準(zhǔn)備
需要用到的東西如下，下載這幾個(gè)項(xiàng)目最新的release版本:
1. Hibernate Core，這里用的版本為3.5.0-final
2. Hibernate Shards，這里用的版本為3.0.0-Beta2
3. MySql java connector，這里用的版本為5.1.12
4. slf4j，這里用的版本為1.5.11
5. 安裝并啟動(dòng)mysql服務(wù)，在mysql中建立數(shù)據(jù)庫(kù)hbshards，在里面如下建立測(cè)試用的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. 設(shè)置好java環(huán)境變量
這里用于這個(gè)測(cè)試的CLASSPATH設(shè)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測(cè)試項(xiàng)目
用Eclipse建一個(gè)java項(xiàng)目Hibernate-Test，在項(xiàng)目文件夾下面建立lib目錄
將hibernate3.jar放入lib目錄中，把Hibernate發(fā)布包中l(wèi)ib\required目錄下除了slf4j-api-1.5.8.jar之外的其他jar文件放入lib目錄中
將mysql java connector發(fā)布包中的mysql-connector-java-5.1.12-bin.jar放入lib目錄
將slf4j發(fā)布包中的slf4j-api-1.5.11.jar、slf4j-nop-1.5.11.jar放入lib目錄
項(xiàng)目從lib目錄中引用hibernate3.jar

在src目錄下添加測(cè)試用的實(shí)體類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 + "\" }";} } 測(cè)試實(shí)體的映射文件ContactEntity.hbm.xml: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping><class name="ContactEntity" table="CONTACT"><id name="Id" column="ID" ><generator class="assigned"/></id> <property name="EMail" column="EMAIL" /><property name="Name" column="NAME" /><property name="LoginId" column="LOGIN_ID" /><property name="Password" column="PASSWORD" /></class> </hibernate-mapping> 測(cè)試用的類: import java.util.Iterator; import java.util.List; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration;

運(yùn)行測(cè)試
用Eclipse編譯class文件，將Main.class、ContactEntity.class以及hibernate.cfg.xml、ContactEntity.hbm.xml 拷貝到lib目錄中，運(yùn)行Main.class結(jié)果如下:
