在SpringMvc中使用Jackson实现Json输出时，如配置如下：

<bean id="mappingJacksonHttpMessageConverter"  
        class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">  
        <property name="supportedMediaTypes">  
            <list>  
                <value>text/html;charset=UTF-8</value>  
            </list>  
        </property>  
    </bean>


启动时出现异常：

2016-02-06 10:55:53,453 DEBUG [springframework.beans.factory.support.DefaultListableBeanFactory] - Creating shared instance of singleton bean 'mappingJacksonHttpMessageConverter'

错误原因是 找不到对应的类，引入org.codehaus的Jackson包 即可

maven

<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.9.13</version>
</dependency>


问题解决！
