我的 Pojo 类中有一对多映射。
一家店有一家分店，一个分店有很多家店铺
这是商店代码：
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name="Shop")
public class Shop {
@XmlID
private String name;
@XmlIDREF
@XmlElement(name="ShopBranch",type=Branch.class)
private Branch branch;
//Getter Setter
}
以下是分行代码：
@XmlAccessorType(XmlAccessType.FIELD)
public class Branch {
@XmlID
private String name;
private String address;
@XmlIDREF
@XmlElement(nillable=false,required=true)
private List<Shop> shops;
//Getter and Setters
}
我正在发布一个带有一些基本方法的网络服务。我的 wsimport 正在生成 Branch 类，如下所示
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "branch", propOrder = {
"branchName",
"address",
"branchShop"
})
public class Branch {
@XmlElement(name = "BranchName")
@XmlJavaTypeAdapter(CollapsedStringAdapter.class)
@XmlID
@XmlSchemaType(name = "ID")
protected String branchName;
protected String address;
@XmlElementRef(name = "BranchShop", type = JAXBElement.class)
protected List<JAXBElement<Object>> branchShop;
//Getter-Setter
}
我不知道为什么它是 List> 而不是 List>。但不管怎么说。我有一个返回所有分支的方法，并且工作正常。当我从分支的实例中提取branchShop时，我得到了branchShop列表的正确大小，但对于列表中的所有项目，getValue返回NULL。
下面是简短的代码：
PencilCatalog service= new PencilCatalog();
com.pencilhouse.webservices.PencilService port=service.getPencilCatalogPort();
((BindingProvider)port).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, Constant.PENCIL_SERVICE);
List<Branch> branches= port.getAllBranches();
for(Branch b:branches)
{
System.out.println("******************Branch:"+b.getBranchName()+" "+b.getAddress()+"******************");
JAXBElement<Object>o=b.getBranchShop().get(0);
System.out.println(o+"Value"+o.getScope()+" "+o.getValue());
}
o/p

生成的 WSDL 相当大。我只发布分支机构和商店类型。我正在使用 Endpoint 发布 Web 服务
生成的 XML：
<xs:complexType name="shop">
<xs:sequence>
<xs:element name="name" type="xs:ID" minOccurs="0"/>
<xs:element name="ShopBranch" type="xs:IDREF" minOccurs="0"/>

<xs:complexType name="branch">
