我想通过swagger发布方法并执行，但是我有一个错误。我不知道这个错误来自控制器、服务、dao或config swagger。

我的项目结构：项目结构

应用配置。java（在包com.project.maven.config中）

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("**/**")
    .addResourceLocations("classpath:/META-INF/resources/");
}       

SwaggerConfig.java：

@Configuration
@EnableSwagger2
public class SwaggerConfig {                                    

    @Bean
    public Docket simpleDiffServiceApi() {
      return new Docket(DocumentationType.SWAGGER_2)
      .groupName("calculator")
      .apiInfo(apiInfo())
      .select()
      .apis(RequestHandlerSelectors.any())
      .paths(PathSelectors.any())
      .build()
      .pathMapping("/");
    }

    private ApiInfo apiInfo() {
          return new ApiInfoBuilder()
          .title("A simple service")
          .description("A simple REST service made with Spring Boot in Java")
          .contact(new Contact("Unmesh Gundecha", "http://unmesh.me", "upgundecha@gmail.com"))
          .version("1.0")
          .build();
        }
}

用户控制器:

@RestController
public class UserController {

    @Autowired
    private UserService userService;

    @PostMapping(value={"/tesinsert"}, consumes={"application/json"})
    @ResponseStatus(HttpStatus.OK)
    public ResponseEntity<?> insert(@RequestBody KasusEntity user, 
            @ModelAttribute("init_load") Map<String, String> init) throws Exception {
        Map result = new HashMap(); 
        userService.insertTabel(user);
        return new ResponseEntity<>(result, HttpStatus.CREATED);
    }   

}

用户服务.java：

public interface UserService {
    public int insertTabel(KasusEntity user);
}

用户服务Impl.java：

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserDao userDao;

    @Override
    public int insertTabel(KasusEntity user) {
        return userDao.insert(user);
    }

}

userDao.java:

public interface UserDao {
    public int insert(KasusEntity user);
}

userDaoImpl.java：

@Repository
public class UserDaoImpl implements UserDao {

    @Autowired
    private SessionFactory sessionFactory;

    @Transactional
    public int insert(KasusEntity tabel) {
        return (int) this.sessionFactory.getCurrentSession().save(tabel);
    }

}

错误：

2017年5月23日下午3:27:17 org . Apache . catalina . core . standardwrappervalve在路径为[/SpringNew]的上下文中调用servlet [dispatcher]的SEVERE: Servlet.service()抛出异常[请求处理失败；嵌套异常为org . spring framework . beans . bean instantiation异常:无法实例化[java.util.Map]:指定的类是一个接口]根本原因为org . spring framework . beans . bean instantiation异常:无法实例化[java.util.Map]:指定的类是org . spring framework . beans . bean utils . instantiate class(bean utils . Java:99)处的接口，位于org . spring framework . web . method . annotation . modeattributemethodprocessor . create attribute(modelattributemethodprocessor . Java:141)

如何解决这个问题？swagger配置可能出错吗？因为我自信错误不在控制器，道，服务。可能是配置或其他。

谢谢。
