</property> <property name="connection.useUnicode">true</property> <property name="connection.characterEncoding">UTF-8</property> <property name="hibernate.current_session_context_class">thread</property> <property name="show_sql">true</property> <property name="format_sql">true</property> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">123456</property> <property name="hibernate.hbm2ddl.auto">update</property> <mapping resource="com/main/News.hbm.xml"/> </session-factory> </hibernate-configuration>
News.hbm.xml文件内容:
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2015-7-27 16:52:17 by Hibernate Tools 3.4.0.CR1 --> <hibernate-mapping> <class name="com.main.News" table="NEWS"> <id name="id" type="int"> <column name="ID" /> <generator class="assigned" /> </id> <property name="title" type="java.lang.String"> <column name="TITLE" /> </property> <property name="content" type="java.lang.String"> <column name="CONTENT" /> </property> </class> </hibernate-mapping>
一个简单的insert操作:
Configuration conf = new Configuration().configure(); SessionFactory sf = conf.buildSessionFactory(); Session sess = sf.openSession(); Transaction tx = sess.beginTransaction(); News n = new News(); n.setId(11); n.setTitle("Title2"); n.setContent("Content2"); sess.save(n); n.setContent("editedContent"); tx.commit();
