1、首先徏立POJOc?br />
1
package org.apple.hibernate;
2
3
public class User {
4
private String id;
5 private String name;
6 private String password;
7
public String getId() {
8 return id;
9
}
10 public void setId(String id) {
11 this.id = id;
12 }
13 public String getName() {
14 return name;
15 }
16 public void setName(String name) {
17 this.name = name;
18 }
19 public String getPassword() {
20 return password;
21 }
22 public void setPassword(String password) {
23 this.password = password;
24 }
25
26
}
2、根据POJOc里面里面相关的字段写User.hbm.xml映射文gpackage org.apple.hibernate;2
3
public class User {
4
private String id;5
private String name;6
private String password;7
public String getId() {
8
return id;9
}10
public void setId(String id) {11
this.id = id;12
}13
public String getName() {14
return name;15
}16
public void setName(String name) {17
this.name = name;18
}19
public String getPassword() {20
return password;21
}22
public void setPassword(String password) {23
this.password = password;24
}25
26
} 1<?xml version="1.0" encoding="GB2312"?>

11 <property name="name"/>

3、徏?font style="background-color: #c7edcc">hibernate.cfg.xml<?xml version="1.0" encoding="GB2312"?>2

5、徏?font style="background-color: #c7edcc">UserTestc?br />

15 SchemaExport dbExport=new SchemaExport(conf);

PSQ要在mysql数据库里面先建立好usertest表，然后q行UserTestc，q样可以顺利通过hibernate3提供了自带的工具hbm2ddlQ徏立根据你的对象徏立数据库相关表?br /> 打开mysql数据库：
大功告成Q?br />

使用spring提供q个qo器就可以实现session的集中管理了Q所有以.dol尾的请求都自动分配?个session,q且在这个请求过E中都用这个session.
