Question

I have a maven spring project (latest version) and I want to write some junit tests (latest version).

The issue I have is that my spring beans are autowired, and when I call them from junit test, I get null pointer exceptions, as spring doesn’t autowire them.

How can I load the context so that things are autowired?

Have you studied Testing chapter in Spring reference documentation? Here is an example you should start with:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class MyTest {

    @Resource
    private FooService fooService;

    // class body...
}

If you are in com.example.MyTest in /src/test/java, you will need /src/test/resources/com/example/MyTest-context.xml – but the exceptions will show you the way.
