如何正确使用MapStruct @Mapping 和@Mappings？
How to use MapStruct @Mapping and @Mappings properly?
你好，我的问题是当我 mvn clean package 构建 .jar 文件时，我遇到了一些看起来像这样的错误：
[ERROR] COMPILATION ERROR :

但是当我 运行 我的项目通过引导仪表板右键单击并启动我的项目时它 运行 正常。我的 api 工作正常。我试试看。
首先尝试我的代码如下所示，我的映射器文件如下所示：
@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;
}
这是我扩展的 AuditField class :
@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;
}
这是我的 DTO AuditFieldDto class :
@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 class :
@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;
}
如您所见，AuditField 和 AuditFieldDto 具有相同的字段，但是当我这样做时 运行 mvn clean package 它会给我编译错误，就像我提到的问题的顶部一样。在错误消息中，mapstruct 似乎无法正确找到该字段。然后我尝试删除@Mappings 和@Mapping 注释行，构建成功。看起来很可疑.. 因为当我 运行 使用 Boot Dashboard 时这些注释工作正常。
这是我的 pom.xml :

当我使用 mvn clean package 将项目构建为 .jar 文件时，如果我想使用 @Mappings 和 @Mapping，我在项目中错过了什么？
我认为你错过了 lombok-mapstruct-binding。
我在这里找到了罪魁祸首，但我不确定为什么这样做，这是否正确，因为当我执行此代码时，它起作用了。好的，让我们开始吧，你可以在我的问题中查看我的 mapstruct 版本，这是我解决这个问题的方法：
首先，在我的 AuditField 和 AuditFieldDto 中，如您所见，我有 2 个字段以“public”数据类型写入，起初我将所有字段都写入 public但是后来我的朋友来推荐我将其设为私有，但我不小心没有将其全部设为私有，名为 public Boolean isDeleted; 和 public String reasonDeleted; 的两个字段是 public，这就是为什么错误通过它们，它们工作正常，错误转到我私下编写的另一行。
而我只是 运行dom 悲惨地把它们的数据类型改回了 public，你可以看到有 4 个字段写在私有字段中，它们是
@CreatedDate
private Date createdDate;
@LastModifiedDate
private Date modifiedDate;
@CreatedBy
private String createdBy;
@LastModifiedBy
private String modifiedBy;
所以我在我的 AuditFieldDto 和 AuditField class 中将它们全部更改为 public，我的 AuditField class 的完整代码如下所示：
@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;
@Schema(description = "Alasan di hapus", example = "apa pun alasannya", required = false)
public String reasonDeleted;
@CreatedDate
public Date createdDate;
@LastModifiedDate
public Date modifiedDate;
@CreatedBy
public String createdBy;
@LastModifiedBy
public String modifiedBy;
}
它对我的 AuditFieldDto class 应用相同的方法，看起来像这样：
@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 = "";
public String createdDate;
public String modifiedDate;
public String createdBy;
public String modifiedBy;
}
当我这样做时 运行 mvn clean package 构建成功！我 运行 .jar 文件，它工作！我猜为什么？？？因为这个我坚持了好几天。然后我尝试查看生成的文件，您可以在位于 target/generated-sources/annotations 的项目中找到生成的文件，并细化映射器 class 文件。这是我的，我只举了一个生成代码的例子，因为另一个似乎没有任何问题。
这里是 GENERATED FILE 里面的内容（我们不应该编辑这个文件，只是为了查看）：
@Component
public class ICategoryBpsjMapperImpl implements ICategoryBpsjMapper {
@Override
public CategoryBpsjResponseDto entityToDto(CategoryBPSJ entity) {
if ( entity == null ) {
return null;
}
CategoryBpsjResponseDto categoryBpsjResponseDto = new CategoryBpsjResponseDto();
if ( entity.createdDate != null ) {
categoryBpsjResponseDto.createdDate = new SimpleDateFormat( "dd-MM-yyyy HH:mm:ss" ).format( entity.createdDate );
}
if ( entity.modifiedDate != null ) {
categoryBpsjResponseDto.modifiedDate = new SimpleDateFormat( "dd-MM-yyyy HH:mm:ss" ).format( entity.modifiedDate );
}
categoryBpsjResponseDto.isDeleted = entity.isDeleted;
categoryBpsjResponseDto.reasonDeleted = entity.reasonDeleted;
categoryBpsjResponseDto.createdBy = entity.createdBy;
categoryBpsjResponseDto.modifiedBy = entity.modifiedBy;
return categoryBpsjResponseDto;
}
}
你看到他们在没有获取和设置的情况下访问 属性（我的意思是 getter setter），我认为这是导致我在标记该字段时出错的罪魁祸首作为私有的，如果代码是这样写的，他们将无法访问。现在这就是我解决它的方式。
如果有人有更好的答案，我会接受他们的答案，如果我的代码不正确或不合适，等待它。
你好，我的问题是当我 mvn clean package 构建 .jar 文件时，我遇到了一些看起来像这样的错误：

当我使用 mvn clean package 将项目构建为 .jar 文件时，如果我想使用 @Mappings 和 @Mapping，我在项目中错过了什么？
我认为你错过了 lombok-mapstruct-binding。
我在这里找到了罪魁祸首，但我不确定为什么这样做，这是否正确，因为当我执行此代码时，它起作用了。好的，让我们开始吧，你可以在我的问题中查看我的 mapstruct 版本，这是我解决这个问题的方法：
首先，在我的 AuditField 和 AuditFieldDto 中，如您所见，我有 2 个字段以“public”数据类型写入，起初我将所有字段都写入 public但是后来我的朋友来推荐我将其设为私有，但我不小心没有将其全部设为私有，名为 public Boolean isDeleted; 和 public String reasonDeleted; 的两个字段是 public，这就是为什么错误通过它们，它们工作正常，错误转到我私下编写的另一行。
而我只是 运行dom 悲惨地把它们的数据类型改回了 public，你可以看到有 4 个字段写在私有字段中，它们是
@CreatedDate
private Date createdDate;
@LastModifiedDate
private Date modifiedDate;
@CreatedBy
private String createdBy;
@LastModifiedBy
private String modifiedBy;
所以我在我的 AuditFieldDto 和 AuditField class 中将它们全部更改为 public，我的 AuditField class 的完整代码如下所示：
@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;
@Schema(description = "Alasan di hapus", example = "apa pun alasannya", required = false)
public String reasonDeleted;
@CreatedDate
public Date createdDate;
@LastModifiedDate
public Date modifiedDate;
@CreatedBy
public String createdBy;
@LastModifiedBy
public String modifiedBy;
}
它对我的 AuditFieldDto class 应用相同的方法，看起来像这样：
@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 = "";
public String createdDate;
public String modifiedDate;
public String createdBy;
public String modifiedBy;
}
当我这样做时 运行 mvn clean package 构建成功！我 运行 .jar 文件，它工作！我猜为什么？？？因为这个我坚持了好几天。然后我尝试查看生成的文件，您可以在位于 target/generated-sources/annotations 的项目中找到生成的文件，并细化映射器 class 文件。这是我的，我只举了一个生成代码的例子，因为另一个似乎没有任何问题。
这里是 GENERATED FILE 里面的内容（我们不应该编辑这个文件，只是为了查看）：
@Component
public class ICategoryBpsjMapperImpl implements ICategoryBpsjMapper {
@Override
public CategoryBpsjResponseDto entityToDto(CategoryBPSJ entity) {
if ( entity == null ) {
return null;
}
CategoryBpsjResponseDto categoryBpsjResponseDto = new CategoryBpsjResponseDto();
if ( entity.createdDate != null ) {
categoryBpsjResponseDto.createdDate = new SimpleDateFormat( "dd-MM-yyyy HH:mm:ss" ).format( entity.createdDate );
}
if ( entity.modifiedDate != null ) {
categoryBpsjResponseDto.modifiedDate = new SimpleDateFormat( "dd-MM-yyyy HH:mm:ss" ).format( entity.modifiedDate );
}
categoryBpsjResponseDto.isDeleted = entity.isDeleted;
categoryBpsjResponseDto.reasonDeleted = entity.reasonDeleted;
categoryBpsjResponseDto.createdBy = entity.createdBy;
categoryBpsjResponseDto.modifiedBy = entity.modifiedBy;
return categoryBpsjResponseDto;
}
}
你看到他们在没有获取和设置的情况下访问 属性（我的意思是 getter setter），我认为这是导致我在标记该字段时出错的罪魁祸首作为私有的，如果代码是这样写的，他们将无法访问。现在这就是我解决它的方式。
如果有人有更好的答案，我会接受他们的答案，如果我的代码不正确或不合适，等待它。
