使用Spring和Hibernate在内存db中使用DbUnit H2
作者:互联网
嗨,我正在尝试使用JPA和单元测试进行一点POC来验证是否已创建数据库模式.我正在使用H2 DB并且我设置为Hibernate从实体创建模式,但是当DbUnit尝试从数据集初始化DB时,我总是得到一个表…在tableMap中找不到.我读到我必须将属性DB_CLOSE_DELAY = -1添加到DB URL,但就像Hibernate创建模式一样,当DbUnit尝试初始化时DB丢失了.
有任何想法吗?任何帮助都非常感谢.
这是我的配置:
应用程序的context.xml
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSourceH2" />
<property name="packagesToScan" value="com.xxx.model" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="generateDdl" value="true" />
<property name="showSql" value="true" />
<!-- property name="databasePlatform" value="org.hibernate.dialect.MySQLInnoDBDialect" /-->
<property name="databasePlatform" value="org.hibernate.dialect.H2Dialect" />
<!-- property name="database" value="MYSQL" /-->
</bean>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">create</prop>
<prop key="javax.persistence.validation.mode">CALLBACK</prop>
</props>
</property>
</bean>
<bean id="dataSourceH2"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.h2.Driver" />
<property name="url" value="jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1" />
<property name="username" value="sa" />
<property name="password" value="" />
</bean>
RepositoryTest.java
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/application-context-test.xml" })
@Transactional
public class SystemEntityRepositoryH2Test {
@Inject
private SystemEntityRepository repository;
@Inject
private DataSource dataSourceH2;
private IDatabaseConnection connection;
@Before
public void setUp() throws Exception {
IDatabaseConnection dbUnitCon = null;
dbUnitCon = new DatabaseDataSourceConnection(dataSourceH2, "testdb");
dbUnitCon.getConfig().setProperty(DatabaseConfig.FEATURE_QUALIFIED_TABLE_NAMES, true);
IDataSet dataSet = this.getDataSet("dataset-systementity.xml");
DatabaseOperation.INSERT.execute(dbUnitCon, dataSet);
}
@After
public void tearDown() throws Exception {
//DatabaseOperation.DELETE_ALL.execute(this.getConnection(), this.getDataSet(dataSetFile));
}
@Test
public void test() throws Exception {
}
protected IDataSet getDataSet(String dataSetFile) throws Exception {
ResourceLoader resourceLoader = new ClassRelativeResourceLoader(this.getClass());
Resource resource = resourceLoader.getResource(dataSetFile);
if (resource.exists()) {
return new FlatXmlDataSetBuilder().build(resource.getInputStream());
}
return null;
}
}
数据集,systementity.xml
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<System_Entities id="2" name="NAME" phone01="+52-55-55555555" email="a@a.com"
address01="Street" address02="123" address03="1" address04="Address04"
address05="Address05" city="City" state="State" country="MX"
zipcode="12345" />
</dataset>
错误
ERROR DatabaseDataSet:286 - Table 'System_Entities' not found in tableMap=org.dbunit.dataset.OrderedTableNameMap[_tableNames=[], _tableMap={}, _caseSensitiveTableNames=false]
我可以看到这些表是由hibernate创建的,因为日志显示所有sql语句而没有错误.
谢谢.
解
谢谢Mark Robinson
我将setUp方法修改为:
@Before
public void setUp() throws Exception {
IDatabaseConnection dbUnitCon = null;
EntityManager entityManager = entityManagerFactory.createEntityManager();
Session session = entityManager.unwrap(Session.class);
SessionImplementor si = (SessionImplementor) session;
Connection conn = si.getJdbcConnectionAccess().obtainConnection();
dbUnitCon = new DatabaseConnection(conn);
//dbUnitCon.getConfig().setProperty(DatabaseConfig.FEATURE_QUALIFIED_TABLE_NAMES, true);
IDataSet dataSet = this.getDataSet("dataset-systementity.xml");
DatabaseOperation.INSERT.execute(dbUnitCon, dataSet);
}
它现在有效,我还不明白的是,如果我使用HSQLDB,我没有这个问题.
解决方法:
问题是DBUnit在Hibernate初始化之前加载表数据.
作为@setup的一部分,您需要获得Hibernate会话.这应该会导致Hibernate创建你的表.你甚至可以通过执行像select 1这样的简单查询来强制它
