爲什麼我在Spring Boot Rest Data Application中爲HTTP路徑映射了模糊的處理程序方法？

Question

我並沒有做什麼特別的到現在爲止，但得到這個惱人的例外：

java.lang.IllegalStateException：映射爲HTTP路徑「http://localhost:8080/directoryWatches」不明確的處理方法：{公共org.springframework.http.ResponseEntity組織。 springframework.data.rest.webmvc.RepositoryEntityController.headCollectionResource（org.springframework.data.rest.webmvc.RootResourceInformation，org.springframework.data.rest.webmvc.support.DefaultedPageable）throws org.springframework.web.HttpRequestMethodNotSupportedException，public org。 springframework.hateoas.Resources org.springframework.data.rest.webmvc.RepositoryEntityController.getCollectionResource（org.springframework.data.rest.webmvc.RootResourceInformation，org.springframework.data.rest.webmvc.support.DefaultedPa geable，org.springframework.data.domain.Sort，org.springframework.data.rest.webmvc.PersistentEntityResourceAssembler）拋出org.springframework.data.rest.webmvc.ResourceNotFoundException，org.springframework.web.HttpRequestMethodNotSupportedException}

這裏是我的實體：

@Entity 
public class DirectoryWatch { 

@Id 
@GeneratedValue 
private long id; 

@Column(unique = true) 
private String name; 
//setters, getters and default constructor... 
} 

而且我DirectoryWatchRepository：

@RepositoryRestResource 
public interface DirectoryWatchRepository extends PagingAndSortingRepository<DirectoryWatch, Long> { 
} 

發生異常時，當我打開瀏覽器HAL並嘗試打開NON-GET HTTP中號編制方法：

片斷我POM文件：

有沒有人伸出援助的想法？

這個可疑看起來像Spring框架4.3 RC1的迴歸，我已經報here。問題已經解決，即將推出的Spring Boot 1.4 M3將包含固定版本。

發佈引導應該在幾天內可用。在此之前，您可以手動升級到Spring Framework 4.3 RC2。
