spring 整合 hibernate:

  hibernate :对数据库交互

  spring: ioc   aop

  整合点:

    1.sessionFactory对象不再由hibernate生成,交由spring生成,也就是说数据库连接信息   全局配置   映射文件的配置  由spring完成

    2.ioc 管理dao对象  baseDao对象

    3.aop 事务的控制

  步骤:

    1.普通工程  copy jar 包

    2.配置applicationContext-resource.xml

        配置 sessionFactory  配置 dataSourse

        数据库连接配置   全局配置   映射文件的配置             属性名来自于底层属性,固定写法

    3.写po  及映射文件   以前怎么写的现在还是怎么写

    4.写dao      dao内必须有sessionFactory属性

    5.配置applicationContext-dao.xml

    6.测试即可

po:

public class Students {
  private Integer stuId;
  private String stuName;
  private String email;
  private Integer age;
  private Integer sex;
  private Integer cid;
  public Integer getStuId() {
    return stuId;
  }
  public void setStuId(Integer stuId) {
    this.stuId = stuId;
  }
  public String getStuName() {
    return stuName;
  }
  public void setStuName(String stuName) {
    this.stuName = stuName;
  }
  public String getEmail() {
    return email;
  }
  public void setEmail(String email) {
    this.email = email;
  }
  public Integer getAge() {
    return age;
  }
  public void setAge(Integer age) {
    this.age = age;
  }
  public Integer getSex() {
    return sex;
  }
  public void setSex(Integer sex) {
    this.sex = sex;
  }
  public Integer getCid() {
    return cid;
  }
  public void setCid(Integer cid) {
    this.cid = cid;
  }
}
