当我运行以下代码时,我收到错误“调用init方法失败;嵌套异常是java.lang.IllegalArgumentException:'sessionFactory'或'hibernateTemplate'是必需的”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;
}
AbstractHibernateDao.java
public abstract class AbstractHibernateDao extends HibernateDaoSupport {
public Session getSession() {
HibernateTemplate template = this.getHibernateTemplate();
template.setSessionFactory(getSessionFactory());
return template.getSessionFactory().openSession();
}
错误信息是:

现在我收到了这个错误:
"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?
答案 0 :(得分:2)
自hibernate 3.0.1以来,不鼓励使用HibernateTemplate
,它引入了对上下文会话的支持(大约在2008年!)。如今,我们鼓励/建议您针对the plain Hibernate API撰写DAO。
然后说要将你的DAO重写为以下内容。
public abstract class AbstractHibernateDao {
@Autowired
private SessionFactory sessionFactory;
protected Session getCurrentSession() {
return sessionFactory.getCurrentSession();
}
}
现在你实际实施的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;
}
这里有几个假设。
HibernateTransactionManager
@Transactional
@EnableTransactionManagement
或<tx:annotation-driven />
的交易。 这个Spring负责为你打开/关闭Session
,你不必再考虑它了。
