springmvc4 json

springmvc4 集成hibernate4 出现

NoClassDefFoundError:com/fasterxml/jackson/core/JsonProcessingException

springmvc4 JSON 的配置发生了变化:

     <bean
         class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
         <property name="messageConverters">
             <list>
                 <ref bean="mappingJackson2HttpMessageConverter" />
             </list>
         </property>
     </bean>
     <bean id="mappingJackson2HttpMessageConverter"
         class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
         <property name="supportedMediaTypes">
             <list>
                 <value>text/html;charset=UTF-8</value>
                 <value>text/json;charset=UTF-8</value>
                 <value>application/json;charset=UTF-8</value>
             </list>
         </property>
     </bean>

用到的json包分别为：

jackson-annotations-2.5.0.jar

jackson-core-2.5.0.jar

jackson-databind-2.5.0.jar
