我是靠谱客的博主 美丽羊,最近开发中收集的这篇文章主要介绍一个简单的SH例子,觉得挺不错的,现在分享给大家,希望可以做个参考。

概述

测试


package tarena.test;

import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import tarena.dao.BookDao;
import tarena.domain.Book;

public class BookDaoTest {

public static void main(String[] args) {
ApplicationContext txt = new ClassPathXmlApplicationContext("applicationContext.xml");
BookDao dao = (BookDao) txt.getBean("bookDao");

Book book = new Book("struts core",560);
// book.setId(1);
//dao.save(book);
// dao.update(book);

System.out.println( dao.findById(1).getName());
// dao.delete(3);
List list = dao.findByPrice(10, 3000);
for (Object object : list) {
Book b = (Book)object;
System.out.println(b.getId()+":"+b.getName()+":"+b.getPrice());
}
}
}

<constructor-arg ref="ht"/>
</bean>

</beans>



接口的实现类

package tarena.dao.hb;

import java.util.List;

import org.springframework.orm.hibernate3.HibernateTemplate;

import tarena.dao.BookDao;
import tarena.domain.Book;

public class BookDaoImpl implements BookDao {

private HibernateTemplate ht;
public BookDaoImpl(HibernateTemplate ht) {
super();
this.ht = ht;
}

public void delete(int id) {
Book b = findById(id);
ht.delete(b);
}

public Book findById(int id) {
return (Book)ht.get(Book.class,id);
}

public List findByPrice(double from, double to) {
String hql="from Book b where b.price between ? and ?";
return ht.find(hql, new Double[]{from,to});
}

public void save(Book book) {
ht.save(book);
}

public void update(Book book) {
ht.update(book);
}

}



dao接口

package tarena.dao;

import java.util.List;

import tarena.domain.Book;

public interface BookDao {

void save(Book book);

void update(Book book);

void delete(int id);

Book findById(int id);

List findByPrice(double from, double to);
}



hibernate的映射文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping>
<class name="tarena.domain.Book" table="laz_book" catalog="openlab">
<id name="id">
<generator class="native"></generator>
</id>
<property name="name">
<column name="name" length="32"></column>
</property>
<property name="price">
<column name="price" length="25"></column>
</property>
</class>
</hibernate-mapping>


pojo类

package tarena.domain;

public class Book {

private int id;
private String name;
private double price;


public Book() {
super();
}
public Book(String name, double price) {
super();
this.name = name;
this.price = price;
}
public Book(int id, String name, double price) {
super();
this.id = id;
this.name = name;
this.price = price;
}
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;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
}
