我对使用 Spring 相当陌生。我了解自动装配的概念,但对实现感到困惑。我有一个 Maven 多模块项目,我正在尝试自动装配模块 A 中的管理器类,以便我可以在模块 B 中使用它。当我尝试运行 webapp 时,出现如下错误:
No matching bean of type [com..Manager] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
模块 A(jar):Manager.java
public interface Manager
{...}
ManagerImpl.java
@Service(value="manager")
public class ManagerImpl implements Manager
{...}
模块 B(战争):WebController.java
@Controller
public class WebController
{
@Autowired
private Manager manager;
..}
applicationContext.xml(在模块 A 中)
