Jackson+Spring3.0.5自定义对象映射器

Question

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list>
            <bean
                class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
                <property name="objectMapper" ref="jacksonObjectMapper" />
            </bean>
        </list>
    </property>
</bean>

<bean id="jacksonObjectMapper" class="ro.softwin.cnfp.ConversionServiceAwareObjectMapper" />

<bean
    class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <property name="mediaTypes">
        <map>
            <entry key="json" value="application/json" />
            <entry key="html" value="text/html" />
        </map>
    </property>
    <property name="viewResolvers">
        <list>
            <bean
                class="org.springframework.web.servlet.view.InternalResourceViewResolver">
                <property name="viewClass"
                    value="org.springframework.web.servlet.view.JstlView" />
                <property name="prefix" value="/jsp/" />
                <property name="suffix" value=".jsp" />
            </bean>
        </list>
    </property>
    <property name="defaultViews">
        <list>
            <bean
                class="org.springframework.web.servlet.view.json.MappingJacksonJsonView">
                <property name="prefixJson" value="false" />
                <property name="objectMapper" value="jacksonObjectMapper" />
            </bean>
        </list>
    </property>
</bean>

public class ConversionServiceAwareObjectMapper extends ObjectMapper {
@Autowired
public ConversionServiceAwareObjectMapper(
        ConversionService conversionService) {
    AnnotationIntrospector introspector = AnnotationIntrospector.pair(
            new FormatAnnotationIntrospector(conversionService),
            DEFAULT_ANNOTATION_INTROSPECTOR);

    this.setDeserializationConfig(this.getDeserializationConfig()
            .withAnnotationIntrospector(introspector));
    this.setSerializationConfig(this.getSerializationConfig()
            .withAnnotationIntrospector(introspector).withSerializationInclusion(JsonSerialize.Inclusion.NON_NULL));

}

初始化服务器时，出现以下错误：

java.lang.IllegalStateException：无法将[java.lang.String]类型的值转换为属性“Object Mapper”所需的类型[org.codehaus.jackson.map.objectMapper]：在org.springframework.beans.typeConverterDelegate.ConvertifEmental（typeConverterDelegate.java：241）和org.springframework.beans.beanWrapperImpl.ConvertifEmental（beanWrapperImpl.java：470）中找不到匹配的编辑器或转换策略...

我尝试切换到一个普通的视图解析器，只在AnnotationMethodHandler中使用对象映射器，这可以用于服务器启动，但它完全忽略了任何配置。

我完全不知道下一步该做什么。

谢谢你的帮助。

更新：

<property name="objectMapper" value="jacksonObjectMapper" />

与：

<property name="objectMapper" ref="jacksonObjectMapper" />

引用不是值。
