InjectionServiceImp:

@Service

public class InjectionServiceImpl implements InjectionService {

@Autowired

private InjectionDAO injectionDAO;

public void save(String arg) {

System.out.println("service接收参数："+arg);

arg=arg+""+this.hashCode();

injectionDAO.save(arg);

}

InjectionDAOImpl:

@Repository

public class InjtctionDAOImpl implements InjectionDAO {

public void save(String arg) {

System.out.println("保存数据"+arg);

}

}

Test:

public class Test {

public static void main(String[] args) {

ClassPathXmlApplicationContext ctx=new ClassPathXmlApplicationContext("spring-inject.xml");

InjectionService service=(InjectionService)ctx.getBean("injectionServiceImpl");

service.save("这是要保存的数据");

}

这样还是会找不到bean怎么回事？
