重拾Hibernate(1)之环境配置

1、新建Web Project工程

2、导入所需jar包

3、Student.java

[java]
package com.itmyhome;

import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name="T_STUDENT")
public class Student extends BizEntity{
    private String name;
    private String score;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getScore() {
        return score;
    }
    public void setScore(String score) {
        this.score = score;
    }

}

package com.itmyhome;

import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name="T_STUDENT")
public class Student extends BizEntity{
private String name;
private String score;
public String getName() {
  return name;
}
public void setName(String name) {
  this.name = name;
}
public String getScore() {
  return score;
}
public void setScore(String score) {
  this.score = score;
}

}

Teacher.java

[java]
package com.itmyhome;

import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name="T_TEACHER")
public class Teacher extends BizEntity{
    private String name;
    private String title;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }

}

package com.itmyhome;

import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name="T_TEACHER")
public class Teacher extends BizEntity{
private String name;
private String title;
public String getName() {
  return name;
}
public void setName(String name) {
  this.name = name;
}
public String getTitle() {
  return title;
}
public void setTitle(String title) {
  this.title = title;
}

}

BizEntity.java

[java]
package com.itmyhome;

import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import org.hibernate.annotations.GenericGenerator;

public class BizEntity {
    private String id;

    @Id @GeneratedValue(strategy=GenerationType.AUTO,generator="bizGenerator")
    @GenericGenerator(strategy = "uuid", name = "bizGenerator")
    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }




}

package com.itmyhome;

import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import org.hibernate.annotations.GenericGenerator;

public class BizEntity {
private String id;

@Id @GeneratedValue(strategy=GenerationType.AUTO,generator="bizGenerator")
@GenericGenerator(strategy = "uuid", name = "bizGenerator")
public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

}

BizEntity.java是所有实体类的父类，id自动生成策略为uuid

4、hibernate.hbm.xml

[html]
<?xml version="1.0"?>

        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
