jaxb：將屬性綁定到元素

如何使用JAXB實現此XML？目前grantA，C，B元素中的expires屬性不受限制 - 但它應該是。我不知道如何將元素與屬性關聯。我是否必須爲每個授權A，C，B創建類？

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
    <customers> 
     <customer> 
      <name>C1</name> 
      <grantA expires="">false</grantA>

我現在的狀態是：

Customers.java：

@XmlRootElement(name = "customers") 
public class Customers 
{ 
    private List<Customer> customerList; 

    @XmlElement(name = "customer") 
    public List<Customer> getCustomerList() 
    { 
     if (null == customerList) 
     { 
      customerList = new ArrayList<Customer>(); 
     } 
     return customerList; 
    } 

    public void setCustomerList(List<Customer> customers) 
    { 
     this.customerList = customers; 
    } 

}

Customer.java

@XmlRootElement(name = "customer") 
@XmlType(propOrder = { "name", "grantA", "grantB", "grantC" }) 
public class Customer 
{ 
    private String name = ""; 
    private boolean grantA; 
    private boolean grantB; 
    private boolean grantC; 

    @XmlJavaTypeAdapter(CollapsedStringAdapter.class) 
    @XmlElement(name = "name", required=true) 
    public String getName() 
    { 
     return name; 
    } 

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

    @XmlElement(name = "grantA", required=true) 
    public boolean isGrantA() 
    { 
     return grantA; 
    } 

    public void setGrantA(boolean grantA) 
    { 
     this.grantA = grantA; 
    } 



    @XmlElement(name = "grantB", required=true) 
    public boolean isGrantB() 
    { 
     return grantB; 
    } 

    public void setGrantB(boolean grantB) 
    { 
     this.grantB = grantB; 
    } 

    @XmlElement(name = "grantC", required=true) 
    public boolean isGrantC() 
    { 
     return grantC; 
    } 

    public void setGrantC(boolean grantC) 
    { 
     this.grantC = grantC; 
    } 


    @Override 
    public String toString() 
    { 
     return "" + name + "[ " + grantA + ", " + grantB + " " + grantC + " ]"; 
    } 

}

您可以創建一個類，Grant，像這樣：

@XmlType 
public class Grant { 
    @XmlAttribute 
    private String expires; 

    @XmlValue 
    private boolean value; 

    //getters and setters 
}

，並在Customer類映射它以不同的名稱，例如：

public class Customer 
{ 
    private String name = ""; 
    @XmlElement(name="grantA"); 
    private Grant grantA; 

    @XmlElement(name="grantB"); 
    private Grant grantB; 

    @XmlElement(name="grantC"); 
    private Grant grantC; 

    //rest of the code 
}

您可以使用一個類來表示具有expires屬性的布爾值。 XmlValue註釋用於表示其中一個屬性作爲元素的內容，而另一個屬性可註釋爲XmlAttribute。

@XmlType 
class BooleanWithExpires { 
    @XmlValue public boolean value; 
    @XmlAttribute public String expires; 
}

然後你可以使用這種類型的，而不是針對boolean不同批成員。無論您是想使用此類將數據存儲在您的Customer對象中，還是以其他方式存儲信息並僅在內部存儲器和BooleanWithExpires之間在XML子元素的獲取器和設置器中進行轉換。

如果更符合您的編碼風格，可以隨意將代碼從公共成員更改爲getter和setter。此外，請確保使用最適合expires的任何類型，例如XMLGregorianCalendar。如果這適合您，您可能還需要根據需要表示expires屬性。
