我想使用 MongoRepository 接口，但我有一个 BeanCreationException 异常。正确填写 ComponentScan 和 MappingBasePackage 字符串。
这是我的代码：
（球衣类）@Component @Path("skills") public class SkillREST {
@Autowired
private UserService userService;
@POST
@Path("/{token}")
@Produces({MediaType.APPLICATION_JSON})
public List<Skill> addSkill(@PathParam("token") String token, Skill skill){
return userService.getAllSkills();
}
}
这是存储库未正确自动装配的服务：
@Component
public class UserService {
@Autowired
SkillRepository skillRepository;
public List<Skill> getAllSkills(){
return skillRepository.findAll();
}
}
@Repository
public interface SkillRepository extends MongoRepository<Skill, String> {
}
弹簧配置类：
@Configuration
@PropertySource("classpath:mongodb.properties")
@EnableMongoRepositories
@ComponentScan("com.headlezz")
public class SpringMongoConfig extends AbstractMongoConfiguration {
@Inject
Environment environment;
@Override
public String getDatabaseName() {
return environment.getProperty("db.name");
}
@Override
@Bean
public Mongo mongo() throws Exception {
return new MongoClient("127.0.0.1");
}
@Override
protected String getMappingBasePackage() {
return "com.headlezz.repository";
}
}
这是输出：

有人可以解释为什么会这样吗？
