If we return collection object in the REST response, then the JSON (it will have the root element node as the collections object name - employees in this case) will be in the following format:
{
"employees": [{
"id": "1",
"name": "employee name1",
"company": "ABC Company"
}, {
"id": "2",
"name": "employee name2",
"company": "XYZ Company"
}]
}
Here is a snipper for our JsonProvider config in application context
<bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
<property name="dropRootElement" value="true" />
<property name="serializeAsArray" value="true" />
<property name="dropCollectionWrapperElement" value="true" />
</bean>
@XmlRootElement(name="emps")
public class EmpList{
private List<Emp> employees;
//setter and getter methods
}
@XmlRootElement(name="emp")
public class Emp{
private int id;
private Sting name;
private String company;
//setter and getter methods
}
I don't want the Collection object root element node in the JSON response. Output should be in the following format. I am using Apache CXF framework for rest services.
{
[{
"id": "1",
"name": "employee name1",
"company": "ABC Company"
}, {
"id": "2",
"name": "employee name2",
"company": "XYZ Company"
}]
}
We are using the default cxf JsonProvider (Jettison)
Please suggest any solution. Thanks in advance.
You can configure using droproot element property by customizing the provider
<jaxrs:providers>
<bean class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
<property name="dropRootElement" value="true" />
</bean>
</jaxrs:providers>
You can also configure using custom JAXBElement please check here
Example
<bean id="jaxbProvider" class="org.apache.cxf.jaxrs.provider.JAXBElementProvider">
<property name="outDropElements">
<list>
<!-- ignore drop and {http://numbers}number elements -->
<value>{http://numbers}number</value>
<value>index</value>
</list>
</property>
</bean>
