私のアプリケーションのサービスでDAOをオートワイヤリングする際に問題があります。サービスでDAOをオートワイヤできない
マイコントローラ：（正しくAutowires PurchaseService）
package com.app.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import com.app.common.web.RestPreconditions;
import com.app.model.Purchase;
import com.app.service.IPurchaseService;
@Controller
public class PurchaseController {
@Autowired
private IPurchaseService purchaseService;
@RequestMapping(value = "purchase", method = RequestMethod.GET)
@ResponseBody
public final String getAll() {
return "HELLO";
}
}
マイPurchaseService：
package com.app.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.app.model.Purchase;
import com.app.persistence.dao.PurchaseDAO;
@Service
public class PurchaseService implements IPurchaseService {
@Autowired
private PurchaseDAO purchaseDAO;
@Transactional
public List<Purchase> getAll()
{
return purchaseDAO.findAll();
}
}
マイPurchaseDAO：
package com.app.persistence.dao;
import org.springframework.stereotype.Repository;
import com.app.model.Purchase;
import com.app.persistence.AbstractJpaDAO;
@Repository
public class PurchaseDAO extends AbstractJpaDAO<Purchase> implements IPurchaseDAO {
public PurchaseDAO() {
setClazz(Purchase.class);
}
}
AbstractJpaDAO：
package com.app.persistence;
import java.io.Serializable;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
public abstract class AbstractJpaDAO<T extends Serializable> {
private Class<T> clazz;
@PersistenceContext
EntityManager entityManager;
public void setClazz(final Class<T> clazzToSet) {
this.clazz = clazzToSet;
}
public T findOne(final Long id) {
return entityManager.find(clazz, id);
}
public List<T> findAll() {
return entityManager.createQuery("from " + clazz.getName())
.getResultList();
}
}
購入モデル：
package com.app.model;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
public class Purchase implements Serializable {
/**
*
*/
private static final long serialVersionUID = 6603477834338392140L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "ID")
private Long id;
@Column(name = "PAN")
private Long pan;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Long getPan() {
return pan;
}
public void setPan(Long pan) {
this.pan = pan;
}
}

私PurchaseDAOがautowiredされていない理由を任意のアイデア？
@Autowired
private IPurchaseDAO purchaseDAO;
またはCGLIBクラスのプロキシを有効にします。
おかげ
を追加しましたか？コンテキストXMLファイルに<コンテキスト：コンポーネント：スキャンベースパッケージ= "com.app.persistence.dao" />を追加しましたか？ – BraginiNI
私は確かにブラジニを持っています。 Javaの設定で追加されました。 –
