我正在使用Spring Boot 1.5.7,Spring Data REST,Spring HATEOAS,Hibernate,Spring Validation,Swagger。
我通过Spring Data REST暴露了我的所有存储库。它工作得很好但是当我暴露一个嵌套的对象列表时我遇到了问题。
让我们看看这个例子:
@Entity
public class TicketBundle extends AbstractEntity {
@OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.LAZY,mappedBy="ticketBundle")
@OnDelete(action = OnDeleteAction.NO_ACTION)
private List<MovementTicketBundle> payments = new ArrayList<>();
这是我的运动超类
@Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type")
public class Movement extends AbstractEntity {
@Column(nullable = false)
protected String description;
这是TicketBundle
使用的特定类:
@Entity
@DiscriminatorValue(value = "ticketBundle")
public class MovementTicketBundle extends Movement {
private static final long serialVersionUID = 3949580014012377816L;
@ManyToOne(fetch = FetchType.LAZY)
TicketBundle ticketBundle;
我为每个bean设置了一个存储库:
@Transactional
@PreAuthorize("isAuthenticated()")
public interface MovementRepository extends PagingAndSortingRepository<Movement, Long> {
}
和 @Transactional @PreAuthorize( “isAuthenticated()”) public interface MovementTicketBundleRepository扩展了PagingAndSortingRepository { }
和
@Transactional
@PreAuthorize("isAuthenticated()")
public interface TicketBundleRepository extends PagingAndSortingRepository<TicketBundle, Long> {
}
在Swagger中,我看到了TicketBundle
:
我正在尝试使用应返回GET http://localhost:8080/api/v1/ticketBundles/1/payments
列表的端点MovementTicketBundle
。
相反,这是发生的事情:
curl -X GET --header 'Accept: application/hal+json' 'http://localhost:8080/api/v1/ticketBundles/1/payments'
响应代码:405 响应正文:没有内容 响应标题:
{
"allow": "POST",
"content-length": "0",
"date": "Fri, 13 Oct 2017 07:52:11 GMT",
"x-application-context": "application:prod",
"x-content-type-options": "nosniff",
"x-frame-options": "DENY",
"x-xss-protection": "1; mode=block",
"content-type": null
}
如果嵌套资源是一个bean,一切正常。问题出在我列出的时候。我错过了什么吗?你有什么建议来解决这个问题吗?我没有看到关于这个问题的其他问题。
