java - Spring Boot变量重命名问题(Hibernate)

Question

我在实体类中的变量名称是assignTo和assignBy，上面在MySQL db中的列名称是assignto和分别分配。

但是项目正在通过名称“assignmentTo”和“assignmentBy”创建它。

删除 .m2/repository 文件夹后，我已删除整个数据库并使用 mvn clean install 重新创建。

Postman 仍在 GET API 上返回“assignmentTo”和“assignmentBy”。

使用“assignTo”和“assignBy”名称调用 POST 方法，但仍然得到“assignmentTo”和“assignmentBy”。

类LeadAssignment:

@Entity
@Table(name = "lead_assignment")
public class LeadAssignment {

        @Id
        @GeneratedValue(strategy = javax.persistence.GenerationType.IDENTITY )
        @Column(name = "laid", nullable = false, updatable = false)
        private Long id;

        @Column(name = "first_name", nullable = false)
        private String firstname;

        @Column(name = "last_name", nullable = false)
        private String lastname;

        @Column(name = "assignto" , nullable = false)
        private String assignTo;

        @Column(name = "assignby", nullable = false)
        private String assignBy;

        @Column(name = "requirement" , nullable = false)
        private String requirements;

        @Column(name = "remark" , nullable = false)
        private String remarks;

Controller 类LeadAssignmentController:

预期的 postman 输出:

  {
        "id": 1,
        "remarks": "demo3",
        "demanderRentLeadStatus": null,
        "demanderBuyLeadStatus": null,
        "supplierSellLeadStatus": null,
        "supplierRentLeadStatus": null,
        "sales": null,
        "lastname": "foo",
        "firstname": "bar",
        "assignTo": "david",
        "assignBy": "james",
        "requirements": "for rent out"
    }

postman 的实际输出:

{
    "id": 1,
    "remarks": "demo3",
    "demanderRentLeadStatus": null,
    "demanderBuyLeadStatus": null,
    "supplierSellLeadStatus": null,
    "supplierRentLeadStatus": null,
    "sales": null,
    "lastName": null,
    "firstName": null,
    "assignmentTo": null,
    "assignmentBy": null,
    "requirments": null
}

Answer 1

重命名类的 getter 和 setter。使它像: assignTo 的 getter 和 setter 分别是 getAssignTo() 和 setAssignTo(String s)。对 assignBy 执行相同的操作。
