准备

需要用到的东西如下，下载这几个项目最新的release版本:

1. Hibernate Core，这里用的版本为3.5.0-final

2. Hibernate Shards，这里用的版本为3.0.0-Beta2

3. MySql java connector，这里用的版本为5.1.12

4. slf4j，这里用的版本为1.5.11

5. 安装并启动mysql服务，在mysql中建立数据库hbshards，在里面如下建立测试用的contact表:

CREATE TABLE contact (

ID varchar(8) NOT NULL,

LOGIN_ID varchar(18) NOT NULL,

PASSWORD varchar(12) NOT NULL,

NAME varchar(40) NOT NULL,

EMAIL varchar(40) NOT NULL,

PRIMARY KEY (ID)

) ENGINE=InnoDB DEFAULT CHARSET=utf8

6. 设置好java环境变量

这里用于这个测试的CLASSPATH设置如下

.;

D:\Work\research\Java\Hibernate-Test\lib\antlr-2.7.6.jar;

D:\Work\research\Java\Hibernate-Test\lib\dom4j-1.6.1.jar;

D:\Work\research\Java\Hibernate-Test\lib\jta-1.1.jar;

D:\Work\research\Java\Hibernate-Test\lib\javassist-3.9.0.GA.jar;

D:\Work\research\Java\Hibernate-Test\lib\commons-collections-3.1.jar;

D:\Work\research\Java\Hibernate-Test\lib\slf4j-nop-1.5.11.jar;

D:\Work\research\Java\Hibernate-Test\lib\slf4j-api-1.5.11.jar;

D:\Work\research\Java\Hibernate-Test\lib\mysql-connector-java-5.1.12-bin.jar;

D:\Work\research\Java\Hibernate-Test\lib\hibernate3.jar;

Hibernate测试项目

用Eclipse建一个java项目Hibernate-Test，在项目文件夹下面建立lib目录

将hibernate3.jar放入lib目录中，把Hibernate发布包中lib\required目录下除了slf4j-api-1.5.8.jar之外的其他jar文件放入lib目录中

将mysql java connector发布包中的mysql-connector-java-5.1.12-bin.jar放入lib目录

将slf4j发布包中的slf4j-api-1.5.11.jar、slf4j-nop-1.5.11.jar放入lib目录

项目从lib目录中引用hibernate3.jar

在src目录下添加测试用的实体类ContactEntity:

public class ContactEntity {

private String _id;

private String _name;

private String _email;

private String _loginId;

private String _password;

public ContactEntity(){}

public ContactEntity(String id, String loginId, String password

,String name, String email){

this._id = id;

this._loginId = loginId;

this._password = password;

this._name = name;

this._email = email;

}

public String getId(){

return this._id;

}

public void setId(String id){

this._id=id;

}

public String getEMail(){

return this._email;

}

public void setEMail(String email){

this._email=email;

}

public String getName(){

return this._name;

}

public void setName(String name){

this._name=name;

}

public String getLoginId(){

return this._loginId;

}

public void setLoginId(String loginId){

this._loginId=loginId;

}

public String getPassword(){

return this._password;

}

public void setPassword(String password){

this._password=password;

}

public String toString(){

return "{ Id=\"" + this._id + "\""

+ ", LoginId=\"" + this._loginId + "\""

+ ", Name=\"" + this._name + "\""

+ ", EMail=\"" + this._email + "\" }";

}

}

测试实体的映射文件ContactEntity.hbm.xml:

项目结构如下图:

运行测试

用Eclipse编译class文件，将Main.class、ContactEntity.class以及hibernate.cfg.xml、ContactEntity.hbm.xml

拷贝到lib目录中，运行Main.class结果如下:
