AbstractTransactionalJUnit4SpringContextTests

Question

我使用AbstractTransactionalJUnit4SpringContextTests作为我的测试类的超类。

但“mvn test”内存不足。

以下是我的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{

----

}

我错过了@Before @After或@BeforeClass @AfterClass这些测试真的很重的问题，因此我的内存不足了吗？

请帮忙！

谢谢！

这是堆栈跟踪：

Answer 1

您似乎通过ContextConfiguration批注将整个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。

Answer 2

堆栈跟踪是关于perm gen内存而不是堆。所以请尝试增加每代内存，例如-XX：MaxPermSize = 1024M
