Question

我使用Sprint 3.0.5和附带的jaxb marshaller与REST服务进行通信。由不同公司提供的服务通过POST向我的服务发送XML，我必须在我的Java对象中解组该XML并处理它们。

我遇到的问题是，XML标签以大写字母开头（它们不会改变），因此JAXB marshaller无法解组该对象。

XML如下所示：

<Ssm_Packet>
<Version>1</Version>
<Protocol_ID>0</Protocol_ID>
<Packet_Id>{84ca597c-05e2-4357-897c-892f428c35ce}</Packet_Id>
<Priority>0</Priority>
<Source_Address>1:11111111111111</Source_Address>
<Destination_Address>2:LA3222222222222</Destination_Address>
<Body>Some TExt</Body>
<Billing />
</Ssm_Packet>

我为jaxb定义的bean如下所示：

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


@XmlRootElement(name="Ssm_Packet")
public class Ssm_Packet {
@XmlElement(name="Version")
private String version;
private String protocol_ID;
private String packet_Id;
private String priority;
private String source_Address;
private String destination_Address;
private String body;
private String billing;
/**
 * @return the version
 */
public String getVers() {
    return version;
}
/**
 * @param version the version to set
 */
public void setVers(String Version) {
    this.version = Version;
}
/**
 * @return the protocol_ID
 */
public String getProtocol_ID() {
    return protocol_ID;
}
/**
 * @param protocol_ID the protocol_ID to set
 */
public void setProtocol_ID(String Protocol_ID) {
    this.protocol_ID = Protocol_ID;
}
/**
 * @return the packet_Id
 */
public String getPacket_Id() {
    return packet_Id;
}
/**
 * @param packet_Id the packet_Id to set
 */
public void setPacket_Id(String Packet_Id) {
    this.packet_Id = Packet_Id;
}
/**
 * @return the priority
 */
public String getPriority() {
    return priority;
}
/**
 * @param priority the priority to set
 */
public void setPriority(String Priority) {
    this.priority = Priority;
}
/**
 * @return the source_Address
 */
public String getSource_Address() {
    return source_Address;
}
/**
 * @param source_Address the source_Address to set
 */
public void setSource_Address(String Source_Address) {
    this.source_Address = Source_Address;
}
/**
 * @return the destination_Address
 */
public String getDestination_Address() {
    return destination_Address;
}
/**
 * @param destination_Address the destination_Address to set
 */
public void setDestination_Address(String Destination_Address) {
    this.destination_Address = Destination_Address;
}
/**
 * @return the body
 */
public String getBody() {
    return body;
}
/**
 * @param body the body to set
 */
public void setBody(String Body) {
    this.body = Body;
}
/**
 * @return the billing
 */
public String getBilling() {
    return billing;
}
/**
 * @param billing the billing to set
 */
public void setBilling(String Billing) {
    this.billing = Billing;
}
}

现在，如果我让JAXb解组该对象中的XML，除非xml标记没有大写字母，否则他不会填写xml的值。

任何人都可以帮我解决如何将这些值解组到我的bean中吗？

您可以使用@XmlElement注释指定与每个字段/属性对应的元素名称。

/**
 * @return the protocol_ID
 */
@XmlElement(name="Protocol_ID")
public String getProtocol_ID() {
    return protocol_ID;
}

如果您想要对字段进行注释，则需要设置@XmlAccessorType(XmlAccessType.FIELD)：

@XmlRootElement(name="Ssm_Packet")
@XmlAccessorType(XmlAccessType.FIELD)
public class Ssm_Packet {
    @XmlElement(name="Version")
    private String version;
}

EclipseLink JAXB (MOXy)还包含一个扩展，您可以在其中覆盖标准JAXB算法，以将Java字段/属性名称转换为XML名称：

JaxB用大写字母标记解组XML
