测试在Eclipse中单独工作(右键单击,以Junit身份运行),但是当我使用maven从命令行运行它们时,它会在尝试获取与HSQL数据库的DataSource连接时停止.

LogicalConnectionImpl [DEBUG] Obtaining JDBC connection

对我来说最奇怪的部分是,如果我将测试限制为10(不是类,而是单独的@Test方法),它将起作用.但是,一旦进行了第11次测试,就会爆炸.测试组合没关系,所以如果我有30个测试,并且我选择运行11个或更多,那么它将失败.这让我觉得它是一个DataSource连接最大问题,但到目前为止还没有运气细节.我已经尝试添加堆大小只是为了咯咯笑,但这不起作用.

因此,在此挂起之前,我有多个成功的JDBC连接和发布.

这是我的applicationContext-HSQL.xml,它用于Eclipse和Command Line版本.我知道b / c我通过弄乱下面的Class值强迫他们每个人失败.

我的所有Test类都使用Spring 3.2.5,JPA,DBUnit并扩展AbstractInMemoryTests.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:applicationContext-hsqldb.xml"})
public class AbstractInMemoryTests {

private static final String FLAT_XML_DATASET = "FlatXmlDataSet.xml";

@Autowired
BasicDataSource bds;

@Before
public void setUp() throws Exception {
    DatabaseOperation.CLEAN_INSERT.execute(getConnection(), getDataSet());
}

@SuppressWarnings("deprecation")
private IDataSet getDataSet() throws Exception {
    InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream(FLAT_XML_DATASET);
    IDataSet dataset = new FlatXmlDataSet(inputStream);
    return dataset;
}

private IDatabaseConnection getConnection() throws Exception {
    Connection jdbcConnection = bds.getConnection();
    IDatabaseConnection connection = new DatabaseConnection(jdbcConnection);
    return connection;
}
}

关于为什么我可能会挂在那个连接上的任何想法,或者关于如何排除故障的想法？

谢谢,

解决方法:

根据通常的协议,良好的夜间睡眠可以帮助您思考.我完全覆盖了我的DataSource的appContext-hsqldb.xml属性的maxActive设置

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="org.hsqldb.jdbcDriver" />
    <property name="url" value="jdbc:hsqldb:mem:test" />
    <property name="username" value="sa" />
    <property name="password" value="" />
    ****<property name="maxActive" value="-1"/>****
</bean>

希望这有助于将来的其他人.
