService实现一个工厂类。

@Service 
public class PortServiceFactory { 
    private SomeObject someObject; 

    @Autowired 
    public PortServiceFactory(SomeObject someObject) { 
     this.someObject = someObject; 
    } 

    public PortService getPortService(Socket socket) { 
     return new PortService(someObject, socket); 
    } 
} 

Autowire此工厂在你的类，你有那个start（）方法。

更换

PortService portService = new PortService(socket); 

与

PortService portService = portServiceFactory.getPortService(socket);
