具有关联关系的实体的Spring数据休息状态500
作者：互联网
我有两个实体,一对多
public class Order {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
private String userName;
private String company;
@OneToMany(cascade={CascadeType.PERSIST, CascadeType.MERGE})
@JoinColumn(name="ORDER_ID")
private List<Item> items;
}
public class Item {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
private String name;
private Long quantity;
}
这两个实体都有一个@RepositoryRestResrouce,当我尝试在/ orders集合中发布具有以下项的新Order时：
{
"userName":"Marco",
"company":"MP",
"items":[
{"name":"CD","quantity":"10"},
{"name":"DVD","quantity":"5"}
]
}
我有一个内部服务器错误：

我知道我可以使用关联资源,但是我想知道如何在一个POST中创建带有商品的订单.
解决方法:
仅add parameter个已导出= false到项目存储库中的@RepositoryRestResrouce批注.然后,您可以在一个请求中创建带有物料的订单：
{
"userName": "Marco",
"company": "MP",
"items": [
{
"name": "CD",
"quantity": "10"
},
{
"name": "DVD",
"quantity": "5"
}
]
}
我建议您向订单中的项目添加cascade = CascadeType.ALL,orphanRemoval = true,以使项目完全由Order管理.
附加info.
如果要独立使用“订单”和“项目”,则可以保留所有内容,但要先创建项目：
POST http://localhost:8080/items
{
{
"name": "CD",
"quantity": "10"
},
{
"name": "DVD",
"quantity": "5"
}
}
然后创建包含它们的订单：
POST http://localhost:8080/orders
{
{
"userName": "Marco",
"company": "MP",
"items": [
"http://localhost:8080/items/1",
"http://localhost:8080/items/2"
]
}
}
您对项目使用@JoinColumn批注-因此,在这种情况下,我认为您必须在Order和Items之间实现synchronization.
而且请不要在一行中发布JSON))
