Question

我有一个包含许多子实体的父类。此父类有2个实例。想要将一个实例的数据复制到另一个实例（忽略所有子实体中的'id'属性）

----为了简洁起见，隐藏了吸气剂和塞特剂

public class IdBean {
    private Long id;
}

public class City extends IdBean {
    private String name;
}

public class Country extends IdBean {
    private String name;
    private List<City> cities;
}

public class Student extends IdBean {
    private String name;
}

public class School extends IdBean {
    private String name;
    private List<Student> students;
    private List<Country> countries;
}

@MapperConfig(mappingInheritanceStrategy = MappingInheritanceStrategy.AUTO_INHERIT_FROM_CONFIG)
public interface SchoolCentralConfig {

    @Mapping(ignore = true, target = "id")
    IdBean updateBeanEntityFromDto(IdBean dto);
}

@Mapper(config = SchoolCentralConfig.class)
public interface SchoolMapper {
    SchoolMapper INSTANCE = Mappers.getMapper( SchoolMapper.class );
    @Mapping(target = "companies.id", ignore = true )
    void updateSchoolFromDto(School schoolDTO, @MappingTarget School      schoolEntity);
}

我想忽略所有嵌套字段中的所有'id'属性。

Answer 1

var settings = new JsonSerializerSettings { ContractResolver = new ExcludeObsoletePropertiesResolver() }; var json = JsonConvert.SerializeObject(foo, settings);尚不适用于嵌套方法。

您可以做的是同时为MappingInheritanceStrategy.AUTO_INHERIT_FROM_CONFIG和Country写一个签名。然后它将起作用。

所以：

mapstruct-更新现有的bean-忽略所有子/嵌套bean（数组列表，集合等）中的“ id”字段
