Spring boot can't find the appropriate URL mapping after adding another spring MVC project as a dependency

Question

I am working on a spring boot project which takes service from another spring mvc project. Before I add the service project, URL mapping works perfectly for the spring boot project. But after adding the spring MVC project as a dependency and scanning all the components and mappers, that project can't determine the URL mapping. (two projects have no any compile error)

This is my controller for spring boot project

@Controller
public class PriceFactorController {

    private static final Logger logger = LoggerFactory.getLogger(PriceFactorController.class);


/*

  @Autowired
    PriceAggregator2 priceAggregator2;
*/

    @GetMapping("/price")
    public ModelAndView priceGet() {
        ModelAndView modelAndView = new ModelAndView();
        PriceSearch priceSearch = new PriceSearch();
        modelAndView.addObject("priceSearch", priceSearch);
        modelAndView.setViewName("price");
        return modelAndView;
    }

    @PostMapping("/price")
    public ModelAndView pricePost(
            @Valid @ModelAttribute("priceSearch") PriceSearch priceSearch,
            BindingResult bindingResult,
            Model model) {

        priceSearch.makeDestinationList();
        priceSearch.makeTravellerList();

        //  List<PricingResult> resultSet=priceAggregator2.getPriceResultList(priceSearch.getPriceSearchDTO());

        ModelAndView modelAndView = new ModelAndView();
        logger.debug(priceSearch.toString());
        if (bindingResult.hasErrors()) {
            modelAndView.setViewName("price");
        } else {
            modelAndView.setViewName("redirect:/result");
        }
        return modelAndView;
    }


    @GetMapping("/result")
    public ModelAndView priceResult(
            @RequestParam(value = "key", required = false) String key,
            Model model) {
        Result result = new Result();
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("result", result);
        modelAndView.setViewName("result");
        return modelAndView;
    }
}

But it doesn't seems to look for this controller, Here are my logs..

Additionally,

package lk.xxc;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

//http://www.thymeleaf.org/doc/articles/layouts.html'
@MapperScan("com.xxc")
@ComponentScan(basePackages = {"com.xxc"})
@SpringBootApplication(exclude = {SecurityAutoConfiguration.class })
public class SpringBootWebApplication {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SpringBootWebApplication.class, args);
    }

}

This is the dependency I added

   <dependency>
            <groupId>com.xxc</groupId>
            <artifactId>price-engine</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>

Answer 1

You would have to add the base packages for both projects.

@ComponentScan(basePackages = {"com.xxc", "lk.xcc"})
@SpringBootApplication(exclude = {SecurityAutoConfiguration.class })
public class SpringBootWebApplication {

  public static void main(String[] args) throws Exception {
    SpringApplication.run(SpringBootWebApplication.class, args);
  }
}

This will scan components in both com.xxc and lk.xcc

Answer 2

Where is your @RequestMapping

@RestController
@RequestMapping("/api/v1/price-factor")
public class PriceFactorController{
.......
}
