为什么我的Spring Boot Rest数据应用程序中为HTTP路径映射了模糊的处理程序方法？

Question

到目前为止，我没有做过什么特别的事，但是这个令人讨厌的异常：

  

java.lang.IllegalStateException：为HTTP路径“http://localhost:8080/directoryWatches”映射的不明确的处理程序方法：{public org.springframework.http.ResponseEntity org.springframework.data.rest.webmvc.RepositoryEntityController.headCollectionResource（org.springframework） .data.rest.webmvc.RootResourceInformation，org.springframework.data.rest.webmvc.support.DefaultedPageable）抛出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.DefaultedPageable，org.springframework.data.domain.Sort，org.springframework.data.rest.webmvc。 PersistentEntityResourceAssembler）抛出org.springframework.data.rest.webmvc.ResourceNotFoundException，org.springframework.web.HttpRequestMethodNotSupportedException}

这是我的实体：

@Entity
public class DirectoryWatch {

@Id
@GeneratedValue
private long id;

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

我的DirectoryWatchRepository：

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

当我打开HAL浏览器并尝试打开NON-GET HTTP方法时，会发生异常：

我的pom文件的片段：

有没有人有帮助？

这可疑看起来像我报告的here Spring Framework 4.3 RC1中的回归。问题已经解决，即将推出的Spring Boot 1.4 M3将包含固定版本。

发布Boot应在几天内发布。在此之前，您可以手动升级到Spring Framework 4.3 RC2。
