这是我写的测试代码：
package com.towset.sshdlib.util;

import org.hibernate.Session;
import org.hibernate.Transaction;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.towset.sshdlib.business.IEleBookService;
import com.towset.sshdlib.business.service.EleBookImp;
import com.towset.sshdlib.business.IBookMarkService;
import com.towset.sshdlib.business.service.BookMarkImp;
import com.towset.sshdlib.business.IBorrowInfoService;
import com.towset.sshdlib.business.service.BorrowInfoImp;

import com.towset.sshdlib.model.BookConern;
import com.towset.sshdlib.model.BookMark;
import com.towset.sshdlib.model.BorrowBookInfo;
import com.towset.sshdlib.model.ElectionBook;
import com.towset.sshdlib.model.UserInfo;

public class Test {
IEleBookService service;
  EleBookImp ebi;
//  IBookMarkService ibmark;
//  BookMarkImp bmark;
//  IBorrowInfoService ibinfo;
//  BorrowInfoImp binfo;

  ElectionBook eb = new ElectionBook();
  BookConern bc = new BookConern();
  UserInfo ui=new UserInfo();
  BookMark bm=new BookMark();
  BorrowBookInfo bbi=new BorrowBookInfo();


  public void save(){
    ApplicationContext context =
     new ClassPathXmlApplicationContext(new String[]{"daoBean.xml","serviceBean.xml"});

//    ApplicationContext context=
//      new ClassPathXmlApplicationContext("bean.xml");

//    ebi=(EleBookImp)context.getBean("ieleBookService");

    service=(IEleBookService)context.getBean("ieleBookService");


//    Session se = HibernateUtil.currentSession();
//    Transaction tx = se.beginTransaction();

    bc.setCname("renyou");
    bc.setCisbn("345");
    bc.setCtel("1357");
    bc.setCaddress("shanghai");
    bc.setCremark("haode");

   eb.setEthesis("zero");
    eb.setEresponsible("wang");
   eb.setEisbn("12423");
    eb.setEurl("d:/TowSet");
   eb.setEsort("kexue");
    eb.setEclegree(2);
    eb.setEremark("chenggong");
    eb.setBconern(bc);

    System.out.println("bao");
//    se.save(eb);
//    tx.commit();
//    HibernateUtil.closeSession();

//    ebi.createObject(eb);
    service.createObject(eb);
  }

  public ElectionBook getEleBookByIsbn(Long isbn){
    ApplicationContext context= new ClassPathXmlApplicationContext(new String[]{"daoBean.xml","serviceBean.xml"});
    ebi=(EleBookImp)context.getBean("eleBookService");
    return eb=ebi.findById(isbn);
  }

  public void deleteElebook(String isbn){
    ApplicationContext context= new ClassPathXmlApplicationContext(new String[]{"daoBean.xml","serviceBean.xml"});
    ebi=(EleBookImp)context.getBean("eleBookService");
    ebi.deleteObject(isbn);
  }

  public static void main(String[] args) {
    // TODO 自动生成方法存根
    Test te = new Test();
    te.save();

  }

}
