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;
}
}
