Answer 1

mappedBy 属性在此方法中不完全匹配

 @OneToOne(mappedBy = "sysReportListByReportId")
    public SysReportLayoutUserApply getSysReportLayoutUserApplyByReportId() {
        return sysReportLayoutUserApplyByReportId;
    }

此属性值应该与引用的类对象完全相同，例如sysReportLayoutConfigByLayoutId

检查下面的示例

Model.java 使用 @ManyToOne 和“brand_id”引用 Brand 类

public class Model {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;

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

    @JsonIgnore
    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "brand_id")
    private Brand brand;
 }

Brand.java使用mappedBy引用模型类，其brand值与模型类中的变量名称完全相同

public class Brand {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;

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

    @JsonIgnore
    @OneToMany(fetch = FetchType.LAZY, mappedBy = "brand")
    private Set<Model> models;

}
