在 Web 服務中返回 java.util.List

Question

I try to create a Bottom up Java bean Web Service in eclipse and I need to return a java.util.List so I have this on the server

public class BookStoreWS {
    private Book book1;
    private List<Book> listOfBooks;

    public Book getBook(){
        return  book1;
    }
    public List<Book> getBooks(){
        return  listOfBooks;
    }
}

這在客戶端

public static void main(String[] args) {
    BookStoreWSStub stub = new BookStoreWSStub();
    GetBookResponseDocument gbrd = stub.getBook();
    Book book = gbrd.getGetBookResponse().getReturn();//OK

    GetBooksResponseDocument gbrd2 = stub.getBooks();
    XmlObject OMGIAMNOTALIST = gbrd2.getGetBooksResponse().getReturn();//BAD
}

所以getBook()返回我想要的 object Book但getBooks()返回XmlObject而不是List<Book>

獲取List<Book>而不是XmlObject的任何簡單方法？ 或者將XmlObject轉換為List<Book> ？

Answer 1

那是你要找的嗎？

List<A> OMGIAMALIST = new ArrayList<A>();
OMGIAMALIST.addAll(stub.getAs());

for ( A item : OMGIAMALIST ) {
    XmlObject OMGIAMANITEM = item.getGetAsResponse().getReturn();
}

XmlObject （很可能）不能是 A，但 item 肯定是。
