Question

我正在尝试使用EntityManager进行aspectj，它给出错误

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.

驱动程序应用程序：

@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");
        }
    }
}

服务类：

@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");
}

方面：

   @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

需要知道哪里出错了？

Answer 1

正如消息所说......它需要一个Bean Validation API（JSR 303）提供程序。如果你把一个像Hibernate-Validator或Apache BVAL这样的提供程序放在你的CLASSPATH中，我希望消息能够消失。

带有aspectj的EntityManager无法正常工作
