java - 调用init方法失败；嵌套异常是 java.lang.IllegalArgumentException : 'sessionFactory' or 'hibernateTemplate' is required

Question

当我运行以下代码时，出现错误“调用 init 方法失败；嵌套异常为 java.lang.IllegalArgumentException:需要 'sessionFactory' 或 'hibernateTemplate'” 我的代码中的错误是什么？

EmployeeDaoImpl.java

@Repository
public class EmployeeDaoImpl extends AbstractHibernateDao implements EmployeeDao{
public Employee getSalaryDetails(Integer empId)
{
    Session session = getSession();
    Query query = session.getNamedQuery("getEmpSalaryDtls");
    query.setInteger("empId", empId);
    query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
    Map map = (Map) query.uniqueResult();
    closeSession(session);
    return map;
}

抽象HibernateDao.java

public abstract class AbstractHibernateDao extends HibernateDaoSupport {
public Session getSession() {       
    HibernateTemplate template = this.getHibernateTemplate();       
    template.setSessionFactory(getSessionFactory());
    return template.getSessionFactory().openSession();
}

错误消息是:

现在我得到了这个错误:

"org.springframework.web.struts.ContextLoaderPlugIn" "Context initialization failed"
 org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'EmployeeServiceImpl': Unsatisfied dependency expressed through field 'EmployeeDao'; nested exception is 
 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'EmployeeDao' defined in ServletContext resource [/WEB-INF/spring-beans.xml]: Error setting property values; nested exception is 
 org.springframework.beans.NotWritablePropertyException: Invalid property 'hibernateTemplate' of bean class [com.temp.EmployeeDaoImpl]: Bean property 'hibernateTemplate' is not writable or has an invalid setter method. 
 Does the parameter type of the setter match the return type of the getter?

Answer 1

使用HibernateTemplate自 hibernate 3.0.1 引入对上下文 session 的支持(大约在 2008 年!)以来，它就不再被鼓励了。现在，我们鼓励/建议您编写一个针对 the plain Hibernate API 的 DAO。 .

话虽如此，将您的 DAO 重写为以下内容。

public abstract class AbstractHibernateDao {

    @Autowired
    private SessionFactory sessionFactory;

    protected Session getCurrentSession() {
        return sessionFactory.getCurrentSession();
    }
}

现在您实际实现的 DAO

@Repository
public class EmployeeDaoImpl extends AbstractHibernateDao implements EmployeeDao{
public Employee getSalaryDetails(Integer empId)
{
    Session session = getCurrentSession();
    Query query = session.getNamedQuery("getEmpSalaryDtls");
    query.setInteger("empId", empId);
    query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
    Map map = (Map) query.uniqueResult();
    return map;
}

这里做了一些假设。

1. 您已通过 HibernateTransactionManager 进行了正确的交易设置
2. 您有一笔来自 @Transactional 的服务的实际交易
3. 您已启用 @EnableTransactionManagement 的交易或<tx:annotation-driven /> 。

今年 Spring 负责打开/关闭 Session对于你来说，你不必再考虑它了。
