最近在学习hibernate5，经历了比较痛苦的入门，踩了不少坑。好在，结果还是搞出了自己的hello hibernate.
开发环境：eclipse+jdk8 hibernate JAR包：hibernate-release-5.2.5.Final
MySQL表脚本 CREATE TABLE `person` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(20) CHARACTER SET gb2312 NOT NULL, `password` varchar(20) NOT NULL, `sex` varchar(2) CHARACTER SET gb2312 DEFAULT NULL, `email` varchar(30) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=13 DEFAULT CHARSET=latin1; 数据模型 Person.java Note:每个属性都要有getter, setter package hiber; public class Person { private String id ; private String name ; private String password ; private String sex ; private String email ; public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public String toString(){ return getId() + ":" + getName() +":" + getEmail() +":" + getSex() +":"; } } 数据模型与表字段mapping，person.hbm.xml Note: generator要注意，这里踩了不少坑。 参考：http://ryxxlong.iteye.com/blog/612446 http://blog.csdn.net/huaweitman/article/details/39025553 <?xml version="1.0" encoding='UTF-8'?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" > <!-- DO NOT EDIT: This is a generated file that is synchronized --> <!-- by MyEclipse Hibernate tool integration. --> <!-- Created Thu Nov 09 16:06:12 CST 2006 --> <hibernate-mapping package="hiber"> <class name="Person" table="PERSON"> <id name="id" column="ID" type="string"> <generator ***class="native"*** /> </id> <property name="name" column="NAME" type="string" not-null="true" /> <property name="password" column="PASSWORD" type="string" not-null="true" /> <property name="sex" column="SEX" type="string" /> <property name="email" column="EMAIL" type="string" /> </class> </hibernate-mapping> hibernate.cfg.xml配置 Note：记得把mysql驱动JAR加入编译路径； <?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">mysql</property> <property name="connection.url">jdbc:mysql://localhost:3306/test</property> <property name="connection.username">root</property> <property name="connection.password">test</property> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <property name="show_sql">true</property> **<mapping resource="person.hbm.xml" />** </session-factory> </hibernate-configuration> 数据操作类 PersonOperate.java package hiber; import java.util.List; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; import org.hibernate.query.Query; public class PersonOperate { private Session session = null; public PersonOperate(){ //get hibernate config Configuration configuration = new Configuration().configure(); // get sessionFactory SessionFactory factory = configuration.buildSessionFactory(); // get a ssesion this.session = factory.openSession(); } public void insert(Person person){ Transaction transaction = this.session.beginTransaction(); this.session.save(person); transaction.commit(); // this.session.close(); } public List<Person> query(){ List<Person> persons = null; @SuppressWarnings("unchecked") Query<Person> query = this.session.createQuery("FROM Person"); persons = query.getResultList(); return persons; } } 测试类 Test.java package hiber; import java.util.List; public class test { public static void main(String[] args){ PersonOperate operate = new PersonOperate(); for(int i=1; i<11; i++){ Person person = new Person(); person.setEmail("danny.yao@13.com"); // person.setId(""); //db 自增主键 person.setName("danny"+i); person.setPassword("pwd"); person.setSex("m"); operate.insert(person); } List<Person> persons; persons = operate.query(); System.out.println(persons.size()); for(Person person : persons){ System.out.println(person.toString()); } } }
