SpringMVC返回JSON，为空时不返回的配置一直报错

[猫鼠同眠]

SpringMVC配置JSON转换器，如果字段为空，则不输出，配置如下：

<bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
    <property name="supportedMediaTypes">
      <list>
        <value>text/html;charset=UTF-8</value>
      </list>
    </property>
    <property name="objectMapper">
      <bean class="com.fasterxml.jackson.databind.ObjectMapper">
        <!-- 时间格式转换 -->
        <property name="dateFormat">
          <bean class="java.text.SimpleDateFormat">
            <constructor-arg type="java.lang.String" value="yyyy-MM-dd HH:mm:ss"/>
          </bean>
        </property>
        <!-- 为null字段时不转换 -->
        <property name="serializationInclusion">
          <value type="com.fasterxml.jackson.annotation.JsonInclude.Include">NON_NULL</value>
          <!-- <bean class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean">    
            <property name="staticField" value="com.fasterxml.jackson.annotation.JsonInclude.Include.NON_NULL" />    
          </bean> -->
        </property>
      </bean>
    </property>
  </bean>

但是启动时，一直报错，错误如下：
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'serializationInclusion' of bean class [com.fasterxml.jackson.databind.ObjectMapper]: Bean property 'serializationInclusion' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

serializationInclusion 这个不是有问题么？~

[like987654]

在需要序列化为json输出的类上增加 @JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)

这样只能对单个类起作用，如果需要序列化的类多了好麻烦的

现在就是不知道为什么有问题，com.fasterxml.jackson.databind.ObjectMapper类中是有setSerializationInclusion()方法的
