JAXB ignoring xml tag attribute

问题

I read xml files with JAXB. I have the following structure

<A>
  <B value="some string" />
</A>

I have the following model

@XmlRootElement
class A{
  @XmlElement(name = "B", required = true)
  @XmlPath("B/@value")
  String b;
}

I read the B tags value attribute in my b Instance variable.

But in some XML files i have in the B tag following Structure <#B/> While JAXB unmarshall the files i become exception that the format is not correct. javax.xml.stream.XMLStreamException: ParseError at [row,col]:[19,4]

回答1:

You should just have the following without the @XmlElement annotation:

@XmlRootElement
class A{
  @XmlPath("B/@value")
  String b;
}
