Spring的jdbc:initialize-database标签使用

在使用spring的jdbc:initialize-database标签进行单元测试时,发现这个标签与dataSource一同使用时,SQL脚本没有被正确执行,测试过程如下:

applicationContext-jdbc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

	default-lazy-init="true">

	<!-- Jdbc单数据源事务 -->
	<bean id="transactionManager"

	</bean>

	<context:property-placeholder

          			  classpath*:/application.test.properties" />

	<!-- DBCP连接池-->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<property name="defaultAutoCommit" value="false" />
	</bean>
	 
	<jdbc:initialize-database data-source="dataSource"
			ignore-failures="ALL">
			<jdbc:script location="classpath:sql/h2/schema.sql" />
			<jdbc:script location="classpath:sql/h2/import-data.sql"
				encoding="UTF-8" />
		</jdbc:initialize-database>
	<!-- 
	<jdbc:embedded-database id="dataSource" type="H2">
		<jdbc:script location="classpath:sql/h2/schema.sql" />
		<jdbc:script location="classpath:sql/h2/import-data.sql"
			encoding="UTF-8" />
	</jdbc:embedded-database>
	 -->
</beans>

?java测试代码为:

package com.shagri.showcase.data;

import org.junit.Assert;
import org.junit.Test;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;

@ContextConfiguration("classpath:jdbc/applicationContext-jdbc.xml")
public class DataInitTest extends AbstractTransactionalJUnit4SpringContextTests {
	@Test
	public void testData(){
		Assert.assertEquals(6,countRowsInTable("ss_user"));
	}
}

? ? ?这里的import-data.sql和schema.sql是从springside4里面取出来的两个文件,在import-data.sql对ss_user表有6个insert语句。所以这里单元测试的期望是表中数据条数为6,但是遗憾的是,这里的测试失败,实际得到的数据条数为0。

? ? ?但是如果将xml文件中的dataSource和jdbc:initialize-database注释掉,而启用jdbc:embedded-database标记时,单元测试结果正确 。

? ? ?想与各位探讨一下这两种使用方式的不同之处,以及为什么会出现这样的问题。
