jersey + spring + jpa + hibernate配置在类路径资源[applicationContext.xml]中定义创建名为'entityManagerFactory'的bean

标签： spring hibernate maven jpa jersey

我正在使用jersey spring jpa和hibernate以及mysql db。这里我遇到了一些问题错误： - 在类路径资源[applicationContext.xml]中定义了名为'entityManagerFactory'的bean。我浪费了最近3天，但我无法找到解决问题的方法。请指导我解决这个问题。

package com.mind.rest;

@Controller
@Path("/payment")
public class PaymentService {

    @Autowired
    TransactionBo transactionBo;

    @GET
    @Path("/saveTransaction")
    public Response savePayment() {

        String result = transactionBo.save();

        return Response.status(200).entity(result).build();

    }

    @GET
    @Path("/getAllTransaction")
    public Response getAllTransaction() {
        List<Account> result = transactionBo.getAllTransaction();

        return Response.status(200).entity(result).build();
    }
}

package com.mind.transaction;

public interface TransactionBo {

    public String save();

    public List<Account> getAllTransaction();
}

package com.mind.transaction.impl;
  @Service
public class TransactionBoImpl implements TransactionBo{

    private EntityManager entityManager;


    public EntityManager getEntityManager() {
        return entityManager;
    }
    public void setEntityManager(EntityManager entityManager) {
        this.entityManager = entityManager;
    }
    public String save() {

        return "Jersey + Spring example";

    }
    @SuppressWarnings("unchecked")
    @Transactional
    public List<Account> getAllTransaction(){
        Query query = entityManager.createNamedQuery("Account.findAll");
        List<Account> accounts;
        accounts = query.getResultList();
        return accounts;

    }


}

package com.mind.entity;
@Entity
@Table(name="account")
@NamedQuery(name="Account.findAll", query="SELECT a FROM account a") 
public class Account {

    @Id
    @Column(name="accountnumber")
    private int accountNumber;

    @Column(name="owner")
    private String owner;

    @Column(name="balance")
    private double balance;

    public Account(){}

    public Account(int accountNumber, String owner, double balance) {
        this.accountNumber = accountNumber;
        this.owner = owner;
        this.balance = balance;
    }
    setter & getter
}

答案 0 :(得分：1)

命名查询中存在错误。如果它不是本机查询，则必须在JPQL中制定查询。这意味着表名是实体类的名称。请尝试：

选择一个FROM帐户作为

或使用命名的本机查询（@NamedNativeQuery）
