严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cn.qingyou.elec.dao.impl.DeviceDaoImpl':
这是什么情况。
public interface DeviceDao extends BaseDao<Device> {
public final static String SERVICE_NAME="cn.qingyou.elec.dao.impl.DeviceDaoImpl";
}
@Repository(DeviceDao.SERVICE_NAME)
public class DeviceDaoImpl extends BaseDaoImpl<Device> implements DeviceDao {
}
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cn.qingyou.elec.dao.impl.DeviceDaoImpl':
这是什么情况。
public interface DeviceDao extends BaseDao<Device> {
public final static String SERVICE_NAME="cn.qingyou.elec.dao.impl.DeviceDaoImpl";
}
@Repository(DeviceDao.SERVICE_NAME)
public class DeviceDaoImpl extends BaseDaoImpl<Device> implements DeviceDao {
}
cn.qingyou.elec.dao.impl.DeviceDaoImpl
更正一下:
出错:org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cn.qingyou.elec.dao.impl.DeviceDaoImpl': Injection of resource methods failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory
这是什么情况。
