java.lang.IllegalArgumentException：spring hibernate中需要’sessionFactory’或’hibernateTemplate’

我正在做spring hibernate apllication.当我在tomcat服务器上运行应用程序时,我遇到了一些异常.以下是我的代码.

这是我的bean配置文件.

spring-beans-2.5.xsd">

 fig.PropertyPlaceholderConfigurer">
    factorybean">

        sql">true

这是我的道教班.

public class EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao {

    private SessionFactory sessionFactory;
    public EmployeeDaoImpl(SessionFactory sessionfactory){
        this.sessionFactory=sessionfactory;
    }

    @Override
    public List

这里另一个类employeeBo正在调用employeeDaoImpl.
当我运行这个我得到以下异常.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeBo' defined in ServletContext resource [/WEB-INF/spring/EmployeeBean.xml]: Cannot resolve reference to bean 'employeeDao' while setting bean property 'employeeDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeDao' defined in ServletContext resource [/WEB-INF/spring/EmployeeBean.xml]: Invocation of init method Failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required

任何人都可以帮助解决这个问题.我已经尝试了很多并谷歌它.但确实得到了解决方案.

最佳答案

如果您有两个配置文件,则复制’sessionFactory’定义.删除其中一个’sessionFactory’定义.在IllegalArgumentException之前,您将遇到重复的bean定义异常.

编辑：评论后,

public class EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao {


public EmployeeDaoImpl(SessionFactory sessionfactory){
    setSessionFactory(sessionfactory);
}

@Override
public List

或者在上面的代码中删除构造函数并使用setter注入注入’sessionFactory’.请参阅org.springframework.orm.hibernate3.support.HibernateDaoSupport.setSessionFactory(SessionFactory).我更喜欢后来的方法.
