dao层注解

@Repository("carDao")

Server层注解

@Service("userService")

@Transactional

自动注入

@Autowired

CarUserDao carUserDao;

控制层

@Controller("caruserAction")

public class CarUserAction extends ActionSupport {

@Autowired

private CarUserServicecarUserService;

Struts映射文件class改成事务管理的id(spring 自动注入自动实例化)

<actionname="user_*"class="userAction"
