java – 从单元测试中启动和停止hsqldb

2019-07-22 02:03:41 作者：互联网

我正在尝试在内存模式下使用hsqldb创建集成测试.目前,我必须在运行单元测试之前从命令行启动hsqldb服务器.我希望能够从我的集成测试中控制hsqldb服务器.我似乎无法从代码中得到这一切.

更新：

这似乎与在类路径中有一个hibernate.cfg.xml文件一起工作：

org.hsqldb.Server.main(new String[]{});

在我的hibernate.cfg.xml文件中：

<property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="connection.url">jdbc:hsqldb:mem:ww</property>
<property name="connection.username">sa</property>
<property name="connection.password"></property>
<property name="connection.pool_size">1</property>
<property name="dialect">org.hibernate.dialect.HSQLDialect</property>
<property name="current_session_context_class">thread</property>
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<property name="hbm2ddl.auto">update</property>

更新
看来,使用jUnit和内置测试运行器从Eclipse中运行单元测试时,这只是一个问题.如果我跑

 mvn test

它们被正确执行,没有例外.就依赖性而言,我是否遗漏了一些东西？我使用了生成eclipse项目

mvn eclipse:eclipse

而我的pom是：

更新
好吧,不知道这里究竟出了什么问题,但我似乎已经修好了.我删除了HSQLDB创建的所有文件,以及我的Maven目标文件夹中的所有创建文件,使用maven做了一个干净的,重新创建的eclipse .project并在eclipse中刷新了项目.我想我可能已经从之前的配置中遗留了一些东西而已经将其抛弃了.

谢谢大家的帮助！

解决方法:

我使用以下配置(直接受到Hibernate tutorial的启发)没有任何问题：

<hibernate-configuration>
  <session-factory>

    <!-- Database connection settings -->
    <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>
    <property name="hibernate.connection.url" value="jdbc:hsqldb:mem:foobar"/>
    <property name="hibernate.connection.username" value="sa"/>
    <property name="hibernate.connection.password" value=""/>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">1</property>

    <!-- SQL dialect -->
    <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>

    <!-- 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.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="hibernate.hbm2ddl.auto" value="update"/>

    <mapping resource="..."/>

  </session-factory>
</hibernate-configuration>

使用内存中的HSQLDB时,无需显式启动任何内容.只需使用mem：protocol,内存数据库将从JDBC开始.
