所以我在Orika 1.4.6和1.5.1中尝试过这个。我试图将包含Set的对象映射到包含Map的对象。这些类看起来如下......
public class Apple {
private Long id;
private String name;
private Set<Seed> seeds;
}
public class AppleDto {
private Long id;
private String name;
private Map<Long, SeedDto> seeds = new HashMap<Long, SeedDto>();
}
public class Seed {
private Long id;
private String name;
}
public class SeedDto {
private Long id;
private String name;
}
我觉得我正在按用户指南（enter link description here：在“映射嵌套的多次出现元素”下）中的定义正确定义映射...）
factory.classMap(Apple.class, AppleDto.class)
.field("id", "id")
.field("name", "name")
.field("seeds{id}", "seeds{key}")
.field("seeds{}", "seeds{value}")
.register();
factory.classMap(Seed.class, SeedDto.class)
.field("id", "id")
.field("name", "name")
.register();
然而，当我尝试进行映射时，我收到以下错误......
