Question

使用Moxy将JSON字符串转换为XML对象时遇到问题。以下是我进行此转换时获得的例外情况：

Exception [EclipseLink-43] (Eclipse Persistence Services - 2.6.2.v20151217-774c696): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: Missing class for indicator field value [TENANT] of type [class java.lang.String].
Descriptor: XMLDescriptor(fr.niji.nates.webservices.macd.ws.COMPONENTTYPE --> [])
    at org.eclipse.persistence.exceptions.DescriptorException.missingClassForIndicatorFieldValue(DescriptorException.java:940)
    at org.eclipse.persistence.internal.oxm.QNameInheritancePolicy.classFromRow(QNameInheritancePolicy.java:278)
[...]

这是COMPONENTTYPE类：

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.bind.annotation.XmlType;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "COMPONENT_TYPE")
@XmlSeeAlso({
    COMPONENTDETAILTYPE.class,
    MACDRESULTTYPE.Created.class
})
public class COMPONENTTYPE {

    @XmlAttribute(name = "type", required = true)
    protected String type;
    @XmlAttribute(name = "dbid", required = true)
    protected int dbid;

    public String getType() {
        return type;
    }

    public void setType(String value) {
        this.type = value;
    }

    public int getDbid() {
        return dbid;
    }

    public void setDbid(int value) {
        this.dbid = value;
    }
}

问题似乎只出现在＆＃34;类型＆＃34;属性。

有没有人有想法？谢谢，

我找到的解决方案是将注释@XmlDiscriminatorNode添加到类中：

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.bind.annotation.XmlType;

import org.eclipse.persistence.oxm.annotations.XmlDiscriminatorNode;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "COMPONENT_TYPE")
@XmlSeeAlso({
    COMPONENTDETAILTYPE.class,
    fr.niji.nates.webservices.macd.ws.MACDRESULTTYPE.Created.class
})
@XmlDiscriminatorNode("@@type")
public class COMPONENTTYPE {
    [...]

EclipseLink：＆＃34;缺少指标字段值的类＆＃34;没有继承
