Spring boot @ResponseBody不序列化实体id
Spring boot @ResponseBody不序列化实体id
提问于 2014-07-19 19:12:30
有一个奇怪的问题，不知道如何处理它。拥有简单的POJO：
@Entity
@Table(name = "persons")
public class Person {
@Id
@GeneratedValue
private Long id;
@Column(name = "first_name")
private String firstName;
@Column(name = "middle_name")
private String middleName;
@Column(name = "last_name")
private String lastName;
@Column(name = "comment")
private String comment;
@Column(name = "created")
private Date created;
@Column(name = "updated")
private Date updated;
@PrePersist
protected void onCreate() {
created = new Date();
}
@PreUpdate
protected void onUpdate() {
updated = new Date();
}
@Valid
@OrderBy("id")
@OneToMany(mappedBy = "person", fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval = true)
private List<PhoneNumber> phoneNumbers = new ArrayList<>();
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getMiddleName() {
return middleName;
}
public void setMiddleName(String middleName) {
this.middleName = middleName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getComment() {
return comment;
}
public void setComment(String comment) {
this.comment = comment;
}
public Date getCreated() {
return created;
}
public Date getUpdated() {
return updated;
}
public List<PhoneNumber> getPhoneNumbers() {
return phoneNumbers;
}
public void addPhoneNumber(PhoneNumber number) {
number.setPerson(this);
phoneNumbers.add(number);
}
@Override
public String toString() {
return ToStringBuilder.reflectionToString(this, ToStringStyle.SHORT_PREFIX_STYLE);
}
}
@Entity
@Table(name = "phone_numbers")
public class PhoneNumber {
public PhoneNumber() {}
public PhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
@Id
@GeneratedValue
private Long id;
@Column(name = "phone_number")
private String phoneNumber;
@ManyToOne
@JoinColumn(name = "person_id")
private Person person;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
@Override
public String toString() {
return ToStringBuilder.reflectionToString(this, ToStringStyle.SHORT_PREFIX_STYLE);
}
}和rest端点：
@ResponseBody
@RequestMapping(method = RequestMethod.GET)
public List<Person> listPersons() {
return personService.findAll();
}在json响应中，除了Id之外的所有字段，我需要在前端编辑/删除person。如何将spring boot配置为序列化Id？
这就是响应现在的样子：
[{
"firstName": "Just",
"middleName": "Test",
"lastName": "Name",
"comment": "Just a comment",
"created": 1405774380410,
"updated": null,
"phoneNumbers": [{
"phoneNumber": "74575754757"
}, {
"phoneNumber": "575757547"
}, {
"phoneNumber": "57547547547"
}]
}]UPD有双向hibernate映射，可能与问题有关。

我最近也遇到了同样的问题，因为这就是spring-boot-starter-data-rest默认的工作方式。请参阅my my SO question -> While using Spring Data Rest after migrating an app to Spring Boot, I have observed that entity properties with @Id are no longer marshalled to JSON
要自定义它的行为方式，可以扩展RepositoryRestConfigurerAdapter以公开特定类的ID。
import org.springframework.context.annotation.Configuration;
import org.springframework.data.rest.core.config.RepositoryRestConfiguration;
import org.springframework.data.rest.webmvc.config.RepositoryRestConfigurerAdapter;
@Configuration
public class RepositoryConfig extends RepositoryRestConfigurerAdapter {
@Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(Person.class);
}

来自@eric-peladan的答案不是开箱即用的，但非常接近，也许这适用于Spring Boot的以前版本。现在它应该是这样配置的，如果我错了，请纠正我：
import org.springframework.context.annotation.Configuration;
import org.springframework.data.rest.core.config.RepositoryRestConfiguration;
import org.springframework.data.rest.webmvc.config.RepositoryRestConfigurerAdapter;
@Configuration
public class RepositoryConfiguration extends RepositoryRestConfigurerAdapter {
@Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(User.class);
config.exposeIdsFor(Comment.class);
}

从3.1开始，类RepositoryRestConfigurerAdapter已被弃用，请直接实现RepositoryRestConfigurer。
@Configuration
public class RepositoryConfiguration implements RepositoryRestConfigurer {
@Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.exposeIdsFor(YouClass.class);
RepositoryRestConfigurer.super.configureRepositoryRestConfiguration(config);
}
}
