我正在开发一个使用JHipster v2.20.0创建的Web应用程序.使用Eclipse 4.5.0 WTP作为IDE.
Spring配置是基于注释的.
我刚刚将这个拉动与我们的代码合并.
当我尝试在Eclipse中运行应用程序时,我得到以下异常:
[INFO] com.app.tenancy.hibernate.MyCurrentTenantIdentifierResolver - MyCurrentTenantIdentifierResolver.getTenantId(): Couldn't find Company/Tenant for the domain inventario, stopping serving the request
[WARN] org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt

我们试图将DTO1映射到DTO2.Builder,如果mapstruct能识别Builder中的setter但这些没有void返回类型但返回Builder本身以进行流畅的连接,那么它将起作用.
所以这是示例的代码.
我们有两个接口
@Value.Immutable
public interface MammalDto {
public Integer getNumberOfLegs();
public Long getNumberOfStomachs();
}
和
@Value.Immutable
public interface MammalEntity {
public Long getNumberOfLegs();
public Long getNumberOfStomachs();
}
然后我们有了maptruct的Mapper接口:
@Mapper(uses = ObjectFactory.class)
public interface SourceTargetMapper {
SourceTargetMapper MAPPER = Mappers.getMapper( SourceTargetMapper.class );
ImmutableMammalEntity.Builder toTarget(MammalDto source);
}
要使用mapstruct来查找Builder,我们需要一个Factory:
public class ObjectFactory {
public ImmutableMammalDto.Builder createMammalDto() {
return ImmutableMammalDto.builder();
}
public ImmutableMammalEntity.Builder createMammalEntity() {
return ImmutableMammalEntity.builder();
}
}
为了生成代码,编译器插件被指示使用两个注释处理器:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<configuration> …我有一个使用gradle的项目,并将mapstruct作为依赖项之一.每当我试图建立项目时,它就失败了.我想这是因为Mapstruct将生成gradle无法找到的impl类.谁能帮助我如何在intellij IDEA中配置它？
谢谢
我使用以下映射器来映射实体:
public interface AssigmentFileMapper {
AssigmentFileDTO assigmentFileToAssigmentFileDTO(AssigmentFile assigmentFile);
AssigmentFile assigmentFileDTOToAssigmentFile(AssigmentFileDTO assigmentFileDTO);
@Mapping(target = "data", ignore = true)
List<AssigmentFileDTO> assigmentFilesToAssigmentFileDTOs(List<AssigmentFile> assigmentFiles);
List<AssigmentFile> assigmentFileDTOsToAssigmentFiles(List<AssigmentFileDTO> assigmentFileDTOs);
}
我只需要忽略映射为集合的实体的"数据"字段.但它看起来@Mapping只适用于单个实体.另外我注意到生成的方法assigmentFilesToAssigmentFileDTOs只是用于assigmentFileToAssigmentFileDTOfor循环.那有什么解决方案吗？
我从这个来源下载了应用程序https://github.com/springframeworkguru/spring5-mvc-rest/tree/vendor-api 而且我的MapStruct有问题。
@Mapper
public interface CategoryMapper {
CategoryMapper INSTANCE = Mappers.getMapper(CategoryMapper.class);
CategoryDTO categoryToCategoryDTO(Category category);
}
@Data
public class CategoryDTO {
private Long id;
private String name;
}
域类：
@Data
@Entity
public class Category {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
}
服务等级：
@Service
public class CategoryServiceImpl implements CategoryService {
private final CategoryMapper categoryMapper;
private final CategoryRepository categoryRepository;
public CategoryServiceImpl(CategoryMapper categoryMapper, CategoryRepository categoryRepository) {
this.categoryMapper = categoryMapper;
this.categoryRepository = categoryRepository;
}
}
在pom.xml依赖项中，我仅粘贴了两个：
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> …我正在创建一个在我的futere项目中使用Mapstruct的poc.
现在我有一个问题如何将自定义方法映射到特殊目标.
例如,我有以下接口映射器:
@Mapper
public interface ItemMapper {
static ItemMapper INSTANCE = Mappers.getMapper(ItemMapper.class);
@Mappings({ @Mapping(source = "number", target = "itemnumber"),
@Mapping(source = "description", target = "description"),
@Mapping(source = "itemClass.name", target = "ic"), @Mapping(source = "optionPart", target = "option"),
@Mapping(source = "plannerCode.code", target = "plannercode"),
@Mapping(source = "plannerCode.name", target = "planner"),
@Mapping(source = "vendor.buyerCode.name", target = "buyer"),
@Mapping(source = "vendor.buyerCode.code", target = "buyerCode"),
@Mapping(source = "vendor.number", target = "vendor"),
@Mapping(source = "vendor.name", target = "vendorName"), @Mapping(source = "pcsItem", target = "pcs"), …我正在尝试使用 Mapstruct 将源对象映射到目标列表。执行此操作的干净映射结构方式应该是什么？
以下是我的 DTO。
源DTO
@Data
class Source
{
String a;
String b;
String C;
}
目标DTO
@Data
class Target
{
String name;
List<Child> customList;
}
@Data
class Child
{
String attr1;
boolean attr2;
}
我面临映射器类的问题。试图实现如下所示的目标。
public interface CustomMapper
{
@Mapper(target="customList" expression="java(new Child(a,false))"
@Mapper(target="customList" expression="java(new Child(b,true))"
@Mapper(target="customList" expression="java(new Child(c,false))"
Target sourceToTarget(Source source);
}
我不想使用如下所示的qualifiedBy函数来实现此目的，因为所有转换都需要为每个元素进行编码。
List<Child> toList(Source source)
{
List<Child> customList = new ArrayList<Child>();
customList.add(new Child(source.getA(),false));
customList.add(new Child(source.getB(),true));
customList.add(new Child(source.getC(),false));
return customList;
}
我有2个实体：
实体1：
public class Master {
private int id;
private Set<SubMaster> subMasters= new HashSet<SubMaster>(0);
}
public class SubMaster{
private int subId;
private String subName;
}
实体2：
public class MasterDTO {
private int id;
private Set<SubMaster> subMasters= new HashSet<SubMaster>(0);
}
public class SubMasterDTO{
private int subId;
private String subName;
}
我正在使用MapStruct映射器将POJO的值映射到另一个。
public interface MasterMapper{
MasterDTO toDto(Master entity);
}
我能够成功映射Master到MasterDTO。但是，SubMasterin 的嵌套集合Master未映射到in中的对应集合MasterDTO。
谁能在正确的方向帮助我？
嗨我在使用mapstruct从Child Source类设置它时,在DTO中为List操作获取null.有人可以帮我解决这个问题.请在这里找到我的代码
实体类:
public class Source {
int id;
String name;
List<ChildSource> childSource;
//getters and setters
}
public class ChildSource {
String code;
String action;
//getters and setters
}
DestinationDTO:
public class TargetDTO{
int sNo;
String mName;
List<String> actions;
//getters and setters
}
MApper类:
@Mapper(componentModel = "spring")
public abstract class SampleMapper {
@Mappings({
@Mapping(target = "id", source = "sno"),
@Mapping(target = "name", source = "mNAme")
})
public abstract TargetDTO toDto(Source source);
@IterableMapping(elementTargetType = String.class)
protected abstract List<String> mapStringtoList(List<ChildSource> childSource);
protected …使用MapStruct。举个例子：
class Dto {
DtoA a;
DtoB b;
}
class DtoA {
Long id;
//...
}
class DtoB {
Long id;
//...
}
class Entity {
AB ab;
}
如何映射DtoA，并DtoB以AB？
我试过了：
public abstract Entity toEntity(Dto dto);
@Mappings({
@Mapping(source = "a", target = "ab.a"),
@Mapping(source = "b", target = "ab.b")
)}
public abstract AB toABEntity(DtoA a, DtoB b);
已经生成了toABEntity足够的代码*，但未调用该方法。
*很糟糕，因为它首先设置a，然后设置b会创建的新实例ab，因此a会丢失。
