How to remove the root node name from the json returned by Spring MVC, mvcjson

How to remove the root node name from the json returned by Spring MVC, mvcjson

The configuration view in spring xml is as follows:

<property name="defaultViews">            <list>                <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">                </bean>            </list>        </property>

The returned result is:

{"commonAjaxResponse":{"code":1,"errorCode":null,"errorMessage":null,"data":{"key":"123"}}}

Here, commonAjaxResponse is not what we want.

Note that the API description of the attribute extractValueFromSingleKeyModel of MappingJackson2JsonView can be set to true.

<property name="defaultViews">            <list>                <bean                    class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">                    <property name="extractValueFromSingleKeyModel" value="true" />                </bean>            </list>        </property>

Solution:

{"code":1,"errorCode":null,"errorMessage":null,"data":{"key":"123"}}
