Unmarshall xml文件，UnrecognizedPropertyException：无法识别的字段“”

Question

I was wondering if somebody can help me out. I created a small maven project so you can easily run the test. For testing you can run the JUnit test UnmarshalTest.unmarshalResponse() which fails with a exception.

I'm trying to read a value from a xml element with an attribute but somehow I'm not able to to that. Any idea why?

XML looks like:

<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
    <id_lang xlink:href="http://prestashop.local/api/languages/1">57</id_lang>
</prestashop>

Thx a lot

Answer 1

The full message coming back is such as:

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "" (class com.smooth.systems.test.TagValue), not marked as ignorable (2 known properties: "idLang", "href"])
 at [Source: (File); line: 3, column: 76] (through reference chain: com.smooth.systems.test.TestWrapper["id_lang"]->com.smooth.systems.test.TagValue[""])

Which points to the 76 in the body of the <id_lang> element in the example above - hence the missing field name.

(It is line 3, there's another <?xml ... ?> declaration line not seen in the sample xml).

Switching the @XmlValue annotation to @JacksonXmlText on the owning TagValue class seems to work better.
