带有注释的推土机地图列表

Question

如何使用推土机和注释正确映射地图

没有列表，一切都很好

推土机版本 6.1.0

http://dozer.sourceforge.net/documentation/collectionandarraymapping.html 如何在注解上呈现 b-hint

@Entity
@Table(name = "PRODUCT_THEME")
@Data
public class ProductTheme implements Serializable {
    @Id
    @GeneratedValue(generator = "PRODUCT_THEME_SEQ", strategy = GenerationType.SEQUENCE)
    @SequenceGenerator(name = "PRODUCT_THEME_SEQ", sequenceName = "PRODUCT_THEME_SEQ", allocationSize = 1)
    @Column(name = "ID", updatable = false, nullable = false)
    @Mapping("id")
    private Integer id;
    @Column(name = "DESCRIPTION", length = 100)
    @Mapping("description")
    private String description;
    @ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinTable(name = "PRODUCT_THEME_IMAGE", joinColumns = { @JoinColumn(name = "THEME_ID", nullable = false, updatable = false) }, inverseJoinColumns = {
                                    @JoinColumn(name = "IMAGE_ID", nullable = false, updatable = false) })

    **@Mapping("imagesList")**

    private List<Images> imagesList;
    @Column(name = "ACTIVE", nullable = false)
    @Mapping("active")
    private Boolean active;
...
}

一切正常，但是当我尝试获取地图列表时，出现错误

不配置xml如何解决这个问题？

Answer 1

Lomdok 和 Dozer 的兼容性 @Date (@toString) 出现错误

Answer 2

为防止 lombok 的 ToString() 递归运行，应排除链接字段。 hashCode() 也一样：

@Entity
@Table(name = "PRODUCT_THEME")
@Data
@lombok.ToString(exclude="imagesList")
@lombok.EqualsAndHashCode(exclude="imagesList")
public class ProductTheme implements Serializable {
    ...
}
