JAX-WS：如何使SOAP响应返回HashMap对象

为了帮助JAXB，您可以将您的“包装”

HashMap

@XmlJavaTypeAdapter

public class Response {    @XmlJavaTypeAdapter(MapAdapter.class)        HashMap<Integer, Book> books;    public HashMap<Integer, Book> getBooks() {        return mapProperty;    }    public void setBooks(HashMap<Integer, Book> map) {        this.mapProperty = map;    }}

然后使用此类作为您的返回值

WebMethod

@WebMethod(operationName="getBookList")    public Response getBookList()    {         HashMap<Integer, Book> books = new HashMap<Integer,Book>();         Book b1 = new Book(1,"title1");         Book b2 = new Book(2, "title2");         books.put(1, b1);         books.put(2, b2);         Response resp = new Response();         resp.setBooks(books);         return resp;    }

毕竟，您需要实现您的适配器

MapAdapter
