测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { config.ConcertConfig.class })
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class ObjectAServiceImplTest { 
    @Autowired
    private ObjectAService obaService;

    @Autowired
    private ObjectBService obbService;

    @Test
    public void testSupportMethod() throws Exception {
        System.out.println("==== TEST A ====");
        obaService.save(new ObjectA());
        obaService.update(new ObjectA());
        obaService.delete(10L);

        System.out.println("==== TEST B ====");
        obbService.save(new ObjectB());
        obbService.update(new ObjectB());
        obbService.delete(20L);
    }
}

测试结果

==== TEST A ====
save(), class entity.ObjectA
save()
update(), class entity.ObjectA
update()
delete(), 10
delete()
==== TEST B ====
save(), class entity.ObjectB
save()
update(), class entity.ObjectB
update()
delete(), 20
delete()

说明

_ Spring AOP 无法找到父类方法，所以要在定位方法的时候，定位到父类方法 _
