JAX-WS:如何使SOAP响应返回一个HashMap对象
所以我有一个简单的Web服务:
So I have a simple web service:
@WebMethod(operationName="getBookList")
public HashMap<Integer,Book> 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);
return books;
}
这本书类也是简单的:
The book class is also simple:
public class Book
{
private int id;
private String title;
public int getId()
{
return id;
}
public String getTitle()
{
return title;
}
public Book(int id, String title)
{
id = this.id;
title = this.title;
}
}
现在,当你在浏览器的测试仪调用这个Web服务,我得到:
Now when you call this web service in browser's tester, I get:
Method returned
my.ws.HashMap : "my.ws.HashMap@1f3cf5b"
SOAP Request
...
...
SOAP Response
<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:getBookListResponse xmlns:ns2="http://ws.my/">
<return/>
</ns2:getBookListResponse>
</S:Body>
</S:Envelope>
是否有可能有返回的的HashMap 的所示对象&LT;返回&GT;
标签,像
Is it possible to have the returned HashMap object shown in <return>
tag, something like
<return>
<Book1>
id=1
title=title1
</Book1>
</return>
<return>
<Book2>
id=2
title=title2
</Book2>
</return>
为什么我要在返回变量值的原因是因为,从客户端,我使用jQuery的AJAX在网页中调用这个Web服务,而响应XML我得到的只是一句&LT;返回&GT;
标签。我如何以往任何时候都得到AJAX客户端真正的账面价值?
The reason why I want the values in return tags is because, from client side, I am using jQuery AJAX in a web page to call this web service, and the response XML I am getting is just empty <return>
tags. How do I ever get the real book value from AJAX client side?
下面是我的AJAX的web code:
Here's my AJAX web code:
$.ajax({
url: myUrl, //the web service url
type: "POST",
dataType: "xml",
data: soapMessage, //the soap message.
complete: showMe,contentType: "text/xml; charset=\"utf-8\""
});
function showMe(xmlHttpRequest, status)
{ (xmlHttpRequest.responseXML).find('return').each(function()
{ // do something
}
}
我测试了简单的Hello World Web服务和它的工作。
I tested with simple hello world web service and it worked.
为了帮助JAXB,您可以包你的的HashMap
中的一类,并使用 @XmlJavaTypeAdapter 来使地图以XML的自定义序列化。
In order to help JAXB, you can 'wrap' your HashMap
in a class and use the @XmlJavaTypeAdapter
to make your custom serialization of the map to XML.
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;
}
}
然后使用这个类作为一个返回值的的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,你需要实现您的适配器 MapAdapter
。有几种方法可以做到这一点,所以我建议你检查this
After all, you need to implement your adapter MapAdapter
. There is several ways to do this, so I recommend you to check this
