hibernate - AbstractTransactionalJUnit4SpringContextTests

Question

我正在使用 AbstractTransactionalJUnit4SpringContextTests 作为我的测试类的父类(super class)。

但是“mvn test”内存不足。

这是我的 BaseTest 类的片段:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations=
    {"classpath:**/applicationContext.xml",
     "classpath:**/simple-test-datasource.xml"})
@TransactionConfiguration(
     transactionManager="myService.transactionManager",defaultRollback=true)
public class ServiceBaseTest extends AbstractTransactionalJUnit4SpringContextTests{

----

}

我是否缺少像 @Before @After 或 @BeforeClass @AfterClass 这样的测试真的很重，因此我的内存不足？

请帮忙!

谢谢!

这是堆栈跟踪:

您似乎正在通过 ContextConfiguration 注释将整个 Spring 应用程序上下文加载到内存中。这可能会占用大量内存，具体取决于您定义的 bean。

尝试通过在您的环境中设置 M2_OPTS=-Xmx256m 来增加 JVM 可用的内存。
