一定是漏了Jackson相關jar包，需要3個jar包，下載之後匯入：

jackson-annotations-2.6.jar

jackson-databind-2.6.jar

jackson-core-2.6.jar

同時在springmvc-servlet.xml中增加配置：

	<!-- json轉換器 -->
	<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>
