Ajax+Struts2+Spring+Hibernate整合

我们沿用Spring+Hibernate+DWR的例子，做一个Ajax+Struts2.0+Spring+Hibernate整合，许多步骤大体相似，
我就直接搬过来了：
首先，建一个web project,然后添加对hibernate和spring的支持，我们使用的是hibernate3.2和spring2.0,然后导入xwork-2.0.3.jar struts2-core-2.0.8.jar struts2-spring-plugin-2.0.8.jar ognl-2.6.11.jar freemarker-2.3.8.jar commons-logging-api-1.1.jar和commons-pool-1.3.jar(不知道myeclipse怎么搞的，添加Spring功能支持的时候就有了commons-dbcp.jar，居然没有其依赖的commons-pool-x.jar，只好单独添加了，另外，需要将Spring2.0 AOP Liberaries里的asm2.2.3.jar删除，因为好像和Hiberate中的生成代理用的asm.jar冲突，我把Spring2.0 AOP Liberaries排到最后仍然有冲突，所以只好删掉了，不知道大家遇到过这种情况么)。
我们使用myeclise自带的Derby数据库，在里面建一个表BOOK：
ID bigint primary key,autoincrement
NAME varchar(20)
ISBM varchar(20)
AUTHOR varchar(15)
然后利用myeclipse的hibernate反向工程生成领域模型：Book.java, DAO:BookDAO.jar, Book 的映射文件Book.hbm.xml：
生成的代码及配置文件如下:

Book.java:

packageedu.jlu.fuliang.domain;

/***//**
*BookgeneratedbyMyEclipsePersistenceTools
*/

publicclassBookimplementsjava.io.Serializable{

//Fields

privatelongid;
privateStringname;
privateStringisbm;
privateStringauthor;

//Constructors

/***//**defaultconstructor*/
publicBook(){
}

/***//**minimalconstructor*/
publicBook(Stringname,Stringisbm){
this.name=name;
this.isbm=isbm;
}

/***//**fullconstructor*/
publicBook(Stringname,Stringisbm,Stringauthor){
this.name=name;
this.isbm=isbm;
this.author=author;
}

//Propertyaccessors

publiclonggetId(){
returnthis.id;
}

publicvoidsetId(longid){
this.id=id;
}

publicStringgetName(){
returnthis.name;
}

publicvoidsetName(Stringname){
this.name=name;
}

publicStringgetIsbm(){
returnthis.isbm;
}

publicvoidsetIsbm(Stringisbm){
this.isbm=isbm;
}

publicStringgetAuthor(){
returnthis.author;
}

publicvoidsetAuthor(Stringauthor){
this.author=author;
}

}

BookDAO.java:

packageedu.jlu.fuliang.dao;

importjava.util.List;
importorg.apache.commons.logging.Log;
importorg.apache.commons.logging.LogFactory;
importorg.hibernate.LockMode;
importorg.springframework.context.ApplicationContext;
