目标：将Student实体对象加入数据库
1、首先需要下载三个东西：hibernate，slf4j，mysql。
2、分别取他们的包导入新建的项目中，我这里的版本是：hibernate-release-5.2.10里面lib目录下的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(建议直接去文档复制然后改)
<?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中创建student表，字段：id age name
5、创建自己的实体类在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、在对应package即student下配置文件：Student.hbm.xml
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="student"> <class name="Student" table="student"> <id name="id" column="id"> </id> <property name="name" type="string" column="name"/> <property name="age" type="int" column="age"/> </class> </hibernate-mapping>
7、创建测试类：StudentText.java
package student;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class StudentText {
public static void main(String[] args) {
Student stu = new Student();
stu.setId(4);
stu.setName("小明");
stu.setAge(12);
Configuration con = new Configuration();
SessionFactory sf = con.configure().buildSessionFactory();
Session s = sf.openSession();
s.beginTransaction();
s.save(stu);
s.getTransaction().commit();
s.close();
sf.close();
}
}
输出结果，完成：
