前端拿不到Long类型成员变量，用@JsonSerialize(using = ToStringSerializer.class)序列化一下

@EqualsAndHashCode(callSuper = true)
@Data
@TableName("la_school_business")
@Schema(description = "商务负责人表")
public class SchoolBusiness extends BaseEntity {private static final long serialVersionUID = -7124481085999629236L;/*** 商务负责人ID*/@Schema(description = "商务负责人ID")private Long id;/*** 总后台用户ID 关联总后台用户表*/@Schema(description = "总后台用户ID 关联总后台用户表")@JsonSerialize(using = ToStringSerializer.class)private Long userId;/*** 合作学校ID*/@Schema(description = "合作学校ID")@JsonSerialize(using = ToStringSerializer.class)private Long cooperationSchoolId;/*** 删除标识 0. 合作中  1.已停止*/@Schema(description = "删除标识 0. 合作中  1.已停止")private Integer isCooperation;/*** 操作人*/@Schema(description = "商务手机号")private String telephone;@Schema(description = "商务姓名")private String businessUserName;}
