Struts2+Spring4+myBatis3整合
终于开始整合了，三大工具各司其职。Struts负责与jsp交互，Spring针对javaBean的生命周期进行管理，myBatis负责数据库部分。
个人认为整合最重要的是找对相应的包，不然包之间就可能出现冲突，然后一直报错。以下是千辛万苦测试成功的包：

Action注解单例问题
交有spring管理后，action默认是单例模式。但是项目不能全部都采用单例，使用我们需要加入相关注解切换为非单例：
在action上面配置，@Scope("prototype") ，每个请求都会new一个新的实例

public class UserAction extends ActionSupport {
/**

private static final long serialVersionUID = 1L;
@Autowired
//@Resource(name="userservice")

private User user=new User();//不写New,将报空指针

this.user = user;

Bean注解管理
Spring自动扫描管理Bean注解有四种配置模式，如下
@Service 用于业务层(service) 示例：@Service("baseService")
@Controller 用于控制层(action) 示例：@Controller("baseAction")
@Repository 用于数据访问层(dao) 示例：@Repository("baseDao")
@Component 泛型配置(当组件不确定时用)，以上3种配置是基于此扩展
*/
/*
@Service自动装配到Spring的容器，为其他组件提供服务；
通过@Transactional进行事务的管理；
通过@Resource注入UserDao对象。
