从 Jboss 4.2.2 Spring 2 到 Jboss 6 Spring 3 配置 JPA 实体管理器时出现问题

Question

当 jboss6 spring 3 JPA2 休眠时 EntityManager 为 null（未注入）

尝试将在 Jboss4.2.2 Spring 2 上运行的现有应用程序迁移到 Jboss 6 Spring 3

经过多次尝试，应用程序已正确部署，但在执行（调试）时，entityManager 为空）。我是否错过了注入 EM 的地点和时间，因为 Spring 2 下的旧 Application.xml 有很多更改

我有一个 persistence.xml 文件（Spring 3 jboss 6 的新文件）< /strong>

<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">`
<persistence-unit name="boxPU" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/BoxMysqlDS</jta-data-source>
<class>box.business.Customer</class>

</persistence>

服务类

package box.service;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import box.dao.CustomerDao;
public class BoxManagerImpl implements BoxManager {
@PersistenceContext(unitName = "boxPU")
private EntityManager entityManager;
private CustomerDao customerDao;


public void setcustomerDao(CustomerDao customerDao) {
    this.customerDao = customerDao;
}

public String test() {


    boolean retour = customerDao.isEmailAlreadyUsed("[email protected]");

    return "valeur retour :"+ retour;

}}

DAO类

package box.dao;
import javax.persistence.EntityManager;
import javax.persistence.NoResultException;
import javax.persistence.PersistenceContext;
import javax.persistence.PersistenceException;
import javax.persistence.Query;
import org.springframework.transaction.annotation.Transactional;
import box.business.Customer;
@Transactional
public class CustomerDaoImpl implements CustomerDao {
@PersistenceContext(unitName = "boxPU")
private EntityManager entityManager;

public boolean isEmailAlreadyUsed(String email) {

        String SQL_SELECT_CUSTOMER_EXISTS = " select c from " + " "
            + Constants.SQL_CUSTOMER_TABLE + " c, " + " "
            + Constants.SQL_STATUS_TABLE + " s "
            + " where c.status.statusid=s.statusid " + " and c.email='"
            + email.toLowerCase() + "'";

        boolean customerexists = false;

        if (email == null || email.equals(""))
        throw new DaoException("email null in isCustomerExists ", 10);

    Customer customer = null;
    try {
        customer = (Customer) entityManager.createQuery(
                SQL_SELECT_CUSTOMER_EXISTS).getSingleResult();
        customerexists = (customer == null) ? false : true;
    } catch (NoResultException exception) {
        customerexists = (customer == null) ? false : true;
    }

catch (PersistenceException exception) {
        throw new DaoException(exception.getMessage(),
                Error.CUSTOMER_IS_EMAIL_ALREADY_EXISTS_DAO_ERROR);
    }

    if (customerexists)
        throw new DaoException(
                Error.CUSTOMER_EMAIL_ALREADY_EXISTS_ERROR_MSG,
                Error.CUSTOMER_EMAIL_ALREADY_EXISTS_ERROR);

    return customerexists;
}
}

部署正确，没有错误。但是执行App时，DAO中的entityManger为null。 该应用程序与 Jboss 4.2.2 和 Spring 2 配合良好。 我认为注入机制有问题，我肯定错过了一些东西。 谢谢
