一、准备
1. Hibernate: hibernate-distribution-3.3.2.GA, hibernate-annotations-3.4.0.GA
2. Spring: spring-framework-2.5.5-with-dependencies.zip
3. Struts2: struts-2.1.6-all.zip
4. Extjs: ext-3.0.0.zip
另外,数据库使用Oracle XE,开发工具使用eclipse-jee-galileo-SR1-win32,Web容器使用apache-tomcat-6.0.14。
二、数据库建表
新建表空间DEMO,新建用户demo、密码demo。在该表空间中建表HSSEA_DEMO和OBJECT_ID,OBJECT_ID用于存储主键值。
(
ID NUMBER ( 10 ) NOT NULL ,
CODE NVARCHAR2( 200 ) NOT NULL ,
DESCRIPTION NVARCHAR2( 200 )
);
ALTER TABLE HSSEA_DEMO ADD (
CONSTRAINT HSSEA_DEMO_PK
PRIMARY KEY
(ID));
CREATE TABLE OBJECT_ID
(
NAME VARCHAR2 ( 255 BYTE) NOT NULL ,
VALUE NUMBER ( 10 ) NOT NULL
);
三、新建动态网站
Project name : HSSEADemo。Target runtime单击New...,弹出框选择Apache Tomcat v6.0,Next,Tomcat installation directory选择安装tomcat的根目录,Finish。再一次Finish完成新建动态网站。
四、整合Hibernate、Spring
复制以下jar包到项目WebContent\lib下
hibernate-distribution-3.3.2.GA\hibernate3.jar
hibernate-distribution-3.3.2.GA\lib\required目录下所有jar包
hibernate-distribution-3.3.2.GA\lib\optional\c3p0\c3p0-0.9.1.jar
hibernate-annotations-3.4.0.GA\hibernate-annotations.jar
hibernate-annotations-3.4.0.GA\lib目录下的hibernate-commons-annotations.jar、ejb3-persistence.jar
hibernate-annotations-3.4.0.GA\lib\test目录下log4j.jar、slf4j-log4j12.jar
spring-framework-2.5.5\dist\spring.jar
spring-framework-2.5.5\lib\aspectj下所有包
其他还需引入包commons-logging-1.0.4.jar,ojdbc14.jar。
在项目Properties->Java Build Path->Libraries,Add JARs... 加入所有包。

增加Demo实体类
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;

pkColumnName = " NAME " ,
valueColumnName = " VALUE " ,
pkColumnValue = " HSSEA_DEMO_PK " ,
initialValue = 1 ,
allocationSize = 1

@SequenceGenerator(name = " hssea_demo_seq " , sequenceName = " seq_hssea_demo " , allocationSize = 1 )

@Column(name = " CODE " )

@Column(name = " DESCRIPTION " )

}
public void setCode(String code) {
this .code = code;
}
public String getDescription() {

}
public void setDescription(String description) {

}
}
增加DemoService类
import java.util.HashSet;
import java.util.List;
import java.util.Set;
import org.hibernate.criterion.Criterion;
import org.hibernate.criterion.Restrictions;
import org.springframework.stereotype.Service;

List < Demo > list = super .query(set);
if (list != null && list.size() > 0 ){
return list.get( 0 );
} else {
return null ;
}
}
}
DemoService中只需关注特殊业务,基本增删改查已由BaseServiceForHibernate完成。
在src下增加目录config,并增加四个如下配置文件:

增加log4j配置,在src目录下增加commons-logging.properties和log4j.properties
commons-logging.properties
org.apache.commons.logging.Log = org.apache.commons.logging.impl.Log4JLogger
log4j.properties
log4j.rootCategory = ERROR,stdout

log4j.logger.com.xy.service.BaseServiceForHibernate = DEBUG
增加单元测试
项目Properties->Java Build Path->Libraries,Add Library...,选择JUnit,JUnit4,Finish。
