SpringMVC注解Ambiguous mapping错误

[不醒石]

构建spring+springmvc+mybatis+maven 项目时，遇到了一个问题，断断续续在网上查了好多天了，一直没有解决。 问题是关于springmvc注解的。启动时一直报controller里的方法冲突错误。具体内容如下：
错误信息：
严重: Context initialization failed

controller类：
@Controller
@RequestMapping(name = "/seckill")
public class SeckillController {
private static Logger logger = LoggerFactory.getLogger(SeckillController.class);

private SeckillService seckillService;

public SeckillService getSeckillService() {
return seckillService;
}

@Autowired
public void setSeckillService(SeckillService seckillService) {
this.seckillService = seckillService;
}

@RequestMapping(name = "/list", method = RequestMethod.GET)
public String list(Model model) {
List<Seckill> list = seckillService.getSeckillList();
model.addAttribute("list", list);
return "list";
}

@RequestMapping(name = "/{seckillId}/detail", method = RequestMethod.GET)
public String detail(@PathVariable("seckillId") Long seckillId, Model model) {
if (seckillId == null) {
return "list";
}
Seckill seckill = seckillService.getById(seckillId);
if (seckill == null) {
return "forword:/seckill/list";
}
model.addAttribute("seckill", seckill);
return "detail";
}
spring-web.xml配置：
<!-- 扫描web相关的bean -->
<context:component-scan base-package="org.buxingshi.seckill.controller"/>
<mvc:annotation-driven/>
<mvc:default-servlet-handler/>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>

问题的诡异之处在于，当我把controller中的detail方法注释之后，就没有问题了；一旦有多个方法，就会出现Ambiguous mapping错误。求大神帮忙看看是什么问题

[李德胜1995]

@RequestMapping注解问题，方法的请求路径冲突，好好检查一下。。。

[天真呗]

@RequestMapping注解中的属性name 改为 value试试

[南宫廿贰]

@RequestMapping注解，路径我一般都不写属性
