SpringJUnit4ClassRunner does not close the Application Context at the end of JUnit test case
提问by rustyx
I'm using SpringJUnit4ClassRunner in my JUnit 4 tests like this:
我在 JUnit 4 测试中使用 SpringJUnit4ClassRunner，如下所示：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/test-context.xml"})
public class MyTest {
@Autowired
private ConfigurableApplicationContext context;
@Test
public void test1() {
. . .
}
@Test
public void test2() {
. . .
}
. . .
}
However, at the end of this test case the application context is not closed. I would like to have the application context closed at the end of the test case (NOT at the end of each individual unit-test in the test case).
但是，在此测试用例结束时，应用程序上下文并未关闭。我希望在测试用例结束时关闭应用程序上下文（而不是在测试用例中每个单独的单元测试结束时）。
So far I could come up with this work-around:
到目前为止，我可以想出这个解决方法：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/test-context.xml"})
public class MyTest {
@Autowired
private ConfigurableApplicationContext context;
private static ConfigurableApplicationContext lastContext;
@After
public void onTearDown() {
lastContext = context;
}
@AfterClass
public static void onClassTearDown() {
lastContext.close();
}
@Test
public void test1() {
. . .
}
@Test
public void test2() {
. . .
}
. . .
}
Is there a better solution?
有更好的解决方案吗？

You can add the @DirtiesContext(classMode=ClassMode.AFTER_CLASS)at the class level and the context will get closed once all the tests in the methods are done. You will get the same functionality as your current code.
您可以@DirtiesContext(classMode=ClassMode.AFTER_CLASS)在类级别添加 ，一旦方法中的所有测试完成，上下文就会关闭。您将获得与当前代码相同的功能。

How are you running your tests?
你如何运行你的测试？
Spring is not closing the context by default on test case close. Instead it install shutdown hook that is run when JVM exits. This obscure mechanism was introduces to allow test context caching, which is a good thing.
默认情况下，Spring 不会在测试用例关闭时关闭上下文。相反，它安装了在 JVM 退出时运行的关闭钩子。这种晦涩的机制被引入以允许测试上下文缓存，这是一件好事。
From my experience this works correctly when JUnit tests are run both from my IDE and from maven-surefire-plugin. Your solution is a bit of a hack and certainly should not be needed.
根据我的经验，当 JUnit 测试同时从我的 IDE 和maven-surefire-plugin. 您的解决方案有点麻烦，当然不需要。
