SpringJUnit4ClassRunner与声明性和带注释的bean

Question

I have a declarative spring config

@Configuration
public class SpringConfig {
   @Bean 
   public someBean() {
      return new Bean1();
   }
}

and a @Component annotated Bean

@Component
public class Bean2 {   
}

Now I would like to use both of then in my UnitTest

@RunWith(SpringJUnit4ClassRunner.class)
public void UnitTest {
   @Autowired Bean1 bean1;

   @Autowired Bean2 bean2;
}

but I have no idea how to do it.

Answer 1

You can do this:

@ContextConfiguration(classes = {SpringConfig.class})
@RunWith(SpringJUnit4ClassRunner.class)
public void UnitTest {
   @Autowired Bean1 bean1;

   @Autowired Bean2 bean2;
}

For class Bean2, you can add the @ComponentScan annotation:

@Configuration
@ComponentScan("com....package.of.bean2")
public class SpringConfig {
   @Bean 
   public someBean() {
      return new Bean1();
   }
}

If you don't want to add the ComponentScan to your SpringConfig class, you can add an additional test config class with the ComponentScan annotation and add it to the ContextConfiguration annotation:

@ContextConfiguration(classes = {SpringConfig.class, SpringTestConfig.class})
