Java Question

Serialize Java List to XML using Jackson XML mapper

Hi I need to create an XML from JAVA using Jackson-dataformat XMLMapper.
The XML should be like

<Customer>
<id>1</id>
<name>Mighty Pulpo</name>
<addresses>
<city>austin</city>
<state>TX</state>
</addresses>
<addresses>
<city>Hong Kong</city>
<state>Hong Kong</state>
</addresses>
</Customer>


But I get it always like with an extra "< addresses> < /addresses>" tag.

<Customer>
<id>1</id>
<name>Mighty Pulpo</name>
<addresses>
<addresses>
<city>austin</city>
<state>TX</state>
</addresses>
<addresses>
<city>Hong Kong</city>
<state>Hong Kong</state>
</addresses>
<addresses>
</Customer>


I am using below code to create XML

JaxbAnnotationModule jaxbAnnotationModule = new JaxbAnnotationModule();
XmlMapper mapper = new XmlMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
mapper.registerModule(jaxbAnnotationModule);
mapper.registerModule(new GuavaModule());
String xml = mapper.writeValueAsString(customer);
System.out.println(xml);


Please can some one help me? How can I remove the extra tag please. I have tried to use @XmlElement but it does not help help. TIA!!

Answer

Try the below code

@JacksonXmlRootElement(localName = "customer") 
class Customer {

    @JacksonXmlProperty(localName = "id")
    private int id;
    @JacksonXmlProperty(localName = "name")
    private String  name;

    @JacksonXmlProperty(localName = "addresses")
    @JacksonXmlElementWrapper(useWrapping = false)
    private Address[] address;

    //getters, setters, toString
}

class Address {

    @JacksonXmlProperty(localName = "city")
    private String city;

    @JacksonXmlProperty(localName = "state")
    private String state;
    // getter/setter 
}
