How to create multiple instances of RestController in Spring boot application?

I want to create different instances of Spring RestController with different instances of beans (service, dao, cache) injected.

Currently, we have implemented this with JAX-RS Restful API.

But when I try to implement the same in Spring RestController, I'm getting below error when Spring tries to create a new bean "product2RestController".

Because bean "product1RestController" is already mapped to the rest url and created.

Stacktrace:

Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'product2RestController' method

@Path("/products")
public class ProductLookupRestService {

    @Context
    HttpServletRequest httpServletRequest;

    @Context
    HttpServletResponse httpServletResponse;

    @Context
    UriInfo uriInfo;

    private Map<Integer, AbstractProductRestService> productServiceLoopup;

    public void setProductServiceLoopup(Map<Integer, AbstractProductRestService> productServiceLoopup) {
        this.productServiceLoopup = productServiceLoopup;
    }

    @Path("/{productId}")
    public AbstractProductRestService getReport(@PathParam("productId") int productId) {
        AbstractProductRestService productRestService = this.productServiceLoopup.get(productId);
        productRestService.setHttpServletRequest(httpServletRequest);
        productRestService.setHttpServletResponse(httpServletResponse);
        productRestService.setUriInfo(uriInfo);

        return productRestService;
    }
}

public abstract class AbstractProductRestService {

    @Context
    protected HttpServletRequest httpServletRequest;

    @Context
    protected HttpServletResponse httpServletResponse;

    @Context
    protected UriInfo uriInfo;

    protected IProductService productService;
    protected IProductCache productCache;

    public void setHttpServletRequest(HttpServletRequest httpServletRequest) {
        this.httpServletRequest = httpServletRequest;
    }

    public void setHttpServletResponse(HttpServletResponse httpServletResponse) {
        this.httpServletResponse = httpServletResponse;
    }

    public void setUriInfo(UriInfo uriInfo) {
        this.uriInfo = uriInfo;
    }

    public void setProductService(IProductService productService) {
        this.productService = productService;
    }

    public void setProductCache(IProductCache productCache) {
        this.productCache = productCache;
    }

    @POST
    @Path("/filters")
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public Response createFilters(Form filterForm) {
        //Save the filters and return uuid
        ResponseBuilder responseBuilder = Response.created(uriInfo.getAbsolutePathBuilder().path("uuid").build());

        return responseBuilder.build();
    }
}

public class ProductRestService extends AbstractProductRestService {

    @GET
    @Path("/filters/{uuid}/detail")
    public String getProductDetail(){
        // do cache check : productCache
        return this.productService.readProductDetail();
    }
}

public class ProductServiceImpl implements IProductService{

    @Override
    public String readProductDetail() {
        // Call to dao to get the data
        return null;
    }

}

<bean id="product1RestService" class="com.poc.jaxrs.rest.ProductRestService">
        <property name="productService" ref="product1Service"/>
        <property name="productCache" ref="product1Cache"/>
    </bean>

    <bean id="product2RestService" class="com.poc.jaxrs.rest.ProductRestService">
        <property name="productService" ref="product2Service"/>
        <property name="productCache" ref="product2Cache"/>
    </bean>

    <bean id="restProductLookupService" class="com.poc.jaxrs.rest.ProductLookupRestService">
        <property name="productServiceLoopup">
            <map key-type="java.lang.Integer">
                <entry key="1"><ref bean="product1RestService"/></entry>
                <entry key="2"><ref bean="product2RestService"/></entry>
            </map>
        </property>
    </bean>

I use below like urls to invoke service.

POST Call: http://localhost:8080/productservice/products/1/filters

GET Call: http://localhost:8080/productservice/products/1/filters/uuid/detail

In my spring application context xml, I'm creating multiple instances of ProductRestService class with different beans (service, cache) instances injected.

Same way I want to create multiple instances of Spring RestController, But I'm getting Ambiguous mapping error.

Thanks for your help in advance.
