EntityManager的使用AspectJ不工作

Question

我試圖與EntityManager的，它給錯誤

org.springframework.beans.factory.BeanCreationException: 
    Error creating bean with name 
    'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration', 
    Add a provider like Hibernate Validator (RI) to your classpath. 

POM的AspectJ：

<parent> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-parent</artifactId> 
     <version>1.3.5.RELEASE</version>

     <dependency>

     <dependency>

         </goals> 
        </execution> 
       </executions> 
      </plugin> 
     </plugins> 

驅動程序：

@SpringBootApplication 
@ComponentScan(basePackages = "aspect.*") 
@EnableAspectJAutoProxy 
@Configuration 
@EntityScan(basePackages ="aspect.*") 
public class Application{ 

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

     try { 
      Service service=context.getBean(Service.class); 
      service.save(); 

     } catch (RuntimeException e) { 
      System.out.println("Caught runtime exception"); 
     } 
    } 
} 

服務類：

@Component 
public class Service{ 

    @Autowired 
    EntityManager entityManager; 

    @Transactional 
    public void save() { 
     System.out.println("Before Invocation"); 
     entityManager.persist(new Employee("009", "sunitha", "Lead")); 
     System.out.println("after persist call"); 
} 

看點：

@Aspect 
    @Component 
    public class AuditAspect { 

     @Around("execution(* javax.persistence.EntityManager.persist(..)) && @annotation(loggable)") 
    public Object aroundServce(ProceedingJoinPoint joinPoint, Loggable loggable) throws Throwable{ 
    long start = System.currentTimeMillis(); 
     // System.out.println("start--> "+start); 
     Object result = joinPoint.proceed(); 
     Logger.info(this, "info %s just called", MethodSignature.class.cast(joinPoint.getSignature()).getMethod().getName()); 
     return result; 
    } 

    } 

application.properties：

spring.jpa.show-sql=true 
spring.jpa.hibernate.ddl-auto=update 

需要知道在哪裏做錯了？

正如消息所說......它需要一個Bean驗證API（JSR 303）提供程序。如果你在你的CLASSPATH中放置了一個像Hibernate-Validator或Apache BVAL這樣的提供者，我希望消息消失。
