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。
