이 스크립트로 작성된 데이터베이스의 활동 테이블 :

CREATE TABLE IF NOT EXISTS `Example`.`Activity` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `Name` VARCHAR(32) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE INDEX `id_UNIQUE` (`id` ASC))
ENGINE = InnoDB

다음은 Model 클래스입니다.

package com.example.web.model;

public class Activity
{
    private int id;
    private String name;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

이것은 내 servlet-context.xml입니다.

        <constructor-arg>
            <ref bean="sessionFactory" />
        </constructor-arg>
    </bean>

</beans>

다음은 ActivityDAO입니다.

package com.example.web.dao;

import java.util.List;
import com.example.web.model.Activity;
import org.hibernate.Criteria;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Transactional;

public class ActivityDAO implements IActivityDAO
{
    private SessionFactory sessionFactory;

    public ActivityDAO(SessionFactory sessionFactory)
    {
        this.sessionFactory = sessionFactory;
    }

    @Override
    @Transactional
    public List<Activity> All()
    {
        @SuppressWarnings("unchecked")
        List<Activity> listActivity = (List<Activity>) sessionFactory.getCurrentSession()
                .createCriteria(Activity.class)
                .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list();

        return listActivity;
    }
}

나는 필드가 적절하게 번역되지 않는 것에 대해 약간의 게시물을 읽었지만 그것은 나를 돕지 않았다. 여기 내가 시도한 것 :

필드 autowire 수 없습니다 : 봄 - 최대 절전 모드

필드 autowire 수 없습니다.

해결법

  1. ==============================

    1.Spring JDK 프록시 메소드를 사용 중입니다. 그리고 귀하의 HomeController는 ActivityDAO 유형과 같은 필드를 갖습니다.

    Spring JDK 프록시 메소드를 사용 중입니다. 그리고 귀하의 HomeController는 ActivityDAO 유형과 같은 필드를 갖습니다.

    @Autowired
private ActivityDAO activityDAO;

    그러나 Spring은 JDK 프록시 메소드를 사용하여 클래스 프록시를 생성 할 수 없습니다.

    activityDAO 필드의 유형을 IActivityDAO로 변경할 수 있습니다.

    @Autowired
private IActivityDAO activityDAO;

    그 문제를 해결할 것입니다.

    프록시 방법에 대한 자세한 내용은 다음을 참조하십시오. http://docs.spring.io/spring/docs/current/spring-framework-reference/html/aop-api.html#aop-pfb-proxy-types
