CXF's JsonProvider not displaying subclass element

Solution Verified - Updated -

Issue

  • We are using default JSONProvider from JBoss Fuse 6.2.1 for our rest API to construct our the JSON output. However, the output format is unexpected.
    • It automatically convert a String to int (e.g. Expected: {"terminal":"1"}. The actual output: {"terminal":1})
    • It simply output the parameters from base class, and ignore the content from subclass. E.g.
class Base {
    String terminal;
    //get & set...
}
class Sub extends Base {
    String otherInfo;
    //get & set...
}

Base b = new Sub();
b.setTerminal("1");
(Sub(b)).setOtherInfo("abc");

The expected output will be {"terminal":"1", "otherInfo":"abc"}.
While the actual output is {"terminal":1}.

  • The configuration in Blueprint file is as following:

    <bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
    <property name="dropRootElement" value="true"></property>
    <property name="supportUnwrapped" value="true"></property>
    <property name="ignoreNamespaces" value="true"></property>
    </bean>
