问题描述

How to correctly map the map using Dozer and annotations 如何使用推土机和注解正确映射地图

Without lists, everything works well 没有列表，一切正常

Dozer version 6.1.0 推土机版本6.1.0

http://dozer.sourceforge.net/documentation/collectionandarraymapping.html How to render b-hint on annotations http://dozer.sourceforge.net/documentation/collectionandarraymapping.html如何在注释上呈现b提示 

@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;
...
}

Everything works fine, but when I try to get a map list, I get an error 一切正常，但是当我尝试获取地图列表时，出现错误

How can I solve this problem without configuring xml? 如何在不配置xml的情况下解决此问题？

来自Lomdok和Dozer的omomibility @Date（@toString）错误

To prevent lombok's ToString() to run recursively the link field should be excluded. 为了防止lombok的ToString()递归运行，应该排除链接字段。 And the same for hashCode() : 与hashCode()相同： 

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