目標：將Student實體對象加入數據庫
1、首先需要下載三個東西：hibernate，slf4j，mysql。
2、分別取他們的包導入新建的項目中，我這里的版本是：hibernate-release-5.2.10里面lib目錄下的required中的全部文件 slf4j-1.7.25下的受slf4j-nop-1.7.25.jar mysql的mysql-connector-java-5.1.42-bin.jar
3、在src下配置hibernate.cfg.xml(建議直接去文檔復制然后改)

<?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><!-- Database connection settings --><property name="connection.driver_class">com.mysql.jdbc.Driver</property><property name="connection.url">jdbc:mysql://localhost/text02</property><property name="connection.username">root</property><property name="connection.password">6530033197</property><!-- JDBC connection pool (use the built-in) --><!--<property name="connection.pool_size">1</property>--><!-- SQL dialect --><property name="dialect">org.hibernate.dialect.MySQLDialect</property><!-- Enable Hibernate's automatic session context management --><!-- <property name="current_session_context_class">thread</property> --><!-- Disable the second-level cache --><property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property><!-- Echo all executed SQL to stdout --><property name="show_sql">true</property><!-- Drop and re-create the database schema on startup --><!--<property name="hbm2ddl.auto">update</property>--><mapping resource="student/Student.hbm.xml"/></session-factory></hibernate-configuration> |
4、在mysql中創建student表，字段：id age name
5、創建自己的實體類在src下建包student，然后建Class：Student.java

package student;public class Student {private int id;private int age;private String name;public int getId() {return id;}public void setId(int id) {this.id = id;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getName() {return name;}public void setName(String name) {this.name = name;}public Student(int id, int age, String name) {super();this.id = id;this.age = age;this.name = name;}public Student() {// TODO Auto-generated constructor stub}} |
6、在對應package即student下配置文件：Student.hbm.xml

7、創建測試類：StudentText.java

輸出結果，完成：
