Java 扩展通用控制器时发生Spring mvc错误

我有一个通用的基本控制器。以及扩展该通用控制器的控制器列表。我已经看到了一些可以扩展控制器的地方。但是我得到的

是由：java.lang.IllegalStateException:不明确映射

错误引起的

基本控制器：

public abstract class BaseController<O extends BaseDomain, OT extends BaseDto> {

    private AbstractService<O, OT> service;

    public BaseController(AbstractService<O, OT> service) {
        this.service = service;
    }

    @RequestMapping(value="/", method = RequestMethod.GET)
    public ResponseObject list() {
        return somework();
    }

    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public ResponseObject get(@PathParam("id") String id) {
        return somework();
    }

    @RequestMapping(value="/", method = RequestMethod.POST)
    public ResponseObject create(@Valid @RequestBody OT input, Errors errors) {
        return somework();
    }

    @RequestMapping(value = "/{id}", method = RequestMethod.PATCH)
    public ResponseObject update(@PathParam("id") String id, @Valid @RequestBody OT input, Errors errors) {
        return somework();
    }

    @RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
    public ResponseObject delete(@PathParam("id") String id) {
        return somework();
    }

}

@RestController("/apis")
public class ApiController extends BaseController<Api, ApiDto>{

    public ApiController(@Autowired ApiService apiService) {
        super(apiService);
    }
}

@RestController("/clusters")
public class ClusterController extends BaseController<Cluster, ClusterDto>{

    public ClusterController(@Autowired ClusterService clusterService) {
        super(clusterService);
    }
}

我使用的是spring 4.3.10.RELEASE。有人帮我修理吗？谢谢。

您可以尝试：

@RestController
@RequestMapping("/apis")

及

您可以尝试以下方法：

@RestController
@RequestMapping("/apis")

及

---

在两个子控制器中都有这样的映射：

    @RestController
    RequestMapping (value= "/clusters") 

---

在两个子控制器中都有这样的映射：

    @RestController
    RequestMapping (value= "/clusters") 

---

传递给@RestController的值定义了Spring应用程序上下文中该bean的逻辑名称，默认情况下，该名称是该类名的camelCase版本。

---

@RequestMapping也可以用于指定类上的url映射。

您确定发布了所有内容吗？因为看起来你有一个/apis@OgnjenMišić感谢您的答复。是的，我已经贴了everything@DeepakAgrawal尝试“@RestController”RequestMapping（value=“/clusters”）是否确实发布了所有内容？因为看起来你有一个/apis@OgnjenMišić感谢您的答复。是的，我已经贴了everything@DeepakAgrawal尝试“@RestController”请求映射（value=“/clusters”）
