自己扩展封装Hibernate模板DAO-之二单独使用(hibernate)

1.引入Hibernate3.6的jar包及必须依赖包及JPA包

2.引入haha.hibernate.jar 及commons-beanutils-1.8.3.jar,commons-lang-2.5.jar三个包,我已发布了http://download.csdn.net/user/Lijun7788

3.引入数据库驱动包

我这里选择了一个非常简单的表

UserRoles (id int ,name String)来做个测试,采用注解的方式

UserRoles.java文件如下:

package com.haha.bean;import java.io.Serializable;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;@Entitypublic class UserRoles implements Serializable {@Id@GeneratedValue(strategy=GenerationType.IDENTITY)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;}}

Hibernate.cfg.xml文件如下

<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-configuration PUBLIC          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools.                   --><hibernate-configuration><session-factory><property name="myeclipse.connection.profile">sql</property><property name="connection.url">jdbc:sqlserver://127.0.0.1:1433;databaseName=mybookshop</property><property name="connection.username">sa</property><property name="connection.password"></property><property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property><property name="dialect">org.hibernate.dialect.SQLServerDialect</property><property name="show_sql">true</property><mapping class="com.haha.bean.UserRoles" /></session-factory></hibernate-configuration>

UserRoleDao.java文件:

package com.haha.dao;import java.util.List;import com.haha.bean.UserRoles;import com.haha.hibernate.HibernateDao;public class UserRoleDao extends HibernateDao<UserRoles, Integer> {public List<UserRoles> findAll(){return getAll("id",true);}public void add(UserRoles role){save(role);}}

UserRoleTest.java文件:

package com.haha.test;import java.util.List;import com.haha.bean.UserRoles;import com.haha.dao.UserRoleDao;public class UserRoleTest {/** * @param args */public static void main(String[] args) {addTest();findAllTest();}private static void findAllTest() {List<UserRoles> list=new UserRoleDao().findAll();for(UserRoles r:list)System.out.println(r.getId()+"."+r.getName());}private static void addTest() {UserRoles role=new UserRoles();role.setName("经理");new UserRoleDao().add(role);}}

运行结果:

非常的简单
