如何使用Dozer和注释正确映射地图

没有列表，一切运作良好

推土机版本6.1.0

http://dozer.sourceforge.net/documentation/collectionandarraymapping.html 如何在注释上呈现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，但当我尝试获取地图列表时，我收到错误

如何在不配置xml的情况下解决此问题？

2 个答案:

答案 0 :(得分：0)

错误来自Lomdok和Dozer的сompatibility@Date（@toString）

答案 1 :(得分：0)

为防止lombok的ToString()以递归方式运行，应排除链接字段。 hashCode()：

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