  • spring 整合 hibernate xml配置

    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;
      }
    }
