springmvc 拦截器解析json数据后不能跳转到controller

<mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <constructor-arg value="UTF-8" />
            </bean>
            <bean
                class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                <property name="objectMapper">
                    <bean class="com.fasterxml.jackson.databind.ObjectMapper">
                        <property name="dateFormat">
                            <bean class="java.text.SimpleDateFormat">
                                <constructor-arg type="java.lang.String" value="yyyy-MM-dd HH:mm:ss" />
                            </bean>
                        </property>
                    </bean>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

这是我的json配置在springmvc-servlet.xml添加的。

在代码中这样写的

@RestController
public class BookController extends BaseController {
    @Autowired
    public BookService bookService;
    @RequestMapping(value = "/getBook.do")
    public Map<String, Object> getBook() {
        dataMap.put(RESULT, SUCCESS);
        dataMap.put(MESSAGE, bookService.findbyId("1"));
        return dataMap;
    }

}
