以下代码导致强制转换异常,我不确定原因。 ParameterValueList中的对象应该热切地解组为JAXB对象ParameterValueStruct,但事实并非如此。一切都是直接从soap编码和cwmp架构文件生成的。
有人有任何建议吗?
public static void main(String[] args) throws JAXBException, FileNotFoundException
{
JAXBContext c = JAXBContext.newInstance("org.dslforum.cwmp_1_1");
Unmarshaller u = c.createUnmarshaller();
Inform inform = (Inform) u.unmarshal(new FileInputStream("test.xml"));
List<Object> list = inform.getParameterList().getAny();
System.out.println(list); // prints [[ParameterValueStruct: null], ...
for (Object o : list) {
ParameterValueStruct pv = (ParameterValueStruct)o; // exception here
System.out.println(pv.getName());
}
}
线程“main”中的异常java.lang.ClassCastException:com.sun.org.apache.xerces.internal.dom.ElementNSImpl无法强制转换为org.dslforum.cwmp_1_1.ParameterValueStruct 在Test.main(Test.java:26)
我有这个类是使用Java的xjc工具从http://schemas.xmlsoap.org/soap/encoding/生成的:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Array", propOrder = {
"any"
})
@XmlSeeAlso({
ParameterValueList.class,
})
public class Array {
@XmlAnyElement(lax = true)
protected List<Object> any;
@XmlAttribute(name = "id")
@XmlJavaTypeAdapter(CollapsedStringAdapter.class)
@XmlID
@XmlSchemaType(name = "ID")
protected java.lang.String id;
@XmlAttribute(name = "href")
@XmlSchemaType(name = "anyURI")
protected java.lang.String href;
@XmlAttribute(name = "arrayType", namespace = "http://schemas.xmlsoap.org/soap/encoding/")
protected java.lang.String arrayType;
@XmlAttribute(name = "offset", namespace = "http://schemas.xmlsoap.org/soap/encoding/")
protected java.lang.String offset;
@XmlAnyAttribute
private Map<QName, java.lang.String> otherAttributes = new HashMap<QName, java.lang.String>();
public List<Object> getAny() {
if (any == null) {
any = new ArrayList<Object>();
}
return this.any;
}
....
}
我也有这两个类也是通过相同的工具生成的,但来自https://www.broadband-forum.org/cwmp/cwmp-1-1.xsd:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "ParameterValueList")
public class ParameterValueList
extends Array
{
}
第二档:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "ParameterValueStruct", propOrder = {
"name",
"value"
})
public class ParameterValueStruct {
@XmlElement(name = "Name", required = true)
protected String name;
@XmlElement(name = "Value", required = true)
@XmlSchemaType(name = "anySimpleType")
protected Object value;
...
}
这是我的test.xml文件:
<?xml version="1.0"?>
<cwmp:Inform xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:cwmp="urn:dslforum-org:cwmp-1-1" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ParameterList soap-enc:arrayType="cwmp:ParameterValueStruct[3]">
<ParameterValueStruct>
<Name>Device.DHCPv4.ClientNumberOfEntries</Name>
<Value xsi:type="xsd:unsignedInt">0</Value>
</ParameterValueStruct>
<ParameterValueStruct>
<Name>Device.DNS.Client.ServerNumberOfEntries</Name>
<Value xsi:type="xsd:unsignedInt">1</Value>
</ParameterValueStruct>
<ParameterValueStruct>
<Name>Device.DeviceInfo.AdditionalSoftwareVersion</Name>
<Value xsi:type="xsd:string">DM: 532,SK: 2.6.33.9-rt31,SF: 251X 137.0,BK: 10</Value>
</ParameterValueStruct>
</ParameterList>
</cwmp:Inform>
答案 0 :(得分:1)
您只需在@XmlRootElement(name="ParameterValueStruct",namespace="")
ParameterValueStruct
即可
您需要namespace=""
package-info.java
@javax.xml.bind.annotation.XmlSchema(namespace = "urn:dslforum-org:cwmp-1-1")
package org.dslforum.cwmp_1_1;
T 他正确的课程应如下所示:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "ParameterValueStruct", propOrder = {
"name",
"value"
})
@XmlRootElement(name="ParameterValueStruct",namespace="")
public class ParameterValueStruct {
@XmlElement(name = "Name", required = true)
protected String name;
@XmlElement(name = "Value", required = true)
@XmlSchemaType(name = "anySimpleType")
protected Object value;
...
}
PS:有关@XmlAnyElement(lax=true)
