spring-mvc中返回fastjson的json数据去掉null值

如下配置

<property name="serializationInclusion">
<value type="com.fasterxml.jackson.annotation.JsonInclude.Include">NON_NULL</value>
</property>

以下为我的部分配置属性。

    <bean
        class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
        <property
            name="ignoreAcceptHeader"
            value="false" />
        <property name="mediaTypes">
            <map>
                <entry
                    key="json"
                    value="application/json;charset=UTF-8" />
            </map>
        </property>
        <property name="defaultViews">
            <list>
                <bean
                    class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">
                    <property name="objectMapper">
                        <bean
                            class="com.fasterxml.jackson.databind.ObjectMapper">
                            <property name="serializationInclusion">
                                <value
                                    type="com.fasterxml.jackson.annotation.JsonInclude.Include">NON_NULL</value>
                            </property>
                            <property name="dateFormat">
                                <bean class="java.text.SimpleDateFormat">
                                    <constructor-arg

                                </bean>
                            </property>
                        </bean>
                    </property>
                    <property
                        name="extractValueFromSingleKeyModel"
                        value="false" />
                </bean>
