Java對象到xml模式的自定義映射-Web服務

Question

我在JAX-WS中有一個Web服務，在pom.xml中的maven目標（'ws-jwsc'）生成了WSDL文件以及輸入和輸出XSD。

我想以不同的方式將Java類的屬性映射到WSDL / XSD模式，如下所示：

我有兩個班級1）客戶2）位置

1.客戶-客戶特定信息

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Customer {

   public Customer() {
      super();
   }

   public Customer(CustomerType customerType) {
      this.customerType = customerType;
   }

   public enum CustomerType {
      B, S, C
   }

   private CustomerType customerType;

   private String name;

   private Long accountNumber;

   private Location location;

   // getter/setter for properties

}

2.位置-包含addr1 / addr2 / city / state / zip / country的位置對象

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Location {

   private String address1;

   private String address2;

   private String city;

   private String state;

   private String zip;

   private String country;

   /**
    * @return the city
    */`enter code here`
   public String getCity() {
      return city;
   }

 //getter/setter for properties

}

現在我的問題是在運行時，Customer類中的“ customerType”屬性可以有3個值('B','C','S')

所以，
例如，如果customerType的運行時值為“ S”。

然后代碼'ShipperAddress1', 'ShipperAddress2', 'ShipperCity', 'ShipperState', 'ShipperZip', 'ShipperCountry' for 'address1' , 'address2', 'city', 'state', 'zip' and 'country' SOAP響應XML中分別具有'ShipperAddress1', 'ShipperAddress2', 'ShipperCity', 'ShipperState', 'ShipperZip', 'ShipperCountry' for 'address1' , 'address2', 'city', 'state', 'zip' and 'country'屬性。

示例2：如果customerType的運行時值為“ C”。

那么代碼'ConsigneeAddress1', 'ConsigneeAddress2', 'ConsigneeCity', 'ConsigneeState', 'ConsigneeZip', 'ConsigneeCountry' for 'address1' , 'address2', 'city', 'state', 'zip' and 'country' SOAP響應XML中分別具有'ConsigneeAddress1', 'ConsigneeAddress2', 'ConsigneeCity', 'ConsigneeState', 'ConsigneeZip', 'ConsigneeCountry' for 'address1' , 'address2', 'city', 'state', 'zip' and 'country'屬性。

我需要知道是否可以這樣做，如果可以，怎么辦？ 非常感謝所有幫助。

Answer 1

您可以很好地做到這一點，使用@XmlElementRef ，然后使用“位置繼承”。

為Location或AbstractLocation創建一個基類，然后為Customer Type托運人或收貨人“創建” Location的實例，並覆蓋子類中的元素名稱。 我在下面有一個示例來說明我在哪里顯示一個字段Address1 。 您可以類似地覆蓋所有必填字段。

請注意，我沒有設置Field訪問類型，而是將其設置為Property以便我們僅覆蓋方法，並且字段在基類中保持"private" 。 如果您認為可以protected.字段，也可以進行調整protected. 。

例

在示例中，我只使用了LocationC和LocationS 。 您可以添加LocationB 。

具有主類的Customer.java。 注意@XmlElementRef（name =“ Location”）

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElementRef;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Customer {

    public CustomerType getCustomerType() {
        return customerType;
    }

    public void setCustomerType(CustomerType customerType) {
        this.customerType = customerType;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Long getAccountNumber() {
        return accountNumber;
    }

    public void setAccountNumber(Long accountNumber) {
        this.accountNumber = accountNumber;
    }

    public GeneralLocation getLocation() {
        return location;
    }

    public void setLocation(GeneralLocation location) {
        this.location = location;
    }

    public Customer() {
        super();
    }

    public Customer(CustomerType customerType) {
        this.customerType = customerType;
    }

    public enum CustomerType {
        B, S, C
    }

    private CustomerType customerType;

    private String name;

    private Long accountNumber;

    @XmlElementRef(name = "Location")
    private GeneralLocation location;

    public static void main(String[] args) throws Exception {
        Customer c = new Customer();
        c.setAccountNumber(1111111l);
        c.setCustomerType(CustomerType.C);
        LocationC loc = new LocationC();
        loc.setAddress1("I am address 1");
        c.setLocation(loc);

        Customer c2 = new Customer();
        c2.setAccountNumber(222222l);
        c.setCustomerType(CustomerType.S);
        LocationS locs = new LocationS();
        locs.setAddress1("I am S address 1");
        c2.setLocation(locs);
        JAXBContext jc = JAXBContext.newInstance(Customer.class);
        Marshaller marrshaller = jc.createMarshaller();
        marrshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);

        marrshaller.marshal(c, System.out);
        marrshaller.marshal(c2, System.out);
    }

}

Base AbstractLocation.java（我已經使用注釋@XmlTransient隱藏了它的屬性。

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.bind.annotation.XmlTransient;


@XmlRootElement
@XmlAccessorType(XmlAccessType.PROPERTY)
@XmlSeeAlso({LocationC.class, LocationS.class})
abstract class GeneralLocation {

   private String address1;

   private String address2;

   private String city;

   private String state;

   private String zip;

   private String country;

   @XmlTransient()
    public String getAddress1() {
        return address1;
    }

    public void setAddress1(String address1) {
        this.address1 = address1;
    }

    public String getAddress2() {
        return address2;
    }

    public void setAddress2(String address2) {
        this.address2 = address2;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }

    public String getZip() {
        return zip;
    }

    public void setZip(String zip) {
        this.zip = zip;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }
}

LocationC.java

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement()
public class LocationC extends GeneralLocation {

    @XmlElement(name="ConsigneeAddress1")
    @Override
    public String getAddress1() {
        return super.getAddress1();
    }
}

LocationS.java

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement()
@XmlAccessorType(XmlAccessType.PROPERTY)
public class LocationS  extends GeneralLocation {

    @XmlElement(name="ShipperAddress1")
    public String getAddress1() {
        return super.getAddress1();
    }
}
