无法使用 Jackson 反序列化 XML 中的非格式化子节点

Question

I am converting Xml to Pojo object with help of jackson, But due to different format of xml it's not converting all fields to Pojo, Please follow for xml structure and mapping Pojo,

Here I want to deserialize 13 value of iphone.

XML- <PhoneDetails> <Iphone os="ios">13</Iphone> </PhoneDetails>

POJO

@lombok.Data 
public class PhoneDetails { 
    @JacksonXmlProperty(localName = "Iphone") 
    private Iphone iphoneDetails; 
}

@lombok.Data 
public class Iphone { 
    private String os; 
    private String iphone; 
}

main method

public class Demo { 
    public static void main(String[] args) throws Exception { 
        XmlMapper xmlMapper = new XmlMapper();      
        xmlMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); 
        xmlMapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, true);
        xmlMapper.configure(MapperFeature.USE_WRAPPER_NAME_AS_PROPERTY_NAME, false); 
        File availsContract = ResourceUtils.getFile("classpath:to_deserialize.xml");

        String content = new String(Files.readAllBytes(availsContract.toPath()));
        PhoneDetails productDetail = xmlMapper.readValue(content, PhoneDetails.class);
        System.out.println("Product Details :" + productDetail);
    }

}

Please reply with solutions.

Welcome to Stack Overflow, a simple xmlMapper mapper is enough to deserialize your xml; you have to use the JacksonXmlText annotation to deserialize the 13 value from the <PhoneDetails> <Iphone os="ios">13</Iphone> </PhoneDetails> xml file into your String iphone property:

@Data
public class PhoneDetails { 
   
    @JacksonXmlProperty(localName = "Iphone") 
    private Iphone iphoneDetails; 
}

@Data
public class Iphone {

    private String os;
    @JacksonXmlText
    private String iphone;
}

//Input xmlfile:
//<PhoneDetails> <Iphone os="ios">13</Iphone> </PhoneDetails>
XmlMapper xmlMapper = new XmlMapper();
PhoneDetails phoneDetails = xmlMapper.readValue(xml, PhoneDetails.class);
//ok, it prints PhoneDetails(iphoneDetails=Iphone(os=ios, iphone=13))
System.out.print(phoneDetails);
