Question

我使用xstream从java对象生成xml，下面是从java对象生成的xml

<brokermail>
  <invoiceReferenceNotificationMessage>
    <com.absfm.ice.ioa.jms.InvoiceReferenceNotificationMessage>
      <InvoiceReference>SM/829709/0315</InvoiceReference>
      <ABSReference>IRMAR157311</ABSReference>
      <Currency>GBP</Currency>
      <InvoiceAmount>2546.0</InvoiceAmount>
      <PaidAmount>1245.0</PaidAmount>
      <BalanceAmount>0.0</BalanceAmount>
      <ValueDate>2015-05-23 20:07:20.78 IST</ValueDate>
      <Remarks>abc</Remarks>
    </com.rbsfm.ice.ioa.jms.InvoiceReferenceNotificationMessage>
    <com.rbsfm.ice.ioa.jms.InvoiceReferenceNotificationMessage>
      <InvoiceReference>SM/15</InvoiceReference>
      <ABSReference>I157311</ABSReference>
      <Currency>EUR</Currency>
      <InvoiceAmount>255546.0</InvoiceAmount>
      <PaidAmount>125545.0</PaidAmount>
      <BalanceAmount>0.0</BalanceAmount>
      <ValueDate>2015-05-23 20:07:20.78 IST</ValueDate>
      <Remarks>abERRc</Remarks>
    </com.absfm.ice.ioa.jms.InvoiceReferenceNotificationMessage>
  </invoiceReferenceNotificationMessage>
</brokermail>

但我希望以下面的方式生成xml

<brokermail>

  <invoiceReferenceNotificationMessage>
   <InvoiceReference>SM/829709/0315</InvoiceReference>
      <ABSReference>IRMAR157311</ABSReference>
      <Currency>GBP</Currency>
      <InvoiceAmount>2546.0</InvoiceAmount>
      <PaidAmount>1245.0</PaidAmount>
      <BalanceAmount>0.0</BalanceAmount>
      <ValueDate>2015-05-23 20:38:35.110 IST</ValueDate>
      <Remarks>abc</Remarks>
     </invoiceReferenceNotificationMessage>

     <invoiceReferenceNotificationMessage>
        <InvoiceReference>SM/15</InvoiceReference>
      <ABSReference>I157311</ABSReference>
      <Currency>EUR</Currency>
      <InvoiceAmount>255546.0</InvoiceAmount>
      <PaidAmount>125545.0</PaidAmount>
      <BalanceAmount>0.0</BalanceAmount>
      <ValueDate>2015-05-23 20:38:35.110 IST</ValueDate>
      <Remarks>abERRc</Remarks>
  </invoiceReferenceNotificationMessage>

</brokermail>

现在正如上面所示，我希望以上述方式生成xml，而这种方式现在还没有发生。你能否告诉我在下面的pojo中需要做些什么改变才能以上述方式获取xml。下面是我的pojo

  public class Mail {

@SuppressWarnings("unused")
private  List<InvoiceReferenceNotificationMessage> invoiceReferenceNotificationMessage;

  @XStreamImplicit(itemFieldName="invoiceReferenceNotificationMessage")
    private  List<InvoiceReferenceNotificationMessage> InvoiceReferenceNotificationMessage = 
new ArrayList<InvoiceReferenceNotificationMessage>();

    public List<InvoiceReferenceNotificationMessage> getInvoiceReferenceNotificationMessages() {
        return InvoiceReferenceNotificationMessage;
    }

    public void addInvoiceReferenceNotificationMessages(List<InvoiceReferenceNotificationMessage> invoiceReferenceNotificationMessages) {
        this.invoiceReferenceNotificationMessage = invoiceReferenceNotificationMessages;
    }

}

这是正在发生的主要方法调用

下面是使用xstream以下生成xml的主要类。

ist<InvoiceReferenceNotificationMessage> invoiceReferenceNotificationMessagest = new ArrayList<InvoiceReferenceNotificationMessage>();
    invoiceReferenceNotificationMessagest.add(invoiceReferenceNotificationMessage);
    invoiceReferenceNotificationMessagest.add(invoiceReferenceNotificationMessage1);

    Mail m = new Mail();
    m.addInvoiceReferenceNotificationMessages(invoiceReferenceNotificationMessagest);




    XStream xstream = new XStream();
    xstream.alias("brokermail", Mail.class);
    xstream.processAnnotations(Mail.class);
    String abc = xstream.toXML(m);
    System.out.println(abc);

现在在xstream.processAnnotations（Mail.class）;代码行我得到恭维问题indiacating添加演员到xsteam请告知如何克服这个

the complation error that i am getting that method processAnnotations(class<Mail>) is undefined for the type Xstream

伙计们请为此提供建议

Answer 1

确保您使用的是最新版本的xstream。 processAnnotations方法在1.3

中引入

如果使用maven，请尝试

<dependency>
    <groupId>com.thoughtworks.xstream</groupId>
    <artifactId>xstream</artifactId>
    <version>1.4.8</version>
</dependency>

xml不是从java中的对象以特定格式生成的
