找不到SpringBoot存儲庫（休眠）

你好我正在使用spring-boot和hibernate創建簡單的webapp。 application.properties文件包含db連接的屬性。貝婁是我的文件：找不到SpringBoot存儲庫（休眠）

應用背景：

package hbwc; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.builder.SpringApplicationBuilder; 
import org.springframework.boot.context.web.SpringBootServletInitializer; 
import org.springframework.context.ApplicationContext; 
import org.springframework.context.annotation.ComponentScan; 

@SpringBootApplication 
public class Application { 

    public static void main(String[] args) { 
     ApplicationContext ctx = SpringApplication.run(Application.class, args); 
    } 
}

Customer實體：

package hbwc.customer; 

import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 

@Entity 
public class Customer { 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private long id; 
    private String firstName; 
    private String lastName; 

    protected Customer() { 
    } 

    public Customer(String firstName, String lastName) { 
     this.firstName = firstName; 
     this.lastName = lastName; 
    } 

    @Override 
    public String toString() { 
     return String.format(
       "Customer[id=%d, firstName='%s', lastName='%s']", 
       id, firstName, lastName); 
    } 

}

客戶資料庫：

package hbwc.customer; 

import org.springframework.data.repository.CrudRepository; 

public interface CustomerRepository extends CrudRepository<Customer, Long> {}

CustomerController：

package hbwc.customer; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RestController; 
import java.util.List; 

@RestController 
public class CustomerController { 

    @Autowired 
    CustomerRepository repository; 

    @RequestMapping("/customers") 
     public String index() { 
     List<Customer> all = (List<Customer>) repository.findAll(); 
     return "ok"; 
    } 
}

我使用gradlew建設和運行這個例子。但我有問題，而運行它（./梯形圖運行）。我收到了一個異常，告訴我找不到我的CustomerRepository。 堆棧跟蹤：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [hbwc.customer.CustomerRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:1301) 
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1047) 
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:942) 
    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:533) 
    ... 18 common frames omitted

請給我一些建議什麼是錯我的代碼。

application.properties（項目根目錄）

spring.datasource.url=jdbc:mysql://localhost/hbwc 
spring.datasource.username=root 
spring.datasource.password=baza1 

spring.jpa.show-sql=true 
spring.jpa.hibernate.ddl-auto=create-drop

您需要配置數據源，並且需要在類路徑上使用彈簧數據的impl（例如spring-data-jpa）。請參閱http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-sql.html – mp911de

在application.properties文件中擁有屬性不夠？ – tomgal

看看這裏的例子看起來好嗎https://spring.io/guides/gs/accessing-data-jpa/。您可以嘗試向您的應用程序配置類添加'@Repository'到您的CustomerRepository接口或'@EnableJpaRepositories'。根據這個例子，這兩者都不需要，但是無論如何都要嘗試。 –

你不必在你的倉庫類中的任何分類元件註釋。嘗試添加@Repository或@Component。然後，您應該（假設啓用了組件掃描）能夠將存儲庫自動裝入您的控制器。
