SpringMVC @ResponseBody注解返回Json时出现406 not acceptable

解决

三个jar

jackson-annotions-2.6.0.jar
jackson-core-2.6.4.jar
jackson-databind-2.6.4.jar

AnnotationMethodHandlerAdapter 配置

servlet.xml里面加入

    <bean id="annotationMethodHanlder" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >
        <property name="messageConverters">
          <list>
            <ref bean="jsonp"/>
          </list>
        </property>
    </bean>
    <bean id="jsonp"  class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <bean class="org.springframework.http.MediaType">
                    <constructor-arg value="text"/>
                    <constructor-arg value="json"/>
                        <constructor-arg>
                            <map>
                                <entry key="charset" value="UTF-8" />
                            </map>
                    </constructor-arg>
                 </bean>
            </list>
        </property>
    </bean>

其他

至于用 <mvc:annotation-driven /> 配置xml什么的我并没有用到
