How to access Spring context in jUnit tests annota

2019-01-16 15:35发布

I have following test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/services-test-config.xml"})
public class MySericeTest {

  @Autowired
  MyService service;
...

}

Is it possible to access services-test-config.xml programmatically in one of such methods? Like:

ApplicationContext ctx = somehowGetContext();

This works fine too:

@Autowired
ApplicationContext context;

If your test class extends the Spring JUnit classes
(e.g., AbstractTransactionalJUnit4SpringContextTests or any other class that extends AbstractSpringContextTests), you can access the app context by calling the getContext() method.
Check out the javadocs for the package org.springframework.test.

It's possible to inject instance of ApplicationContext class by using SpringClassRule and SpringMethodRule rules. It might be very handy if you would like to use another non-Spring runners. Here's an example:

@ContextConfiguration(classes = BeanConfiguration.class)
public static class SpringRuleUsage {

    @ClassRule
    public static final SpringClassRule springClassRule = new SpringClassRule();

    @Rule
    public final SpringMethodRule springMethodRule = new SpringMethodRule();

    @Autowired
    private ApplicationContext context;

    @Test
    public void shouldInjectContext() {
    }
}

Since the tests will be instantiated like a Spring bean too, you just need to implement the ApplicationContextAware interface:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/services-test-config.xml"})
public class MySericeTest implements ApplicationContextAware
{

  @Autowired
  MyService service;
...
    @Override
    public void setApplicationContext(ApplicationContext context)
            throws BeansException
    {
        // Do something with the context here
    }
}
