JAX-WS Exception - "return is not a valid property"
提问by philomatic
I am new to JAX-WS, when I try to start this simple Web Service:
我是 JAX-WS 的新手，当我尝试启动这个简单的 Web 服务时：
Interface:
界面：
package ws;
import java.util.HashMap;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public interface IBasket {
@WebMethod public abstract void addItem(int productId, int count);
@WebMethod public abstract HashMap<Integer, Integer> getBasketMap();
}
Implementing Class:
实现类：
package model;
import java.util.HashMap;
import javax.jws.WebService;
import ws.IBasket;
@WebService(endpointInterface = "ws.IBasket")
public class Basket implements IBasket {
private HashMap<Integer, Integer> basket;
public Basket() {
this.basket = new HashMap<Integer, Integer>();
}
@Override
public void addItem(int productId, int count) {
int currentCount = 0;
if (basket.containsKey(productId)) {
currentCount = basket.get(productId);
}
basket.put(productId, currentCount + count);
}
@Override
public HashMap<Integer, Integer> getBasketMap() {
return basket;
}
}
Publisher:
出版商：
package endpoint;
import javax.xml.ws.Endpoint;
import model.Basket;
public class WSPublisher {
public static void main(String[] args) {
Endpoint.publish("http://localhost:8080/WS/Basket",new Basket());
}
}
I'm getting the following stacktrace:
我得到以下堆栈跟踪：

Ok, I've the solution for this Problem, see:
好的，我有这个问题的解决方案，请参阅：
How can I pass in an array as a value into a PHP soapclient request?
如何将数组作为值传递给 PHP soapclient 请求？
Its the same for HashMap return values. JAXB can't handle HashMaps as parameters/return values, maybe because they're generic.
HashMap 返回值也是如此。JAXB 无法将 HashMap 作为参数/返回值处理，可能是因为它们是通用的。
So instead, we need a wrapper class for the HashMap
所以相反，我们需要一个 HashMap 的包装类
public class HashMapWrapper {
private HashMap<Integer, Integer> basketMap;
public HashMapWrapper(HashMap<Integer, Integer> basketMap) {
this.setBasketMap(basketMap);
}
and use this one as return value.
并将其用作返回值。

Are you using Metro as your JAX-WS provider? If so try setting the Document style as follows to RPC. This annotation should come after the @WebService annotation.;
您是否使用 Metro 作为您的 JAX-WS 提供程序？如果是这样，请尝试将文档样式设置为 RPC。这个注释应该在@WebService 注释之后。
@SOAPBinding(style = Style.RPC)
