我想在测试方法事务中做一些数据库操作。我想为此使用junit TestRules。但是规则是在事务之外执行的。有没有办法让我的规则在交易中执行?
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:/META-INF/spring/applicationContext.xml"})
public class ProductServiceTest extends AbstractTransactionalJUnit4SpringContextTests {
public @Rule @Autowired MySimpleSpringRule mySimpleSpringRule;
@Before
public void before() {
logger.debug("before");
}
@After
public void after() {
logger.debug("after");
}
@Test
public void testFindProducts() {
...
和
@Component
public class MySimpleSpringRule implements TestRule {
private class Banaani extends ExternalResource {
@Override
protected void before() throws Throwable {
logger.debug("before");
};
@Override
protected void after() {
logger.debug("after");
};
}
private final Banaani banaani = new Banaani();
@Override
public Statement apply(Statement st, Description desc) {
return banaani.apply(st, desc);
}
结果是
2013-01-18 10:33:24,845 DEBUG [main]: MySimpleSpringRule - before
2013-01-18 10:33:24,869 INFO [main]: ionalTestExecutionListener - Began transaction (1): transaction manager [org.springframework.orm.jpa.JpaTransactionManager@a713a5]; rollback [true]

2013-01-18 10:33:24,987 DEBUG [main]: MySimpleSpringRule - after
直接在测试类中的@Before 和@After 方法在事务内部执行,而MySimpleSpringRule 中的方法在事务外部执行。
