hibernate映射文件注解

新建一个model类并带有注解

import javax.persistence.Column;  
import javax.persistence.Entity;  
import javax.persistence.GeneratedValue;  
import javax.persistence.Id;  
import javax.persistence.Table;  
  
import org.hibernate.annotations.GenericGenerator;  
  
@Entity//表示为实体类  
@Table(name="test_user")//表名注解  
public class User {  
    private Integer id;  
    private String userName;  
    private String passWorld;  
    private String userNick;  
    private Integer enable;  
      
    @Id//表示主键  
    @GenericGenerator(name = "generator", strategy = "increment")  
    @GeneratedValue(generator = "generator")// 自增长  
    @Column(name = "id")// 类属性对应着表字段  
    public Integer getId() {  
        return id;  
    }  
      
    public void setId(Integer id) {  
        this.id = id;  
    }  
      
    @Column(name = "user_name")  
    public String getUserName() {  
        return userName;  
    }  
      
    public void setUserName(String userName) {  
        this.userName = userName;  
    }  
      
    @Column(name = "pass_world")  
    public String getPassWorld() {  
        return passWorld;  
    }  
      
    public void setPassWorld(String passWorld) {  
        this.passWorld = passWorld;  
    }  
      
    @Column(name = "user_nick")  
    public String getUserNick() {  
        return userNick;  
    }  
      
    public void setUserNick(String userNick) {  
        this.userNick = userNick;  
    }  
      
    @Column(name = "enable")  
    public Integer getEnable() {  
        return enable;  
    }  
      
    public void setEnable(Integer enable) {  
        this.enable = enable;  
    }  
}

　　在hibernate的session工厂中添加一个属性：

<property name="packagesToScan">  
        <list>  
                <value>com.haier.hibernate.model</value>  
        </list>  
</property>

即自动扫描路径。

开发时使用这个model即可。
