Question

我尝试从一个简单的spring数据休息应用程序开始，并努力解决多个OneToMany关系。我有一个人有很多项目和许多地址。要启动并运行应用程序，我必须在项目和地址中设置@RestResource注释以创建正确的链接。但遗憾的是链接不起作用（我得到一个空的结果），为什么我不能在person实体中设置@RestResource注释。这是我的代码。我希望你能帮助我。

人：

@Entity
public class Person implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    private int id;

    private String name;

    //bi-directional many-to-one association to Item
    @OneToMany
    @JoinColumn(name="id")
    private List<Item> items;

    //bi-directional many-to-one association to Address
    @OneToMany
    @JoinColumn(name="id")
    private List<Address> addresses;

    public Person() {
    }
// getter setter

地址

@Entity
public class Address implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    private int id;

    private String address;

    //bi-directional many-to-one association to Person
    @ManyToOne
    @JoinColumn(name="person_id")
    @RestResource(rel="address", path="address",exported=true)
    private Person person;

    public Address() {
    }

// getter setter

项目

@Entity
    @Table(name="items")
    public class Item implements Serializable {
        private static final long serialVersionUID = 1L;

        @Id
        private int id;

        @Column(name="item_name")
        private String itemName;

        //bi-directional many-to-one association to Person
        @ManyToOne
        @JoinColumn(name="person_id")
        @RestResource(rel="item", path="item",exported=true)
        private Person person;

        public Item() {
        }
// getter setter

我得到了这个结果

{
  "name" : "dave",
  "items" : [ {
    "itemName" : "ite,m"
  } ],
  "addresses" : [ {
    "address" : "myaddress1"
  } ],
  "_links" : {
    "self" : {
      "href" : "http://localhost:8090/person/1"
    },
    "person" : {
      "href" : "http://localhost:8090/person/1"
    },
    "address" : {
      "href" : "http://localhost:8090/person/1/address"
    },
    "item" : {
      "href" : "http://localhost:8090/person/1/item"
    }
  }
}%
