java - Failed to instantiate Pageable bean

Question

I use Spring 4.1.6.RELEASE and Spring Data Jpa 1.8.0.RELEASE. I have a problem with org.springframework.data.domain.Pageable bean creation. It is used in my controller:

@Controller
public class ItemsController {

    @Autowired
    ProductService itemsService;

    @RequestMapping(value = "/openItemsPage")
    public String openItemsPage() {
        return "items";
    }

    @RequestMapping(value = "/getItems", method = RequestMethod.GET)
    @ResponseBody
    public Item[] getItems(Pageable pageable) {

        return itemsService.getItems(pageable);
    }
}

Also I have a next xml configurations in my application context:

<context:component-scan base-package="com.mobox.controller" />

<mvc:annotation-driven>
    <mvc:argument-resolvers>
        <beans:bean id="sortResolver"
                class="org.springframework.data.web.SortHandlerMethodArgumentResolver" />
        <beans:bean
                class="org.springframework.data.web.PageableHandlerMethodArgumentResolver">
            <beans:constructor-arg ref="sortResolver" />
        </beans:bean>
    </mvc:argument-resolvers>
</mvc:annotation-driven>

And finaly I do A next requsr from the client:

   $.ajax({
        type: "GET",
        url: "getProducts?page=0&size=100",
        .....

In tomcat log I see next:

    SEVERE: Servlet.service() for servlet [appServlet] in context with path [/a2delivery-web] threw exception [Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.domain.Pageable]: Specified class is an interface] with root cause

Please help me to resolve this issue, thanks!

Answer 1

The easiest way to get this working is to set @EnableSpringDataWebSupport in your configuration. Alternatively, in a pure XML based configuration, declare SpringDataWebConfiguration as Spring bean.

That will make sure the necessary HandlerMethodArgumentResolver will be registered correctly.
