我有一个@WebMethod 调用

I have a @WebMethod call

推荐答案

我有类似的需求，从 SoapUI 我注意到我得到了

I had a similar requirement, and from SoapUI I noticed I was getting

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
     xmlns:bus="http://business.test.com/">
  <soapenv:Header/>
  <soapenv:Body>
     <!-- optional -->
     <bus:addItem>
        <bus:item>
           <id>?</id>
           <!-- optional -->
           <name>?</name>
        </bus:item>
        <!-- optional -->
        <itemType>?</itemType>
     </bus:addItem>
  </soapenv:Body>
</soapenv:Envelope>

而不是

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
     xmlns:bus="http://business.test.com/">
  <soapenv:Header/>
  <soapenv:Body>
     <bus:addItem>
        <bus:item>
           <id>?</id>
           <name>?</name>
        </bus:item>
        <itemType>?</itemType>
     </bus:addItem>
  </soapenv:Body>
</soapenv:Envelope>

JAX-WS Metro 2.0 RI 中的一个出路是用

A way out in JAX-WS Metro 2.0 RI is to annotate each parameter with

@XmlElement( required = true )

就我而言，我必须对所需的 WebMethod 参数和所有所需自定义类型的 getter 执行此操作，如下所示:

In my case, I had to do this to required WebMethod parameters and getters of all my required custom types, like so:

...
 @WebMethod( operationName = "getItems" )
   @WebResult( name = "item" )
   public List<Item> getItems(
     @WebParam( name = "itemType" ) @XmlElement( required = true ) String itemType );
...

在我的 POJO 类中:

@XmlAccessorType(XmlAccessType.FIELD)
public class Item implements Serializable
{
   private static final long serialVersionUID = 1L;

   @XmlElement( required = true )
   private int               id;

   @XmlElement( required = true )
   private String            name;

   /**
    * Default constructor.
    */
   public Item() { }

   /**
    * @return the id
    *
    */       
   public int getId()
   {
      return id;
   }

   /* setter for id */

   /**
    * @return the name
    */
   public String getName()
   {
      return name;
   }

   /* setter for name */

}
