为什么我的Spring Boot Rest Data Application中为HTTP路径映射了模糊的处理程序方法？

Question

到目前为止，我还没有做任何特别的事情，但是有一个令人讨厌的异常：

java.lang.IllegalStateException：为HTTP路径' http：// localhost：8080 / directoryWatches映射的模糊处理程序方法：{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，公共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）引发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...
}

而我的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：

有没有人有帮助的想法？

这看起来像是我在这里报告的Spring Framework 4.3 RC1中的回归。 该问题已得到解决，即将发布的Spring Boot 1.4 M3将包含已修复的版本。

发行版Boot应该会在几天之内可用。 在此之前，您可以手动升级到Spring Framework 4.3 RC2。
