hibernate4在maven环境下使用hsqldb

 

1      简介

Hsqldb是一个开放源代码的JAVA数据库，其具有标准的SQL语法和JAVA接口，它可以自由使用和分发，非常简洁和快速的。

HSqlDB非常适合在用于快速的测试和演示的Java程序中。

2      配置maven的pom.xml文件

<dependency>                             <groupId>org.hibernate</groupId>                             <artifactId>hibernate-search-orm</artifactId>                             <version>4.4.2.Final</version>                    </dependency>                    <dependency>                             <groupId>org.hsqldb</groupId>                             <artifactId>hsqldb</artifactId>                             <version>2.3.0</version>                    </dependency>

 

3      启动数据库的mvn命令

Mvn exec:java  -Dexec.mainClass="org.hsqldb.Server" -Dexec.args="-database.0  file:target/data/tutorial"

 

4      启动数据库管理控制台的mvn命令

Mvn exec:java  -Dexec.mainClass="org.hsqldb.util.DatabaseManager"

 

5      Hibernate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>                    <!--  Database connection settings -->                    <property  name="connection.driver_class">org.hsqldb.jdbcDriver</property>                    <property  name="connection.url">jdbc:hsqldb:hsql://localhost</property>                    <property  name="connection.username">sa</property>                    <property  name="connection.password"></property>                     <!-- JDBC connection pool (use the  built-in) -->                    <property  name="connection.pool_size">1</property>                      <!--  SQL dialect -->                    <property  name="dialect">org.hibernate.dialect.HSQLDialect</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  class="fire.entity.Author" />                    <mapping  class="fire.entity.Book" />          </session-factory> </hibernate-configuration>

 

6      测试下是否可以使用

hibernate工具类：

import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration;   public class HibernateUtil {        private static final SessionFactory sessionFactory =  buildSessionFactory();        private static SessionFactory buildSessionFactory() {          try {             // Create the SessionFactory from  hibernate.cfg.xml             return new  Configuration().configure().buildSessionFactory();          }          catch (Throwable ex) {             // Make sure you log the  exception, as it might be swallowed             System.err.println("Initial  SessionFactory creation failed." + ex);             throw new  ExceptionInInitializerError(ex);          }      }        public static SessionFactory getSessionFactory() {          return sessionFactory;      }   }

 

Hibernate测试方法（java bean自己创建吧）：

public static void main(String[] args) {           Session session =  HibernateUtil.getSessionFactory().getCurrentSession();                                       session.beginTransaction(); //               SchemaExport  schemaExport = new SchemaExport(configuration); //               schemaExport.create(true,  true); //               Author  author = new Author(); //               author.setName("是的"); //               session.save(author);                    Query  query =  session.createQuery("from  Author");                    List<Author>  list = query.list();                    System.out.println(list.size());                                       session.getTransaction().commit();                             }
