这篇“Hibernate使用的方法是什么”文章的知识点大部分人都不太理解，所以小编给大家总结了以下内容，内容详细，步骤清晰，具有一定的借鉴价值，希望大家阅读完这篇文章能有所收获，下面我们一起来看看这篇“Hibernate使用的方法是什么”文章吧。
1.引入框架依赖
计算
安全
数据库
网络和加速
企业服务

用于数据库的连接配置代替了之前的util中的连接类。
创建后引入dtd约束
复制这一段等会放入到核心配置文件中
hibernate.cfg.xml(核心配置文件)
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration>
<session-factory>
<!-- 数据库相关配置 -->
<!-- connection.username|connection.password|connection.url|connection.driver_class|dialect -->
<!-- 连接数据库账户名称 -->
<property name="connection.username">root</property>
<!-- 连接数据库密码(我的数据库没有登录密码，直接不用写) -->
<property name="connection.password">123</property>
<!-- 连接的绝对路径(使用&需要解译&) -->
<property name="connection.url">
jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=UTF-8&userSSL=false </property>
<!-- 驱动的绝对路径 -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<!-- 数据库方言配置 -->
<property name="dialect">
org.hibernate.dialect.MySQLDialect </property>
<!-- 配置本地事务 -->
<property name="hibernate.current_session_context_class">thread</property>
<!-- 调试相关配置 -->
<!-- hibernate运行过程是否展示sql命令代码(自动生成) -->
<property name="show_sql">true</property>
<!-- 是否规范输出sql代码 -->
<property name="format_sql">true</property>
<!-- 实体映射相关配置 -->
<mapping resource="com/liyingdong/entity/User.hbm.xml"/>
</session-factory></hibernate-configuration>子配置文件
对应的你是实体类，有多少个实体对应多少个子配置文件。
注意要在配置文件中引入dtd约束
复制到配置文件中
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!-- 实体类映射文件 -->
<hibernate-mapping>
<!--
name:实体类全路径名
table:实体类对于的数据库表名称
-->
<class name="com.liyingdong.entity.User" table="t_user_hb">
<!--
id:用于设置数据库表结构中主键列的生成方式
name:实体类中属性名称
type:Jave的数据类型
column:数据库表字段名称
-->
<id name="id" type="java.lang.Integer" column="id">
<!--
class:定义主键列生成的方式:hibernate管理、数据库管理、开发者管理

-->
<generator class="increment"></generator>
</id>
<!-- 与实体类相匹配 -->
<property name="userName" type="java.lang.String" column="user_name"/>
<property name="userPwd" type="java.lang.String" column="user_pwd"/>
<property name="realName" type="java.lang.String" column="real_name"/>
<property name="sex" type="" column="sex"/>
<property name="birthday" type="java.util.Date" column="birthday"/>
<property name="createdatetime" insert="false" update="false" type="timestamp" column="create_datetime"/>
<property name="remark" type="java.lang.String" column="remark"/>
</class>
</hibernate-mapping>实体类
package com.liyingdong.entity;import java.io.Serializable;import java.sql.Timestamp;import java.util.Date;public class User implements Serializable{ private Integer id; private String userName; private String userPwd; private String realName; private String sex; private Date birthday; private Timestamp createdatetime; private String remark; public Integer getId() { return id;
