Hibernate5.0.4入门实例?一、创建一个java普通工程hibernate，建立一个lib文件夹并导入需要的jar文件并右击lib文件夹将导入的lib文件build?path，建立classpath,这样代码中才能连接导入的jar包二、创建包，然后在包下创建实体类News(也就是操作数据库的类)package com.study.hibernate;importjava.sql.Date;public class News {?private Integer id;?private String title;?private String author;?private Date date;?public Integer getId() {??return id;?}?public void setId(Integer id) {??this.id = id;?}?public String getTitle() {??return title;?}?public void setTitle(String title) {??this.title = title;?}?public String getAuthor() {??return author;?}?public void setAuthor(String author) {??this.author = author;?}?public Date getDate() {??return date;?}?public void setDate(Date date) {??this.date = date;?}?}然后建立建立相关的hibernate?XML Mapping?file文件News.hbm.xml?xml version=1.0?!DOCTYPE hibernate-mapping PUBLIC -//Hibernate/Hibernate Mapping DTD 3.0//EN/hibernate-mapping-3.0.dtd!-- Generated 2015-12-8 1:51:11 by Hibernate Tools 3.5.0.Final --hibernate-mapping??? class name=com.study.hibernate.News table=NEWS??????? id name=id type=java.lang.Integer??????????? column name=ID /??????????? generator class=native /??????? /id??????? property name=title type=java.lang.String??????????? column name=TITLE /??????? /property??????? property name=author type=java.lang.String??????????? column name=AUTHOR /??????? /property??????? property name=date type=java.sql.Date??????????? column name=DATE /??????? /property??? /class/hibernate-mapping三、建立hibernate?配置文件hibernate.cfg.xml，?xml version=1.0 encoding=UTF-8?!DOCTYPE hibernate-configuration PUBLIC??-//Hibernate/Hibernate Configuration DTD 3.0//EN??/dtd/hibernate-configuration-3.0.dtdhibernate-configuration??? session-factory??? ?!-- 配置连接数据库的基本信息 --??? ?property name=connection.usernameroot/property??? ?property name=connection.passwordkxf3099/property??? ?property name=connection.driver_classcom.mysql.jdbc.Driver/property??? ?property name=connection.urljdbc:mysql://localhost:3306/hibernate/property??? ???? ?!-- 配置hibernate的基本信息 --??? ?!-- hiberna
