春季啓動 - 無豆名爲「entityManagerFactory的」可用

Question

我有一個使用JPA和HSQLDB數據持久化一個簡單的Spring啓動的基於Web的應用程序，但現在當我嘗試建立我的項目，它失敗並說：

No bean named 'entityManagerFactory' available 

我的代碼如下：

應用

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.scheduling.annotation.EnableScheduling; 

@SpringBootApplication 
@EnableScheduling 
public class Application { 

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

「Comentario」 表

package dashboard.model; 

import java.util.Date; 

import javax.persistence.*; 

@Entity 
@Table(name="TComentarios") 
public class Comentario { 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long id; 
    private String contenido; 
    @ManyToOne 
    private Sugerencia sugerencia; 
    @ManyToOne 
    private Usuario usuario; 
    @Temporal(TemporalType.DATE) 
    private Date fecha; 

    Comentario(){} 

    get/set... 
} 

庫

import java.util.List; 

import org.springframework.data.jpa.repository.JpaRepository; 
import org.springframework.data.jpa.repository.Query; 
import org.springframework.stereotype.Repository; 

@Repository 
public interface ComentarioRepository extends JpaRepository<Comentario, Long>{ 
@Query("select c from Comentario c where c.sugerencia = ?1") 
List<Comentario> findBySugerencia(Sugerencia sugerencia); 
}

Answer 1

它將也許不能解決你的問題，但覆蓋神器的依賴版本由彈簧引導起動拉不建議使用pom，可能會產生副作用：

<parent> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-parent</artifactId> 
    <version>1.4.4.RELEASE</version> 
</parent>  
....  
<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-data-jpa</artifactId> 
     <version>1.5.2.RELEASE</version> 
</dependency> 

它肩膀d是不夠的：

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-data-jpa</artifactId> 
</dependency> 

確實大部分由啓動POM拉依賴，但它仍然是屬於org.springframework.boot的groupId被設計使用相同版本的工作依賴更真實。
