initメソッドの呼び出しに失敗しました。入れ子にされた例外はjava.lang.IllegalArgumentExceptionです： 'sessionFactory'または 'hibernateTemplate'が必要です

Question

私は次のコードを実行すると "initメソッドの呼び出しに失敗しました。 'hibernateTemplate'は必須です "私のコードのエラーは何ですか？

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(); 
}

今、私はこのエラーを得た：

"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

HibernateTemplateの使用は、（約2008年頃だった）コンテキストセッションのサポートを導入したhibernate 3.0.1以降はお勧めできません。今日、あなたはthe plain Hibernate APIに対してDAOを書くことを勧められています。

これでDAOを次のように書き直しました。

public abstract class AbstractHibernateDao { 

    @Autowired 
    private SessionFactory sessionFactory; 

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

今、あなたの実際の実装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; 
} 

ここでの仮定がいくつかあります。

1. あなたはあなたが@EnableTransactionManagementか<tx:annotation-driven />との取引を有効にしている@Transactional
2. とサービスから実際のトランザクションを持ってHibernateTransactionManager
3. との適切な取引を設定しています。

このスプリングでは、Sessionの開閉を行いますので、これ以上考えないでください。
