1.dao层
@Repository
public class ForecastDao {
@Autowired
private SessionFactory sessionFactory;
//添加预报信息
public boolean addForecast(Forecast forecast)
{

System.out.println("进入add");
Session session=sessionFactory.openSession();
Transaction t=session.beginTransaction();
session.save(forecast);
t.commit();
session.close();
return false;
}
//查询预报信息
public List queryForecast()
{
System.out.println("进入query");
Session session=sessionFactory.openSession();
Transaction t=session.beginTransaction();
//HQL查询语句
String hql="from Forecast";
Query query=session.createQuery(hql);
List list=query.list();
t.commit();
session.close();
return list;
}

实体
@Entity(name="forecast")

@Resource
public class Forecast implements Serializable {
private int forecastId;//预报编号
private String forecastArea;//预报区县
private String forecastTime;//预报时间
private String forecastAir;//天气
private int temperature;//温度
private int humidity;//湿度
private float windSpeed;//风速
private String windDirection;//风向
private float capacity;//降雨量
private float totalCould;//总云量
private float lowCapacity;//低动量
@Id
@GeneratedValue

public int getForecastId() {
    return forecastId;
}
public void setForecastId(int forecastId) {
    this.forecastId = forecastId;
}
@Column(name="forecast_area")
public String getForecastArea() {
    return forecastArea;
}
public void setForecastArea(String forecastArea) {
    this.forecastArea = forecastArea;
}

@Column(name="forecast_time")
public String getForecastTime() {
    return forecastTime;
}
public void setForecastTime(String forecastTime) {
    this.forecastTime = forecastTime;
}

最后发现是maven里面配置了这个才导致这个错误：

    <!--<groupId>org.springframework</groupId> -->
    <!--<artifactId>spring-jdbc</artifactId> -->
    <!--<version>${org.springframework-version}</version> -->
    <!--</dependency> -->
