Using Jackson XmlMapper annotations,how would I deserialize this XML into a pojo?

<?xml version="1.0" encoding="UTF-8"?>
<open>
<creds priv="write" type="internal">
<user>Username1</user>
<client_token>abcplaudzrbcy37c</client_token>
<client_secret>0cxDE3LE0000=</client_secret>
</creds>
<creds priv="read" type="internal">
<user>Username1</user>
<client_token>123plaudzrbcy37c</client_token>
<client_secret>0cxDE3LE1234=</client_secret>
</creds>
<creds priv="none" type="internal">
<user>Username1</user>
<client_token>000plaudzrbcy37c</client_token>
<client_secret>0cxDE3LEabcd=</client_secret>
</creds>

</open>

@JacksonXmlRootElement(localName = "open")
class OpenCredentials {

    @JacksonXmlProperty(localName = "creds")
    @JacksonXmlElementWrapper(useWrapping = false)
    private Credentials[] credentials;

    //getters,setters,toString
}


class Credentials {

    @JacksonXmlProperty(isAttribute = true)
    private String priv;

    @JacksonXmlProperty(isAttribute = true)
    private String type;

    private String user;

    @JacksonXmlProperty(localName = "client_token")
    private String clientToken;

    @JacksonXmlProperty(localName = "client_secret")
    private String clientSecret;

    //getters,toString
}

Simple usage:

XmlMapper mapper = new XmlMapper();
File source = new File(xmlPath);
OpenCredentials openCredentials = mapper.readValue(source,OpenCredentials.class);
System.out.println(openCredentials);

Above program prints (for your XML):

OpenCredentials{credentials=[Credentials{priv='write',type='internal',user='Username1',client_token='abcplaudzrbcy37c',client_secret='0cxDE3LE0000='},Credentials{priv='read',client_token='123plaudzrbcy37c',client_secret='0cxDE3LE1234='},Credentials{priv='none',client_token='000plaudzrbcy37c',client_secret='0cxDE3LEabcd='}]}
