嫺熟類<E>成Class <E[]>

Question

public abstract class AbstractRESTClientService<E extends IDable<String>> 
    implements GenericService<E, String> { 


    private Class<E> classType; 
    private Class<E[]> classArray; 
    private String controllerPath; 

    public AbstractRESTClientService(final Class<E> classType, 
     final Class<E[]> classArray, 
     final String controllerPath) { 
      this.classType = classType; 
      this.classArray = classArray; 
      this.controllerPath = controllerPath; 
      this.webService = new GenericWebClientService<E>(); 
     } 

    // ... other methods 
} 

有沒有一種方法來操縱classType所成classArray這樣我不需要classArray以作爲參數傳遞？

Answer 1

我不想認爲這是做到這一點的最佳方式，但以下是我如何處理它。

public abstract class AbstractRESTClientService<E extends IDable<String>> 
    implements GenericService<E, String> { 


private Class<E> classType; 
private Class<E[]> classArray; 
private String controllerPath; 

@SuppressWarnings("unchecked") 
public AbstractRESTClientService(final Class<E[]> classArray, 
    final String controllerPath) { 
     this.classType = (Class<E>) classArray.getComponentType(); 
     this.classArray = classArray; 
     this.controllerPath = controllerPath; 
     this.webService = new GenericWebClientService<E>(); 
    } 

    // ... other methods 
}
