整合hibernate和spring这样的文章已经很多了,下面我们来看看如何利用myeclipse的功能为整合提速咯

package  mapping;

public   class  Test  {

     public  Test()  {
         super ();
         //  TODO Auto-generated constructor stub
    }

     private   int  id;
    
     private  String name;

     public   int  getId()  {
         return  id;
    }

     public   void  setId( int  id)  {
         this .id  =  id;
    }

     public  String getName()  {
         return  name;
    }

     public   void  setName(String name)  {
         this .name  =  name;
    }
    
    
}

<? 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  default-lazy ="false"   auto-import ="true"  package ="mapping" >
    < class  table ="test"  name ="Test" >
      < id  name ="id"  column ="test_id"  type ="int" >
        < generator  class ="native" ></ generator >
      </ id >
     
      < property  name ="name"  type ="string"  column ="name" ></ property >
    </ class >
</ hibernate-mapping >

然后开发对应的DAO操作pojo, 因为我比较懒,所以直接使用HibernateTemplate进行操作

package mapping;
 
import java.util.List;

import org.hibernate.Criteria;
import org.springframework.orm.hibernate3.HibernateTemplate;

public class TestDAO {

    private HibernateTemplate hibernateTemplate;

    public TestDAO() {
        super();
        // TODO Auto-generated constructor stub
    }

    public Test getTest(String name) throws Exception {
        Test t=new Test();
        t.setName(name);
        List list = this.getHibernateTemplate().findByExample(t);
        if (list.isEmpty())
            throw new Exception("No Such Record");
        else
            return (Test) list.get(0);
    }

    public void addTest(String name) {
        Test test = new Test();
        test.setName(name);
        this.getHibernateTemplate().save(test);
    }

    public void updateTest(Test test){
        this.getHibernateTemplate().update(test);
    }
    
    public void deleteTest(Test test){
        this.getHibernateTemplate().delete(test);
    }
    
    public HibernateTemplate getHibernateTemplate() {
        return hibernateTemplate;
    }

    public void setHibernateTemplate(HibernateTemplate ht) {
        this.hibernateTemplate = ht;
    }
}

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

最后的最后,开发一个测试类:

import mapping.Test;
import mapping.TestDAO; 
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class Tester {
 
    public static void main(String args[]) {
        ApplicationContext ctx = new FileSystemXmlApplicationContext(
                "src/applicationContext.xml");
        TestDAO test = (TestDAO) ctx.getBean("testDAO");
        //test.addTest("dyerac");
        try { 
            Test t = test.getTest("bsbs");
            System.err.println(t.getName());
            //t.setName("bsbs");
            //test.updateTest(t);
             //test.deleteTest(t);
        } catch (Exception e) { 
            System.err.println(e);
        }
    }
}
