java - 添加另一个 Spring MVC 项目作为依赖项后 Spring Boot 找不到合适的 URL 映射

Question

我正在开发一个 Spring Boot 项目，该项目从另一个 Spring MVC 项目获取服务。在我添加服务项目之前，URL 映射非常适合 Spring Boot 项目。但是在将 spring MVC 项目添加为依赖项并扫描所有组件和映射器后，该项目无法确定 URL 映射。 (两个项目没有任何编译错误)

这是我的 Spring Boot 项目 Controller

@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;
    }
}

但它似乎并没有寻找这个 Controller ，这是我的日志..

此外，

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);
    }

}

这是我添加的依赖

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

Answer 1

您必须为这两个项目添加基础包。

@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);
  }
}

这将扫描 com.xxc 和 lk.xcc 中的组件
