Question

我如何使用杰克逊：

    public class XmlJacksonParser {

    URL url;
    public void test() throws IOException {
        try {
            url  = new URL("https://www.onliner.by/feed");
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }
        JacksonXmlModule module = new JacksonXmlModule();
        module.setDefaultUseWrapper(false);
        XmlMapper xmlMapper = new XmlMapper(module);

        OpenCredentials openCredentials = xmlMapper.readValue(url, OpenCredentials.class);
        xmlMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

        Log.e("LogTas", "getItemsSize: " + openCredentials.getCredentials().toString());
        System.out.println(openCredentials);
    }
    @JacksonXmlRootElement(localName = "channel")
    class OpenCredentials {

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

        public Credentials[] getCredentials() {
            return credentials;
        }

        public void setCredentials(Credentials[] credentials) {
            this.credentials = credentials;
        }

        //getters, setters, toString
    }


    class Credentials {

        @JacksonXmlProperty(isAttribute = true)
        private String priv;

        @JacksonXmlProperty(isAttribute = true)
        private String type;

        private String user;

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

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

    }
}

并致电

 XmlJacksonParser s = new XmlJacksonParser();
    try {
        s.test();
    } catch (IOException e) {
        e.printStackTrace();
    }
