无法从 START_ARRAY 令牌中反序列化 `java.lang.String` 实例

Question

`当我调用 api 并删除超过 1 个建筑物时，它不起作用。但是当我删除 1 栋建筑时，就可以了。我认为我的 json 错误，请帮我修复它

我尝试搜索，但没有看到任何想法。

这是我的 json 代码： $('#btnDeleteBuilding').click(函数 (e) {

e.preventDefault(); var buildingIds=$('#tableList').find('tbody input[type=checkbox]:checked').map(function(){ return $(this).val(); }).get(); deleteBuildings(buildingIds); });

函数deleteBuildings(buildingID) { 变量数据 = {}; 如果

(buildingID == null){ buildingID = $("#listForm").find('tbody input[type=checkbox]:checked').map(function () { return $(this).val(); }).get().join(",");

} 数据['id'] = 建筑物ID;

$.ajax({ url: "${buildingAPI}", type: "DELETE",

数据：JSON.stringify（数据）， dataType: "json",

contentType: "application/json", success: function (response) {

console.log("成功") }, 错误：函数（响应）{ console.log("失败"); 控制台.log（响应）`` },` });

}`

这是我的函数删除：`

    @Transactional
    public void deleteBuilding(Long[] id) {`
        for(Long item:id){
            List<RentAreaEntity> list=rentAreaRepository.findByBuildingId(item);`
            for(RentAreaEntity item1:list){
                rentAreaRepository.deleteById(item1.getId());
            }
           ` List<AssignmentBuildingEntity> list1=as`signmentBuildingRepository.findAll();
            list1.forEach(it->{if (it.getId().equals(id)){ assignmentBuildingRepository.deleteById(it.getId());
            }
            });
           ` buildingRepository.deleteById(item);``
        }
    }
My Entity:
`
@Entity
@Table(name="rentarea")
public class RentAreaEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    @ManyToOne
    @JoinColumn(name="buildingid")
    private BuildingEntity building;

    @Column(name="value")
    private Long value;

    public BuildingEntity getBuilding() {
        return building;
    }
    public void setBuilding(BuildingEntity building) {
        this.building = building;
    }

    @Column(name="createddate")
    private Date createddate;

    @Column(name="modifieddate")
    private Date modifieddate;

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

    public Date getCreateddate() {
        return createddate;
    }

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

    public Long getId() {
        return id;
    }

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

    public Long getValue() {
        return value;
    }

    public void setValue(Long value) {
        this.value = value;
    }

    public Date createddate() {
        return createddate;
    }

    public void setCreateddate(Date createddate) {
        this.createddate = createddate;
    }

    public Date getModifieddate() {
        return modifieddate;
    }

    public void setModifieddate(Date modifieddate) {
        this.modifieddate = modifieddate;
    }

    public String getCreatedby() {
        return createdby;
    }

    public void setCreatedby(String createdby) {
        this.createdby = createdby;
    }

    public String getModifiedby() {
        return modifiedby;
    }

    public void setModifiedby(String modifiedby) {
        this.modifiedby = modifiedby;
    }


}

My json:
function deleteBuildings(buildingID) {
        var data = {};
        if(buildingID == null){
            buildingID = $("#listForm").find('tbody input[type=checkbox]:checked').map(function () {
                return $(this).val();
            }).get().join(",");
        }
        data['id'] = buildingID;
        $.ajax({
            url: "${buildingAPI}",
            type: "DELETE",
            data: JSON.stringify(data),
            dataType: "json",
            contentType: "application/json",
            success: function (response) {
                console.log("success")
            },
            error: function (response) {
                console.log("fail");
                console.log(response)
            },
        });
        window.location.href = "<c:url value='/admin/building-list?message-success'/>";
    }
