嗨，我的问题是，当我做mvn clean package来构建.jar文件时，我遇到了一些错误，如下所示：

[ERROR] COMPILATION ERROR :

但是当我通过引导仪表板运行我的项目时，右击并启动我的项目，它将正常运行。我的api很好用。我做了一些尝试。

首先，我的代码如下所示，我的mapper文件如下所示：

@Mapper(componentModel = "spring")
public interface ICategoryBpsjMapper {

    ICategoryBpsjMapper INSTANCE = Mappers.getMapper(ICategoryBpsjMapper.class);

    @Mappings({ 
        @Mapping(target = "createdDate", dateFormat = "dd-MM-yyyy HH:mm:ss"),
        @Mapping(target = "modifiedDate",dateFormat = "dd-MM-yyyy HH:mm:ss")})
    CategoryBpsjResponseDto entityToDto(CategoryBPSJ entity);

    CategoryBPSJ DTOEntity(CategoryBPSJDto dto);
    
    CategoryBPSJ updateEntityFromDto(CategoryBPSJDto dto, @MappingTarget CategoryBPSJ entity);
    
    List<CategoryBpsjResponseDto> entityToDto(List<CategoryBPSJ> entityList);
    
    List<CategoryBPSJ> DTOEnity(List<CategoryBPSJDto> dtoList);

}

这是我的实体：

@Data
@Entity
@Audited
@EntityListeners(AuditingEntityListener.class)
@EqualsAndHashCode(of = "id")
@ToString(of = {"id"})
@Table(name = "msCategoryBPSJ", uniqueConstraints = {
    @UniqueConstraint(name = "uk_categoryBPSJName", columnNames = { "categoryBPSJName" })})
public class CategoryBPSJ extends AuditField implements Serializable {

    private static final long serialVersionUID = 8062436315663828938L;

    @Schema(description = "Id merupakan primary key dan harus disertakan ketika edit, tipe datanya Long", example = "0", required = true)
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Schema(description = "kode kategori pengiriman", example = "BPSJCTH1", required = true)
    @NotBlank(message = "Tidak Boleh Kosong")
    private String categoryBPSCode;

    @Schema(description = "nama kategori pengiriman", example = "Toko/Gudang Tujuan Tutup", required = true)
    @NotBlank(message = "Tidak Boleh Kosong")
    private String categoryBPSJName;
    
}

下面是我扩展的AuditField类：

@MappedSuperclass
@Data
@Audited
@EntityListeners(AuditingEntityListener.class)
@JsonIgnoreProperties(value = { "createdDate", "modifiedDate", "isDeleted" }, allowGetters = true, allowSetters = false)
public class AuditField implements Serializable {

    private static final long serialVersionUID = 6025082509703710749L;

    @Schema(description = "Status di hapus", example = "false", required = false)
    public Boolean isDeleted = false;

    @Schema(description = "Alasan di hapus", example = "apa pun alasannya", required = false)
    public String reasonDeleted = "";

    @CreatedDate
    private Date createdDate;
    @LastModifiedDate
    private Date modifiedDate;
    @CreatedBy
    private String createdBy;
    @LastModifiedBy
    private String modifiedBy;

}

下面是我的DTO AuditFieldDto类：

@Data
public class CategoryBpsjResponseDto extends AuditFieldDto implements Serializable {

    private static final long serialVersionUID = -422185482845439241L;

    @Schema(description = "Id merupakan primary key dan harus disertakan ketika edit, tipe datanya Long", example = "0", required = true)
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public Long id;

    @Schema(description = "kode kategori pengiriman", example = "BPSJCTH1", required = true)
    @NotBlank(message = "Tidak Boleh Kosong")
    public String categoryBPSCode;

    @Schema(description = "nama kategori pengiriman", example = "Toko/Gudang Tujuan Tutup", required = true)
    @NotBlank(message = "Tidak Boleh Kosong")
    public String categoryBPSJName;

}

这是我的AuditFieldDto课程：

@Data
public class AuditFieldDto implements Serializable {

    private static final long serialVersionUID = 3758121148184815303L;

    @Schema(description = "Status di hapus", example = "false", required = false)
    public Boolean isDeleted = false;

    @Schema(description = "Alasan di hapus", example = "apa pun alasannya", required = false)
    public String reasonDeleted = "";

    private String createdDate;
    
    private String modifiedDate;
    
    private String createdBy;
    
    private String modifiedBy;

}

正如您所看到的，AuditField和AuditFieldDto有相同的字段，但是当我运行mvn clean package时，它会给我编译错误，就像前面提到的问题一样。在错误消息中，mapstruct似乎找不到正确的字段。然后我尝试删除@映射和@ the注释行，构建就成功了。看起来很可疑..。因为当我使用Boot运行时，仪表板可以很好地处理这些注释。

这是我的pom.xml：

当我用.jar将项目构建到mvn clean package文件时，如果我想使用@映射和@映射，我在我的项目中遗漏了什么

java

spring

spring-boot

mapstruct

我想你错过了lombok-mapstruct绑定。
