Spring 4.x 中可以为子类注入子类对应的泛型类型的成员变量的引用
项目结构：
BaseRepository.java
public class BaseRepository<T> { }
BaseService.java
public class BaseService<T>{ @Autowired protected BaseRepository<T> repository; public void add(){ System.out.println("add..."); System.out.println(repository); } }
User.java
public class User { }
UserRepository.java
@Repository public class UserRepository extends BaseRepository<User>{ }
UserService.java
@Service public class UserService extends BaseService<User>{ }
Test.java
public class Test { public static void main(String[] args) { ApplicationContext context=new ClassPathXmlApplicationContext("bean-gi.xml"); UserService service=(UserService) context.getBean("userService"); service.add(); } }
