JAXB解组错误:预期的元素是< {} Root> [英] JAXB unmarshalling error: Expected elements are <{ } Root>
问题描述
我正在重复使用其他地方生成的现有对象来解组以String类型出现的XML数据。
I'm reusing existing objects generated elsewhere to unmarshall XML data coming in as a String type.
对象:
/* 3: */ import java.util.ArrayList;
/* 4: */ import java.util.List;
/* 5: */ import javax.xml.bind.annotation.XmlAccessType;
/* 6: */ import javax.xml.bind.annotation.XmlAccessorType;
/* 7: */ import javax.xml.bind.annotation.XmlElement;
/* 8: */ import javax.xml.bind.annotation.XmlRootElement;
/* 9: */ import javax.xml.bind.annotation.XmlType;
/* 10: */
/* 11: */ @XmlAccessorType(XmlAccessType.FIELD)
/* 12: */ @XmlType(name="", propOrder={"policy"})
/* 13: */ @XmlRootElement(name="MyNodeResponse")
/* 14: */ public class MyNodeResponse
/* 15: */ {
/* 16: */ @XmlElement(name="Policy")
/* 17: */ protected List<Policy> policy;
/* 18: */
/* 19: */ public List<Policy> getPolicy()
/* 20: */ {
/* 21:65 */ if (this.policy == null) {
/* 22:66 */ this.policy = new ArrayList();
/* 23: */ }
/* 24:68 */ return this.policy;
/* 25: */ }
/* 26: */ }
我的解组代码:
JAXBContext jc = JAXBContext.newInstance(MyNodeResponse.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
MyNodeResponse myNodeResponse = (MyNodeResponse)unmarshaller.unmarshal(new InputSource(new ByteArrayInputStream(xmlStringInput.getBytes("utf-8"))));
我的输入XML:
<ns2:MyNodeResponse
xmlns:ns2="mynamespace/2010/10">
<ns2:Policy>
....more data....
<ns2:Policy/>
<ns2:MyNodeResponse />
解组时出现以下错误:
unexpected element (uri:"mynamespace/2010/10", local:"MyNodeResponse"). Expected elements are <{}MyNodeResponse>
{}在错误中引用了什么,以及如何解组?匹配输入XML中存在的内容以及对象期望的方式?
What exactly does the "{ }" refer to in the error, and how do I unmarshall in a way to match what is present in the input XML and how the object is expecting?
推荐答案
错误消息说的是什么
What the Error Message is Saying
{}在错误中引用了什么?
What exactly does the "{ }" refer to in the error
在 {} MyNodeRespons
{}
部分是指没有名称空间URI的限定名称部分集。
In {}MyNodeRespons
the {}
portion refers to that qualified name not having the namespace URI portion set.
您需要使用包级别<$映射命名空间限定c $ c> @XmlSchema 注释:
You need to map the namespace qualification using the package level @XmlSchema
annotation:
package-info.java
@XmlSchema(
namespace = "mynamespace/2010/10",
elementFormDefault = XmlNsForm.QUALIFIED)
package example;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
