@Controller
@EnableAutoConfiguration
public class ControllerShowInfo
{
@RequestMapping("/")
public String rawPage()
{
return "rawPage";
}
@Autowired
stockreviewsRepositoryDao repository;
@RequestMapping("/getBaseInfo")
@ResponseBody
public JSONArray getReviewsInfo()
{
JSONArray jsonArray = new JSONArray();
for (stockreviewsBean reviewBean : repository.findAll())
{
jsonArray.put(reviewBean);
System.out.println(reviewBean.getTitle());
}
return jsonArray;
}
public static void main(String[] args) throws Exception
{
SpringApplication.run(ControllerShowInfo.class, args);
}
}
这是控制器层。spring boot,没有发现依赖性的bean类型:预计至少有1个bean符合此依赖关系的自动导向候选项
public interface stockreviewsRepositoryDao extends CrudRepository<stockreviewsBean,String>
{
}
这是道层。当我运行ControllerShowInfo.class时,我使用了 。这里有一个问题如下:
org.springframework.beans.factory.UnsatisfiedDependencyException:错误创建名为“controllerShowInfo”豆:不满意依赖通过现场“仓库”表示:式中没有合格豆[com.yxzh .mapper.stockreviewsRepositoryDao]找到依赖关系[com.yxzh.mapper.stockreviewsRepositoryDao]:预计至少有1个bean有资格作为这个依赖关系的autowire候选。依赖注释:{@ org.springframework.beans.factory.annotation.Autowired(required = true)};嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException:找不到符合[com.yxzh.mapper.stockreviewsRepositoryDao]类型的[com.yxzh.mapper.stockreviewsRepositoryDao]类型的合格bean:期望至少1个符合自动装配候选为此依赖。依赖注释:
但是当我再跑的.class
@SpringBootApplication
public class Application
{
public static void main(String[] args) throws Exception
{
SpringApplication.run(Application.class, args);
}
}
和实施CommmandLineRunner
@Component
public class DataInitialization implements CommandLineRunner{
@Autowired
stockreviewsRepositoryDao repository;
@Override
public void run(String... args) throws Exception
{
System.out.println("-------------------------------");
int count=0;
for (stockreviewsBean reviewBean : repository.findAll())
{
count++;
System.out.println(reviewBean.getTitle());
}
System.out.println(count);
}
}
它运作良好。它真的让我困惑。
是您的stockreviewsRepositoryDao与@库注解/ @组件/ @服务? – ByeBye
我试过了,但没有奏效。所以我删除了@ Repository/@ Component/@ Service。 –
