Question

下面是注入sessionFactory的EmployeeDaoImpl文件。

@Repository 公共类EmployeeDaoImpl实现EmployeeDao {

@Autowired
    private SessionFactory sessionFactory; 

@Override
public void addEmployee(TestEmployee employee) { 
    this.sessionFactory.getCurrentSession().save(employee); 
} 

@SuppressWarnings("unchecked") 
@Override
public List<TestEmployee> getAllEmployees() { 
    return this.sessionFactory.getCurrentSession().createQuery("from TestEmployee").list(); 
} 

@Override
public void deleteEmployee(Integer employeeId) { 
    TestEmployee employee = (TestEmployee) sessionFactory.getCurrentSession().load( 
            TestEmployee.class, employeeId); 
    if (null != employee) { 
        this.sessionFactory.getCurrentSession().delete(employee); 
    } 
}

}

以下是我的employee-servlet文件

我收到An AnnotationConfiguration实例是必需的错误。我在网上搜索过但无法解决这个问题。我有运行配置。我正在使用hibernate 3和spring 3.1 JARS。请帮助

Answer 1

daoin

<context:component-scan base-package="com.rights.controller" />

您似乎忘记了存储库的包，您应该使用以下方法添加它：

<context:component-scan base-package="com.rights.controller com.rights.dao" />

在您发布的配置中，带有注释@Repository的类可能不会被spring进行后处理，如果它包不包含在组件扫描中

我希望它可以帮到你

使用<myclass> </myclass>需要AnnotationConfiguration实例
