Spring boot @未映射Spring引导控制器中特定实体的Id

我有两个实体

Employee

和

Department

，每个实体都有一个SpringWeb

@RestController

带更新方法的注释类，即

Http PUT

出于某种奇怪的原因（可能是一个非常明显的解决方案），每当为

Employee

类调用

PUT

时，JSON负载中的ID不会映射到

Employee

实体的

ID

类，但它对

部门

实体非常有效

员工

类别：

Entity
@Table(name = "EMPLOYEE")
public class Employee implements Serializable, Identity<Long>, Deleted
{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "NAME")
    private String name;

    @ManyToOne
    @Where(clause = "is_deleted = false")
    private Department department;

    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(name = "EMP_QUAL", joinColumns = @JoinColumn(name = "EMPLOYEE_ID"), inverseJoinColumns = @JoinColumn(name = "QUALIFICATION_ID"))
    @WhereJoinTable(clause = "IS_DELETED = false")
    @SQLDelete(sql = "UPDATE `EMP_QUAL` SET IS_DELETED = true where EMPLOYEE_ID = ? and QUALIFICATION_ID = ? and IS_DELETED = False")
    private Set<Qualification> qualifications;

    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(name = "EMP_PROJ", joinColumns = @JoinColumn(name = "emp_id"), inverseJoinColumns = @JoinColumn(name = "proj_id"))
    @Where(clause = "is_deleted = false")
    private Set<Project> projects;

    @JsonIgnore
    @Column(name = "is_deleted", nullable = false)
    private Boolean isDeleted = false;

    @Override
    public Long getId()
    {
        return this.id;
    }

    @Override
    public void setId(final Long id)
    {
        this.id = id;
    }

    public String getName()
    {
        return name;
    }

    public void setName(final String name)
    {
        this.name = name;
    }

    public Set<Project> getProjects()
    {
        return projects;
    }

    public void setProjects(final Set<Project> projects)
    {
        this.projects = projects;
    }

    public Department getDepartment()
    {
        return department;
    }

    public void setDepartment(final Department department)
    {
        this.department = department;
    }

    public Set<Qualification> getQualifications()
    {
        return qualifications;
    }

    public void setQualifications(final Set<Qualification> qualifications)
    {
        this.qualifications = qualifications;
    }

    public Boolean isDeleted()
    {
        return isDeleted;
    }

    public void setDeleted(final Boolean deleted)
    {
        isDeleted = deleted;
    }

}

@Entity
@Table(name = "DEPARTMENT")
public class Department implements Serializable, Identity<Long>, Deleted
{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

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

    @OneToMany(fetch = FetchType.EAGER)
    @WhereJoinTable(clause = "is_deleted = false")
    @JoinTable(name = "DEPARTMENT_EMPLOYEE", joinColumns = {@JoinColumn(name = "department_id")},
            inverseJoinColumns = {@JoinColumn(name = "employee_id")})
    @SQLDelete(sql = "UPDATE DEPARTMENT_EMPLOYEE SET is_deleted = true where department_id = ? and employee_id = ? and is_deleted = false")
    private Set<Employee> departmentMembers;

    @Column(name = "is_deleted", nullable = false)
    private Boolean isDeleted;

    @Override
    public Long getId()
    {
        return this.id;
    }

    @Override
    public void setId(final Long id)
    {
        this.id = id;
    }

    @Override
    public Boolean isDeleted()
    {
        return this.isDeleted;
    }

    @Override
    public void setDeleted(final Boolean isDeleted)
    {
        this.isDeleted = isDeleted;
    }

    public String getName()
    {
        return name;
    }

    public void setName(final String name)
    {
        this.name = name;
    }

    public Set<Employee> getDepartmentMembers()
    {
        return departmentMembers;
    }

    public void setDepartmentMembers(final Set<Employee> departmentMembers)
    {
        this.departmentMembers = departmentMembers;
    }
}

调用

PUT/employees/{id}

时：

调用

PUT/departments/{id}

：

正如您在调试器的屏幕截图中所看到的，

部门

的

id

字段被填充，而

员工

中该字段为空。我正在用Swagger进行测试，并在有效载荷中设置ID。我没有任何特定的Jackson配置集，我只是使用Spring boot的默认设置，但我无法理解为什么只有在Employee中，

id

字段从未映射

员工

身体：

{
"id":1,
  "name": "New Name"
}

{
"id":2,
  "name": "chemistry",
"deleted":false
}

部门

机构：

{
"id":1,
  "name": "New Name"
}

{
"id":2,
  "name": "chemistry",
"deleted":false
}

---

该问题是由于另一个与

员工

有关系的实体

项目

上的Jackson注释引起的：

@Entity
@Table(name = "PROJECT")
public class Project implements Serializable, Identity<Long>, Deleted
{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

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

    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(name = "EMP_PROJ", joinColumns = @JoinColumn(name = "proj_id"), inverseJoinColumns = @JoinColumn(name = "emp_id"))
    @JsonIdentityInfo(generator = ObjectIdGenerators.IntSequenceGenerator.class, property = "id")
    @Where(clause = "is_deleted = false")
    private Set<Employee> employees;

@实体
@表（name=“项目”）
公共类项目实现可序列化、标识、删除
{
@身份证
@GeneratedValue（策略=GenerationType.IDENTITY）
私人长id；
@列（name=“name”）
私有字符串名称；
@ManyToMany（fetch=FetchType.EAGER）
@JoinTable（name=“EMP\u PROJ”，joinColumns=@JoinColumn（name=“PROJ\u id”），inverseJoinColumns=@JoinColumn（name=“EMP\u id”））
@JsonIdentityInfo（generator=ObjectIdGenerators.IntSequenceGenerator.class，property=“id”）
@其中（子句=“已删除=错误”）
私人雇员；

您要传递给调用的主体是什么？@NiVeR使用主体数据更新。接口

删除的
和
标识
来自哪里？它们由我定义。它们只声明getter和setter，两个实体都实现它们
