今天是spring的最后一節課，這節課老師講了spring與hibernate整合完成增刪改查的操作，這是很重要的一節課，這也是第一次真正的實現spring結合Hibernate和數據庫連接上，下面是這次課的過程實現：
首先是數據庫建表：采用Oracle數據庫，在Scott用戶里新建USERS表，
所用jar包:
實現源碼如下：
Users.java
[java] view plain
copy package?www.csdn.spring.hibernate.domain;????import?java.io.Serializable;??import?java.util.Date;????public?class?Users?implements?Serializable?{????????????????private?static?final?long?serialVersionUID?=?1L;????????private?Integer?id;??????private?String?name;??????private?Date?regTime;????????public?Users()?{??????????super();????????????????}????????public?Users(Integer?id,?String?name,?Date?regTime)?{??????????super();??????????this.id?=?id;??????????this.name?=?name;??????????this.regTime?=?regTime;??????}????????public?Integer?getId()?{??????????return?id;??????}????????public?void?setId(Integer?id)?{??????????this.id?=?id;??????}????????public?String?getName()?{??????????return?name;??????}????????public?void?setName(String?name)?{??????????this.name?=?name;??????}????????public?Date?getRegTime()?{??????????return?regTime;??????}????????public?void?setRegTime(Date?regTime)?{??????????this.regTime?=?regTime;??????}????????@Override??????public?String?toString()?{??????????return?"Users?[id="?+?id?+?",?name="?+?name?+?",?regTime="?+?regTime??????????????????+?"]";??????}????????}??

到此為止簡單的spring+Hibernate完成增刪改查就實現了，運行測試類UserTest.java后結果如下
